CAB SET-UP FOR PUMP OPERATION
See Fire Pump Manufacturer’s Manual for more detailed information.
TO PLACE FIRE PUMP IN GEAR:
1. Truck must be stopped and parking brake set.
2. Truck transmission should be in "neutral" position.
3. Engine must be at idle R.P.M.
4. Move the pump shift lever from "road" position to "pump" position. Do this by pulling
back on the lever. At the same time the pump shift is activated, the lock-up for the
automatic transmission is also engaged. The pump shift lever holds the transmission in
the pumping gear position.
5. Shift transmission to Drive position. Power from the engine is now being transferred to
the pump drive gear and pump impellers are turning. Observe the illuminated green
indicator light next to the shift lever. If the light is not lit, the pump is not engaged, and
you need to repeat steps 1-5 and observe for pump engagement.
6. Leave transmission selector in "neutral" for the pump to be ready to operate without
churning. For pump operations, put transmission selector in Drive.
SET UP FOR SIMULTANEOUS TOWER AND PUMP OPERATIONS
1 Follow STEPS FOR PLACING PTO IN GEAR on page 9.
2 Follow AERIAL TOWER SET-UP instructions on page 12.
3 Leave transmission selector in "neutral" for the pump to be ready to operate without
churning.
4 Repeat steps 4 through 6 for placing pump in gear on this page.
When arriving at a structure fire or on occasion where the tower is not immediately needed,
but the fire pump is being used, place the PTO in gear and deploy the ground stabilizers
before placing the fire pump in gear. Then, if the need to use the tower arises while the fire
pump is being used, the stabilizers can be set and the tower will be ready for immediate use.
If the PTO is not engaged before the pump is set up, then slow the engine to idle before
engaging PTO.
