1. SAFETY INSTRUCTIONS
to do so could result in personal injury or equipment damage.
Exhaust gas contains poisonous carbon monoxide. Never run the charger in an
enclosed area.
Be sure to provide adequate ventilation.
The muffler becomes very hot during operation and remains hot for a while after
stopping the engine.
Be careful not to touch the muffler while it is hot.
Let the engine cool before storing the charger indoors.
The engine exhaust system will be heated during operation and remain hot immediately after
stopping the engine.
To prevent scalding, pay attention to the warning marks attached to the charger.
American Power Systems charger is designed to give safe and dependable service if
operated according to instructions.
Read and understand the Owner’s Manual before operating the charger. Failure

TO ENSURE SAFE OPERATION
Gasoline is extremely flammable and explosive under certain conditions.
Refuel in a well ventilated area with the engine stopped.
Keep away from cigarette, smoke and sparks when refueling the charger.
Always refuel in a well-ventilated location.
Wipe up spilled gasoline at once.
Connections for standby power to a building’s electrical system must be made
by a qualified electrician and must comply with all applicable laws and
electrical codes. Improper connections can allow electrical current from the
charger to back feed into the utility lines. Such back feed may electrocute utility
company workers or others who contact the lines during a power outage, and
when utility power is restored, the charger may explode, burn, or cause fires in
the building’s electrical system.
Always make a pre-operation inspection before you start the engine. You may
prevent an accident or equipment damage.

- 3 -
Place the charger at least 1M (3ft) away from buildings or other equipment during operation.
Operate the charger on a level surface. If the charger is tilted, fuel spillage may result.
Know how to stop the charger quickly and understand operation of all the controls. Never permit
anyone to operate the charger without proper instructions.
Keep children and pets away from the charger when it is in operation.
Keep away from rotating parts while the charger is running.
The charger is a potential source of electrical shocks when misused; do not operate with wet
hands.
Do not operate the charger in rain or snow and do not let it get wet.

3. PRE-OPERATION INSPECTION
Be sure to check the generator standing on a
horizontal level surface with the engine stopped.
Do not connect to mains supply power.
Do not connect the generators in parallel.
Connections for standby power to a building’s electrical
system must be made by a qualified electrician and must
comply with all applicable laws and electrical codes.
Improper connections can allow electrical current from the
generator to backfeed into the utility lines. Such backfeed
may electrocute utility company workers or others who
contact the lines during a power outage, and when utility
power is restored, the generator may explode, burn, or
cause fires in the building’s electrical system.
WARNING

3.1 Check the engine oil level
■Using non-detergent oil or 2-stroke engine oil could shorten the engine's
service life.
Oil is a major factor affecting performance and
service life. Use 4-stroke automotive detergent
oil.
SAE15W/40 is recommended for general use.
Other viscosities shown in the chart may be used
when the average temperature in your area is
within the recommended range.
The SAE oil viscosity and service category are in
the API label on the oil container. We
SJ or later (or equivalent) oil.
Running the engine with insufficient oil can caused serious engine damage.
CAUTION
CAUTION
recommend that you use API service category

Remove the oil filler cap, and wipe the dipstick with a clean rag, check the oil level by inserting the
dipstick in the filler hole without screwing it in. If the oil level is below the end of the dipstick, refill the
recommended oil up to the top of the filler neck.
Engine oil capacity: 0.4 L

- 10 -
3.2 Check the fuel level
Use automotive gasoline (Unleaded is preferred to minimize combustion chamber deposits).
If the fuel level is low, refuel the fuel tank until the level
as specified. Do not overfill. Wipe up spilled fuel
before starting the engine.
Never use an oil /gasoline mixture or dirty gasoline.
Avoid getting dirt, dust or water in the fuel tank.
After refueling, tighten the fuel tank cap securely.
Fuel tank capacity: 4.2 L
Gasoline is extremely flammable and is explosive under certain conditions.
Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in
the area where the engine is refueled or where gasoline is stored.
Do not overfill the fuel tank (there should be no fuel above the upper limit mark). After refueling,
make sure the fuel tank cap is closed properly and securely.
Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite, if any fuel is spilled,
make sure the area is dry before starting the engine.
Avoid repeated or prolonged contact with skin or breathing of vapor.
KEEP OUT OF REACH OF CHILDREN.

4. STARTING THE ENGINE
a. Turn the fuel cock to “ON" position.
b. Turn the engine switch to “ON " position.
Before starting, do not connect
the battery.

c. Turn the choke lever to “START" position.
CHOKE LEVER
■Do not use the choke when the engine
is warm or the air temperature is high.
d. Pull slowly on recoil start until engaged
then pull it briskly.
■Do not allow the start grip to snap back,
return it slowly by hand.
e. Move the choke lever to the “RUN”position after the engine warms up.

5. CHARGING FOR THE BATTERY
Do not exceed the current limit specified for any one receptacle.
damage to the charger or to electrical appliances in the house.
Do not modify or use the charger for other purposes than it is intended for. Also observe the
following when using the charger.
Do not connect charger in parallel.
Do not connect an extension to the exhaust pipe.
When an extension cable is required, be sure to use a touch rubber sheathed flexible cable.
Limit length of extension cable: 1.3M for cables if 4.0mm2.
Keep the charger away from other electric cables or wires such as commercial power supply lines.
Most chargers require their rated wattage.
The battery charger should be operated on a clean surface, such as the
vehicles rubber floor mat.
NOTE
CAUTION
Do not connect the charger to a household circuit. This could cause

This charger is designed for recharging 1N70 sized battery only. Charging larger battery capacities
will cause overheating or stall the engine.
Deep cycle batteries can be charged with this charger, but some will not accept a fast recharge &
may require a slow trickle charging for a long period of time, which may not be the most efficient
system.
Batteries contain a sulphuric acid electrolyte, which is a highly corrosive
poison that will produce gasses when recharged and can explode if ignited.
This can cause serious injury or possibly death.
The battery gives off explosive gases; keep spark, flames and cigarettes away. Provide adequate
ventilation when charging.
Wear protective clothing and a face shield.
If electrolyte gets on your skin, flush with water.
If electrolyte gets in your eyes, flush with water for at least 15 minutes and call a physician.
KEEP OUT OF REACH OF CHILDREN.
WARNING
The battery contains sulfuric acid (electrolyte). Contact with skin or eyes may cause sever burns.

OPERATING THE CHARGER
a. Start each engine according to “STARTING THE ENGINE”,
and the readout on the digital display should be 0.00 to
-0.03.
Never reverse the polarities, as it may cause severe damage or may cause an explosion due to the
hydrogen gases produced during charging

battery can be charged quickly.
d. During the charge course, the readout on the “CHARGE CURRENT
DISPLAY”will decrease slowly. The lead acid battery should be fully
charged when the amp readout didn’t come down any more. The value
depends on the battery size.
Some deep cycle batteries will take much longer to charge, as a fast surface charge will build up on
the internal plates, causing the amp input to cut back to a slow trickle charge.
e. The 60amp charger is designed for recharging 1 N70 car battery only, do not use this on large solar
installations, if used with larger battery capacities the charger may overheat and cause failures to
electronic components.
c. The max charge current of this charger is 50A/12V, and the voltage is 15V, so the
