WARNING
Safety operation instructions
1. Exhaust contains poisonous carbon monoxide, a colorless and
odorless gas. Breathing exhaust can cause loss of consciousness
and may lead to death. Do not operate the engine without good
ventilation or in enclosed room.
If you run the engine in an area that is confined, or even partially
enclosed, the air you breathe could contain a dangerous amount of
exhaust gas. To keep exhaust gas from building up, provide adequate
ventilation .
2. Place the engine on level surface, engine’s tilt can not over 20º,
otherwise it will leads to fuel spill out.
3. Do not cover the engine, to avoid fire occur.

4. The engine has spark arrestor, it may break the law if you operate
the engine without spark arrester. Please enquiry local regulations
and code before operating.
5. The muffler becomes very hot during and immediately after
operation. Be careful not to touch the muffler while it is hot. Let
the engine cool down before storing the engine indoor.

2. PRE-OPERATION CHECK
1. Check the oil level
(1) Lubricant oil
CAUTION:
·Engine lubricant oil is a major factor affecting engine performance
and service life. Non-detergent and 2-stroke engine oils will damage
the engine and should not be used.
·Before checking engine lubricant oil, place the engine on level
surface.
Use 4-stroke motor lubricant oil that meets or exceeds the
requirements for API service classification SF or SG. Always check
the API service label on the oil container to be sure it includes the
letters SF or SG.
2-1
SAE10W-30 is recommended for general, all temperature use. Other
viscosities shown in the chart may be used when the average
temperature in your area is within the indicated range.
·Make sure that engine on level surface.

·Turn out the oil filler cap and clean the dipstick with a clean cloth.
·Insert the dipstick back into the oil filler hole without turning it in.
·If oil level is below the lower mark of the dipstick, fill oil to the
upper level of the dipstick.
·Reinstall the oil filler cap well.
Low-speed gear oil (only for optional function)
(Auto-centrifugal clutch, 1/2 speed)
·Turn out the oil filer cap and clean the dipstick.
·Insert the dipstick back into the oil filler hole without turning it in.
·If oil level is low and need to refill, be sure engine oil use
recommended oil.

2. FUEL LEVEL
·Check the fuel gauge, and refill the tank if the fuel level is low. Do
not fill above the shoulder of the fuel strainer. The fuel 90# gasoline
is recommended.
·Unleaded gasoline produces less engine and spark plug fouling and
extends exhaust system life.
·Never use stale or contaminated gasoline or oil/gasoline mixture.
Avoid getting earth, rubbish and water into the fuel tank.
·If spark knock or pinging occurs at a steady engine speed under
normal load, change brands of gasoline. If spark knock or pinging
persists, see an authorized dealer.
WARNING:

·Running the engine with persistent spark knock or pinging can
cause engine damage.
·It is misuse of the unit to run the engine with persistent spark
knocks or pinging, and the Distributor’s Limited Warranty does not
cover parts damaged by misuse.

·Check bolts, fasten loose ones.
·Check whether lubricant oil level is at ranged limits.
2. Clean the core after the unit working up to 25hrs,.
3. Clean carbon fouling of the spark plug after working up to 50hrs.
Check the clearance, and adjust the gap to 0.6-0.7mm (see figure 4-1).
Check radiator, and clean fouling among radiators.

5. TROUBLESHOOTING
Have the engine checked if it is hard to or cannot be started.
Firstly, check the fuel level of the fuel tank. Turn fuel valve to (2),
Fuel should flow from the drain when the fuel valve is turned ON.
Tighten the drain plug. (see figure 3-1)
Secondly, check the spark plug. Remove the spark plug cap and clean
any dirt around it. If the engine still cannot be started after repeating
several times, please see the authorized dealer. Users are not allowed
to dismantle or reassemble the unit by themselves.

6. Maintenance Before Long-Time Storage
If the engine is not used for long time, do the necessary maintenance
before its storage.
Firstly, take off the fuel tank, drain out all fuel, and clean the dirt and
water inside the tank. Open the fuel cock, unscrew the drain plug at
the bottom of carburetor, drain out fuel in carburetor thoroughly, and
then tighten the drain plug.
Secondly, unscrew the drain plug at the bottom of the crankcase and
drain out the lubricant oil in the crankcase thoroughly, then tighten
the drain plug.
Finally, clean the surface of the engine with clean cloth, remove the
dirt and dust etc. Then store the engine in a well-ventilated, dirt-free
place.
