Komatsu — 3.15 STOPPING THE ENGINES

OPERATION 3.15 STOPPING THE ENGINES Never stop the engines from full load except in case of emer- gency. Before shutting down run the engines at idling speed for approximately 5 minutes. This cooling down period prevents heat accumulation and thermal stress, especially in the tur- bochargers. For EMERGENCY SHUTDOWN of the Engine, use STRIKE BUTTON (12). Additional emergency shut-down switches are located on the power house. For more information See "POWER HOUSE" on page 184. Stopping procedure, see illustration Z 21758. 1. Park the Shovel at a safe place on level and solid ground. For more information See "PARKING THE SHOVEL" on page 239. 2.

Deposit the working attachment onto the ground, proceed as follows: A - Backhoe Attachment Lower the backhoe attachment fully extended onto the ground. The bucket opening must point to the ground. B - Bottom Dump Bucket Attachment Lower the bottom dump bucket attachment onto the ground with the stick in a vertical position below the boom-stick pivots. The bucket must rest completely flat on the ground. The positions A or B are necessary to prevent unintentional movement of the working attachment when the pressure in the hydraulic system is relieved. 3. Move all controls into neutral position. 4. Set toggle switch (4) to low idle speed position.

Let the engines idle for about five minutes without load. 5. Turn switches (7 and 10) clockwise to stop position. After the engines have come to standstill, relieve the pressure in the hydraulic system. 241 CAUTION CAUTION
