Cold Weather Warm-Up - Worldwide Construction And Forestry Division 380GLC Operator's Manual

Cold Weather Warm-Up

CAUTION: Prevent possible injury from
unexpected machine movement. If hydraulic oil
is cold, hydraulic functions move slowly. DO NOT
attempt normal machine operation until hydraulic
functions move at close-to-normal cycle times.
IMPORTANT: Prevent possible damage to the engine.
The diesel fired coolant heater is required for
temperatures -20°C (-4°F), and below. See
an authorized John Deere dealer.
IMPORTANT: Prevent possible damage to engine.
Temperatures below -20°C (-4°F) require a diesel
fired coolant heater warm-up period. At -20°C
(-4°F), the engine requires 1-hour warm-up
period. Temperatures below -20°C (-4°F) require
additional warm-up period. See table below.

In extremely cold conditions, an extended warm-up period
is necessary.
Avoid sudden operation of all functions until the engine
and hydraulic oil are thoroughly warm.

1. If temperature is below 0°C (32°F), engine will start
at 800 rpm and ramp to 1200 rpm after 30 seconds.
Engine maintains 1200 rpm until hydraulic temperature
reaches 2°C (35.6°F) or 15 minutes have elapsed,
whichever comes first.
2. Run engine at 1/2 speed for 5 minutes. Do not run
at fast or slow idle.
CAUTION: Prevent possible injury from
unexpected machine movement. Clear the area
of all bystanders before running machine through
the warm-up procedure. If machine is inside a
building, warm the travel circuit first and move
the machine to a clear area outside. Cold oil
causes machine functions to respond slowly.
3. Actuate travel and swing functions slowly, initially
moving only short distances.
4. Operate boom, arm, and bucket functions by moving
cylinders a short distance in each direction for the
first time.
5. Continue cycling cylinders by increasing travel each
cycle until full stroke is obtained.
6. Swing upperstructure so boom is perpendicular to
tracks.
CAUTION: Prevent possible injury from machine
sliding backwards. Keep angle between
boom and arm 90—110°.
7. Keeping the angle between boom and arm 90—110°,
fully actuate bucket close function (cylinder extend)
and lower bucket to raise track off ground.
IMPORTANT: Holding function actuated for more
than 10 seconds can cause damage from
hot spots in the control valve.
8. While rotating raised track in forward direction, actuate
bucket curl function (cylinder extend) for 10 seconds
and release for 5 seconds for a period of 2-1/2 minutes.
9. Repeat procedure with track rotating in reverse
direction.
10. Lower machine to ground.
11. Repeat steps 6—10 on opposite track.
12. Operate all hydraulic functions to distribute warm oil
in all cylinders, motors, and lines.
13. If hydraulic functions still move slowly, repeat steps
7 and 8.
