Operation - Section 3 OM3037 Page 3-10 Operating Instructions DELAYED ENGINE SHUTDOWN PROCEDURE 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 3-5) 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, Fig- ure 3-5) in “ N eutral”. c. Apply the Parking Brake switch (13, Figure 3-6). Be sure the “parking brake applied” indicator light in the overhead dis- play panel is illuminated. b. When the Engine Shutdown Timer has been activated, the Timer Delay indicator light in the overhead display panel (C4, Figure 3-7) will illumi- nate 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 3-6). This is a 3-position rocker-type switch (Off-On- Momentary). a. Press top of switch to the “On” (center posi- tion), 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 counterclockwise 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 cir- cuits controlled by the keyswitch. 3. After engine has stopped, perform steps 4 and 5, as described in “NORMAL ENGINE SHUTDOWN PROCEDURE” above. Engine WILL NOT SHUT DOWN, if keyswitch is not turned “Off” in this manner.
