PowerBoost function

When the product cuts long or wet grass, the motor
automatically increases rpm. To save battery time, the
motor goes back to standard mode automatically when
the PowerBoost function is not necessary.
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. 20)
2. Push the ON/OFF button on the control panel. All
LED lights and symbols on the display go out. (Fig.
57)
3. Remove the safety key from the safety lock and put
it in the safety key holder.
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.
To cut grass without a grass catcher or
mulch plug attached
1. Lift up the rear cover and remove the grass catcher.
2. If a mulch plug and a mulch blade are attached,
remove them.
3. Close the rear cover before you operate the product.
