Checking the oil 

Caution.

 The lawn mower is shipped without oil. Do not 

start your lawn mower before ensuring it has been filled 

with the right amount of correct grade oil. Refer to the 

oil recommendations section of the Briggs & Stratton 

instruction manual for this information.  
1. Move the lawn mower to 

a level surface and clean 

around the oil filter cap (8). 

2. Remove the oil filter cap 

with dipstick and wipe it 

with a clean cloth. Replace it 

and retighten the cap. 

3. Remove the dipstick again 

and check the oil level, the 

oil should be at the full 

mark. 

4. If oil is required add it slowly 

(the oil capacity is about 0.6 

litre), do not over fill. 

5. Retighten the oil filter cap 

firmly before starting the 

engine. 

Starting the engine 

Note.

 Before starting the mower check the oil and fuel 

levels. 
1. Move the throttle lever (3) to the cold start position. 

2. Push the primer bulb firmly 5 times (for initial starting) 

or 3 times (for engine starting there after). 

3. Pull the recoil starter (9) lightly until you feel resistance 

then pull quickly until the engine starts. Do not pull the 

cord with a jerk or release it until fully rewound. 

4. Once the lawn mower has started and warmed up move 

the throttle lever to the Run position.

Stopping the engine

To stop the engine, move the throttle lever (3) to the 

stop position. 

Mowing advice 

1. It is recommended to use the fast throttle setting and 

keep the engine running at maximum speed. This will 

deliver the best cut. If the speed of the engine slows 

this could indicate the mower is being overloaded, by 

trying to cut to much grass. Try mowing a narrower 

strip, mowing slower or raise the cutting height. 

2. Sharp blades cut cleanly and efficiently, if the blade is 

dull it will tear the grass. This will result in the ends 

turning brown. When the blades no longer cut cleanly 

either sharpen them or replace them.
