Adjusting The Chain Tension - Remington RM4040 Manuel De L'utilisateur

ADDING BAR AND CHAIN OIL
DANGER:
Failure to fill the chain oil reservoir will cause
irreparable damage to the unit. Make sure the chain oil
reservoir is always filled. Always use bar and chain oil.
WARNING:
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.
Checking the Chain Oil Level
1. Set the unit on a flat, level surface. Position the unit upright
(Fig. 36).
2. Look into the chain oil level window. The oil level should fill the
window at least halfway (Fig. 36). 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 flat, level surface. Position the unit with the
chain oil cap facing up (Fig. 37).
2. To prevent debris from entering the chain oil reservoir, use a clean
cloth to clean the chain oil cap and surrounding area.
3. Unscrew the chain oil cap (Fig. 37).
4. Carefully pour the oil into the chain oil reservoir. DO NOT overfill.
5. Reinstall the chain oil cap. Tighten the chain oil cap firmly.
6. Wipe up any oil that may have spilled.

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. Always turn the unit off and remove the battery 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 and during operation. The saw chain
will expand as it heats up during operation. Adjust the chain tension
whenever the flats on the saw chain hang out of the bar groove (Fig.
38 and Fig. 42).
