Warm-up Operation
Perform the following warm-up procedures:
1. Deactivate the auto idle mode after starting the engine and adjust the throttle so the engine runs unloaded at
1250 rpm for 5 minutes.
2. Adjust the throttle so the engine runs at 1400 rpm, then slowly operate the bucket for 5 minutes.
3. Adjust the throttle so the engine runs at maximum rpm, then operate the boom, arm, and bucket for 5 to 10
minutes.
4. Repeat all movements several times and stop the warm-up process. Check the gauges and indicators for normal
operating readings after the warm-up process.
Idling the Engine
Idling the engine for long periods wastes fuel and causes carbon formation, oil dilution, formation of lacquer or
gummy deposits on the valves, pistons, and rings, and rapid accumulation of sludge in the engine.
Allow the engine to idle until the engine temperature reaches 140°F (60°C) before beginning operation.
WARNING!
• In case of emergency, irregular engine operation, or other faults, turn the key switch to OFF
to stop the engine.
• Insufficient warm-up of the machine may cause slow response or abrupt movement during
operation, resulting in serious accidents. Warm-up is especially necessary in cold areas.
• Operating the machine before the hydraulic oil is warmed to operating temperature may
cause slow control response or abrupt movement during operation.
Failure to follow these warnings could result in death or serious injury.
NOTICE!
• Never operate the machine immediately after starting the engine.
• Allow the engine to warm to 140°F (60°C), and the hydraulic oil to warm to 104°F (40°C),
before beginning operations.
