Mirrors, Windows, And Lights

• Remove any dirt from the surface of the

windshield, cab windows, mirrors, and lights.

Good visibility may prevent an accident.

  • Adjust the mirrors to a position where the

operator can see best from the operator's seat. 

  • Ensure the headlights, work lights, tail and stop

lights (1, Figure 3-1), turn signal and clearance

lights (2), and backup lights (3) are in proper

working order. Ensure that the machine is

equipped with the proper work lamps needed for

the operating conditions. Verify backup alarms

  • Replace any broken mirrors, windows, or lights.

In The Operator’s Cab - Before Starting The 
Engine

  • DO NOT leave tools or spare parts lying around

or allow trash to accumulate in the cab of the

truck. Keep all unauthorized reading material out

of the truck cab.

  • Keep the cab floor, controls, steps, and handrails

free of oil, grease, snow, and excess dirt.

• Read and understand the contents of the

Operation and Maintenance manual. Read the

safety and operating instructions with special

attention. Become thoroughly acquainted with all

the gauges, instruments, and controls before

operating the truck.

  • Read and understand the warning and caution

decals in the operator's cab.

  • Ensure the steering wheel, horn, controls, and

controls, warning devices, road speeds, and

loading capabilities before operating the truck.

Seat Belts

  • On both driver and passenger seats, check the

seat belt fabric, buckle, all belt retractors and

hardware for damage or wear. Replace any worn

or damaged parts immediately.

  • Even if there are no signs of damage, replace

both driver and passenger seat belts 5 years after

seat belt manufacture, or every 3 years after start

of use, whichever comes first. The passenger

seat belt date of manufacture label is sewn into

the seat belt near the buckle. The driver seat belt

date of manufacture label is sewn into the back of

the seat belt.

around the truck.
