When overload occurs and power generation
stops, proceed as follows:
1. Turn off any connected electric devices and
stop generator.
2. Reduce total wattage of connected electric
devices within application range.
3. Check for blockages in cooling air inlet and
outlet areas and around control unit. If any
blockages are found, remove them.
4. After checking, restart generator.
Battery Charging Using DC Receptacle
Electrical Shock can cause injury.
Do not touch wires while
generator is running.
Never operate generator in rain or snow.
Never touch generator with wet hands or
electrical shock may occur.
NOTE: This section refers to charging 12V
batteries in other equipment like motor
vehicles or off-road vehicles. No
jump-starting is possible.
NOTE: Follow safety procedures when
handling batteries to avoid damage to
electrical components and battery
explosions. Refer to battery
manufacturers safety data sheet on
safety risks of working with batteries.
Refer to battery manufacturer's
instruction on battery charging/
maintaining procedures.
NOTE: Generator DC rated voltage is 12V DC
circuit protector (F) will turn off
automatically if current above rated
flows during battery charging. Start
generator first, then connect generator
to battery for charging. Before starting
to charge battery, ensure DC circuit
protector (F) is in RESET position. If
DC circuit protector (F) turns off again,
stop charging battery immediately and
contact a Kohler portable dealer.
NOTE: Do not connect a VRLA (valve
regulated lead acid) battery. To charge
a VRLA battery, a special (constant-
voltage) battery charger is required.
NOTE: Do not connect any load to battery or
use engine starter motor while
charging. This causes high current to
flow through generator which will burn
out coil.
NOTE: Prior to charging battery, remove
positive and negative cables to battery.
1. Start generator.
2. Press DC circuit protector (F) in.

3. Connect red battery charger lead to positive
battery terminal. Connect black battery
charger lead to negative battery terminal. Do
not reverse these positions. Connect cord to
DC receptacle (H).
Operating Range of DC Power Supply
(Charging 12V battery only):
This power source is designed to charge
batteries up to 40Ah that are half-discharged.
Do not charge batteries of a higher capacity
than 40Ah.
12V Battery:
Time required for recharging a battery varies
depending on discharge level of battery. When
specific gravity of battery reaches 1.26 to 1.28,
charging is complete. When charging, check
battery's specific gravity once an hour. Average
time for charging a half-discharged 40Ah
battery is approximately 5 hours. Be sure to
check battery fluid level before charging.
DC Circuit Protector
NOTE: Reduce load of connected electric
device below specified rated output of
generator if DC circuit protector (F)
turns off. If DC circuit protector (F)
turns off again, stop using device
immediately and contact a Kohler
portable dealer.
DC circuit protector (F) button will pop out,
stopping power to DC receptacle (H) when
electric device being connected to generator is
operating at current above rated flows. To use
this equipment again, press DC circuit protector
(F) button.
Starter Battery
As battery (S) is maintenance-free, just check
condition and tightness of connections and its
general cleanliness.
Circuit Breaker
Generating set's electrical circuit is protected
by one or more magnetothermal, differential or
thermal cut-out switches. If an overload and/or
short circuit occurs, supply of electrical energy
may be cut.
If necessary, replace circuit breaker (E) in
generating set with circuit breakers with
identical nominal ratings and specifications.
Cleaning Generator Set
1. Remove all dust and debris from around
exhaust silencer.
2. Clean generator and in particular air inlets
and outlets of engine and alternator using a
cloth and a brush.
3. Check general condition of generator and, if
necessary, replace any faulty parts.
