SAFETY KEY

DANGER :

In order to prevent accidental start-up or unauthorized use of your
Cordless Mower, a removable Safety Key D-6 has been incorporated
into the design of your mower. The mower will be completely disabled
when the Safety Key has been removed from the mower. With the
Safety Key removed, you will have access to the charger receptacle D-8. 

NOTE: THE SAFETY KEY HAS A HOLE IN THE CENTER TO
ALLOW FOR STORAGE ON A NAIL, OUT OF THE REACH OF
CHILDREN. DO NOT TETHER SAFETY KEY TO MOWER.

DANGER:

ROTATING BLADES CAN CAUSE SERIOUS

American National Standards Institute, and the U.S. Consumer Product
Safety Commission. The Blade turns when the motor is running.

SAFETY SHIELD AND REAR DOOR

This safety shield I-1 is designed to minimize the throwing of stones or
other objects by the mower blade backward from under the mower
deck. The shield, along with the rear door I-2, minimizes the possibility
of accidental foot contact with the blade. DO NOT operate mower 
without the safety shield and rear door in place.

DANGER:

Sharp moving blade

. For your own safety DO NOT

use this mower without either the grass catcher or mulch insert in
operating position as serious injury could result.

DANGER:

Sharp moving blade

. Do not operate the mower if the

rear door is not closed under spring tension as serious injury could
result. Take your mower to the nearest service center for repair.

MOWING TIPS

NOTE: ALWAYS INSPECT AREA WHERE MOWER IS TO BE USED
AND REMOVE ALL STONES, STICKS, WIRE, BONES AND OTHER
DEBRIS WHICH MIGHT BE THROWN BY THE ROTATING BLADE.

1. Mow across the face of slopes, never up-and-down. Exercise

extreme caution when changing direction on slopes. Do not mow
excessively steep slopes. Always maintain good footing.

2. Release bail handle to turn mower “OFF” when crossing any 

gravel area (stones can be thrown by the blade).

3. Set mower at highest cutting height when mowing in rough ground

or in tall weeds. Removing too much grass at one time can cause
circuit breaker to trip, which stops mower. Refer to troubleshooting
guide.

4.  If a grass catcher is used during the fast growing season, the grass

may tend to clog up at the discharge opening. Release bail handle
to turn mower off and remove the safety key. Remove the catcher
and shake the grass down to the back end of the bag. Also clean
out any grass or debris which may be packed around the discharge
opening. Replace the grass catcher. 

5. If mower should start to vibrate abnormally, release bail handle to

turn mower off and remove safety key. Check immediately for
cause. Vibration is a warning of trouble. Do not operate mower until
a service check has been made. Refer to troubleshooting guide in
manual.

6.

ALWAYS RELEASE BAIL HANDLE TO TURN MOWER OFF AND
REMOVE SAFETY KEY WHEN LEAVING IT UNATTENDED
EVEN FOR A SHORT PERIOD OF TIME.
