PLANNED MAINTENANCE
3-1. GENERAL.
Planned maintenance consists of periodic visual and
operational checks, parts inspection, lubrication, and
scheduled maintenance designed to prevent or dis-
cover malfunctions and defective parts. The operator
performs the checks in
, and refers any
required servicing to a qualified maintenance techni-
cian who performs the scheduled maintenance and
any required servicing.
3-2. MONTHLY AND QUARTERLY CHECKS.
is a monthly and quarterly inspection and
service chart based on normal usage of equipment
eight hours per day, five days per week. If the lift truck
is used in excess of forty hours per week, the fre-
quency of inspection and service should be increased
accordingly. These procedures must be performed by
a qualified service technician or your Global Industrial
Service Representative.
3-3. BATTERY CARE.
3-3.1. General
The 989021 is equipped with maintenance free batter-
ies.
The care and maintenance of the battery is very
important to obtain efficient truck operation and maxi-
mum battery life.
CAUTION:
Gases produced by a battery can be
explosive. Do not smoke, use an open
flame, create an arc or sparks in the
vicinity of the battery. Ventilate an
enclosed area well when charging.
CAUTION:
Batteries contain sulfuric acid which may
cause severe burns. Avoid contact with
eyes, skin or clothing. In case of contact,
flush immediately and thoroughly with
clean water. Obtain medical attention
when eyes are affected. A baking soda
solution (one pound to one gallon of
water) applied to spilled acid until bub-
bling stops, neutralizes the acid for safe
handing and disposal.
Leakage voltage from battery terminals to battery case
can cause misleading trouble symptoms with the truck
electrical system. Since components of the truck elec-
trical system are insulated from truck frame, leakage
voltage will not normally affect truck operation unless a
short circuit or breakdown of circuit wire insulation to
truck frame occurs.
A voltage check from battery connector terminal to
battery case should indicate near zero volts. Typically,
however, the sum of the voltages at both terminals will
equal battery volts. This leakage voltage will discharge
the battery. As battery cleanliness deteriorates, the
usable charge of the battery decreases due to this self
discharge.
Table 3-1 Monthly and Quarterly Inspection and Service Chart
Although a leakage voltage reading of zero volts may
not be possible, a cleaner battery will have more
usable charge for truck operation and not affect opera-
tion of electronic devices on the unit.
VISUAL CHECKS
INTERVAL
INSPECTION OR SERVICE
Monthly
Check electrical brake for proper operation.
Monthly
Check load wheels for wear. A poly load wheel must be replaced if worn to within 1/16 inch
of hub. Check for separation from hub.
Monthly
Check drive wheel for wear. A poly drive wheel must be replaced if worn to within 3/4 inch of
hub. Check for separation from hub.
Monthly
Inspect wiring for loose connections and damaged insulation.
Monthly
Check deadman brake switch for proper operation.
Monthly
Check lift chain tension, lubrication & operation (see paragraph
)
Quarterly
Check lift cylinder for leakage.
Quarterly
Check for excessive jerking of steering arm when stopping or starting.
Semi-annually
Inspect for chain wear (See
