• Watch for traffic when operating near or crossing roadways.
• Use extra care when loading or unloading the unit into a trailer or
truck.
• Keep in mind the operator is responsible for accidents occurring to

 SAFETY
• Adjust pattern before operating.
• Do not touch parts which may be hot from operation. Allow such
parts to cool before attempting to service the unit.
• Before using, always visually check that hardware is present, intact
and secure. Replace worn or damaged parts.
• Never operate the machine with damaged guards, or without safety
protective devices in place.

maintenance guidelines
• Maintain or replace safety and instruction decals/labels as neces-
sary.
• Never run a unit in an enclosed area.
• Keep nuts and bolts tight and keep equipment in good condition
• Never tamper with safety devices. Check their proper operation
regularly and make necessary repairs if they are not functioning
properly.
• Keep unit free of debris and build-up. Clean up any oil spillage.
• Stop and inspect equipment if you strike an object. Repair, if neces-
sary, before restarting.
• Never make adjustments or repairs with the engine running unless
specified otherwise in the engine manufacture’s manual.
• Components are subject to wear, damage, and deterioration.
Frequently check components and replace with the manufacturer’s
recommended parts, when necessary.
• Check control operation frequently. Adjust and service as necessary.
• Use only factory authorized parts when making repairs.
• Always comply with factory specifications on all settings and adjust-
ments.
• Only authorized service locations should be utilized for major service
and repair requirements.
• Never attempt to make your own repairs on this unit unless you
have been properly trained. Improper service procedures can result
in hazardous operation, equipment damage and voiding the manu-
facturer’ warranty.
• Stop engine on tractor and set parking brake before performing any
adjustments on the machinery.
• Escaping hydraulic fluid under pressure can have sufficient force to
penetrate the skin, causing serious injury. Before operation, be sure
that all hydraulic connections are tight and hoses are not damaged.
Relieve pressure in system before making adjustments.

shoes will also prolong the life of the cutting edge.
SKID SHOE ADJUSTMENT b. Raise plow high enough to place adequate supports of suf-
ficient height below it to allow skid shoe removal.
See Figure 1.
c. Lower plow onto supports.
1. After the plow is mounted to the prime mover, park the unit on a
flat, level surface; preferably concrete or asphalt. d. Remove the lynch pin from top of skid shoe shaft.
2. Shut off prime mover and apply parking brake. e. Slide skid shoe out of housing mount while retaining all
washers and/or spacer located on top of mount.
NOTE: The cutting edge mounting position is fixed and cannot be
adjusted. Raising (retracting) the skid shoes will increase the cutting edge con-
tact, causing more scraping of the ground.
3. Adjust the skid shoes so that the plow cutting edge, mounted on
the bottom front of plow blade, has light contact along the full Lowering (extending) the skid shoes will decrease the cutting edge

IMPORTANT! The spacer/washers placement must be identical on
both skid shoes to ensure the plow is level.
NOTE: Spacer is 1-1/2” thick. Washers are 1/8” thick. Any combi-
nation of the spacer and washers positions is allowable.
f. Lower the skid shoe (raises cutting edge) by adding spacer/
washers to shaft.
g. Raise the skid shoe (lowers cutting edge), by amount mea-
sured in step a, by removing spacer/washers from shaft.
h. Install skid shoe into mount and hold fully raised.
9. Install remaining spacer/washers on skid shoe shaft, above
mount.
10. Install lynch pin through top end of skid shoe shaft.
11. Lower plow to ground and verify cutting edge contact (gap).
12. Run the unit forward for about 10 feet in the operating position.
Stop, lift plow and then back the unit away. The ‘cleaned’ portion
of the surface should show minimal contact from the cutting
edge and a trace amount from the skid shoes.

 LIMITED WARRANTY

Limited Warranty: Subject to the limitations set forth herein, M-B Companies, Inc. (“M-B”) warrants its products to be free
from defects in material and workmanship for a period of twelve (12) months from the date of delivery of the product to its
original owner, except that the warranty is twelve (12) months solely for the following products: Truck Mounted Pavement
Marking Equipment, Airport Snow Removal Products, Attachment Products, Brushes, MSV Multi-Service Vehicles. Parts
shall have a ninety (90) day warranty. This warranty is not transferable without the written consent of M-B.

Notice: M-B’s obligations under this Limited Warranty are conditioned on M-B receiving, within the warranty period,
written notice from Buyer specifying the nature of any alleged defect and requesting corrective action by Seller.

Remedies: M-B, at its option, will repair or replace, or provide a credit to Buyer for, defective warranted items. If
requested by M-B, products or parts for which a warranty claim is made shall be returned, transportation prepaid, to M-B’s
factory. Buyer shall not return any product for repair, replacement or credit without M-B’s advance written consent.

Other Manufacturer’s Warranty: On products furnished by M-B, but manufactured by any other manufacturer, the
warranty of said manufacturer, if any, will be assigned to Buyer, if the said warranty is assignable. However, M-B does
not represent or guarantee that such manufacturer will comply with any of the terms of the warranty of such manufacturer.

Exclusions: Any improper use, operation beyond capacity, or substitution of parts not approved by M-B, or alteration or
repair by others in such a manner as in M-B’s judgment materially and/or adversely affects the product shall void this
warranty. This warranty does not apply to defects caused by damage or unreasonable use while in the possession of the
owner, including but not limited to: failure to provide reasonable and necessary maintenance, normal wear, routine tune
ups or adjustments, improper handling or accidents, operation at speed or load conditions contrary to published
specifications, improper or insufficient lubrication, or improper storage.

Seller manufactures power brooms that mount to many makes and models of equipment. Seller attempts to ensure that
the mounting frames fit correctly. However, the large number of tractor models, types and options currently available,
compounded by frequent manufacturer design changes, may prevent Seller from supplying a frame that fits every unit
correctly. Therefore, unless Buyer supplies drawing which detail the attachment points on the specific unit to which the
broom will be mounted, Seller will not be responsible for the fit of the mounting frame.

The batteries, tires, rubber material, brushes and material normally consumed in operation, and major components such
as engines, air compressors, and hydraulic pumps and motors are excluded from this warranty but may be covered to the
extent of any warranty received by M-B from its supplier if permitted by the terms of such warranty.

Limitations of liability: M-B shall not be liable for any incidental, consequential, punitive or special damages of any kind,
including, but not limited to, consequential labor costs or transportation charges in connection with the repair or
replacement of defective parts, or lost time profits or expense which may have accrued because of said defect.

M-B disclaims all other warranties, whether express or implied, including but not limited to any implied warranty of
merchantability or fitness for a particular purpose. This warranty is exclusive remedy of buyer. This warranty cannot be
extended, broadened or changed in any respect except in writing by an authorized officer of M-B.

Notwithstanding anything in this warranty is to the contrary, in no event shall M-B’s total liability hereunder exceed the
purchased price of the particular product.
