ADDING BAR AND CHAIN OIL
The guide bar and saw chain require lubrication to minimize friction. Never starve the guide bar and
chain of lubricating oil. Running the unit without enough oil will decrease cutting eciency, shorten
the life of the saw chain, cause rapid dulling of the saw chain and excessive wear to the guide bar from
overheating. An insucient amount of lubricating oil is evidenced by smoke, guide bar discoloration or
pitch build-up.
NOTE: Always use a high-quality, biodegradable bar and chain oil for proper saw chain and bar
lubrication. When pruning trees, vegetable-based bar and chain oil is recommended, as
mineral-based oils may harm living trees. Never use dirty, used, or contaminated oil. Doing so
may damage the tool. Dispose of old oil according to federal, state and local regulations.
Checking the Chain Oil Level
1. Set the unit on a at, level surface. Position the unit with the chain oil cap facing up (Fig. 14).
2. Make sure that the chain oil reservoir is at least half full (Fig. 14). If the oil level is too low, add bar
and chain oil. Refer to Filling the Chain Oil Reservoir.
Filling the Chain Oil Reservoir
1. Set the unit on a at, level surface. Position the unit with the chain oil cap facing up (Fig. 14).
2. To prevent debris from entering the chain oil reservoir, use a damp cloth to clean the chain oil cap
and surrounding area.
3. Unscrew the chain oil cap (Fig. 14).
4. Carefully pour the oil into the chain oil reservoir. DO NOT overll.
NOTE: The chain oil reservoir may be lled to the lip of the ll opening without damaging the unit.
5. Reinstall the chain oil cap. Tighten the chain oil cap rmly.
6. Wipe up any oil that may have spilled.
WARNING: Failure to ll the chain oil reservoir will cause irreparable damage to the
unit. Make sure the chain oil reservoir is always lled. Always use bar and chain oil.
WARNING: Oil constantly ows from the chain oil reservoir to oil the saw chain.
Check the chain oil level frequently so that it does not drop below half full.
