Cleaning
1. To ensure long life and good performance of the machine, it’s important to keep the
machine clean and well lubricated. Make sure the chute is clean and under the deck is
cleared from wet debris. (See also short term storage).
2. Do not allow grass cuttings and other debris to become dry and hard on any of the
mower surfaces, as this will directly affect the cutting and grass collection performance.
Make sure that the underside of the lawnmower deck is clean and clear.
3. Never clean the lawnmower with a water jet or high-pressure cleaner. The engine must
remain dry. Do not use aggressive cleaning agents or solvents, such as cold degreasers
or petroleum ether.
Cleaning or replacing the air filter
WARNING!
Never run the engine without the air filter element installed:
1. Loosen the fastener that holds the cover.
2. Open the cover and remove the filter.
3. To loosen debris, gently tap the filter on a hard surface. If the filter is excessively dirty,
replace with a new filter.
4. Install the filter.
5. Install the cover tabs into the slots.
6. Close the cover and secure with the fastener.
Cleaning or replacing the spark plug
1. Once the engine has cooled, pull off the spark plug boot with a twist. Remove the spark
plug using the socket spanner supplied.
2. Clean the plug with a wire brush.
3. Using a feeler gauge, set the gap to 0.51mm.
4. Install the spark plug carefully by hand to avoid cross-threading.
5. After the spark plug is seated, tighten with the spanner to compress the washer.
Changing the oil
Tilt the lawnmower towards the oil filler, have a container ready to catch the oil, and remove
the dipstick. Once the oil has been emptied, wipe clean any spillages.
Refill with 470ml SAE 30 oil or equivalent, i.e. SAE 5W/30, SAE 10W/30). When the dipstick
is rested on the filler pipe, the oil level must be between the min. and max. marks on the
dipstick.
