English 5 IMPORTANT SAFETY INSTRUCTIONS
– Never work with a damaged or malfunctioning power
tool or battery. In case of doubt, have the power tool
and battery checked by your authorized STIHL
servicing dealer.
￭ If the power tool or battery is damaged, not working
properly, has been left outdoors or dropped into water or
other liquid, its components may no longer function
properly and safety devices may be inoperative. To
reduce the risk of personal injury and property damage:
– Take the power tool and battery to your authorized
STIHL servicing dealer to be checked before further
operation.
￭ Genuine STIHL replacement parts are specifically
designed to match your power tool and meet safety and
performance requirements. Use of parts that are not
authorized or approved by STIHL may cause serious or
fatal injury or property damage.
– STIHL recommends that only identical STIHL
replacement parts be used.
5.7 Using the Trimmer / Brushcutter
5.7.1 Before Operation
WARNING
￭ Misuse or unauthorized use may result in personal injury
and property damage.
– Use the trimmer / brushcutter only as described in
this instruction manual.
￭ The cutting attachment and deflector must be an
approved combination.
– Read and follow the instructions on selecting the
proper cutting attachment and deflector, @ 25.
￭ The cutting attachment must be properly installed and
tightened before starting work. Failure to use the proper
parts to mount the cutting attachment may cause the
blade or mowing head to fly off and seriously injure the
operator or bystanders.
– Read and follow the instructions on mounting the
cutting attachment, deflector and handle, @ 11.
– Never mount a cutting attachment to the trimmer /
brushcutter without the proper installation of all
required parts (e.g., nuts, screws, thrust washer,
thrust plate, etc.).
– Before starting work, inspect for loose parts (nuts,
screws, etc.) and for a cracked or damaged head or
a cracked, bent, warped or damaged blade.
– Replace damaged heads or blades before using the
power tool.
– Always keep metal cutting attachments sharp.
￭ Using only an approved combination of cutting attachment
and deflector is extremely important to maximize cutting
performance and reduce the risk of personal injury from
thrown objects or contact with the cutting attachment:
– To reduce the risk of serious injury, never use wire
or metal-reinforced line or other material in place of
the recommended nylon cutting line. Pieces of wire
could break off and be thrown at high speed toward
the operator or bystanders.
￭ Using a trimmer / brushcutter that is modified, damaged,
improperly adjusted or maintained, or not completely and
securely assembled can lead to a malfunction and
increase the risk of serious personal injury or death.
– Never operate a trimmer / brushcutter that is
modified, damaged, improperly maintained or not
completely and securely assembled.
– Always check your unit for proper condition and
operation before starting work, particularly the
retaining latch, trigger switch lockout, trigger switch,
deflector, harness and cutting attachment.
– Do not use circular saw blades on this
trimmer / brushcutter.
