Planned Maintenance; General; Monthly And Quarterly Checks; Battery Care - Big Joe M22 Installation, Operation, Maintenance & Repair Parts

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
required servicing to a qualified service Technician
who performs the scheduled maintenance 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 fre-
quency of inspection and service should be increased
accordingly. These procedures must be performed by
a qualified service technician or your Big Lift LLC Ser-
vice Representative.
INTERVAL
Daily Check battery condition. Check cables for good contact with terminal posts.
Daily Observe performance of truck. Check any improper operation.
Weekly Check floor lock.
Monthly Inspect hoses and fittings for leaks.
Monthly Check wiring for loose connections and damaged insulation.
Monthly Check load wheels for wear.
Monthly Check caster wheels for wear.
Monthly Check lift chain tension, lubrication & operation (see paragraph 3-6.)
Quarterly Check lift cylinder for leakage.
Semi-annually Inspect for chain wear (See
BL-M22EP-0119 - 01-11-2019

3-3. BATTERY CARE.

3-3.1. General
The care and maintenance of the battery is very
important to obtain efficient truck operation and maxi-
mum battery life.
Leakage voltage from battery terminals to battery case
can cause misleading trouble symptoms with the
truck's electrical system. Since components of the
truck's 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 opera-
tion of electronic devices on the unit.
