139CC 40CM PETROL LAWN MOWER   

 EN

CAUTION: Do not touch rotating blades.

For the first mow of the season, a high cutting 

adjustment should be selected.

The lawnmower can be set to 8 cutting heights 

between 25mm and 75mm. For this purpose, 

move  the cutting height adjustment lever (14) 

outwards then adjusted to the preferred position.

9. MOWING 

Always observe the strictest safety 

procedures when using the lawnmower. 

Carefully read the safety instructions of this 

manual before using the lawn mower.

Start the engine and allow it run. See “Starting 

the engine”.

When it is time to start mowing, move the 

throttle lever to its 

FAST

 position (See Fig. G).

To stop the engine, move the throttle lever to the 

STOP

 position (See Fig. G).

Keep a firm grip on the upper handle and walk, 

never run with the mower, be very careful when 

mowing uneven or rough ground. Mow across 

slopes, never up and down. Be careful when 

changing the direction of the mower on a slope. 

Do not use the mower on a steep slope of more 

than 20°.

The best results will be achieved if the grass is 

dry. Wet grass will tend to clog the blade and 

the grass collection system. Grass grows at 

different rates at different times of the year. 

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.

If the lawnmower will not collect the cuttings 

efficiently, the grass discharge chute may be 

blocked. The grass catcher may be full, or the 

underside of the mower deck may be clogged.

10. EMPTY/ATTACH THE GRASS CATCHER

As soon as you see mown grass debris on the 

lawn, the grass catcher needs to be emptied.

IMPORTANT! Before you remove the grass 

catcher, move the throttle lever to the STOP 

position and wait the blade system reaches a 

standstill.

1)  To remove the grass catcher, raise the safety 

flap with one hand and remove the grass 

catcher using its handle with your other 

hand.

2)  To maintain safety, the safety flap will close 

back to cover the rear discharge opening, 

when you release the flap.

3)  Empty the grass clippings from the grass 

catcher into the appropriate bin. Check with 

your local council for more information. Refit 

glass catcher as above instruction.

4)  If any grass clippings are caught in the 

discharge chute, clean it using a broom or 

similar extension. 

5)  Do not remove grass debris in the mower 

casing or on/around the blades by hand or 

with your feet. Instead use suitable tools 

such as a brush or broom.

6)  To ensure that the grass clippings can be 

blown into glass catcher, the discharge chute 

and the inside of the mower deck must be 

cleared of any blockage.

11. REPLACING THE BLADES (See Fig. J)

Always check the sharpness of blades before 

cutting grass. If the blades are worn excessively 

and becomes pitted or blunt they should be 

replaced. The sharpness of the blade will affect 

the performance of the lawn mower.

For safety reasons we recommend that the 

blades will only be changed by persons 

qualified and authorized to do so.

WARNING! Before replacing the blades, 

ensure that the engine is switched off 

and the spark plug cap is disconnected and 

moved away from the spark plug.

1)  You will need garden gloves (not provided) 

and a spanner/wrench (not provided) to 

remove the blade holder.

2)  Hold the blade holder and unscrew the blade 

bolt counterclockwise using a spanner /

wrench. Remove the blade bolt, retaining 

washer and the blade.

3)  Fit a new blade, locate the blade holder on 

the two studs on the blade flange and then 

refit the washer and bolt. Make sure the blade 

is correctly located, then firmly tighten the 

bolt. Do not over tighten (Do not less than 45 

N.m tight torque).

The upturned flute of the blade must face the 

motor side of the deck so the blades can throw 

the grass into the catcher. (Do not less than 45 

N.m tight torque).

Always handle the blade with care-sharp
