GRT9165 OPERATOR MANUAL OPERATING PROCEDURES
1. Make sure tires are inflated to recommended pressure.
Refer to Load Chart Manual in the crane cab for proper
inflation pressures.
2. Program the RCL with a travel rigging code based on the
configuration of the crane:
- 9816 – On Rubber, Boom Centered Over Front,
without Counterweight
- 9014 – On Rubber, Boom Centered Over Rear, with
Standard Counterweight
- 9016 – On Rubber, Boom Centered Over Front, with
Standard Counterweight
3. Set the suspension to the Ride Height level (refer to
Suspension Raise/Lower, page 4-107).
4. Center the rear wheels.
5. With hook unloaded, boom fully retracted and centered
over the front or rear at no more than a 10° to 15° boom
angle, position the two left or right side rear tires on
blocks so that the rear tires are approximately 15 to
30 cm (6 to 12 in) above the level of the opposite tires.
6. Slowly swing the superstructure at least 2° to left or right
of center to activate the axle oscillation lock out valve.
Refer to the Suspension Control Indicator
(5, Figure 4-78) to confirm the suspension is locked. Do
not swing beyond tire track.
7. Slowly drive off of blocks and stop. Rear tires should be
touching the road surface and the opposite front tire
should be light or slightly off road surface.
8. Swing superstructure until it is centered over the crane
again. If axle oscillation lock out valve is functioning
properly, crane will re-level itself; if valve is not working
properly, crane will not re-level itself.
If rear axles do not lock or unlock properly, do not
operate the crane until the lock out system has been
evaluated and repaired as necessary.
Safety Equipment
Check all lights, windshield wipers, washers, washer liquid
supply, horn, instruments, signaling devices, etc.
Daily Lubrication
Make sure all components requiring daily lubrication have
been serviced. Refer to Maintenance and Lubrication, page
6-1.
Boom
Before extending boom, make sure access covers on top of
boom base section and on face of boom nose are installed.
Air Intake Restriction Monitoring (AIRM)
Communications System
The engine includes the Cummins AIRM Communications
System. This system calculates real-time air filter restriction
at operational flow rate using the temperature and pressure
input from the TBAP sensor, which is included on the Direct
Flow air cleaner.
When the air filter becomes dirty and should be replaced, a
maintenance fault is generated and the Engine Warning
Indicator in the Alerts Area (1, Figure 4-74) of the Operator
Display Module (ODM) flashes for a period of time at every
key on. Replace the air filter at the next maintenance
interval.
If the air filter becomes more dirty, a severe warning fault is
generated and the Engine Warning Indicator comes on
(constant). A progressive engine derate will occur to protect
the engine from damage.
The generated fault codes can be viewed on the Operator
Display Module (ODM) (refer to Engine Faults, page 4-145).
COLD WEATHER OPERATION
The following recommendations are for operating Grove
cranes in regions with ambient temperatures below -9°C
(15°F) which are considered arctic.
NOTE: Additional information regarding engine cold
weather operation is available through your
Cummins dealer/service center under Service
Bulletin 3379009.
Use particular care to make sure cranes operated in very
cold temperatures are operated and maintained in
accordance with procedures provided by Grove. Always
make sure there is adequate lubrication during system
warm-up. Regardless of crane lubricant viscosity, always
follow cold weather warm-up procedures described in the
section Crane Warm-up Procedures, page 4-11. For proper
cold weather lubricants, refer to the section Arctic Lubricants
and Conditions, page 6-5.
If in doubt of suitability for a specific fluid or lubricant, check
with an authorized Grove distributor or Manitowoc Crane
Care. Cranes should have appropriate hydraulic oil,
lubricants, and other auxiliary items required for operation in
arctic temperatures.
DANGER
Tipping Hazard!
Do not operate crane if axle oscillation lock out system is
not functioning properly.
Failure to comply with this warning may result in death or
serious injury.
