Maintenance

Before you do
WARNING:

seconds. Wait for a minimum of 15 seconds
before you do a check of the cutting cover.
WARNING:
cutting cover, release the motor brake
handle, remove the safety key, remove
the batteries and wait for a minimum of
5 seconds. There is a risk of injury if
the obstacle is removed and the product
accidentally starts.
To stop the product
The product stops automatically if you do not operate it
for 3 minutes.
1. Release the motor brake handle to stop the motor.
(Fig. 18)
2. Push the ON/OFF button on the control panel. All
LED lights and symbols on the display go out. (Fig.

3. Remove the safety key from the safety lock and put

To get a good result
• Always use a sharp blade. A blunt blade gives an
irregular result and the cut surface of the grass
becomes yellow. A sharp blade also uses less
energy than a blunt blade.
• Do not cut more than ⅓ of the length of the grass.
Cut first with the cutting height set high. Examine the
result and lower the cutting height to an applicable
level. If the grass is very long, drive slowly and cut 2
times if necessary.
• Cut in different directions each time to prevent
stripes in the lawn.
• Keep the cutting cover clean. Buildup from grass
and dirt on the inner side of the cutting cover can
decrease the cutting result. Refer to
product on page 17 .
