BATTERY
WARNING
w
DO NOT connect the battery charger plug
to the lift truck.
w
Read the battery charger manual before
charging batteries.
w
DO NOT smoke or use spark-producing
devices near the battery.
w
DO NOT expose the battery to open flames.
w
Always change batteries in a well-ventilated
area to avoid hydrogen gas concentration.
w
Clean batteries regularly; corrosion causes
grounds and the possibility of sparks.
w
Keep plugs, terminals, cables, and recep-
tacles in good condition to avoid shorts and
sparks.
w
Charge batteries at the indicated rates.
w
DO NOT lay tools, chains, or other metal
objects on top of the battery.
w
Always wear protective clothing and eye
protection when handling, checking, or
filling batteries.
w
DO NOT overcharge the battery.
w
Ensure charger voltage is correct for the
battery being charged.
Refer to APPENDIX A: INDUSTRIAL BATTERY
for detailed battery safety precautions.
1.
Give the battery an EQUALIZING CHARGE,
using a charger designed for the battery.
This charge is at a low rate and balances the
charge in all of the cells. The equalizing
charge is usually for 3 hours at a low rate, in
addition to the regular charging cycle. The
most accurate specific gravity measurements
for a charged battery will be after an
equalizing charge.
2.
Check with the manufacturer of your battery
or with your dealer for a suitable
battery/charger combination and for specific
details about the equalizing charge for your
battery.
CONTACTOR TIPS
WARNING
Disconnect the battery and discharge the
capacitor bank (refer to the ELECTRICAL
section) before making any inspections or
repairs to the contactor.
In normal operation, the contact surfaces become
rough and turn a dark color. Cleaning is usually
not necessary as this does not interfere with
proper operation. The contact surfaces are silver
alloy on a copper base. Replace the contacts
when the silver surface wears through to the
copper base. Always replace the contacts in sets.
Refer to CONTACTOR TIP Removal /
Replacement procedures in the ELECTRICAL
section.
GEARBOX
Park the lift truck on a level surface. Check the
oil level in the gearbox by removing the fluid level
plug on the side of the gearbox. The fluid level
should be even with the bottom of the hole.
CAUTION
DO NOT permit dirt to enter the gearbox.
HYDRAULIC SYSTEM
Check the breather cap for accumulation of
material that could prevent the easy passage of
air.
LIFT CHAINS
WARNING
DO NOT work under a raised carriage. Lower
the carriage and forks to the ground or use a
suitable locking device to prevent the carriage
and rails from lowering when performing
maintenance.
1.
Inspect the chains for accumulation of dirt,
especially if the lift truck is operated in dusty
