STOPPING THE ENGINE
1. After setting the engine throttle to “SLOW” , turn the
key switch to the “OFF” position.
2. Remove the key.
3. Do not leave the key switch at
“ON” (key in the
“ON” position), as the battery will discharge when
the engine is not running.
4. Apply the parking brake.
5. If stopping the machine for a long time. Turn the
fuel valve to the “STOP” (OFF) position.
(1) Fuel valve (A) “STOP” (OFF)
(B) “RUN”
IMPORTANT :
• Do not stop the engine when the machine is
on an incline for a long time. Should you
have to, immediately apply the parking
brake.
• Before stopping the engine, place the
throttle control dial to the half speed
position to help prevent the engine from
backfiring.
COLD WEATHER STARTING
If the ambient temperature is below 0
℃
(32
℉
) and the
engine is very cold, start it in the following manner:
1. Turn the key switch to the “START” position.
a. Operate the starter 5 seconds.
b. If the engine does not start, wait 15 seconds.
c. Repeat this procedure until the engine starts.
2. When the engine starts, release the key to the “ON”
position.
IMPORTANT :
• To protect the battery and the starter, make
sure not to turn the starter continuously for
more than 5 seconds.
• If it is difficult to start the engine, turn the
throttle dial slightly.
Engine stalling is likely to occur without
warming up.
In this case re-start engine while turning the
throttle dial approximately 1/4.
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
