Welding
In case of a structural repair of the equipment, when
welding may be needed, consult the dealer for
recommended instructions.
When welding on the attachment the following steps
must be taken:
• Make sure that fire-extinguishing equipment is
available.
• Clean the area around the welding area to
eliminate any fire hazard.
• Connect the ground wire so the welding current
does not pass over any bushings.
• Place the ground wire as close to the welding area
as possible.

Modifying the equipment

It is not approved to:
• Modify the equipment without the consent of
HULTDIN SYSTEM AB.
• Alter the function of the equipment without the
consent of HULTDIN SYSTEM AB.
• Use spare parts other than original HULTDINS
parts.

Chain shot hazard

Operator and bystander safety
Because of the high speeds, high stress, heavy loads, wear
factors and varying levels of repair and maintenance given
to saw-chain based machines, there is a possibility that
chain or chain pieces can be thrown from the machine at
high speed and enormous energy. Operators and
bystanders are exposed to a risk of serious injury.

Machines should be designed with appropriate guards and

shields, and care should be taken to minimize the exposure
of users and bystanders to the cutting plane of the saw.

Warning!
There is risk of serious injury or death to machine
operators and bystanders from “Chain Shot”, which
is the high-speed ejection of chain parts that can
occur in the event of a derailed or a broken chain. For
maximum protection, machines should be equipped
with an energy-absorbing chain shot guard.

Product description

Together with its range of accessories, Hultdins patented Labeling

SuperCut 100 saw unit is a comprehensive alternative for
all applications with demands on functionality, reliability, The SuperCut 100 is labeled with serial number according to
service-friendliness, economy and the environment. the following figure.See Fig. 3.
SuperCut 100 is a complete unit with integrated feed The feed out angel is identified with grooves on the feed out
cylinder, well protected from external damage. It has been cylinder, 1 groove for 80° feed out and 2 grooves for 95°
designed for use with hydraulic motors of the type VOAC feed out angle.
F11 - 10 or, alternatively, F11 - 19. The saw motor bracket
is assembled in ball bearings in the saw unit so that the
hydraulic motor is stationary when the saw is fed out. The
saw bar is returned hydraulically with oil.
In its standard version, the SuperCut 100 is equipped with
automatic hydraulic chain tensioning and an integrated
lubrication pump that distributes lubricant to the chain
during the complete sawing operation.
The lubrication pump delivers a maximum volume of 6.5
ml and the process can easily be adapted to specific
lubricating requirements with a number of different
pumps. All the lubrication oils found on the market can be
used.
All this in combination gives good saw bar, chain and oil Grooves
economy.
With the accessories that are available for the SuperCut Serial Number
100, you can easily design an integrated unit consisting of
the saw unit, saw motor manifold, pressure regulating
valve kit and colour marking kit.
Air and lubrication oil tanks are available as extra

accessories, and the SuperCut 100 can be equipped with a
saw home detector sensor and a cut control kit as options.
The cut control kit is used in combination with a
computerized bucking device and limits the angle to
which the saw bar is fed out in relationship to the diameter
of the tree.

INITIAL STARTUP

Adjusting chain tension pressure

If the chain jumps off the bar while sawing, the problem
might be either air in the tensioning system, or that the
tensioning pressure is too low.
To rectify that problem, start with bleeding the system.
See Bleeding chain tension system
If the problem still occurs, the tensioning pressure might
have to be adjusted . Tensioning pressure is measured at
the pressure test point for the pressure regulating valve,
If adjustment is required, do as descibed below.

MAINTE NANCE INSTRUCTIONS

Lubrication
The saw unit should be lubricated every 8 to 200 hours of
operation depending on the conditions that the unit is
working under. The unit has 2 lubrication points as shown
here. See Fig. 56. 2
Note!Use a mineral oil based grease thickened with,
or mixable with a lithium soap. The grease should be
classified as L-XCCIB2 according to ISO 6743-9. 1
Molybdendisulfid content max 3 %. Base fluid
viscosity 170 to 220 cSt at 40°C. NLGI class2.

Make sure at daily maintenance of the saw attachment that
nothing abnormal has occurred with the saw unit
regarding fastener joints and hydraulic hoses.

Strainer for chain lubrication

The strainer in the lubrication oil pump should be
disassembled and cleaned at least every 1000 hours of
operation or when necessary.
