Maintenance Procedures Every 250 Hours or Every 6 Weeks
CASTER LUBRICATION
CAUTION
Use only the recommended lubricants for your ap-
plication. Refer to Capacities and Specifications
8000SRM1703 for lubrication specifications for
your lift truck.
Wipe grease fittings clean before greasing.
NOTE:
Some optional packages may utilize sealed
bearings or different grease fitting configurations.
Contact your Hyster dealer for information on op-
tional packages.
The casters should be lubricated every 250 hours or
6 weeks during normal operation. The caster as-
sembly has one grease fitting in the top plate to lu-
bricate the swivel bearing. See Figure 12.

CASTERS
Caster Adjustment Check
NOTE:
For trucks with 160” long forks, the height
difference should be 7 to 9 mm (0.270 to 0.350 in.),
measured on a level floor
As the drive tire wears, the caster should be period-
ically adjusted to maintain weight on the drive tire.
The time period will vary depending on the applica-
tion. Excess rocking is often a sign of under adjus-
ted casters. This may occur when a new drive tire is
installed. Loss of traction may be caused by over
adjusted casters. This may occur when the drive
tire diameter has decreased because of regular
wear. The casters should ideally be preloaded
7 mm (0.270 in.) from the unloaded condition.
1.
Select a smooth and level surface where the ad-
justment can be checked.
2.
Using a square, measure the height difference
between the two forks. The measurement
should be taken at the outermost edge of the
fork, near the battery box (see Figure 13). In
this view, the caster side (left) should be lower
than the drive tire side (right). Adjusting the
caster counterclockwise will lower the caster
side.
3.
When the caster is properly adjusted, the truck
should lean slightly towards the caster side of
the truck. The truck should never lean more
than 0.5° from vertical.
