f. Jump-Starting with an Auxiliary (“Booster”)
Battery
Note: Use this information in addition to that found in
the appropriate Owners/Operators Manual.
Both the auxiliary or “booster” battery and the discharged
battery should be treated carefully when using jumper
cables. Follow the following procedure exactly, and DO
NOT cause sparks to occur:
1. Engage the park brake of the booster vehicle and
place its transmission in (N) NEUTRAL. DO NOT
allow both vehicles to touch each other in any
manner, as this could establish a ground connection
and counteract the jump-starting process.
2. Continue with the jump-starting instructions found in
the appropriate Owners/Operators Manual.
g. Battery Removal
1. Unlock and open the engine cover (1).
2. If the vehicle has dual batteries, disconnect both
negative battery cables (3 and 4) from both
batteries.
To access the lower battery (5), loosen the knob (6)
far enough so that the lip (7) on the upper battery box
clears the knob. Lift up the upper battery box (8) and
swing it out, so that the box clears the hydraulic tank
support bracket, to gain access to the lower negative
battery cable (3). Disconnect the lower negative
battery cable.
3. Disconnect the positive (+) battery cable (9) at the
positive (+) terminal on the battery.
If you have dual batteries and the lower battery needs
to be replaced, both positive battery
cables (9 and 10) must be disconnected from both
batteries.
WARNING:
Any other procedure other
than that outlined in these instructions could
result in:
• Personal injury caused by electrolyte
spewing out of the top vent holes on the
battery.
• Personal injury or property damage due to
battery explosion.
• Damage to the starting systems of both
vehicles.
