COOLING SYSTEM SPARKING PLUG

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).

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 operation, and subsequently after every 50 hours of operation 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.

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 often 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 carburettor (fig. 12). Take out the foam plastic filter element and wash it in liquid detergent and water. Dry the filter element. Pour a little oil on the filter element 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.

Never remove the spark plug or the ignition 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 0.7-0.8 mm (fig. 14).

Change the sparking plug if the electrodes are excessively burnt or if the plug is damaged. The recommendations of the engine manufacturers are as follows:

Champion J19LM (RJ19LM) or another equivalent spark plug ought to be used in Briggs & Stratton engines.

ADJUSTMENT OF THE CLUTCH WIRE

If the drive cannot be engaged or disengaged, it may be that the clutch wire needs adjusting.

Adjust as follows:

1.Remove the transmission cover by unscrewing the screws S (fig. 9).

2.When the clutch loop is released it should be possible to roll the mower without any resistance. If this is not the case, loosen the locking nut U and screw in the nipple T until the mower can be moved backwards (fig. 15).

3. When the clutch loop is pressed in approx. 2 cm (position 1) there should be

some resistance when moving

the mower backwards. With

the clutch loop fully pressed

in (position 2) it should not be

possible to pull the mower backwards. Loosen the locking nut U and screw out the nipple T until this position is achieved.

4. Finally tighten the locking nut U.
