Note that you should clean the area under the tim- ing gear casing once or twice a year. Set at the low- est mowing height. Slacken the screws and remove the timing gear casing (fig. 9). Clean with a brush or compressed air.
The inside of the drive wheels should be cleaned once a season. To clean a wheel, remove the hub cap, screw, washer, and wheels. Brush or blow the gear and the gear ring on the wheel to clean them from grass and dirt (fig. 10). Remount the wheel.
CHANGING OIL
Replace the oil when the engine is warm and the fuel tank is empty. Take care while draining as the oil is hot, this is to prevent burns.
Change the oil the first time after 5 hours of oper- ation, and subsequently after every 50 hours of op- eration or once a season. Remove the oil dipstick and allow the oil to run out into a vessel. Be careful not to let any oil run on to the grass.
BATTERY (Tornado 51 SE)
Electrolyte in the battery is toxic and corrosive. It can cause serious corrosion 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 start- ed with the starter key, it may be because the battery is 'dead'. Connect the battery charger to the terminal on the battery and put on charge for 24 hours (fig. 17). On completion of charging, connect the battery terminal to the terminal on the motor.
Note! The battery charger must not be connected to the engine terminal. The engine cannot be start- ed by using the charger as a source of power sup- ply, and the charger will be damaged.
WINTER STORAGE
Store the lawn mower for the winter with the bat- tery
COOLING SYSTEM
Before use, the engine's cooling system should be cleaned. Clean the cylinder's cooling fins and the air intake, removing any grass cuttings, dirt and the like.
LUBRICATION
Set at the lowest mowing height. Slacken the screws and remove the transmission casing (fig. 9). Lubricate the driveshaft by the plastic bushings/ slide bearings I with oil or oil spray at least once a season (fig. 11).
Fill with new oil: use oil of SAE 30 or SAE 10W- 30 quality. The crankcase holds approx. 0.6 litre. Fill until the oil reaches the “FULL/MAX” mark on the dip stick.
AIR FILTER
A dirty and blocked air filter reduces the engine output and increases engine wear.
Clean the filter every three months or after every 25 hours of use, which ever occurs first. More of- ten if the lawn mower is used on dusty ground.
Briggs & Stratton LS45: Carefully remove the air cleaner so that no dirt falls down into the carburet- tor (fig. 12). Take out the foam plastic filter ele- ment and wash it in liquid detergent and water. Dry the filter element. Pour a little oil on the filter ele- ment and squeeze it in. Refit the air cleaner.
Briggs & Stratton XTE 60: Loosen the screw and fold down the cover of the air cleaner. Carefully remove the filter cartridge (fig. 13). Knock it against a flat surface. Replace the filter cartridge with a new one if it is still dirty.
SPARKING PLUG
Never remove the spark plug or the igni- tion lead when checking to see if there is any spark, always use an approved test instrument.
Clean the sparking plug regularly (every 100 hours running). Use a wire brush for cleaning and adjust the correct spark gap 0,75 mm (fig. 14).
Change the sparking plug if the electrodes are ex- cessively burnt or if the plug is damaged. The rec- ommendations of the engine manufacturers are as follows:
Champion J19LM (RJ19LM) or another equiva- lent spark plug ought to be used in Briggs & Strat- ton engines.
