• Release bail handle
8
to turn mower “OFF” when crossing
any gravel area (stones can be thrown by theblades).
• 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.
• If a grass collection bag
22
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
6
and battery packs
26
. Remove the grass
collection bag
22
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. Reinstall the grass
collection bag
22
.
• If mower should start to vibrate abnormally, release bail
handle to turn mower off, remove the safety key and battery
packs. Immediately check for cause. Vibration is a warning
of trouble. Do not operate the mower until a service check
has beenmade.
• For best cutting results, keep blades sharpened
andbalanced.
• Inspect and thoroughly clean mower after each use. A deck
with caked grass will degradeperformance.
• Always release the bail handle to turn mower off, remove
safety key and battery packs when leaving it unattended
even for a short period oftime.
The following suggestions will help you to obtain
optimum runtime from your cordless mower:
• Slow down your cutting pace 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 both of your battery packs be
recharged after each use to prolong the battery life. Frequent
charging will not harm your battery packs, and will ensure that the
battery packs are fully charged and ready for their next use.
NOTE: Storing the battery packs not fully charged will
shortentheirlife.
