Safety instructions
This page describes important safety instructions, which
the operator’s of Hultdins SuperFell, SuperSaw and
SuperCut attachments should have a good knowledge of
before the equipment is used.
This manual should be available at all times so that the
operator is able to follow safety regulations and the
procedures of maintenance activities..
Note! Read carefully and understand the following
information with concerns to safe operation practices
before operating this equipment.
Important!
The owner and the operator are responsible for
following all safety regulations and that the machine
is safely equipped.
Important!
Check the machine for damages at the beginning of
each shift.
Important!
Inspect and lubricate the unit at the beginning of each
shift. Tighten all fasteners regularly.
Important!
All service and repairs should be carried out by
qualified personnel or an authorized repair shop with
suitable tools and lifting devices.
Important!
When working on the saw chain always ensure the
engine is shut off and wear safety gloves to prevent
injuries. Remove the saw chain when making any
adjustments or servicing the saw unit.
Important!
Never adjust any hydraulic pressures without using a
pressure gauge.
Important!
Consider the environment. Plug all connections to
avoid unnecessary spill of oil.
Warning!
The hydraulic input of the equipment must not
exceed the recommended maximum rating as
structural failure could occur, resulting in injury and
damaged equipment.
Warning!
Before performing any maintenance or service work,
lower the attachment to the ground and shut off the
engine. Turn off any master shut-offs and do not
allow personnel in the cab.
Warning!
Keep all windows and doors securly closed when
operating.
Warning!
Never touch or stand close to the pressurized
cylinders and hydraulic hoses.
Warning!
The attachment has sharp edges. Use proper
wrenches and protective gloves when working on the
attachment.
Fig. 1 The operating area of the saw attachment and the
recommended safety distance
90 meters/300 feet
Warning!
When operating this equipment ensure all other
personnel remain at least 90 meters (300 feet) clear
of the machine. Turn the machine off immediately if
anyone enters this safety zone.
Warning!
Training or demonstration of this equipment should
be performed from an operator´s cab approved by
national regulations. Observers should always
remain at least 90 meters (300 feet away).
Warning!
Always use High Speed saw chains with 3/4” pitch
saw units.

SAFETY INSTRUCTIONS
en010501_sc.FM Safety instructions 5
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.

FUNCTIONAL DESCRIPTION
18 SuperCut 300 en011105b_sc300.FM
Functional description
Chain lubrication system
The SuperCut 300 is equipped with a lubrication oil pump
integrated with the feed out cylinder. The lubrication oil
pump supplies oil via a piston operation to the saw chain
during the entire feed out process.
The lubrication oil pump is fed with oil from the oil tank
(1), trough the inlet check valve (2) and to a reservoar in
the piston rod (3).
When the saw bar (8) is fed out, the oil goes through the
outlet check valve (4), via a hydraulic hose (5) to the
swivel in the saw motor (6) and finally through the bar
holder (7) to the saw bar (8).
The purpose of the pressure relief valve (9) is to limit the
pressure in the lubrication circuit to prevent damages on the
sviwel seals in the saw motor. The cracking pressure of the
valve is between 3.0 to 5.0 MPa.
The supply of oil is proportional, which means that the
volume of oil supplied depends on how much the saw bar is
fed out.
By using different lubrication oil pumps, the amount of oil
supplied to the saw bar can be varied depending on
different lubrication requirements.
