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 dis-
cover malfunctions and defective parts. The operator
performs the checks in
SECTION 2 , 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.
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 Joe service
representative.
3-3. BATTERY CARE.
These batteries are maintenance-free. Any attempt to
open the battery will void the warranty.
Ultra-deep discharging of brand new batteries
should be avoided for at least 15 cycles. To dramat-
ically extend battery life, ultra-deep discharge should
be avoided. The shallower the average discharge, the
longer the battery life.
Charge the battery as described in paragraph 3-4.
3-4. CHARGING BATTERIES
Charging requirements will vary depending on depth of
discharge and temperature. Follow safety rules when
placing a battery on charge.
Proceed as follows:
1. Park truck at charging station with carriage low-
ered and key switch and disconnect switch off.
2. Check the condition of the AC cord, the battery
connector and battery cables. If there are any cuts
in the cable, any exposed wires, loose plugs or
connectors, DO NOT attempt to charge the bat-
teries. Contact appropriate personnel for repairs
to be made.
3. Connect the charger to connector (13, Figure 12-
9 ). Switch (8) will automatically disconnect the
batteries to from the truck. Make sure connectors
are mated properly.
