Inspection Guide
Cab Interior Inspection
1. Safety/Emergency Equipment: Prior to entering
cab, verify that vehicle is equipped with the proper
equipment. Walk around vehicle and check that all
steps and grab handles, inside and out, as well as
behind, are tight and clean. Use extreme caution and
maintain 3 point contact at all times.
2. Doors: Check door latches for positive closing, latching
and locking.
3. Clutch/Gearshift: Depress clutch pedal (if present ) and
verify transmission is in neutral before turning on starter;
keep depressed until engine reaches idling speed and
vehicle in neutral.
4. Oil Pressure Builds: Check to see that oil pressure is
building to a normal level. Engine oil pressure gauge
should begin a gradual rise to normal operating range.
5. Low Air Alarm: The low air pressure alarm may sound
immediately after the engine starts but before the air
compressor has built up minimum 55 psi pressure.
The low air pressure alarm should stop when the air
pressure reaches 60 to 76 psi (414 to 524 kPa). Let the
air pressure build to governor cut-out pressure, which
should occur between 115 and 130 psi (793 and 896
kPa).
6. Accelerator: Depress accelerator pedal and verify that it
operates smoothly without any binding or irregular feel.
Remove foot from accelerator and make sure engine
returns to idle immediately.
7. Voltmeter: Check the gauge to see if the alternator is
charging between 12.5 and 14.5 volts.
8. Steering Play: Check for smooth operation. Check
for excessive looseness in the steering linkages. The
steering wheel should have less than 10 degrees free
play (approximately 2 inches at rim of 18 inch steering
wheel).
9. Seats: Be sure seats are firmly engaged to avoid
forward or rearward movement when starting or
stopping. Make sure that seats and tether straps
arefreefromdamageandsecuredtofloor.
10. Horn(s): Check to see that horn(s) operate properly.
11. Mirrors: Check mirrors for proper adjustment, damage,
cleanliness, and proper mounting. Check (optional)
power mirrors and (optional) heated mirrors for proper
operation.
12. Doors: Ensure windows are clean and operate properly
and smoothly in both doors.
13. Windshield and Wipers: Check windshield for cracks,
dirt, illegal stickers or other obstructions to view. Ensure
wipers and windshield washer are functioning properly.
14. Lighting Indicators: Check to see that dash indicators
illuminate when corresponding lights are turned on.
15. Heater/Defroster: Check to be sure that heater/defroster
is working. Verify adequate air flow from louvers and
vents. Operate Temperature and Mode controls to verify
proper operation.
