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.

CHANGING OIL

Change the oil when the engine is warm and the petrol tank is empty. Hot oil will run out of the engine better. Use caution when draining the hot oil, as it could cause burn injuries.

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 dip stick, 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 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.

Carefully remove the air cleaner so that no dirt falls down into the carburettor (fig. 11). 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. Re- fit the air cleaner.

Wash the filter every three months or every 25 hours running, whichever comes first, or more fre- quently if used in dusty conditions.

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 (fig. 12).

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. Spark gap 0.76 mm.

CHANGING BLADES

Use protective gloves to prevent cuts when changing the blade.

Blunt and damaged blades tear off the grass and spoil the look of the lawn after mowing. New, well sharpened blades cut the grass cleanly, so that the lawn looks green and fresh even after mowing.

Always check the blade after an impact. First dis- connect the ignition cable. If the blade system has been damaged the defective parts must be changed. Always use genuine spare parts.

To replace the blade, slacken the blade bolt. Fit the new blade so that the stamped STIGA logotype is turned facing the blade attachment (and not facing the grass). Refit the washer and blade bolt. Tighten the blade bolt fully to a torque of 40 Nm (fig. 13).

When replacing the blade, the blade bolt 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, the blade holder and blade bolt, always use original spare parts. Non- authentic spare parts could lead to the risk of per- sonal injury or damage, even if they fit the ma- chine.

SHARPENING OF THE BLADE

Sharpening of the blade must be done by wet meth- od grinding, using a whetstone or a grindstone.

For the sake of safety, the blade should not be sharpened on an emery wheel. A very high temper- ature could cause the blade to become brittle.

Once the blade has been sharpened, it must then be balanced so as to avoid vi- bration 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.
