COLD WEATHER STARTING
If the ambient temperature is below 0
℃
(32
℉
) and the
engine is very cold, start it in the following manner:
1. Place the throttle lever to the “CHOKE” position.
2. Place the throttle lever midway between the
“SLOW” and the “FAST” positions.
3. Turn the key switch to the “START” position.
a. Operate the starter 5 seconds.
b. If the engine does not start, wait 10 seconds.
c. Repeat this procedure until the engine starts.
4. When the engine starts, release the key to the “ON”
position.
WARMING UP THE ENGINE
WARNING
To avoid serious injury or death:
• Be sure to apply the parking brake during
warm-up.
For 5 minutes after the engine start-up, allow the
engine to warm up without applying any load. This is to
allow oil to reach every part of the engine. If load is
applied to the engine without this warm-up period,
problems such as seizure, breakage or premature wear
may appear.
1. Warm-up and transmission oil in
the low temperature range
Hydraulic oil serves as transmission oil. In cold weather
conditions, the oil may be cold with increased viscosity.
This can cause delayed oil circulation or abnormally
low hydraulic pressure for some time after engine start-
up. This, in turn, can create problems with the hydraulic
system.
To prevent this from happening warm up the engine at
about 50% of rated rpm according to the following
table.
Ambient temperature Warm-up time requirement
Higher than 0
℃
(32
℉
) Approximately 5 minutes
-10 to 0
℃
(14 to 32
℉
) 5 to 10 minutes
-20 to -10
℃
(-4 to 14
℉
) 10 to 15 minutes
Below -20 ℃ (-4 ℉ ) More than 15 minutes
IMPORTANT :
• Do not operate unless the engine is well
warmed up. If operation is attempted while the
engine is still cold, the hydraulic mechanism
will not function properly and its service life will
be shortened.
JUMP STARTING
WARNING
To avoid serious injury or death:
• Keep cigarettes, sparks, and flames away from
the battery.
• If the machine battery is frozen, do not jump
start the engine.
• Do not connect the other end of the negative
jumper cable to the negative terminal of the
machine battery.
When jump starting the engine, observe the following
instructions to start the engine safely:
1. Bring a helper vehicle with a battery of the same
voltage as the disabled machine within easy cable
reach.
IMPORTANT :
• The vehicles must not touch.
2. Apply the parking brakes of both vehicles and put
the shift levers in the neutral position. Shut the
engine off.
3. Put on safety goggles and rubber gloves.
4. Ensure that vent caps are securely in place (if
equipped).
5. Attach the red clamp to the positive (red, (+) or
pos.) terminal of the dead battery and clamp the
other end of the same cable to the positive (red, (+)
or pos.) terminal of the helper battery.
6. Clamp the other cable to the negative (black, (-) or
neg.) terminal of the helper battery.
