MAINTAINING THE SAW CHAIN
For safe, ecient operation, the saw chain must be maintained properly.
The saw chain will wear with use, causing the chain to stretch. This is normal. When it is no longer
possible to obtain a correct chain-tension adjustment, the saw chain will need to be repaired by an
authorized service center or replaced. Refer to Replacing the Guide Bar and Saw Chain.
Always keep the saw chain sharp. During operation, look for the following indicators of a dull saw chain:
• Wood chips are small and powdery.
• The saw chain must be forced through the wood.
• The saw chain cuts to one side.
If any of these conditions exist, sharpen or replace the saw chain. Refer to Replacing the Guide Bar and
Saw Chain.
NOTE: If you do not fully understand the process for properly sharpening a saw chain, have the saw
chain sharpened by an authorized service center or replace the saw chain.
REPLACING THE GUIDE BAR AND SAW CHAIN
When replacing the guide bar and saw chain, only use the replacement parts specied by the
manufacturer or their equivalents. Refer to Replacement Parts. Use of any unauthorized parts or
accessories could lead to serious injury to the operator or damage to the unit and will VOID the warranty.
Always use a replacement saw chain designated as “low-kickback” or a saw chain that meets the low-
kickback performance requirements. A standard saw chain (a chain that does not have the
kickback-reducing guard links) should only be used by an experienced professional pole saw operator.
CAUTION: The saw chain is very sharp. Always wear heavy-duty protective gloves
when handling or performing maintenance on the saw chain.
WARNING: An improperly sharpened saw chain increases the chance of kickback.
Failure to replace or properly maintain the saw chain can cause serious injury.
WARNING: Always use a low-kickback saw chain, which signicantly reduces the
danger of kickback. Low-kickback saw chain does not completely eliminate kickback. A
low-kickback or “safety chain,” should never be regarded as total protection against injury.
