Mowing Tips

WARNING: 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.

WARNING: 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.
1. Release bail handle to turn mower “OFF” when crossing
any gravel area (stones can be thrown by theblade).
2. Set mower at highest cutting height when mowing
in rough ground or in tall weeds. Removing too much
grass at one time can cause the motor to be overloaded
and to stop. Refer toTroubleshooting.
3. If a grass collection bag
12
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, remove the safety key and battery pack. 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.
4. If mower should start to vibrate abnormally, release bail
handle to turn mower off, remove the safety key and
battery pack. Check immediately for cause. Vibration
is a warning of trouble. Do not operate mower until a
service check has been made. Refer to troubleshooting
section inthismanual.
5. For best cutting results, keep blade sharpened
andbalanced.
6. Inspect and thoroughly clean mower after each use as a
deck with caked grass will degradeperformance.
7. ALWAYS RELEASE BAIL HANDLE TO TURN MOWER
OFF, REMOVE SAFETY KEY AND BATTERY PACK
WHEN LEAVING IT UNATTENDED EVEN FOR A
SHORT PERIOD OFTIME.
The following suggestions will help you to obtain
optimum run time from your cordless mower:
• Slow down in areas where the grass is especially
long orthick.
• Avoid mowing when the grass is wet from rain or
dew-soaked.
• Cut your lawn frequently, especially during high
growthperiods.
NOTE: It is recommended that your mower be
recharged after use to prolong the battery life.
Frequent charging will not harm your battery, and
will ensure that the battery is fully charged and ready
for its next use. Storing battery not fully charged will
shorten batterylife.
