OPERATING CONTROLS AND PROCEDURES
CAUTION
Machine Damage Hazard!
Do not travel with an empty hook in a position where it can
swing freely (except where noted). Either remove the
hook block and/or headache ball from the hoist cable(s)
and stow securely or make sure the hook block or
headache ball is properly secured to the tie down
provided for that purpose.
Do not drive the crane with the lift cylinder bottomed. At a
minimum, position the boom slightly above horizontal.
Fully retract the outrigger stabilizers and properly store
the floats.
Disengage Main Hydraulic Pump via pump disconnect for
cold weather starting of the engine (Sub-Zero). Pump
must be re-engaged for travel.
CAUTION
Machine Damage Hazard!
Grove recommends towing or pulling another vehicle with
the optional pintle hook (if equipped) or by attaching at a
point no higher than the pintle hook height, or severe
damage may occur to the drivetrain.
Do not tow or pull by attaching to the tie-down lugs unless
the attaching point is no higher than the pintle hook
height.
Use four-wheel drive when greater traction is necessary
to avoid severe damage to the drivetrain.
Should the crane become mired down, use a tow truck or
tractor to free the vehicle. Severe damage to the
drivetrain may occur if the operator attempts to free the
crane unassisted.
• Use four-wheel drive only when greater traction is
necessary. (Refer to Four-Wheel Drive Operation, page
3-26 for operating instructions.)
• Ensure the outrigger beams and stabilizers are fully
retracted with the floats properly stowed.
• Conduct all travel with the assistance of a ground person
to warn the operator of any changing conditions in the
terrain being traversed.
The owner/lessee must take appropriate measures to
ensure that all persons operating or working with the affected
models are in compliance with The Manitowoc Company,
Inc. recommendations. The operator of the crane assumes
responsibility for determining the suitability of traveling
3-22
conditions. Traveling under the controlled conditions
specified in these guidelines, must be conducted with the
utmost diligence and care to ensure the safety of all
personnel performing the operation and/or working around
the crane.
