5 IMPORTANT SAFETY INSTRUCTIONS
￭ Use of metal cutting attachments, wire or metal-reinforced
line or other non-approved cutting attachments is not
authorized and could be extremely dangerous.
– Never use metal blades or metal-
reinforced line on this trimmer. Use only
the cutting attachments recommended in
this manual, in combination with the
recommended deflector. See
Combinations of Deflectors and Cutting
Attachments, @ 25.1.
￭ To reduce the risk of severe personal injuries from
unintentional starting:
– Never touch the cutting attachment or
mowing head with your hand, feet or any
other part of your body while the battery
is inserted, even when the cutting
attachment is not moving. Keep
bystanders at least 50 ft. (15 m) away.
– Remove the battery before installing or adjusting the
bump guard.
– If the mowing head, cutting attachment
or deflector becomes dirty, clogged or
stuck, always switch off the motor, make
sure the cutting attachment has stopped
and remove the battery before inspecting
the cutting attachment and deflector.
Clean dirt, grass, weeds and other
material from the mowing head and
deflector at regular intervals, but only
after removing the battery.
￭ A damaged or loose cutting attachment or mowing head
may vibrate, crack, break or come off the trimmer, which
may result in serious or fatal injury.
– Make sure the cutting attachment and mowing head
are properly tightened before starting work.
– Check the tightness and condition of the cutting
attachment and mowing head before starting work
and any time trimming behavior changes during use.
Always switch off the motor, wait for the cutting
attachment to stop and remove the battery before
inspecting the trimmer or its cutting attachment.
