8. Move behind the front wheel and inspect the
steering cylinder. Check for proper greasing
and inspect the mounting hardware to ensure it
is all in place. Inspect the suspension mounting
hardware to ensure it is all in place. Ensure the
suspension protective boot is in good condition.
Inspect the hub and brakes for any unusual
conditions. Check the entire area for leaks.
9. Inspect the sight glass on the hydraulic tank.
With the engine stopped and body down,
hydraulic fluid must be visible in the upper sight
glass.
10. Verify all hydraulic tank shut off valves are
locked in their fully open positions.
11. Move around the hydraulic tank and in front of
the rear dual tires. Inspect the hoist cylinder for
any damage and leaks. Inspect both upper and
lower hoist cylinder pins for integrity and for
proper greasing.
12. Before leaving this position, look under the
lower edge of the chassis to ensure the flexible
duct that carries the air from the blower to the
final drive housing is in good condition with no
holes or breakage. Also, look up at the main
hydraulic pumps to see that there is no leakage
or any other unusual condition with the pumps
or the pump drive shafts.
13. Move around the dual tires, and check to see
that all lugs/wedges are in place and tight.
Inspect latches on the wheel cover to be sure
they are properly latched. Inspect the wheel for
any oil that would indicate brake leakage or
wheel motor leakage.
Check the dual tires for cuts, damage or bub-
bles. Verify that inflation appears to be correct.
If the truck has operating on a flat tire, the tire
must be cool before moving the truck inside a
building. Check for any rocks that might be
lodged between the dual tires. Inspect the rock
ejector condition and straightness so that it can
not damage a tire.
14. Inspect the left rear suspension for damage and
for correct rod extension. Check for leaks.
Ensure that the covers over the chrome piston
rod are in good condition. Inspect for proper
greasing.
15. Open the rear hatch cover, turn on work light, if
necessary. Inspect for leaks around wheel
motor mounting to rear housing, and also brake
hoses and fittings. ensure that covers on wheel
motor sump are in place, and that there are no
rags or tools left behind. Inspect condition of
hatch cover gasket, report any bad gasket to
maintenance. Turn off work light if used, close
and latch hatch.
16. While standing in front of the rear hatch, look up
to see that rear lights are in good condition,
along with the back-up horns. Look up at the
panhard rod to see that it is getting proper
greasing. Also look at both body hinge pins for
greasing and any abnormal condition. Check
hoist limit switch and clear any mud/debris from
contacts.
17. Perform the same inspection on the right rear
suspension as done on the left.
18. Move around the right dual tires. Inspect
between the tires for rocks, and check the con-
dition of the rock ejector. Inspect the tires for
cuts or damage, and for correct inflation.
19. Perform the same inspection for wheel lugs/
wedges, wheel cover latches, and wheel leaks
that was done on the left hand dual wheels.
20. Move in front of the right dual tires and inspect
the hoist cylinder in the same manner as the left
side. Check integrity and condition of the body-
up limit switch. Remove any mud/dirt accumula-
tion from the switch.
21. Move around the fuel tank. Inspect the fuel sight
gauge, (this should agree with what will show
on the gauge in the cab). Inspect the attaching
hardware for the fuel tank at the upper saddles,
and then at the lower back of the tank for the
security and condition of the mounts. Check the
hoist filters for leaks.
22. Move behind the right front wheel, and inspect
the steering cylinder. Check for proper greasing
and inspect the mounting hardware. Check the
suspension mounting hardware and suspension
extension. Ensure the suspension protective
boot is in good condition. Inspect the hub and
brakes for any unusual conditions. Check the
entire area for leaks.
