Maintenance

ENGLISH

Do not set the cutting height so low that the blade comes into contact with uneven ground.

The mower has single-lever control for adjusting the cutting height. Pull the lever out, and set the cutting height to one of the positions best suited to your lawn (fig. 19).

No servicing may be carried out on the engine or lawnmower without first removing the spark plug cable from the spark plug.

Stop the engine and remove the spark plug cable if the mower is to be lifted, e.g. during transportation.

If the lawnmower needs to be tilted, it must be tilted so that the engine’s spark plug faces upwards. Tilt the lawnmower when the fuel tank is empty.

CLEANING

After use, the mower should be cleaned. This is particularly important on the underside of the mower casing. Rinse clean with the garden hose. The mower will then last longer and work better. High-pressure washers should not be used.

If grass has dried on to the mower casing, it can be scraped clean. If necessary, touch up the underside with paint to prevent rust damage.

Clean the silencer and the surrounding area regularly to remove grass, dirt and flammable waste products.

Remove the transmission casing by removing the screws S (fig. 20) and clean around the transmission and drive belts with a brush or compressed air once or twice a year.

The drive chain should be lubricated once per season. Remove the right-hand cover from the roller and apply a little chain spray onto the chain.

COOLING SYSTEM

Before each use, the engine’s cooling system must be cleaned. Clean the cylinder’s cooling flanges and air intake of grass remains, dirt, etc.

OIL CHANGE

Change the oil when the engine is warm and the fuel tank is empty. In order to prevent burns, take care while draining as the oil is hot.

Change the oil the first time after 5 hours of operation, and subsequently every 50 hours of operation or once a season. Remove the dipstick, tilt the mower and let the oil run out into a container. Be careful not to let any oil run on to the grass.

Fill with new oil: Use SAE 30 or SAE 10W-30 oil. The crankcase holds approx. 0.55 litres. Fill until the oil reaches the “FULL/MAX” mark on the dipstick.

AIR FILTER

A dirty and blocked air filter reduces the engine output and increases engine wear.

Briggs & Stratton (fig. 21):

Undo the screw and fold down the cover of the air cleaner. Carefully remove the filter cartridge. Knock it against a flat surface. Replace the filter cartridge with a new one if it is still dirty.

Clean the filter every three months or after every 25 hours of use, whichever occurs first. More frequently if the engine is working on dusty ground.

Honda (fig. 22): Remove the cover and take out the filter. Carefully check the filter for holes or other damage. A broken or damaged filter must be replaced.

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 operation or once a season. More frequently if the engine is working on dusty ground.

SPARK PLUG

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

Clean the spark plug regularly (every 100 hours of run time). Use a wire brush for cleaning.
