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: 

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. 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, refill 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 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. 

(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 
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.

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 filled 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 classified 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 
first 5 hours of use.

Check the engine oil level with the engine stopped and the mower on a level surface. 

1.  Remove the oil filler dipstick and wipe oil from it with a clean cloth. 
2.  Insert the dipstick into the oil filler 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, fill to the upper level with the 
recommended oil (SAE 30 or equivalent). Do not overfill. Wipe away any spilt oil. (Fig. I)

4.  Before using for the first time, add 0.5 litres of oil (SAE 30). 

Filling with engine fuel (Fig. J)

WARNING! 

Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow 
flames or sparks in the area where the engine is refueled or where petrol is stored. 
Avoid repeated or prolonged contact with skin or inhalation of vapour. 

CAUTION! 

Petrol is highly flammable and extreme caution must be taken when handling or 
working with it. Keep out of reach of children.

1.  Clean the area around the petrol filler cap before removing the cap. Check the fuel level. 
2.  Refill the tank if the fuel level is low. 
3.  Always use clean, fresh unleaded petrol and purchase fuel in quantities that can be used 

within 30 days. 

Never mix oil with petrol. 
To allow for expansion, carefully refuel and avoid overfilling or spillage. There should be no 
fuel in the filler neck. 
Clean up any overflow or splashes of petrol before starting the engine. 
Tighten the filler cap after filling, finger tight only.
