Cleaning

WARNING: To reduce the risk of injury,
remove battery pack before cleaning.
CAUTION: When cleaning the pole saw
power head, do not immerse in water or
other liquids.
• Remove wood chips and other debris from the
battery port Make sure the contacts are clean
and dry
• After use, clean debris from the saw chain and
guide bar Wipe power head with a clean cloth
moistened with a mild soap solution Never
use harsh cleaners or solvents
• Always clean out wood chips, saw dust, and
dirt from the bar groove when replacing the
chain

Sharpening the Saw Chain

It is recommended that an Oregon® Service
Dealer sharpen the chain, but it can also be
sharpened by the operator
WARNING: If the chain is incorrectly
sharpened or the depth gauge is set too
low, there is an increased risk of injury.
Always sharpen the chain according to the
specifications described in this manual.
IMPORTANT: Sharpening according to
these instructions will address minor
damage to the saw chain from contact with
dirt or similar occurrences. To repair more
serious saw chain damage (such as after
contact with concrete), take the chain to
an authorized Oregon® service dealer, or
replace the chain.

Maintenance and Cleaning
Chain sharpening requires these tools (available
in a kit from Oregon®; see "Specifications and
Components"):
• File guide
• 4 5 mm round saw chain sharpening file (use
only special saw chain sharpening files)
• 0 025 inch (0 65 mm) depth gauge tool
• Flat file
After collecting the tools, wear gloves and eye
protection, and remove the battery Then, file
the chain to set the depth gauge:
• Loosen the side cover knob and remove side
cover
• Adjust the tensioning screw as far back
toward the rear of the cutting head as it will
go
• Remove the chain
• Place the chain in a vise to hold it steady
• Place the depth gauge tool on top of the chain
so that one depth gauge protrudes through
the slot in the tool
• If the depth gauge extends above the top of
the slot, file the depth gauge down level with
the top of the tool using a flat file (Fig 34)
Never file the depth gauge down enough to
exceed the depth gauge setting specified in
this manual
