5. CHECKING BEFORE OPERATION
In order to keep a safe tiller, do daily checking.
Engine Oil Checking
1) Keep the engine in a horizontal position.
2) Unscrew the oil bolt and clean it.
3) Reinsert the oil indicator into the oil filling hole without screwing it, and then pull it out to check
the oil level.
4) If the oil does not touch the oil indicator, that means the oil is not enough, please add the engine
oil through the filling hole, but it should not beyond the top level.
5) Engine Oil: SAEIOW 30, which is general lubricant for engine.
Warning：
If the level is too low, it may cause serious damage to the engine when the engine is working
Please use clean and good quality 4-stroke engine oil. Run with other engine oil or dirty oil may
shorten the lifetime of the engine severely.
Air Filter Checking
Warning:
never run the engine without an air cleaner, or severe wear of the engine may be resulted in.
Refer to the Figure 11 to dismantle the air cleaner to check and clean the dirty part inside.
Fuel checking
The engine must apply unleaded gasoline or low-leaded gasoline. Using unleaded gasoline will
decrease the possibility of producing carbon deposit and prolong the engine’s service life.
Never use an oil gasoline mixture or dirty gasoline. Avoid getting dirty, dust or water in the fuel tank.
Fuel tank: 1.6 liters.
Warning:
Gasoline is extremely flammable and is explosive under certain conditions.
Refueling in a well-ventilated area with the engine stopped. Do not smoke and allow flames or
sparks in the area where gasoline is stored or where the fuel tank is refueled.
Do not overfill the tank. After refueling, make sure the fuel tank cap is set back securely.
Do not spill fuel when refueling.
6. OPERATION INSTRUCTION
How to start the tiller
1) Open the fuel switch. (Figure 13)
2) Push the choke lever to the CLOSE position (Figure 14)
Note: It is not necessary to push to the CLOSE position when the engine is warm or the
air temperature is high.
3) Push below switches to the “ON” position.（Refer to figure 15)
4) Pull the starting handle slowly until you feel the resistance, and then pull out it suddenly and
quickly. (refer to figure 16）
[Attention]
Send back the starting handle slowly. Or it may cause the damage of the starting equipment and the
spare parts
Please don’t pull out the starting handle when running, because it will affect the engine.
If the choke lever is on the “CLOSE” position, please turn the choke lever to the “OPEN” position
after engine runs 2 minutes. （Figure 14）

Adjust the depth of rear resistance rod by changing the hole.（refer to figure 19）
How to adjust the height of the handle
Loosen the nut and then adjust the height by moving the nut right or left. （refer to figure 20）
7. MAINTENANCE
Proper routine maintenance will prolong the lifetime of engine and tiller.
Warning
Stop the engine at the flat ground, and do not touch the hot part or moving parts to avoid injury. If
the maintenance is required with the engine running, be sure to keep good ventilation in the area.
The exhaust emissions from the engine contain toxic carbon monoxide, breathing it may result injury
and even death.
Maintenance schedule
Notice:
When it works in heavy dusty area, the air cleaner should be cleaned after 10 hours or once a day.
Please check the machine periodically upon the schedule or the working time, which expires first.
8. CHANGE ENGINE OIL
When the engine is hot, it is easy to drain out the oil completely.
- Keep the engine in a horizontal position.
- Unscrew the oil filler (bolt). (refer to figure 21)
- Place a cup under the drain plug and then screw off the drain plug to drain the oil completely.
- After draining the oil thoroughly, re- install the drain plug.
- Fill engine oil up to the mark of top limit.
- Re-install the oil filler.
Engine Oil: SAEIOW 30, which is general lubricant for engine.
Clean the air filter
If the air cleaner is jam, it will output less enough air and cause fuel consumption increase. Check
and clean it periodically.
Cleaning Period: Once 50 hours’ working.
If work in hervy dust area, check it every day or once 10 hours.
Replace: each year or 300 hours’ running
1) Remove the air cleaner housing.
2) Remove paper element，paying attention to prevent dust and foreign matter
Entering into air cleaner.
3) check,clean or replace damaged air cleaner parts.
4) Restall the air cleaner parts back.
Clean the sediment cup

Clear Spark Plug
In order to ensure the engine normal running, the gap of the spark plug must be correct and no
deposit around the spark plug.
5) Remove the spark cap
6) Clear away dirt around the spark plug base.
7) Dismantle the spark plug with a spark plug wrench.
8) Visually check the spark plug. Clean with a steel brush. If the insulator is damaged, replace the
spark plug .
9) Measure the spark plug clearance with a thickness feeler. The clearance should be 0.6~0.7mm. If
adjustment is necessary, bend the side electrode carefully.
10) Check if the spark plug gasket is in good condition.
11) Screw the spark plug to the bottom first by hand and then screw up with a spark plug wrench
and compress the gasket.
MAINTENANCE FOR LONG TERM IDLING
