MAiNTENANCE
Adding bar and Chain Oil
DANGER
Failure to fill the chain oil reservoir will cause irreparable
damage to the unit and void warranty. Make sure the chain oil
reservoir is always filled. Always use bar and chain oil.
wARNiNG
Oil constantly flows 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.
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
efficiency, shorten the life of the saw chain, cause rapid dulling
of the saw chain and excessive wear to the guide bar from
overheating.
An insufficient amount of lubricating oil is evidenced by smoke,
guide bar discoloration or pitch build-up. Only use bar and chain
oil that is formulated to perform over a wide range of temperatures
with no diluting required in the chain oil reservoir. Do not use
motor oil or any other petroleum-based oil. Do not use dirty, used
or contaminated oil. Damage may occur to the guide bar or saw
chain. Dispose of old oil according to federal, state and local
regulations.
1. Set the unit on a flat, level surface.
2. To prevent debris from entering the chain oil reservoir,
use a damp cloth to clean the chain oil reservoir cap and
surrounding area.
3. Unscrew the chain oil reservoir cap (Fig. 22).
4. Carefully pour the oil into the chain oil reservoir.
DO NOT overfill.
5. Reinstall the chain oil reservoir cap.
6. Wipe up any oil that may have spilled.

Adjusting the bar And Chain Oil flow
Bar and chain oil will slowly flow from the chain oil reservoir onto
the chain. Approximately one tank of bar and chain oil is used for
every tank of fuel.
–
To increase the oil flow, turn the automatic oiler adjustment
screw counter clockwise with a flat-head screwdriver (Fig. 23).
–
To decrease the oil flow, turn the automatic oiler adjustment
screw clockwise with a flat-head screwdriver (Fig. 23).

Adjusting the Chain Tension
CAUTiON
The guide bar, saw chain, and saw bearings will wear more
rapidly if the saw chain is not properly tensioned. Maintaining
proper chain tension will improve cutting performance and
prolong the life of the saw chain.
wARNiNG
To prevent serious injury, NEVER touch the saw chain or adjust
the chain tension while the unit is running. Disconnect the
spark plug wire to prevent the unit from starting accidentally.
wARNiNG
The saw chain is very sharp. Always wear heavy-duty
protective gloves when handling or performing maintenance on
the saw chain.
Check the chain tension before use and visually during operation.
Adjust the chain tension whenever the flats on the saw chain hang
out of the bar groove (Fig. 24).
1. Make sure the chain brake is disengaged. Refer to
Testing the
Chain Brake
in the
Assembly
section.
