GB ENGLISH

Honda: Remove the cover and take out the filter. (fig. 13). Carefully check the filter for holes or oth- er damage. A broken or damaged filter must be re- placed.

To remove dirt, carefully knock the filter several times against a hard surface or use compressed air from the back of the filter to blow-clean. Do not try to brush the filter clean as this forces dirt down into the fibres. A very dirty filter should be replaced. Clean the air filter after every 25 hours of use or once a season. More frequently if the engine is used on dusty ground.

SPARK PLUG

Never remove the spark plug or spark plug cable when checking to see if there is a spark. Always use an approved test instrument.

Clean the spark plug regularly (every 100 hours of operation). Use a wire brush for cleaning. Set the correct spark gap (fig. 14).

Change the spark plug if the electrodes are exces- sively burnt or if the plug is damaged. The engine manufacturers’ recommendations are as follows:

Briggs & Stratton: Champion J19LM (RJ19LM), spark gap 0.76 mm.

Honda: BPR6ES (NGK).

Spark gap 0.7-0.8 mm.

CHANGING BLADES

Use protective gloves when changing blades to avoid cutting yourself.

Blunt and damaged blades tear up the grass and make the lawn unsightly after mowing. New well- sharpened blades cut off the grass. This gives a green and fresh appearance after mowing.

Always check the blades after a collision. First dis- connect the spark plug cable. If the blade system has been damaged, defective parts should be re- placed. Always use genuine spare parts.

To replace the blade, slacken the screw. Fit the new blade so that the stamped STIGA logo is turned up facing the blade holder (not facing the grass). Reinstall as illustrated. Tighten the screw properly. Tightening torque 40 Nm (fig. 15).

When replacing the blade, the blade screw should also be replaced.

The guarantee does not cover damage to the blade, blade holder or engine caused by running into ob- stacles.

When replacing the blade, blade holder and blade screw, always use genuine spare parts. Non-genu- ine spare parts can entail a risk of injury or dam- age, even if they fit the machine.

SHARPENING OF THE BLADES

Sharpening of the blades must be done by wet method grinding, using a whetstone or a grind- stone.

For safety reasons, the blades should not be sharp- ened on an emery wheel. Too high temperature could cause the blade to become brittle.

Once the blade has been sharpened, it must then be balanced to avoid vibra- tion damage.

STORAGE

WINTER STORAGE

Empty the fuel tank. Start the engine and let it run until it stops. The same petrol must not remain in the tank for more than one month.

Tip up the mower and unscrew the spark plug. Pour a tablespoon of engine oil into the spark plug hole. Pull out the starter handle slowly so that the oil is distributed in the cylinder. Screw in the spark plug.

Thoroughly clean the mower and store it indoors in a dry place.
