    influence of alcohol or drugs may result in serious injury.
.   Keep all persons and pets away from the mowing area.
Child Safety
Serious injury or death can occur when children fall off the mower and are
run over by the machine, or when children run or fall in the path of a
mower and are run over.
l  Allowing children to ride as passengers on the riding mower can be
   dangerous.
l  Keep children indoors and supervised at all times when any outdoor
   power equipment is being used nearby. Young children move quickly
   and are attracted to the mower and the mowing activity especially if
   they have been given rides before.
l  Never assume children will remain where you last saw them. Be alert
   and turn the mower off if children enter the area. Use extra care when’
   approaching corners, shrubs, and trees that might shield children from
   sight.
l Children should never be allowed to operate the riding mower, even
   under adult supervision.
                                                                            5
Cutting Blade Hazard
The cutting blades are sharp, and they turn at high speed. Accidental con-
tact can cause serious injury.
l  Keep your hands and feet away from the mower deck while the engine
   is running.
l  Stop the engine, disengage the Power Take Off (P.T.O.) clutch and
   remove the key before inspection or maintenance of the deck or blades.
l  Disconnect the spark plug cap to prevent any possibility of accidental
   starting. Wear heavy gloves to protect your hands from the blades
   when cleaning out the mower deck, or when inspecting or replacing the
   blades.
Objects hit by the cutting blades can be thrown from the mower with great
force, and may cause serious injury.
l  Before mowing, clear the mowing area of sticks, stones, dog bones,
   and other litter and loose objects. Mow only in daylight, or in well-lit
   areas at night, so you can see and avoid objects in the grass.
l  Before operating the mower, be sure the side discharge guard is down,
   or that the optional grass catcher bags and discharge chute are in place.
l  Disengage the Power Take Off (P.T.O.) lever to stop the blades before
   crossing a gravel driveway or any other area with loose stones.
l  Always inspect the mower for damage after striking a foreign object.
   Repair or replace any damaged parts before continued use.
l  Broken pieces thrown from a worn or damaged blade can cause serious
   injury. Always inspect the blades before using the mower.
6

FUEL
m
Gasoline is extremely flammable, and gasoline vapor can explode. Use ex-
treme care when handling gasoline. Keep gasoline out of reach of children.
l  Refuel in a well ventilated area with the engine stopped. Keep flames
   and sparks away, and do not smoke in the area.
l  Allow the engine to cool before refueling. Fuel vapors or spilled fuel may
   ignite.
l  Refuel carefully to avoid spilling fuel. Avoid overfilling the fuel tank
   (there should be no fuel in the filler neck). After refueling, tighten the
   filler fuel cap securely. If any fuel was spilled, make sure the area is dry
   before starting the engine.
0 After use,. turn the fuel valve OFF, and park the riding mower on a level
   surface. Be sure the storage area is well ventilated, do not allow flames
   or sparks in the storage area.
Fuel Recommendation
Occasionally you may hear light spark knock while operating under heavy
loads. This is no cause for concern. It simply means your engine is
operating efficiently.
20
GASOLINES CONTAINING       ALCOHOL
Before buying fuel from an unfamiliar station, first determine if the fuel
contains alcohol; if it does, find out the type and percentage of alcohol
used.
                                                                      21
AIR CLEANER
Check that the air cleaner elements are clean and in good condition. A dir-
ty air cleaner will restrict air flow to the carburetor, reducing engine perfor-
mance. A damaged air cleaner will allow dirt to enter the engine, causing
rapid engine wear.
1. Raise the rear body and remove the two wing nuts to remove the air
   cleaner cover and air cleaner elements.
2. Inspect the air cleaner elements. Clean or replace the cleaner if
   necessary. If the air cleaner elements need cleaning, follow the pro-
   cedure described on page 46.
3. Reinstall the air cleaner elements and a,ir cleaner cover. Tighten the
   wing nuts securely.
22
BATTERY
Raise the rear body and check the battery electrolyte level.
The electrolyte level must be kept between the UPPER and LOWER level
marks. If the electrolyte level is near the LOWER mark, remove the battery
filler caps and carefully add distilled water to the upper level line (see page
49).
                                                                          23
 TRANSMISSION FLUID
 Check,the transmission fluid with the riding mower parked on level ground
 and the transmission at ambient temperature.
 NOTE: HST fluid changes its volume with changes of temperature. The
 upper and lower marks are calibrated for HST fluid temperature between
 32OF (OOC) and 68OF (2OOC). Within this temperature range, the oil level
should be between the upper and lower marks on the reservoir.
If the fluid temperature is below 32OF (O°C), the transmission fluid level
may be below the lower mark on the reservoir. To measure the level, start
the engine and warm the transmission fluid.
If the fluid temperature is above 68OF f20°C), the level may be above the
upper mark on the reservoir. This is normal and does not indicate a
problem.
Make sure the fluid level is between the upper and lower marks on the
reservoir. If the level has dropped close to or below the lower mark and the
fluid temperature is between 32OF (OOC) and 68OF f20°CI, add transmis-
sion fluid until it reaches the upper mark. Do not overfill..
Required transmission fluid:

