SECTION 3
PLANNED MAINTENANCE
3-1. GENERAL.
Planned maintenance consists of periodic visual and
operational checks, parts inspection, lubrication, and
scheduled maintenance designed to prevent or
discover malfunctions and defective parts. The
operator performs the checks in
SECTION 2
,
and
refers any required servicing to a qualified mainte-
nance technician who performs the scheduled mainte-
nance and any required servicing.
3-2.
MONTHLY AND QUARTERLY CHECKS
Table 3-1 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 frequency of inspection and service should be
increased accordingly
.
These procedures must be
performed by a qualified service technician or your
EP Service Representative.
3-3. BATTERY CARE
3-3.1. General
The PDSR may be equipped with maintenance free
or industrial wet cell batteries.
The care and maintenance of the battery is very
important to obtain efficient truck operation and
maximum 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 wat-
er) applied to spilled acid until bubbling
stops, neutralizes the acid for safe hand-
ing 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 electrical 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.
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
operation of electronic devices on the unit.
