IMPORTANT: Avoid starter damage.

●Do not hold the key in the START position for more than 15 seconds at a time. Any longer attempt will overheat the starter motor.

●If the engine is difficult to start at a low temperature etc., hold the key in the START position for 30 seconds. If the engine fails to start, wait at least 30 seconds before the second attempt to allow for battery voltage recovery.

●If the engine still fails to start with four consecutive attempts, the starter may be not functioning. (See “17. TROUBLESHOOTING” ).

13.After the engine has started, warm up

the engine for 5 minutes at 2000 to 2400 rpm without loading.

■Warming Up the Engine in Cold Weather

In cold weather, warm up the engine for much longer than 5 minutes so that the hydraulic system shows its performance. For the appropriate warming up time, refer to the table below.

Temperature (°F (°C))	Warming-up Time (min.)
Over 32 (0)	At least 5
32 to 14 (0 to –10)	5 to 10
14 to –4 (–10 to –20)	10 to 15
Below –4 (–20)	More than 15

NOTE:

●The engine may run slightly louder and emit pale blue exhaust during warming-up. This is considered normal operation. The amount of pale blue exhaust varies depending on the ambient temperature.

●Idling the engine for a long time causes waste of fuel and carbon accumulation in the engine.
