If equipped, inspect the fire control actuator. Ensure that the safety pin is in place and the plastic tie that prevents accidental actuation is in place and in good condition. Ensure that the battery disconnect switches are activated. 33. Check the coolant level in the inverter cabinet radiator. The coolant level must be visible at the halfway mark in the upper sight gauge. 34. Move around to the rear of the cab. Open the doors of the brake cabinet and check inside the cabinet for leaks. 35.
Clean the cab windows and mirrors. Clean out the cab floor, if necessary. Ensure that the steering wheel, operator controls, and pedals are free of any grease or mud. 36. Stow any personal gear in the 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 the cab or on the deck. Always mount and dismount ladders facing the truck. Never attempt to mount or dismount while the truck is in motion. 30. Always use handrails and ladders when mounting or dismounting the truck. Clean any foreign material such as ice, snow, oil or mud from the ladders and handrails. 37.
Adjust the seat and the steering wheel for the operator’s comfort. 38. Before operating the truck, read about and understand the locations and functions of all operator controls listed in Section 32, Operator Cab And Controls. If the engine has been running, allow the coolant to cool before removing the fill cap or draining the radiator. Serious burns may result if skin comes in contact with hot coolant. 31. Use the coolant level sight gauge to check the coolant level in the radiator. If it is necessary to remove the radiator cap, ensure the engine is shut down and relieve coolant pressure by slowly removing the radiator cap. 32. Inspect the retarding grid and covers.
Ensure that the latches are in place and secure. Inspect the main air inlet to be sure it is clear. Ensure that all cabinet door latches are secure.
