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 to 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 authorised 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 Operating Manual.
