A 12-volt booster battery can be connected in parallel with
battery(ies) on the unit to aid in cold weather starting.
ALWAYS use heavy duty jumper cables.
CAUTION: Gas given off by batteries is
explosive. Keep sparks and flames away from
batteries. Before connecting or disconnecting a
battery charger, turn charger off. Make last
connection and first disconnection at a point
away from battery. Always connect NEGATIVE
(–) cable last and disconnect this cable first.
IMPORTANT: Be sure polarity is correct before
making connections. Reversed polarity
will damage electrical system. Always
connect positive to positive and
negative to ground. Always use 12-volt
booster battery for 12-volt electrical
systems and 24-volt booster battery/
batteries for 24-volt electrical systems.
1. Connect booster battery or batteries to produce the
required system voltage for your engine application.
NOTE: To avoid sparks, DO NOT allow the free ends of
jumper cables to touch the engine.
2. Connect one end of jumper cable to the POSITIVE (+)
post of the booster battery.
3. Connect the other end of the jumper cable to the
POSITIVE (+) post of battery connected to starter.
4. Connect one end of the other jumper cable to the
NEGATIVE (–) post of the booster battery.
5. ALWAYS complete the hookup by making the last
connection of the NEGATIVE (–) cable to a good
ground on the engine frame and away from the
battery(ies).
6. Start the engine. Disconnect jumper cables
immediately after engine starts. Disconnect NEGATIVE
(–) cable first.
