STOP! 

Do not start the engine before putting 500ml of SAE 30 oil into the engine. 
Failure to do so will result in irreparable damage to the engine and invalidate 
your warranty.

START/STOP the engine

WARNING:

 The blade begins to rotate as soon as the engine is started.

NOTE:

 Do not operate the machine in enclosed or poorly ventilated areas as the 

exhaust gas contains toxic substance. Keep hands, feet, hair and clothing away from 
all the moving parts of the machine. The exhaust and other parts of the machine will 
become hot during use. Make sure that the blade is securely fastened before starting 
the engine.

NOTE:

 to start the engine, make sure that the spark plug boot is located on the plug 

and the machine is filled with sufficient oil and petrol. When starting a cold engine, 
press down the primer fully 3-5 times.(see Fig.11)

WARNING! 

Too much presses on primer may cause engine flooded when starting a 

warm engine, the primer does not need to be used. If the engine stops due to a lack 
of petrol, refill and press down the primer 3~5 times.

1.  Stand behind the mower. Pull the engine Start/stop lever toward upper handle with one 

hand. And place the other hand on the starter handle.

2.  Pull the starter handle out approx. 10-15cm until you feel a resistance and then start the 

engine with a sharp pull.(see Fig.12)

Mowing

WARNING!

 Always observe the strictest safety procedures when using the 

lawnmower. Carefully read the safety instructions of this manual before using the 
lawnmower.

WARNING!

 Never open the safety flap when the grass bag has been detached (to be 

emptied). And the engine is still running. The rotating blade can cause serious injuries!

1.  Select your required setting.
2.  Start the engine and allow it run.
3.  Keep a firm grip on the upper handle with engine stop/start lever, and push it to start 

mowing.

Good practice advice

1.  Walk, never run with the mower, be very careful when mowing uneven or rough ground.
2.  Mow across slopes, never up and down.
3.  Be careful when changing the direction of the mower on a slope.
4.  Do not mow excessively steep slopes.
5.  The best result will be achieved if the grass is dry. Wet grass will tend to clog the blade 

and the grass collection system.

6.  Grass grows at different rates at different time of the year. Never use the lowest cutting 

height for the first cut of the season or in drought conditions.

7.  Only about one third of the grass height should be cut.
