wet grass. For effective mowing do not cut wet grass because it tends to stick to the underside of 
the deck preventing proper mowing of the grass clippings. Cut no more than 1/3 the length of the 
grass. The recommended cut for mowing is 1/3 the length of the grass. Ground speed will need to 
be adjusted so the clippings can be dispersed evenly into the lawn. For especially heavy cutting in 
thick grass it may be necessary to use one of the slowest speeds in order to get a clean well mowed 
cut. When mowing long grass you may have to cut the lawn in two passes, lowering the blade ano-
ther 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. Pull out the mains plug, 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. 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 balan-
ce 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

      WARNING! 

Disconnect the electric cord from the power supply.

      WARNING! 

Protect hands by using heavy gloves or a rag to grasp the cutting blades when 

replace the blade.
