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 pull the mower backwards 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 (posi- tion 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 lock- ing nut U and screw out the nipple T until this position is achieved.

4. Finally tighten the locking nut U.

CHANGING BLADES

Use protective gloves to prevent cuts when changing blades/knifeblades.

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 screw (fig. 16). Fit the new blade so that the stamped STIGA log- otype is turned facing the blade attachment (and not facing the grass). Refit the washer and screw. Tighten the screw fully to a torque of 40 Nm.

When replacing the blade, the blade screw 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 screw, 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 machine.

SHARPENING OF THE BLADES

Sharpening of the blades must be done by wet method grinding, using a whetstone or a grind- stone.

For the sake of safety, the blades 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.

Tip up the mower and screw out the sparking plug. Pour a teaspoon of engine oil in the sparking plug hole. Pull out the starting handle slowly so that the oil is distributed in the cylinder. Screw in the sparking plug.

Thoroughly clean the mower and store it indoors in a dry place.
