Bar Maintenance
To maximize bar life, the following bar maintenance
is recommended.
The bar rails that carry the chain should be cleaned
before storing the tool or if the bar or chain appear
to be dirty.
The rails should be cleaned every time the chain is
removed.
To clean the Bar rails:
1. Remove chain cover and bar and chain. (see
section ASSEMBLY)
2. Using a wire brush, screwdriver or similar tool,
clear the residue from the inner groove of the bar.
3. Make sure to clean oil passages thoroughly
Conditions which require chain and guide bar
maintenance:
•
Saw cuts to one side or at an angle.
•
Saw has to be forced through the cut.
•
Inadequate supply of oil to the bar and chain.
Check the condition of the guide bar each time the
chain is sharpened. A worn guide bar will damage the
chain and make cutting difficult.
After each use, remove the battery pack, clean all
sawdust from the guide bar and sprocket hole.
20V 12" Brushless Chainsaw
When rail top is uneven, use a flat file to restore
square edges and sides.
File Rail Edges
and Sides
Square
Worn Groove
Replace the guide bar when the groove is worn, the
guide bar is bent or cracked, or when excess heating
or burring of the rails occurs. If replacement is
necessary, use only the guide bar specified for your
saw in the repair parts list or on the decal located on
the chain saw.
Replacing Bar & Chain
Replace chain when cutters are too worn to sharpen
or when chain stops. Only use replacement chain
noted in this manual.
Inspect guide bar before sharpening chain. A worn
or damaged guide bar is unsafe. A worn or damaged
guide bar will damage chain. It will also make cutting
harder.
Fit the bar tensioning plate tab into the new bar by
tightening the screw clockwise. The tab protrusion
(a) must be fitted into the bar hole. (See Fig. R)
SHARPENING SAW CHAIN
WARNING: Unplug chainsaw from power
source before servicing. Severe injury or death
could occur from electrical shock or body contact
with moving chain.
Cutting edges on chain are sharp. Use protective
gloves when handling chain.
Keep chain sharp. Your saw will cut faster and more
safely. A dull chain will cause undue sprocket, guide
bar, chain, and motor wear. If you must force chain
into wood and cutting creates only sawdust with few
large chips, chain is dull.
LUBRICATE SPROCKET
WARNING: Wear heavy duty gloves when
performing any maintenance or service to this
tool. Always unplug the tool before performing any
service or maintenance on this tool.
NOTE: It is not necessary to remove the chain or bar
when lubricating the guide bar sprocket.
1. Clean the bar and sprocket
2. Using a grease gun, insert the tip of the gun into
the lubrication hole and inject grease until it
appears at the outside edge of the sprocket tip
(See Fig. S).
3. To rotate the sprocket pull the chain by hand
until the ungreased side of the sprocket is in
line with the grease hole. Repeat the lubrication
procedure.
