Operating Instructions - Section 30 OM3044 Page 30-10 DELAYED ENGINE SHUTDOWN PROCE- DURE NOTE: To cancel the 5 Minute Idle Timer sequence, press Timer Delay Shutdown switch to the OFF (lower) position. If keyswitch is in OFF position, engine will stop. If keyswitch is in ON position, engine will con- tinue to run. 1. Stop the truck out of the way of other traffic on a level surface and free of overhead power lines or other obstructions (in case dump body should need to be raised). a. Reduce engine speed to low idle. If engine does not shutdown with keyswitch, use Engine Shutdown Switch (8, Figure 32-5) on operator cab center console, and hold this switch down until engine stops.
The Ground Level Shutdown Switch will also stop the engine during this time-out. b. Place the directional Selector Switch (2, Figure 32-5) in NEUTRAL. c. Apply the Parking Brake switch (13, Figure 32-6). Be sure the “parking brake applied” indicator light in the overhead dis- play panel is illuminated. d. When the Engine Shutdown Timer has been activated, the Timer Delay indicator light in the overhead display panel (C4, Fig- ure 32-7) will illuminate to indicate that the shutdown timing sequence has been started. The engine will continue to run at Idle RPM for approximately 5 minutes to allow for proper engine cool-down before stopping. 2.
Refer to “Instrument Panel and Indicator Lights” for the location of the Engine Shut- down Switch with 5 Minute Idle Timer Delay (2, Figure 32-6). This is a 3-position rocker-type switch (OFF- ON-MOMENTARY). 3. After engine has stopped, perform steps 4 and 5, as described in “NORMAL ENGINE SHUTDOWN PROCEDURE” above. Press top of switch to the ON (center position), then press firmly to the MOMENTARY (upper position) and hold this position briefly to activate the 5 Minute Idle Timer (switch is spring-loaded to return to ON position when released). At the SAME time while holding the MOMENTARY switch position, turn the Keyswitch counterclock- wise to the OFF position.
When the engine stops after the 5 minute idle period, the hydraulic bleeddown timer will be activated and turn OFF the 24 VDC electric circuits controlled by the keyswitch. Engine WILL NOT SHUT DOWN, if keyswitch is not turned OFF in this manner.
