MAINTENANCE INSTRUCTIONS
R OUTINE M AINTENANCE
Before performing any maintenance or repair work,
isolate the batteries from the motor and electronics by
opening the circuit breaker in (Figure 13). Simply push
the red push button until the red side lever fully opens
as shown in Figure 14. To close the circuit breaker,
simply push the red side lever to its original closed

B ATTERIES
The standard batteries used on Pack Mule vehicles are 6
volt lead acid. This manual is written around the lead acid
batteries. Batteries have a maximum life. Therefore, good
maintenance is important to maximize the available life of
the vehicle’s batteries.
B ATTERY S AFETY
Always observe the following warnings when working on or
near batteries:
To prevent burns or battery explosion that could result
in severe personal injury or death, keep all smoking
materials, open flame or sparks away the batteries.
Hydrogen gas forms when charging batteries. Do NOT
charge batteries without adequate ventilation. Only a
4% concentration of hydrogen gas is explosive.
Be sure the key switch or on/off switch is in the OFF
position and all electrical accessories are off before
starting work on the vehic
le. Open the vehicle’s circuit
switch as shown in Figure 24 before starting work on
the vehicle.
The electrolyte in a lead acid battery is an acid solution
which can cause severe burns to the skin and eyes.
Treat all spills to the body and eyes with extended
flushing with clear water. Then contact a physician
immediately.
Always wear approved safety goggles or
face shield when handling or working
around batteries.
Electrolyte spills will corrode the vehicle’s structural
frame and body if not properly treated immediately. In
the event of a spill, wear proper protective clothing,
gloves, and eye wear. Thoroughly clean all affected
areas with a neutralizing solution of ¼ cup (60 mL)
sodium bicarbonate (baking soda) dissolved in 1 ½
gallons (6 L) of water.
It is highly recommended that insulated wrenches be
used
when working on our electric vehicles.
Alternatively, wrap wrenches with vinyl tape to prevent
the possibility of a dropped wrench onto the batteries
terminals, which can short the battery, which could
result in an explosion and severe personal injury or
death.
B ATTERY C ARE
1) Place battery into service and complete a full discharge
and charge cycle. Check and add approved water only
(never acid) if needed only after this first cycle is
completed.
2) Never discharge battery beyond 80% and do not
operate battery if the specific gravity is below 1.150
3) If above 115
o
F (46
o
C) allow battery to cool before
charging or operating
4) During shipment or prolonged storage the electrolyte
levels may fall below the separator protector. Only after
a complete discharge and charge cycle, check and keep
electrolyte level above separator and 1/8” (3.175mm)
below vent well. Add approved water only when
required and never add acid.
5) Keep battery top clean, dry and vent caps tightly in
place.
