Komatsu — 3.3.1.5 STARTING ENGINE

MACHINE OPERATIONS AND CONTROLS 4. When the engine start, release the key in the starting switch (3). The key will return automatically to the ON po- sition. Starting Engine in Cold Weather Start the engine only after sitting down in the operator's seat. Do not attempt to start the engine by short-circuiting the engine starting circuit. Such an act may cause a serious bodily injury or fire. Check that there are no persons or obstacles in the surrounding area, then sound the horn and start the engine. Never use starting aid fluids as they may cause explosions. Exhaust gas is toxic. When starting the engine in confined spaces, be particularly careful to ensure good ventilation.

IMPORTANT Do not keep the starting motor rotating continuously for more than 20 seconds. If the engine does not start, wait for at least one minute, then repeat the operation from Step 3. When starting in low temperatures, do as follows. 1. Check the safety lock lever (1) is at the LOCK position (L). If the safety lock lever is in the FREE position (F), the en- gine does not start. NOTE For machines equipped with a cab, there is only a safety lock lever on the left. 2. Pull fuel control lever (2) fully from the low idling position (position A) to the full speed position (position B). 104 WARNING