BRAKE
Inspect brake lining condition every time the riding mower is used.
Firmly set the parking brake, and then check the position of the brake wear
indicator. If the indicator is near the wear limit, take the riding mower to an
authorized Honda riding mower dealer for repair.
m            Operating the riding mower when brake linings are at or past
the service limit can cause brake failure and possible injury.

   remove the cutter deck, and thoroughly.inspect the blades (see cutter
   deck removal instructions on page 52). Dull blades can be sharpened,
   but blades that are worn out, bent, cracked, or otherwise damaged
   must be replaced. If the blades need sharpening or replacement, take
   the cutter deck to your authorized Honda riding mower dealer. Or, if you
   have the proper tools, you can remove and install the blades yourself
   (see blade removal and installation instructions on pages 58-59).
 Broken pieces thrown from a worn or damaged blade can cause serious in-
jury. Always inspect the blades before using the mower.
    IMPORTANT   NOTICE ]
l    Use a genuine Honda replacement blades, or equivalent.
l    To reduce the possibility of weakening the blades, or causing imbalance
     or poor cutting performance, sharpening should be performed by an
     authorized Honda riding mower dealer.

     seen hazards may cause loss of control or damage the riding mower.
l    In tall grass, first mow with the cutter deck fully raised (3 l/2’); this will
     help expose any hidden obstacles. When you are sure the area is com-
     pletely cleared, re-mow at the desired height.
l    If the riding mower should accidently gets caught by an unseen object,
     (holes, roots, or rocks) do not try to ride over the obstruction or turn the
     steering wheel to free the mower. This will damage the steering
     mechanism or cutter deck.
l    Operating the riding mower near the edge of a ditch or an embankment
     could cause the mower to tip or roll-over.
l    Avoid sharp turns or sudden stops on sloping surfaces. Avoid backing
     down or rapid acceleration on sloping surfaces. Both of which could
     cause loss of control.
l    Stop the engine before removing the grass bags or cleaning the
     discharge chute.
Mowing tips
l For good mowing conditions, the grass should not be wet, but the
  ground should be damp to control dust.
* If dust is a problem, water the lawn the day before mowing, allowing
  the grass to dry while the ground remains moist.
l Always allow the grass to dry before cutting. Cutting wet grass will
  cause the cutter deck,or the discharge to clog, resulting in poor cut
  quality.
                                                                               33
l   Always engage the P.T.O. before selecting the desired mowing speed
    to avoid leaving uncut grass. Engaging the P.T.O. in tall uncut grass
    may cause the engine to stall.
 l  Mow at full throttle with the transmission in the desired mowing speed
    for the best cut quality and performance. Mowing in a medium or low
   throttle setting will affect the performance and cut quality.
l  After selecting the desired mowing speed, you should remain in that
   range when mowing for the best results. Avoid making rapid mowing
   speed changes from slow to fast when mowing, this will affect-cut
   quality.
. Avoid shifting to the transport range when mowing. Mowing in the
   transport range is not recommended, as this will affect cut quality.
   Transport range should only be used to drive to and from the mowing
   area.
l  If the lawn is thick, lush, or uneven, lower the mowing speed, raise the
   cutter deck and cut a narrower swath.
l  If the lawn has grown too tall, lower the mowing speed, raise the cutter
   deck height and mow twice (first at a high cutter deck setting, then at
   the desired height).
l  For a finish trim cut, lower the mowing speed and mow the lawn
   counterclockwise around trees, post, flower beds, sprinklers and other
   obstacles.
l  An adjustment of the cutter deck may be required if the grass does not
   cut properly. Have the cutter deck height inspected and adjusted by an
   authorized Honda riding mower dealer. First, verify the deck is clean
   and the blades are in good condition.
l  If mowing on a sloping surface, always drive up and down the face of
   the grade. Never turn around or drive across the face of the slope; this
   may cause the mower to tip over.
. To prevent tipping or loss of control, always reduce the ground speed
   and exercise extreme caution when operating on slopes and uneven
   surfaces.

