Hyster F003, Service & Repair Manual

Page: 9 / 21

When adding air to tires, use equipment with a gauge
or preset pressure regulator and a clip-on chuck.
Make sure the hose is long enough to avoid being in
the path of the wheel parts in case of an explosion.
WARNING
Stay clear of the path of wheel parts in
case of an explosion.
If it is necessary to add air to a tire that is warm,
check one of the other tires. Add air to the tire with
low pressure so that the air pressures are equal. The
tire pressure of warm tires must always be equal to or
greater than tire pressure specified for cold tires.
Check that all of the wheel nuts are tight. When the
wheels are removed and installed again, check the
nuts for the correct torque as shown in MAINTE-
NANCE every eight hours. When the nuts stay tight
after an eight hour check, the interval for checking
with a torque wrench can be extended to 350 hours.
Lift Mechanism
WARNING
Lower lift mechanism completely. Never
stand under a raised carriage.
Do not put any part of the body in the lift
mechanism unless all parts of the upright
are completely lowered and the engine is
OFF.
Always block or chain the upright weld-
ments and carriage before inspecting the
upright or attempting any repairs.
Forks (Item 9)
A. Check that the tips are aligned within 13 mm (0.5
inch) of each other (I).
WARNING
Do not try to correct the alignment by
bending the forks or adding shims. Re-
place bent or damaged forks.
B. Check for cracks (2) in the heel of the forks and at
the attachment points.
WARNING
Never repair damaged forks by heating
or welding. Forks are made of special
steel using special procedures. Replace
damaged forks.
C. Check for cracks (2) or damage (4) in the fork
hooks or pins. Replace as necessary.
Lift Chain (Item 10)
A. Check the lift chain for the proper lubrication.
B. Inspect the lift chain for cracks or broken links
and pins. Check for corrosion or worn holes in the
links. When the pins or holes become worn, the chain
becomes longer. If a section of chain is 3~q longer
than the section of new chain, the chain is worn and
must be replaced.
If a chain scale is available, check the lift chain as
shown. If a chain scale is not available, measure 20
links of chain. Compare the length with the chart in
Figure 9. Replace the chain if the length of 201inks of
the worn section is more than the maximum wear limit.
WARNING
If one chain has a defect, replace both
chains. Do not try to repair a worn chain.
D. Check each latch for proper operation. The latch
should securely lock the fork to the carriage.
