1. Secure battery to generator using bat-
tery hold-down system. This system
consists of the battery mounting brack
-
et, hook bolts, and nuts (see Figures 9
and 10).
2. Locate the red, positive (+) battery
cable from starter solenoid. Connect it
to the positive (+) battery terminal (see
Figures 11 and 12).
3. Locate the black, negative (–) battery
cable attached to engine block. Connect
it to the negative (–) battery terminal
(see Figures 11 and 12).
4. Check battery before starting engine.
Make sure fluid levels are full. Make
sure battery is charged.
See engine owner’s manual for more

Always shut down engine before removing
or attaching battery cables. Always remove
the negative (–) cable first. Always attach
negative (–) cable last.
IMPORTANT: Make sure battery connec-
tions are the correct polarity. Electric start
generators use negative ground, 12-volt DC
starting system.
A battery is not supplied with generator. A
12-volt, 32 Amp-Hour minimum, group U1,
lug terminal battery is recommended. The
positive and negative battery cables are sup-
plied with generator. You must install these
cables before mounting battery.
Always wear safety glasses when working
with battery. Make sure battery terminals
are clean. Make sure cable connections
are tight.
CAUTION: If you remove bat-
tery, insulate the red, positive (+)
battery cable terminal. Insulate
with electrical tape. Exposed
terminal may spark when genera-
tor runs.
WARNING: Battery contains
sulfuric acid. Contact with skin
or eyes may cause severe burns.
Do not tilt generator with battery
installed. Tilting could cause bat
-
tery acid to spill. Wear protective
clothing and face shield when
servicing. Keep out of children’s
reach.
• If battery acid gets on your skin,
wash with water.
• If battery acid gets in your eyes,
flush with water at least 15
minutes. Call a doctor at once.
Battery acid is poisonous.
•
If swallowed, drink large
amounts of water or milk. Fol-
low with milk of magnesia or
vegetable oil. Call a doctor at
once.
WARNING: Battery gives off
explosive gases. Keep sparks,
flames, and cigarettes away. Do
not remove or install battery
cables when engine is cranking
or running. Only service or use
battery in a well-vented area.
