MAINTENANCE

DANGER: To reduce the risk of serious personal
injury, turn unit off and remove the safety key and
battery packs before making any adjustments or
removing/installing attachments or accessories.
An accidental start‑up can causeinjury.
• 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.
