ENGLISH
Clean the silencer and the surrounding area regularly to remove grass, dirt and flammable waste products.
NOTE! Clean under the transmission casing once or twice a year. Set the lowest cutting height. Undo the screws and remove the transmission casing (fig. 14). Clean with brush or compressed air.
Once every season, the drive wheels should be cleaned internally. Remove the wheel cap, screw, washer and wheel. Clean the gear wheel and the wheel’s gear rim of grass and dirt using a brush or compressed air (fig. 15). Replace the wheel.
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.
LUBRICATION
Set the lowest cutting height. Remove the screws and dismantle the transmission casing. Lubricate the drive shaft at the glide bearings with oil/oil spray at least once per season (fig. 16).
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 oper- ation, and subsequently every 50 hours of opera- tion 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
AIR FILTER
A dirty and blocked air filter reduces the engine output and increases engine wear.
Briggs & Stratton LS 40/45: Carefully remove the air cleaner so that no dirt falls down into the carburettor (fig. 17). Remove the foam filter and wash it in liquid detergent and water. Dry the filter. Pour a little oil on the filter and squeeze it in. Re- assemble the air cleaner.
Wash the filter every three months or after every 25 hours of use, whichever occurs first. More fre- quently if the engine is working on dusty ground.
Briggs & Stratton ES 45: Undo the screw and fold down the cover of the air cleaner. Carefully re- move the filter cartridge (fig. 18). 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 often if the lawnmower is used on dusty ground.
Honda: Remove the cover and take out the filter (fig. 19). 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
Clean the air filter after every 25 hours of opera- tion or once a season. More frequently if the en- gine 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 instru- ment.
Clean the spark plug regularly (every 100 hours of operation). Use a wire brush for cleaning. Set the correct spark gap (fig. 20).
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
Honda: BPR6ES (NGK), Spark gap
BATTERY (Multiclip 46 SE)
The electrolyte in the battery is toxic and corrosive. It can cause serious cor- rosion damage etc. Avoid all contact with skin, eyes and clothing.
In normal use during the season, the battery is charged by the engine. If the engine cannot be started with the ignition key, it may be because the
