less than one RPM for at least one complete revolution
in the opposite direction.
Warm-up Procedures for Temperatures Below -7°C
(20°F):
1. Ensure the boom is fully retracted and near maximum lift
angle with no load applied.
2. Rotate the superstructure at a speed of less than one-
half RPM for at least two complete revolutions in one
direction, then rotate the superstructure at a speed of
less than one-half RPM for at least two complete
revolutions in the opposite direction.

Axles

Warm-up Procedures for Temperatures Below -35°C
(-30°F):
1. Setup the crane on outriggers.
2. Engage the transmission (see Transmission, page 3-18)
with 4-wheel drive selected (if equipped) and allow
crane to run at idle until the temperature of the
transmission sump
temperature.
NOTE: Warm-up operation of 4-wheel drive transmission
engaged in 2-wheel drive only could cause
transmission damage.

Hydraulic Oil System

Operating Limits and Warm-up Procedures:
• From 4°C to -10°C (40°F to 15°F): Crane operation
without a load is allowed with medium engine RPM and
medium function speed (joystick position) until the fluid
reaches at least 10°C (50°F). It is then recommended
that all crane functions be cycled to remove cold fluid
from all components and cylinders of the hydraulic
system. If there is any unusual sound coming from the
crane's hydraulic pumps or motors, stop the operation
and engine immediately and contact a Grove distributor.
• From 10°C to 4°C (50°F to 40°F): Crane operation with
a load is allowed with medium engine RPM and medium
function speed (joystick position) until the fluid reaches
at least 10°C (50°F).
• From 95°C to 10°C (200°F to 50°F): Crane operation
with a load is allowed with no restrictions.
Above 95°C (200°F): No crane operation is allowed. Let the
crane's hydraulic oil cool by running the engine at idle with no
functions actuated.

OPERATING CONTROLS AND PROCEDURES

Engine Operation

Starting and shutdown procedures for most diesel engines
generally follow the same pattern. Therefore, the following
procedures can be applied except where specific differences
are noted. (Refer to the applicable engine manufacturers
manual for detailed procedures.)
Starting Procedure
Make an under-the-hood inspection for fuel, oil, and coolant
leaks, worn drive belts, and trash build-up
Health Hazard!
Diesel engine exhaust can be harmful to your health. Only
operate the engine in a well ventilated area or vent
exhaust outside.
Unexpected Operation Hazard!
Before starting the engine, apply the parking brake and
engage the swing lock.
CAUTION
Machine Damage Hazard!
Never crank the engine for more than 30 seconds during
an attempted start. If the engine fails to start after 30
seconds, stop and allow the starter motor to cool for
approximately two minutes before attempting another
start.
If the engine fails to start after four attempts, correct the
malfunction before attempting further starts.
Use the correct grade of oil for the prevailing temperature in
the crankcase to prevent hard cranking. Diesel fuel should
have a cloud point of 6°C (10°F) less than the lowest
expected temperature. In case of emergency, white
kerosene may be added to the fuel to bring the cloud point
down to the required temperature.This will minimize clogging
of filters and small passages by wax crystals. The addition of
kerosene is NOT recommended for general use.
Battery Disconnect Switch
Ensure Battery Disconnect Switch handle (1) (Figure 3-4) is
in the ON position (handle shown in the OFF position).
