MAINTAINING THE BATTERY CHARGER
• Keep the battery charger clean and clear of debris. Do not allow
foreign material into the charging dock or onto the terminals (Fig.
15). Inspect the battery charger for foreign material before each use.
• Make sure the charger has not been shorted by debris. Inspect
the terminals for soot and signs of melting. Do not attempt to
use a shorted charger.
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. 16).
2. Look into the chain oil level window. The oil level should fill the
window at least halfway (Fig. 16). 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. 17).
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. 17).
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.
