Step 3 - Cleaning or Replacing Air Filter
WARNING! Never run the engine without the air filter element installed.
3a Unclip the air filter cover and remove the sponge filter element.
To avoid objects falling into the air tank, replace the air filter cover. Wash the filter element in
warm soap water, rinse and allow drying naturally.
3b After cleaning, it needs to be moistened with oil then squeezed dry. The oil film in the
foam can prevent debris and dust from entering the engine.

Step 4 - 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, replace the dipstick and wipe clean any spillages.
Refill with 600ml SAE30 oil or equivalent ie SAE5W/30, SAE10W/30). When the dipstick is rested
on the filler pipe (i.e. not screwed in place), the oil level must be between the min and max marks
on the dipstick.
See "Filling with Engine Oil''. Do not overfill.
Start the engine and allow it run briefly.
Stop the engine, wait one minute and check the oil level. Top up if necessary.
NOTE! See more in Engine Manual.

Step 5 - Blades

For safety reasons you should only ever have your blade sharpened, balanced and mounted by
an authorized service workshop. For optimum results it is recommended that the blade should be
inspected once a year.
NOTE! For engine maintainance, see more details in Engine Operating Manual.