Starting the riding mower
1. Set the cutter deck height adjusting lever to the desired cutting height.
SET BUTTON
    NOTE: For best cut quality, and performance always use full throttle.
    Use the shift lever to select the.desired mowing speed range.
                                                                        35
3. Move the P.T.O. lever to the ON (Engaged) position.

Cutting patterns
These cutting    patterns   are only recommended      for a flat, level lawn
surface.
l In a small area
l In a large area
    ‘The first round of cuts is the key to making a neat finish. First, make 2
     or 3 turns in a clockwise direction. As you reach the center of the area,
     turn to the right and continue cutting in the reverse direction until you
     have finished the upper half of the area. Cut the grass in the remaining
     half in a counterclockwise direction.
                                                                          37
     Mowing on unsquare areas
 If your mowing area is not square or four-sided, divide the area into
 several blocks so you can mow in a neat mowing pattern.
OVedapping in straight-a-ways
 When cutting in curves and turns, shift to a slower speed and be sure to
 overlap the previous cut by 50%, or approximately half the width of the
 mower.
38
Stopping on a hill
     Depress the foot the brake to the floor (shift lever returns to “N”).
::   Move the P.T.O. lever to the OFF (disengaged) position.
3.   Set the parking brake.
Moving the shift lever too quickly while starting uphill may cause the
mower to tip over. Move the shift lever slowly.

High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be too rich.
Performance will decrease, and fuel consumption will increase. A very rich
fuel mixture may also foul the spark plugs and cause hard starting.
When the carburetor is modified for good high altitude operation, the
air/fuel mixture will be too lean at low altitude. Performance will decrease,
the engine will overheat.
                                                                         41

Battery Service
n Refilling battery fluid
If the riding mower is operated with insufficient battery electrolyte, sulfa-
tion and battery plate damage will occur.
If iapid loss of electrolyte is experienced, or if your battery seems to be
weak, causing slow starting or other electrical problems, see your
authorized Honda riding mower dealer.
Raise the rear body and check the electrolyte level in each battery cell. Fill
the battery with distilled water to the upper level line. Never overfill the
battery.
m            Batteries produce explosive gases. Flames or sparks can cause
an explosion, causing serious injury or blindness. Keep flames and sparks
away and adequate ventilation when charging.
l  CHEMICAL HAZARD: Battery electrolyte contains sulfuric acid. Con-
   tact with eyes or skin, even through plathins, may cause severe burns.
   Wear a faceshield and protective clothing.
l  Keep flames and sparks away, and do not smoke in the area.
   ANTIDOTE: If electrolyte gets into your eyes, flush thoroughly with
   warm water for at least 15 minutes and call a physician immediately.
l  POISON: Electrolyte is poison.
   ANTIDOTE
   - External: Flush thoroughly with water.
   - Internal: Drink large quantities of wate; or milk.
      Follow with milk of magnesia or vegetable oil, and call a physician
      immediately.

