MAINTENANCE AND REPAIR INSTRUCTIONS

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

Ensure that the unit WARNING: is off and the spark

plug is disconnected (gas powerheads) before performing any maintenance on your saw.

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.

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.

To 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.

Fig. 14

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.
