General Troubleshooting

CAUTION!

 Always switch off the engine and pull the ignition cable before starting any inspection 

or adjustment work.

CAUTION!

 If, after making an adjustment or repair to the engine, you let it run for a few minutes, 

remember that the exhaust and other parts will get hot. Thus, do not touch parts that emanate 

heat, as these may burn you.

Maintenance 

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, 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.

Step 3 - Cleaning or Replacing Air Filter

WARNING! 

Never run the engine without the air filter element installed.

1. Loosen the fastener (A) that holds the cover (B).

2. Open the cover and remove the filter (D).
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 (F) into the slots (G).
6. Close the cover and secure with the fastener (A).
