Operational Safety
• Check the grapple for damages at the beginning
of each shift. Tighten all fasteners regularly.
• Make sure that the hydraulic pressure in the
grapple cylinder is adjusted according to the
specifications. If the pressure is too low the
grapple will not be able to carry its load. If the
pressure is too high, the grapple will be
overloaded, which could cause a structural
failure, resulting in injury and/or property
damage.
• The grapple must not be used for lifting
personnel.
• The grapple is not designed for handling rocks,
heavy spare parts, etc.
• The grapple arms on the SuperGrip II-A must
NOT be used to dig up stumps and rocks.
If used as described above the grapple arms or other
parts of the grapple could fail, resulting in injury and/
or property damage.
• The load of the grapple must not exceed the
recommended maximum rating as structural
failure could occur, resulting in injury and/or
property damage.
• When operating this equipment ensure all
unauthorized persons remain at least 15 meters
clear of the machine.
• The operator must immediately evict
unauthorized persons who are in the danger zone
or are heading towards the danger zone
• Personnel inside the danger zone must be well
protected against falling load.
• Personnel inside the danger zone must keep clear
of hanging load.
• The operator should be aware that the load, or
parts of the load, could fall from the grapple at
any time.

Maintenance safety
• The machine's condition must be checked
regularly, daily inspections shall be performed
and any deficiencies must be corrected. The
machine shall be maintained in such condition
that the operator or other persons not exposed to
danger or accidents.
• Never commit any service on the equipment
without proper knowledge. All service and
repairs in electrical and hydaulical systems
should be carried out by qualified personnel only.
• Repair any damages immediate when discovered.
Do not use the equipment until any damages are
rectified.
• Before performing any maintenance or service
work, lower the grapple to the ground and shut
off the engine. Turn off any master shut-offs and
do not allow personnel in the cab.
• Use safety glasses and protective gloves when
servicing the equipment. Hydraulic oil or
lubricants in contact with skin or eyes may cause
irritations or allergies.
• Use hard hat and safety boots when servicing the
equipment. Leakage of hydraulic oil or lubricants
will increase the risk of slipping or falling.
• The grapple has sharp edges. Use proper
wrenches and protective gloves when working on
the grapple
• Hydraulic hoses and adapters may be pressurized
even with the engine shut off. Loosen any parts
with caution.
• Always make sure that the system is
depressurized before committing any service on
the equipment.
• Always secure movable parts mechanically
before any hydraulic hose is loosened.
• Never try to stop a leakage in the hydraulic
system with you hand. Pressurized hydraulic oil
can be injected under the skin and cause death or
severe damage.
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 grapple 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 closeto the welding area
as possible.
• When welding close to bushings, dissassemble
the bushings asthey are made of a plastic
compound-material which high temperatures may
damage.
Modifying the equipment
It is not approved to:
• Modify the grapple without the consent of
HULTDIN SYSTEM AB.
• Alter the function of the grapple without the
consent of HULTDIN SYSTEM AB.
• Use spare parts other than original HULTDINS
parts.
