Fig.38 Engine Stop Throttle Control Position
Engine description
See the separate engine manual for engine maintenance instructions.
Maintain engine oil as described in the engine manual that came with the unit.
Please read and follow the instructions carefully.
Under normal conditions, please maintain the air filter in accordance with the separate engine manual; clean it every few hours under extremely dusty
conditions. When the engine is not performing well or after being invaded by water, the air filter and carburetor should normally be repaired.
To service the air filter, refer to the engine manual supplied with the unit.
It is recommended to replace the spark plug or check the spark plug at the beginning of each machine season. Please refer to the engine manual for
the correct plug type and clearance specifications.
Clean the engine regularly with a cloth or brush. Keep the cooling system (blower housing area) clean to allow proper air circulation, which is critical to
engine performance and life. Always remove all grass, dirt and combustible waste from the muffler area.

17
Machine cleaning and storage
Proper cleaning and storage are critical to keeping your machine trouble-free and in good condition.
1）Cleaning
1. Cleaning machine
Cleaning engine
●Manually clean the engine and take care to prevent water from entering
the air filter.
- Using garden hoses or pressure washers can cause water to enter the
air filter. The water in the air filter will soak the filter and enter the
carburetor or engine and cause damage.
- Water on a hot engine can cause engine damage. If the engine is
already running, let it cool for at least half an hour before cleaning.
●Make sure the fuel valve is in the closed position before cleaning the
housing of the machine platform. Disconnect the spark plug cap. Turn
the machine sideways so that the air filter is facing up. This will help
prevent fuel leakage and hard start caused by carburetor overflow.
●Wear thick gloves to protect your hands from the blade.
Cleaning collection bag
●Remove the collection bag from the machine and wash it with a garden
hose or high pressure cleaning equipment. Allow the bag to dry
completely before storing.
2. After cleaning the machine, wipe all accessible surfaces.
3. Start the machine outdoors and run it until it reaches the normal
operating temperature to evaporate the water remaining on the
engine.
4. Stop the engine and allow it to cool.
5. After the machine is clean and dry, cover the damaged paint
surface and any other areas that may rust with a thin oil film.
Lubricate the control cable with a silicone spray lubricant.
2）Storage
●The following steps should be taken to prepare the machine for storage.
1. Empty the fuel tank after use in the last quarter.
a）Empty the fuel tank with a suction pump.
Be careful! Do not discharge petrol in a closed room or near an open flame. Do not smoke! This can cause an explosion or fire.
b）Start the engine and let it run until it runs out of all remaining petrol.
c）Remove the spark plug. Inject 20ml of oil into the combustion chamber using a syringe. Pull the starter cord to evenly distribute the oil in the
combustion chamber.
2. Clean and lubricate the machine carefully as described in the Lubrication Instructions above.
3. Gently apply the rust inhibitor to the impeller and exposed metal parts to avoid corrosion.
4. Store the machine in a dry, clean, frost-proof place away from unauthorized personnel
Be careful! The engine must be completely cooled before storing the machine.
Machine maintenance instructions
1）The importance of proper maintenance
●Proper maintenance is critical to safe, economical and trouble-free operation; it also helps reduce air pollution.
Improper maintenance or failure to correct problems prior to operation can result in serious injury or death.
●Always follow the maintenance recommendations and schedules in this instruction manual.
To help you properly maintain your machine, the following pages include maintenance plans, routine inspection procedures, and simple maintenance
procedures using basic hand tools. Other maintenance tasks that are more difficult or require special tools are best handled by professionals, usually
by our technical staff or other qualified mechanics.
The maintenance plan is for normal operating conditions. If you operate the machine under harsh conditions, such as continuous high load or high
temperature operation, or in unusually humid temperatures, consult your service dealer for advice that is appropriate for your individual needs and use.
Maintenance, replacement or repair of the emission control devices and systems can be performed by any engine service facility or
individual using components that meet the EPA standards in the "Certification".
2）Maintenance safety
We cannot warn you of the dangers that can arise when performing maintenance. Only you can decide if you should perform the given situation.
3）Safety instructions

18
Make sure the engine is off before starting any maintenance or repairs.
4）Routine maintenance
1. Oil maintenance
Before each use of the machine, check the oil level to see if it is between the upper and lower marks on the oil gauge (see Fig 39-2). The new machine
will take approximately 5 hours to achieve optimal performance. After the running-in period, please replace the oil. After this the oil should be replaced
after 25 hours of use, and changed periodically according to the instructions.
The oil change should be carried out after the engine is hot. Do not carry out an oil change with the engine running. If too much oil is added you may
see the following symptoms: black smoke, no power (excessive cylinder carbon deposit, small spark plug clearance). Engine overheating. If not
enough oil is used you may experience the following: the engine is noisy, the piston ring accelerates wear and damage, and piston seizes or partially
seizes, causing serious damage to the engine. When changing the oil, the machine must be tilted in the direction of the oil port, you can pour it out and
replace it with new oil, but you can't tilt it to the other side. Otherwise, the oil will flow into the carburetor, causing damage to the carburetor.
Fig.39-1 Take out the dipstick Fig.39-2 Measuring oil level
2. Air filter maintenance
Check the air filter for dirt before and after each use. If it is too dirty, it will
cause the engine to start hard, black smoke, and no power. If the filter
element is paper, remove the filter element and remove the dust
attached to it; If the filter element is made of sponge, after cleaning with
petrol, apply some lubricating oil on the filter element to keep the filter
element moist, which is more conducive to dust absorption. However,the
other layer surrounded by the sponge cannot be washed with water.
After washing, it will cause the pores to close and affect the engine work
(the inner layer is made of paper). When cleaning, use an air gun to blow
it clean.
Fig.40-1 Open the air filter side cover
Fig.40-2 Take out the filter
3. Radiator maintenance
The main function of the radiator is to eliminate noise and heat. When
the machine is working, the sundries may be covered on the heat sink,
affecting its heat dissipation function. In severe cases, the engine may
be damaged. Therefore, after each use of the machine, the debris on the
heat sink should be carefully cleaned.
4. Fuel maintenance
Every time the fuel is exhausted, the machine should be allowed to rest
for ten minutes before refueling. Otherwise, the fuel will be on fire due to
the high temperature of the machine. When refueling, please add the
same amount of fuel according to the fuel capacity. if you add too much
oil, it will block the vent hole on the oil cover, causing the oil level to be
free from pressure and unable to supply oil to the engine.

Do not screw in the dipstick when checking the oil level
