Setting the cutting height (Fig. K)
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 5 positions for the desired cutting height.
3. Return the lever into the securing plate.
NOTE:

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. L)
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, rell and press down the primer 3-5 times.
2. Start/stop bar activation
Pull the start/stop bar towards you and hold it in place.
(Fig. M)
3. Pull cord handle
With the right hand, slowly but rmly 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.
(Fig. M)
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
ooded with excess fuel.
Use the following procedure to clean and start a ooded 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.
Filling with engine oil (Fig. I)
IMPORTANT!
The following procedures and adjustments must be performed
before the engine is started. Do not attempt to make any of these adjustments
while the engine is running.
This engine is shipped without oil or petrol, any oil residue is from testing prior to shipping.
The engine must be lled with the correct grade of oil and petrol before starting the engine.
Running the engine with a low oil level will cause irreparable engine damage.
Always use high-quality detergent oil classied SAE 30 oil (or equivalent, e.g. 10W 30,
often termed as 4-stroke lawn mower oil). Only use additives recommended by the engine
manufacturer. To prolong the life of your engine, it is important that the oil is changed after the
rst 5 hours of use.
Check the engine oil level with the engine stopped and the mower on a level surface.
1. Remove the oil ller dipstick and wipe oil from it with a clean cloth.
2. Insert the dipstick into the oil ller neck, and screw it in.
3. Then remove the dipstick and check the oil level. The oil level must be between the Min.
and Max. marks on the dipstick. If near the lower level, ll to the upper level with the
recommended oil (SAE 30 or equivalent). Do not overll. Wipe away any spilt oil. (Fig. I)
4. Before using for the rst time, add 0.5 litres of oil (SAE 30).
