Idle 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 coolant temperature reaches a normal operating temperature.
Machine Warm-up
1. Start the engine.
2. Adjust the throttle to run the engine unloaded at low
idle for about 5 minutes.
3. Place the hydraulic lockout control lever in the
unlocked (open) position.
4. Adjust the throttle to run the engine unloaded at 1400
rpm, then slowly operate the bucket for 5 minutes.
5. Adjust the throttle to run the engine at high idle, then
operate the boom, arm, and bucket for 5–10 minutes.
6. Cycle each function of the machine several times.
7. Continue to warm up the machine until the engine
coolant temperature reaches the normal operating range
displayed on the monitor.
8. Press function button F1 (2) to select the desired work
mode. The mode will be displayed in the icon (1) on the
monitor.
NOTICE!
Do not over-rev the engine during the warm-up
period. Operating the engine beyond its design
levels could cause damage to the machine.