         4.5-5.5   kg-m (32.55-39.78      ft-lb).
                                                                                59
Spark arrester maintenance (optional pert)
m
             The muffler becomes very hot during operation and remains
hot for a while afterthe engine stops. Be careful not to touch the muffler
while it is hot. Allow it to cool before proceeding.
The spark arrester must be serviced every 100 ‘hours to maintain its
efficiency.
1. Remove the four 6 mm bolts and 8 mm bolt that hold the shift lever
   guide stay, and then remove the stay and collar.
2. Remove the two 6 mm bolts from the exhaust pipe tip. Remove the ex-
   haust pipe tip, spark arrester and gasket (be careful not do damage the
   spark arrester screen).
3. Use a wire brush to remove carbon deposits from the spark arrester
   screen.
NOTE: Inspect the spark arrester screen for holes or tears. Replace it if it
is damaged.

Fuse replacement
The 5 A main fuse is located near the battery on the positive terminal.
When frequent fuse failure occurs, it usually indicates a short circuit or an
overload in the electrical system. See your authorized Honda riding mower
dealer for repair.
To replace fuse pull the old fuse out of the clips with your finger. Push a
new fuse into the clips.
                                  5 A MAIN FUSE
                                        I
Turn the engine switch OFF and remove the key before checking or replac-
ing fuses to prevent accidental short-circuiting.
                                                                         61
     8.   STORAGE
     m
                 Contact with a hot engine or exhaust system can cause serious
     burns or fires. Let the engine cool before storing.
     The following steps should be taken to protect the riding mower whenever
     it will be stored for longer than 30 days.
     1. Drain all gasoline   from the   fuel tank   into an approved   gasoline
        container.
     Turn the fuel valve ON, loosen the carburetor drain screw, and drain the
     fuel into an approved gasoline container. After draining tighten the drain
     screw securely.
,m
                Gasoline is extremely flammable, and gasoline vapor can ex-
     plode, causing serious injury or death. Use extreme care when handling
     gasoline.
Keep flames and sparks away, and do not smoke in the area.
     NOTE: If gasoline is not drained before storage, fuel system damage may
     result.
     62
2. Change the engine oil (see page 451.
NOTE: If the riding mower will be stored for longer than 3 months, raise
the rear body and remove the spark plug and pour three tablespoons (ap-
proximately 1 oz.) of clean motor oil into the cylinder.
Place the P.T.O. lever in the OFF position and the shift lever in the N posi-
tion. With the parking brake applied, lower the cutter deck to the bottom.
Reaching from the rear of the mower, grasp the primary belt at point A,
and slowly pull it toward you to turn the engine. Reinstall the spark plug.
3. Remove the battery and store in a cool, dry place. Recharge it once a
   month.
4. If equipped with the optional grass catcher, be sure to empty and clean
   the bags before storage.
5. Remove the cutter deck (see pages 52-54).
6. Turn the cutter deck upside down. Clean the underside of the deck with
   water, and dry thoroughly.
                                                                         63
 7. For longer service and greater efficiency, keep the underside of the
    mower housing clean and free of accumulated grass clippings by
    washing it down with a hose after use and/or cleaning it with a wire
    brush and scraper. Remove any rust and apply a rust-resistant paint.
    Cleaning and rust prevention are especially important before seasonal
    storage.
 6. Reinstall the cutter deck by reversing the removal procedure.
 9. Store the riding mower on a level surface in a dry, dust-free area with
    the parking brake lever set.
10. Cover the riding mowerto keep out dust.
11. Check tire air pressure regularly during storage and inflate if
    necessary.
1. Check the battery electrolyte level (see page 23). Fully recharge the
   battery, and install it in the riding mower.
2. Remove the spark plug and check that it is clean and properly gapped
   (see pages 47-46).
   Turn the engine a few revolutions with the starter motor before
   reinstalling the spark plug.
3. Thread the spark plug in as far as possible by hand, then tighten it l/8
   to l/4 turn further with the plug wrench.
4. Check the engine oil level (see page 18).
5. Fill the fuel tank, and start the engine by following the starting instruc-
   tions (see pages 30-31 I.
NOTE: If the cylinder was coated with oil, the engine will initially smoke
at start up; this is normal.
