3.3 OPERATIONS AND CHECKS AFTER STARTING ENGINE
• When problems such as emergency stops or abnormal running occur, turn the starter switch
key to the OFF position.
• If you move the machine without sufficient warm-up, the response of the machine to the
operating levers may be slow, which may result in movements unintended by the operator, so
warm-up should always be performed. Make sure there is adequate warm-up time, especially
in cold conditions.
3.3.1 WARM-UP
CAUTION
• Do not perform work or make sudden lever operations while the hydraulic oil temperature is
still low. Do not fail to execute the engine warm-up. It also extends the life of the machine.
• Do not accelerate the engine suddenly until the warm-up operations are done.
Do not perform low idling or high idling under no load for more than 20 minutes. If the engine
requires (oil down) idling, occasionally apply a load to the engine, or run the engine at a
mid-speed idle.
After starting the engine, do not begin operation of the machine immediately, but perform the following
operations and checks.
1. Depress the accelerator pedal (4) to the intermediate
position between the low idling position and the full
rotation position, rotate the engine at medium speed, and
operate with no load for about 5 minutes.
NOTES
If the temperature is below 0 ºC, hold the accelerator
pedal at about 1/4 to warm up.
2. Place the lock lever (1) at the Free position (F).
