24. As you move in front of the radiator, inspect for any debris that might be stuck in front of the radiator and
remove it. Check for any coolant leaks. Inspect all head and fog lights.
25. Before climbing ladder to first level, be sure ground level engine shutdown switch is "ON". Inspect fire control
actuator to be sure safety pin is in place and plastic tie that prevents accidental actuation is in place and in
good condition. Be sure battery disconnect switches are "ON".
26. Climb ladder to main deck. Always use grab rails and ladder when mounting or dismounting from the truck.
Clean ladder and hand rails of any foreign material, such as ice, snow, oil or mud.
27. When checking coolant in radiator, use coolant level sight gauge (if equipped) or observe coolant level through
opening in end of hood. If it is necessary to remove radiator cap, shut down engine (if running), and relieve
coolant pressure SLOWLY before removing radiator cap.
28. Inspect covers over braking grids to be sure latches are in place and secure. Inspect main air inlet to be sure it
is clear. Be sure all cabinet door latches are secure.
29. Move on around the cab to the back, open the doors to the brake cabinet, inspect for leaks. Before latching
doors, turn work lights off, if used.
30. Clean cab windows and mirrors; clean out cab floor as necessary. Insure steering wheel, controls and pedals
are free of any oil, grease or mud.
31. Stow personal gear in cab so that it does not interfere with any operation of the truck. Dirt or trash buildup,
specifically in the operator's cab, should be cleared. Do not carry tools or supplies in cab of truck or on the
deck.
32. Adjust seat and steering wheel so that it is comfortable for use.
33. Read and understand the OPERATOR CONTROLS AND INSTRUMENT PANEL discussion in this section. Be
familiar with all control locations and functions BEFORE operating truck.
1. Insure all personnel are clear of truck before starting engine. Always sound the horn as a warning before actu-
ating any operational controls. If the truck is in an enclosure, insure adequate ventilation before start-up.
Exhaust fumes are dangerous!
2. Be sure parking brake switch is in "On" position. Check and insure Selector Switch is in "Neutral" before start-
ing.
3. If truck is equipped with auxiliary cold weather heater system(s), do not attempt to start engine while heaters
are in operation. Damage to coolant heaters will result.
Always mount and dismount ladders facing the truck. Never attempt to
mount or dismount while the truck is in motion.
If engine has been running, allow coolant to cool, before removing the fill
cap or draining radiator. Serious burns may result if coolant is not allowed
to cool.
