PREFACE
Thank you for choosing a general gasoline engine by our company.
Based on the latest engine technology at home and abroad, our Co. has individually developed
general gasoline engines with 4-stroke single cylinder, OHV and forced-air cooling. The engine is
characterized by advanced design, compact structure, reliable performance, convenient service low
fuel consumption and easy speed adjustment. They are widely used as ideal power in many fields such
as generating set, tour, open working, public place of entertainment, construction machine, agricultural machinery, etc. the vital part bodies including cylinder cover, crankcase, etc, are all cast formed
with aluminum alloy. Laser-scanning technology, 3D shaping technology and CN program processing
technology used in the mould production upgrade the engine surface and manufacturing accuracy obviously. Applying auto-press reducing system and centrifugal fly hammer regulating system assure
that assemblies equipped with the engine function smoothly and reliably as well as the engine start
easily. Besides, the introduction of the lubricant film-sensing protection system prevents accidental
damage of the engine for poor lubrication.
The manual gives information with respect with respect to operation and maintenance of the
general gasoline engine, and be sure to read it carefully first before operating. All the materials and
diagrams of this manual are in accordance with the newest products at the publishing time. Due to revision and other change, the information descried in this manual may be a little different form the ac-

● Before operating the engine, be sure to read and familiar with the manual carefully,
otherwise injury to personnel or damage to equipment may occur.
Please pay special attention to the following:
1. Running the engine in a well-ventilated place, keep it at least one meter away from building walls
or other equipments, keep away from inflammables such as gasoline, matches and so on to avoid
possibility of fire.
2. Keep the engine out of reach of children and pets to avoid accidents.
3. Operator on the engine has been specially trained.]
4. Refuel in a well-ventilated area with the engine stopped, and in places refueling or storing gasoline,
no smoking and any flames or sparks.
5. Refuel the fuel tank not too full so as to avoid fuel’s spilling out. If there is spilled fuel around, be
sure to clean it thoroughly before starting.
6. Locate the engine on a level-working platform to avoid fuel’s spilling out.
7. Mack sure the fuel filler cap is tightened securely.
8. The exhaust muffler is very hot during running the engine even after the engine stops. Never touch
it, or you may get burns. Transport or store the engine with it cooling down entirely.

BATTERY CONNECTION (electric-start type)
In the case that the specifications of the battery are 12V and more than 18A.h, connect its positive lead to the electromagnetic coil while connect its negative lead to engine mount strew, base screw
any place capable of grounding with the engine well.
Make sure the battery leads are connected tightly and no corrosion is found. If any, eliminate it.
△! WARNING
● The battery may give or off explosive gas, keep sparks, flames and cigarettes away.
Charge or use it I an area with gook ventilation.
● The battery contains sulphonic acid (electrolyte). Con tact with skin or eyes may causr
severe burns. Wear protective clothing and a face shield.
If electrolyte gets in your skin, flush with water; if gets in your eyes, flush with water for
at least 15 minutes and call a physician at once.
● Electrolyte is poisonous. If swallowed, drink large quantities of water or milk, and follow
with milk of magnesia or vegetable oil and call a physician.
● Keep out of reach of children.
CAUTION
● Do not add tap water to the battery instead of distilled water, or the battery life will be
shortened.

PRE-OPERATE INSPECTION
Ⅰ.ENGINE OIL
CAUTION
● Engine oil is a key factor in deciding the engine’s performance. Do not apply engine oil
with additives or 2-stroke gasoline oil, as they haven’t enough lubrication, which may
shorten the engine’s service life.
● Check the engine with it stopped on a level ground.
Engine oil recommended: SAE10W-30 (Fig.5)
As viscosity varies with regions and temperatures, so the lubricant has to be selected in a accordance with our recommendation.
Check (Fig.6)
1. Ensure that the engine is stopped on a level ground.
2. Remove the dipstick and clean it.
3. Reinsert the dipstick into the oil filler without
screwing in, and check oil level.
4. If the oil level is too low, add recommended engine
oil to the filler neck.
5. Reinstall the dipstick.

CAUTION
● Run with insufficient engine oil may damage the engine severely.
Ⅱ. OIL IN THE REDUCTION GEAR BOX (only for the model equipped with it)
1/2 Reduction gear box with an auto-centrifugal clutch.
Brand of the oil is the same as that of engine oil.
Oil capacity: 0.50 liters
Check the oil level in the following order (Fig. 7)
1. Remove the dipstick and clean it.
2. Reinsert the dipstick without screwing it in, and then take out it and check oil level.
3. If the oil level is too low, and recommended engine oil until it arrives the upper level mark.
4. Reinstall the dipstick.

3. Semi –dry type (Fig. 10)
a) Remove the air cleaner housing and check
the filter element for dirt and impurity.
Clean or replacement should be done if
necessary.
b) Check the air cleaner for dirt, and remove it
if any.
4. Oil – bath type (Fig. 11)
a) Dismantle the air cleaner housing and check
its core, make sure it is clean and intact, oth erwise clean or replace it.

CAUTION
● Never run the engine without an air cleaner, or sever wear of the engine may occur.
Ⅳ. FUEL AND FUEL TANK
1. Fuel
The engine must apply unleaded gasoline with an octane number over 86. Using unleaded gasoline will decrease the possibility of producing carbon deposit and prolong the engine’s service life.
Never apply used or polluted gasoline or a mixture of gasoline and engine oil. Make sure the fuel
is free of dirt and water.
2. Gasoline Containing Alcohol
If you decide to use a gasoline containing alcohol (fuel blend), be sure its octane rating it at least
as high as that recommended by the company. There are two types of “gasohol”. One contains ethanol,
and the other contains methanol. Neither gasoline containing more than 10% ethanol nor 5% methanol
is allowed to be used. If methanol content in the fuel blend exceeds 5%, it may bring bad effect on the
engine performance, besides, it may damage metals, rubber and plastic parts.
CAUTION
● Handle fuel with care because it can damage plastic and painted surfaces.
● It is normal when you hear occasionally light spark knock or pinking with the engine run-
ning under heavy load.
● Should spark knock or pinking be heard at a speed under normal load, change brand of
gasoline; if such phenomenon still happens, consult your dealer for help, otherwise, the

engine may be damaged.
3. Fuel Tank
Fuel tank capacity: 2.5liters for 160F, and3.6liters for 168F ＆ 168F – 2.
4. Check
a) Remove the fuel filler cap and check fuel level.
b) If the fuel level is too low, refuel the tank. Remember adding fuel not over the fuel filter
shoulder (Fig. 12).
