MAINTENANCE OF THE AIR FILTER
As shown in Fig. 19
Soiled air filters reduce the engine output by restricting air to the carburetor. If the air contains a lot of dust,
the air filter should be checked more frequently.
WARNING! Never run the engine without the air filter element installed.
1. Press tabs at the top of the air filter cover and tilt away from the engine to remove the cover.
2. Remove the filter cartridge.
3. To loosen debris, gently tap the filter cartridge on a hard surface. If the filter cartridge is excessively dirty,
replace with a new one.
Note: Never clean the air filter cartridge with gas or inflammable solvents.
Clean the air filter cartridge only with compressed air or by tapping it.
4. Install the filter cartridge.
5. Close the cover and secure it properly by snapping tabs back into the correct slots at the top.
CHECK AND ADD THE ENGINE OIL
The oil needs to be changed after first 5 hours. Before each use check the oil level and add additional oil if
the level is not within the Min - Max levels.
REPLACING THE BLADE
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 be inspected once a
year.
WARNING! Before you remove the grass collection bag, stop the engine and wait until the blade
stops completely.
WARNING! You will need garden gloves (not provided) and a wrench (not provided) to remove the
blade.
NOTE! Don't invert the mower. Tip it slightly towards the oil filler pipe and reach under the deck.
