LUBRICATING DRIVE SHAFT
Once per season, the wedge on the drive shaft
should be greased. Remove the wheel (wheel cap,
screw and washer).
Then remove the circlip and washer so that the
gear wheel can be removed from the shaft.
Lubricate the wedge with universal grease.
Reinstall the wedge (the wedge is installed differ-
ently on the right and left side, fig. 11 - 12). Install
the gear wheel so that the «L» faces out on the left
side and the «R» faces out on the right side
(machine viewed from the rear).
ADJUSTING CLUTCH CABLE
If the drive does not engage when the clutch loop
is pressed against the handle, or if the lawnmower
feels cumbersome or slow, this may be because
the clutch in the transmission is slipping.
To rectify this situation, adjust the clutch cable as
follows (with the engine off):
1. When the clutch loop is released, it should be
possible to push the mower backwards without
any resistance. If this is not the case, screw in
the nipple T until the mower can be pushed (fig.
13).
2. When the clutch loop is pressed in approx. 2 cm
(position 1), there should be some resistance
when pushing the lawnmower. With the clutch
loop fully pressed in (position 2) it should not be
possible to push the mower. Unscrew the nipple
T until this position is achieved.
CHANGING BLADES
To replace the blade, undo the screw (fig. 14).
Fit the new blade so that the stamped logo is
turned up facing the blade holder (not facing the
grass).
Reinstall as illustrated. Tighten the screw properly.
Tightening torque 40 Nm.
When replacing the blade, the blade screw should
also be replaced.
SHARPENING THE BLADES
Sharpening of the blades must be done by wet
method grinding, using a whetstone or a grind-
stone.
For safety reasons, the blades should not be
sharpened on an emery wheel. A very high temper-
ature could cause the blades to become brittle.
STORAGE
The same petrol must not remain in the tank for
more than one month.
Thoroughly clean the mower and store it indoors in
a dry place.
SERVICING
Genuine spare parts are supplied by service work-
shops and by many dealers.
We recommend that you take the machine to an
authorised service station for annual servicing,
maintenance and inspection of safety equipment.
For service and spare parts, please contact the
dealer where the machine was purchased.
