OPERATION OPERATION
3-69
STARTING IN COLD WEATHER
After starting the engine, do not immediately start operations.
First, carry out the following operations and checks.
NOTICE
Avoid abrupt acceleration until warm-up run is completed.
Do not run the engine at low idling or high idling for more
than 20 minutes. If it is necessary to run the engine at
idling, apply a load or run at a medium speed from time to
time.
1. Pull fuel control lever (1) to a position midway between
the low idling and full speed positions, run the engine at a
mid-range speed, and continue to run under no load for
approx. 10 minutes.
2. Operate blade control lever (3) fully to the RAISE posi-
tion, then hold the lever in position, and operate slowly to
the left tilt relief and right tilt relief in turn for 5 minutes.
3. After this, operate the blade control lever (3) fully to the
RAISE position, hold the lever in position, and relieve the
left and right tilt intermittently. Next, operate the lever to
the LOWER position and lower the blade to the ground,
then operate the lever fully to the FLOAT position, hold
the lever in position, and relieve the left and right tilt in
turn intermittently for 5 minutes.
4. Lower the blade to the ground, operate the control lever fully to the FLOAT position (lever stroke end) and
hold the lever in position by hand for 1 minute. Next, release the lever and check that it is held at the FLOAT
position. After waiting for 3 minutes, return the lever to the HOLD position.
REMARK
If the work equipment oil is not up to operating temperature, the response of the work equipment or steering may
be slow, the lever may become heavy or may not return properly. Also, if the blade control lever is set to the
FLOAT position and released immediately, the lever may return to the HOLD position.
