GRT655/655L OPERATOR MANUAL OPERATING PROCEDURES
PRE-STARTING CHECKS
A complete walk-around visual inspection of the crane
should always be made with special attention to structural
damage, loose equipment, leaks, or other conditions that
would require immediate correction for safe operation. Refer
to Lubrication and Maintenance, page 6-1.
The following items are suggested to be checked to make
sure the crane is prepared for starting the day’s work.
Fuel Supply
Fill fuel tank and make sure cap is on tight.
Engine Oil
Check oil level in the crankcase and make sure it is within the
ADD and FULL marks on the dipstick. Do not overfill.
Engine Coolant
Check surge tank coolant level sight gauge and fill to the
proper level. Do not overfill. Make sure surge tank cap is
secure.
Batteries
Check battery cables and clamps are tight and not corroded.
Hydraulic Reservoir and Filter
Check hydraulic level sight gauge and filter condition
indicator on the hydraulic tank. Hydraulic fluid should be at
normal operating temperature, with boom and outriggers in a
retracted position, and boom level.
Check breather for cleanliness and make sure it is secure.
Hoist Rope
Inspect hoist rope in accordance with applicable Federal
Regulations. Sheaves, guards, guides, drums, flanges, and
any other surfaces that come in contact with the rope should
be inspected for any condition that could cause possible
damage to the rope.
Hook Block and Overhaul Ball
Inspect for nicks, gouges, cracks, and evidence of any other
damage. Replace a hook that has cracks or shows evidence
of excessive deformation of the hook opening (including
twist). Be sure safety latch is free and aligned.
Seats and Mirrors
Adjust seat and mirrors for clear vision and safe driving.
Seat Belts
Seat Belt Maintenance
Seat belt assemblies are maintenance-free; however, they
should be periodically inspected to make sure they are not
damaged and are in proper operating condition, especially if
they have been subjected to severe stress.
Cleaning Seat Belt Webbing
Wash seat belt webbing with mild soap or detergent. Do not
use commercial solvents. Bleaching or re-dyeing the
webbing is not recommended because of possible loss of
webbing strength.
Signal and Running Lights
Check all signal and running lights for proper operation.
Replace burned out lamps with those of the same number, or
equivalent.
Service and Parking Brakes
Check for proper operation.
Tires
Check for severe cuts, foreign objects embedded in treads,
and for correct inflation pressures. A tire inflation chart,
providing the correct air pressures, is located in the Load
Chart Manual in the crane cab.
Wheels
Maintain proper torque on wheel lugs and check for proper
wheel mounting. If equipped with steel or aluminum wheels,
re-torque wheels 300 hours after initial installation or any
time tires and wheels are removed. Doing this re-seats the
lug nuts. Check lug nuts for proper torque every 500 hours
thereafter.
Axle Oscillation Lock Outs Operation
The following procedure should be used to periodically
check the axle oscillation system and make sure it is in
proper working condition.
1. Make sure tires are inflated to recommended pressure.
Refer to Load Chart Book in the crane cab for proper
inflation pressures.
2. With hook unloaded, boom fully retracted and centered
over the front at no more than a 10° to 15° boom angle,
position crane on a block or curb so one rear tire is
CAUTION
Do not overfill.
DANGER
Do not loosen radiator cap while engine and radiator are
hot. Steam or hot coolant will cause severe burns.
