Front (Drive) Tire - UniCarriers 1F1 Operator's Manual

Front (Drive) Tire:

1. Place the lift truck on a level and solid surface.
2. Start the engine and raise the carriage about 250 mm (9.84 in).
3. Place chocks behind the rear wheels to prevent movement of the
lift truck.
4. Loosen the wheel nuts one or two turns each by turning the
counterclockwise.
5. Tilt the mast fully backward, place a wooden block under each side
of the outer mast.
6. Tilt the mast forward until the front tires are raised from the surface.
!
WARNING
• Do not operate the control lever quickly. Doing so may cause
the mast on wood blocks on the ground to become unstable.
• Stop jacking up the lift truck when the tires are slightly raised
off the ground. Jacking up the lift truck excessively high
could cause it to roll over.
• If the front wheels are lifted for a long time by means of the
mast, the mast may incline backward by itself. To prevent
this, be sure to insert wood blocks under each side of the
frame with no space left between them.
• Do not remove the wheel nuts until the front tires are raised
off the ground.
7. Support the lift truck by putting additional wood blocks under each
side of the front-end of the frame as shown at left. Stop the engine.
8. Remove the wheel nuts and replace the front tire.
!
• When removing the tire from the wheel rim, do not remove
the rim set bolts and wheel nuts before releasing the air
(pneumatic model only).
• Never get under the lift truck while it is supported only by the
wood blocks.
9. Reinstall the wheel nuts and temporarily tighten them in the
sequence as shown.

!
• Each wheel nut has a conical bearing surface and each hole
in the rim is countersunk so that they can fit with each other.
After attaching all wheel nuts, make sure each nut tightly
fits with the countersunk hole. If wheel nuts are attached in
the wrong direction, they will loosen easily and might cause
bolts to break and the wheel to come off.
