English

discharge opening. Release bail handle to turn mower off,
remove the safety key
the grass collection bag
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
• If mower should start to vibrate abnormally, release bail
handle to turn mower off, remove the safety key and
battery pack. 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 pack 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 your battery pack be recharged
after each use to prolong the battery pack life. Frequent
charging will not harm your battery pack, and will ensure that
the battery pack is fully charged and ready for its next use.
nOTE: Storing the battery pack not fully charged will
shorten its life.
