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 engines are 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.

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。 As viscosity varies with regions
and temperatures, so the Lubricant has to be selected in accordance with
our recommendation. (Pic.1)
(Pic.1)
Inspect step:
1. Remove the dipstick and clean it. (Pic. 2)
2. Reinsert the dipstick into the oil filler without
Screwing in, and check oil level.
3. If the oil level is too low, add recommended engine oil to the filler neck (Pic.2)
8
4. 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 gearbox with an auto-centrifugal clutch.
1. Remove the dipstick and clean it. (Pic. 3.)
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.
Brand of the oil is the same as that of engine oil.
Oil capacity: 0.50 liters
（Pic.3）
9
Ⅲ. AIR CLENANER(Pic. 4)
CAUTION
Never run the engine without an air cleaner, or severe wear of the engine may occur.
(Pic. 4)
Dismantle the air cleaner housing and check its filter element, make sure it is clean and intact, otherwise
clean or replace it.
Ⅳ. FUEL
1. Gasoline is extremely flammable and may explosive under certain conditions.
2. Refueling in a well – ventilation area with the engine stopped. Do mot smoke and allow flames or sparks
In the area where gasoline is stored or where the fuel tank is refueled.
3. Do not overfill the tank (there should be no fuel in the filler neck). After refueling, make sure the fuel tank cap is
set back securely.
10
4.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 enough before starting the engine.
5. Avoid repeated or prolonged contact with skin or breathing of fuel vapor. Keep out of reach of children.
Fuel tank capacity: 3.6liters
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.
CAUTION
●Handle fuel with care because it can damage plastic and painted surfaces. It is not in our guarantee range of
damage by fuel spilling.
●It is normal when you hear occasionally light spark knock or pinking with the engine running 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.
CAUTION
The engine would be damage when it is running with constantly knock or pinking noise. It is not in our warranty
range that its damage by misusage the engine
11
STARTING OF THE ENGINE
1.Push the fuel switch to “ON”. (Pic.5) 2.Push the chock lever to “OFF”. (Pic.6)
(Pic.5) (Pic.6)
NOTE
If the engine is hot, closing the choke is unnecessary.
3.Move left the throttle lever a little. (Pic.7)
(Pic.7)
12
4.Start the engine
a). Rope handle Starter.
Push the engine switch to “ON”. (Pic. 8) Pull slightly the starting rope handle up until feeling anti-action, and
then make a rapid pull. (Pic. 9)
(Pic. 8) (Pic. 9)
CAUTION
Releasing the handle suddenly may make it hitting the engine. Release the handle slowly conforming to its
recoiling force.
13
CAUTION
Use the engine switch not more than 5 second each time to avoid damage of the engine. Try once more 10
second later after last attempt failures.
Once the engine starts, reset the engine switch to “ON”.
OPERATION
1. Preheat the engine and push back the 2. Set the throttle lever in proper position to ensure
choke lever to “ON”.(Pic.10) the engine runs at required velocity.(Pic.11)
(Pic .10) (Pic .11)
14
Engine Oil Alarm
The engine oil alarm is designed to alarm the user the fact that the engine oil in the crankcase in insufficient.
Run with insufficient engine oil may damage the engine. Once oil level in the crankcase is too low, the engine oil
alarm will stall the engine automatically to make it free of damage while the engine switch is still at “ON”.
CAUTION
If the engine still fails to work, check the engine oil level first before go to other check items.
Operating on Highlands
On highlands, the standard mixture ratio is relatively too big so the engine performance may be impaired
while the fuel consumption may increase. This problem can be solved as follows: replace the main jet of carburetor
with a smaller one, then, adjust the idly screw. If always using on highlands with a height above sea level of 1830
meters, ask your dealer for doing the job.
The engine power will decrease by about 3.5% with every 305 meters up in height; even the proper main jet is used.
The output would be much lower if not adjust the jet.
CAUTION
The engine equipped with the main jet applicable to highlands may be damaged seriously in area below specified
altitude, because its mixture ratio is too thin, output drops and the engine overheats for operation in low altitude
area. In the case, ask your dealer to recover the engine to its normal technical status.
15
STOP
In an emergency, push the engine switch to “OFF” to stall the engine. Stop it in normal in the following sequence:
1. Push right the throttle valve lever to the bottom (Pic. 12). 2. Push the engine switch to “OFF” (Pic. 13)
(Pic. 12) (Pic. 13)
3. Set the fuel switch to “OFF” (Pic. 14)
(Pic. 14)
16
EXHAUST CONTROL SYSTEM
With the engine running, carbon monoxide, oxide of nitrogen and hydrocarbon will produce, and in certain
conditions, oxide of nitrogen and hydrocarbon will react chemically each other to make smoke while carbon
monoxide is toxic, so exhaust control of them is very important. The company decreases the exhaust emissions by
introducing poor-fuel carburetors and other devices into the engine to solve the problem.
To keep the exhaust of your engine within the standard exhaust emission values, pay attention to the following:
I. MAINTENANCE
Maintain the engine periodically in accordance with the Maintenance Schedule in the manual. The maintenance
schedule is made out on the base of normal use in normal conditions, if using under heavy load, dusty or wet
circumstances or in high temperature, more frequents maintenance will be necessary.
II. REPLACEMENT OF PARTS
We recommend that you should choose such parts, which are manufactured by our Co. or equivalent to these in
quality as replacement ones. Replacement without so high quality may impair the exhaust control system in
effectiveness.
III. MODIFYING
Modifying the exhaust control system may make actual exhaust emissions exceeding statutory limit values. Illegal
modification is as follows:
1.Dismantle or modify any part of air inlet or outlet system.
2.Modify or take off speed-adjusting connection device or speed adjustment device to result in the engine’s running
17
or outside the set parameters.
Ⅳ.PROBLEMS AFFECTING EXHAUST EMISSIOS
1. Difficult starting or difficult stopping.
2.Unstable idling.
3.Give off black smoke or consume too much fuel.
4.Poor ignition sparks or sparks returned.
5.Ignition is too advanced.
Once you find any of above problems, contact your dealer for help.
