cut the lawn in two passes, lowering the blade another 1/3 of the length for the second cut and perhaps
cutting in a different pattern than was used the first time. Overlapping the cut a little on each pass will also
help to clean up any stray clippings left on the lawn. The mower should always be operated at full throttle to
get the best cut and allow it to do the most effective job of mowing. Clean underside of deck. Be certain to
clean the underside of the cutting deck after each use to avoid a build-up of grass, which would prevent
proper mulching. Mowing leaves. The mowing of leaves can also be beneficial to your lawn. When mowing
leaves make sure they are dry and are not laying too thick on the lawn. Do not wait for all the leaves to be
off the trees before you mow.
WARNING: if you strike a foreign object, stop the motor. Switch off the isolator key, thoroughly inspect the
mower for any damage and repair the damage before restarting and operating the mower. Extensive vibration of the
mower during operation is an indication of damage. The unit should be promptly inspected and repaired.
8.4 GRASS CATCHER
There is a level indicator on the top of the grass catcher that shows whether the catcher is empty or full:
1. The level indicator inflates if the catcher is not full during the moving. (Fig. 12A)
2. If the catcher is full, the indicator collapses; once this happens, stop mowing immediately and empties the
catcher, make sure it is clean and ensure its meshwork is ventilated. (Fig. 12B)
IMPORTANT:
If the position of indicator opening is very dirty, the indicator will not inflate-in this case, clean the position of
indicator opening immediately.

9. BLADE
The blade is made of pressed steel. It will be necessary to reshape it frequently (with a grind wheel).
Ensure that it is always balanced (an unbalanced blade will cause dangerous vibrations). To check for
balance, insert a round rod through the central hole and support the blade horizontally. A balance blade will
remain horizontal. If the blade is not balanced the heavy end will rotate downwards. Reshape the heavy
end until the blade is currently balanced. To remove the blade (1), unscrew the blade screw (2), and
replace any parts, which are damaged.
When reassembling, make sure that the cutting edges face in the direction of the motor rotation. The blade
screw (2) must be torque to 20N.m.
WARNING: For service, replace the blade with DAYE blade:
