OILING THE CHAIN
The pole saw chain is self-lubricating. Oil is dispersed
onto the chain as the unit is used. Keep an adequate
amount of oil in the oil tank. Use the bar-chain oil
provided in the hardware pack. Always use bar-chain
and sprocket oil or similar chain saw oil.
GUIDE BAR MAINTENANCE
NOTE: Proper maintenance of the guide bar is essential
to the performance of your pole saw. Proper
guide bar maintenance will keep your saw in
good working order.
Most guide bar problems can be prevented merely by
keeping the chain saw well maintained.
Incorrect filing and non-uniform cutter and depth gauge
settings cause most guide bar problems, primarily
resulting in uneven bar wear. As the bar wears unevenly,
the rails widen, which may cause chain clatter and
difficulty in making straight cuts.
Insufficient guide bar lubrication and operating the saw
with a chain that is
too tight will contribute to rapid bar
wear. Refer to Saw Chain Tension Adjustment.
To help minimize bar wear, the following guide bar
maintenance is recommended:
Bar Wear
Turn guide bar frequently at regular intervals (for
example, after 5 hours of use), to ensure even wear on
top and bottom of bar.
Ensur
e that the unit
is off and the spark
plug is disconnected (gas powerheads) before
performing any maintenance on your saw.
WARNING:
Bar Grooves
Bar grooves (or rails which support and carry the chain)
should be cleaned if the saw has been heavily used or if
the saw chain appears dirty. Rails should always be
cleaned every time the saw chain is removed.
T
o clean guide bar rails:
1. Remove sprocket cover, bar and chain. Refer to Saw
Chain Replacement / Installation
.
2. Using a screwdriver, putty knife, wire brush or other
similar instrument, clear residue from the rails on the
guide bar (Fig. 14).
This will keep the oil passages open to provide
proper lubrication to the bar and chain.
3. Reinstall the bar, chain and bar bolt retaining nuts.
Refer to
Saw Chain Replacement / Installation.

Oil Passages
Oil passages at bar pad should be cleaned to insure
proper lubrication of the bar and chain during operation.
This can be done using a soft wire small enough to insert
into the oil discharge hole.
