Setting the cutting height (Fig. L)

WARNING!

The blade can cause serious injury. Before adjusting the mower height, stop the 
engine and wait for the mower blade to come to a complete stop.

1.  Pull the lever towards the wheel, then move it forward or backward to adjust the cutting 

height. 

2.  Move it to any one of the 7 positions for the desired cutting height. 
3.  Return the lever into the securing plate. 

NOTE: 

Never use the lowest cutting height for the first cut of the season or in drought 

conditions. Only about one third of the grass height should be cut at this time.

Starting the engine

WARNING! 

Do not operate the machine in enclosed or poorly-ventilated areas, as the exhaust 
gas contains toxic substances. 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.

1.  When starting a cold engine, press down the primer fully 3-5 times. 

(Fig. M)

Pressing the primer button too many times could cause the engine to flood.
NOTE: 

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.

2.  Start/stop bar activation

Pull the start/stop bar towards you. 

(Fig. N)

3.  Pull cord handle

With the right hand, slowly but firmly pull the starter handle and rope from the pull cord 
guide until you feel resistance, then pull briskly. If the engine fails to start after three 
pulls, repeat the start process. When the engine starts, return the starter rope to the rope 
guide gently.

To stop, release stop/start bar

Failure to start

If the engine won’t start after you have operated the starter several times, the engine may be 
flooded with excess fuel.
Use the following procedure to clean and start a flooded engine:
A. Release the stop/start bar.
B. Remove the spark plug, dry it, and then reinstall it.
Install the spark plug carefully by hand, to avoid cross-threading. After the plug is seated, 
tighten it 1/8 to 1/4 turns with the socket spanner to compress the washer.
C. Pull the stop/start bar towards the upper handle.
D. Operate the starter, as described above.
