WARNING
Remove the battery before adjustment, maintenance or
cleaning. Failure to do so could result in serious personal
injury.
You may only make adjustments or repairs described
in this manual. For other repairs, contact the authorized
service agent.
Consequences of improper maintenance may cause
the chain brake and other safety features to not function
correctly, thus increasing the potential for serious
injury. Keep your chainsaw professionally maintained
and safe.
Sharpening the chain safely is a skilled task. Therefore
the manufacturer strongly recommends that a worn or
dull chain is replaced with a new one, available from
your authorised Ryobi service centre. The part number
is available in the product specification table in this
manual.
Follow instructions for lubricating and chain tension
checking and adjustment.
After each use, clean the product with a soft dry cloth.
Check all nuts, bolts and screws at frequent intervals
for security to ensure the product is in safe working
condition. Any part that is damaged should be properly
repaired or replaced by an authorized service centre.
