SAW MAINTENANCE
Follow maintenance instructions in this
manual. Proper cleaning of saw and chain and
Guide Bar maintenance can reduce chances of
kickback. Inspect and maintain saw after each
use. This will increase the service life of your
saw.
Note: Even with proper sharpening, risk of
kickback can increase with each sharpening.
MAINTENANCE AND
STORAGE OF CHAIN SAW
If the replacement of the supply cord is
necessary, this has to be done by the
manufacturer or his agent in order to avoid a
safety hazard.
1. Unplug chain saw from power source
• Whennotinuse
• Beforemovingfromoneplacetoanother
• Beforeservicing
• Beforechangingaccessoriesor
attachments, such as saw chain and guard
2. Inspect chain saw before and after
each use. Check saw closely if guard or
other part has been damaged. Check for
any damage that may affect operator safety
or operation of saw. Check for alignment or
binding of moving parts. Check for broken
or damaged parts. Do not use chain saw if
damage affects safety or operation. Have
damage repaired by authorized service
center. To locate an authorized service
center, visit www.worxyardtools.com

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.
Turn the bar over, top rail becoming bottom
and bottom rail becoming top, around every 5
hours of use.
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 (See Fig. N).
3. Make sure to clean oil passages thoroughly
Conditions which require Guide Bar(9)
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, with unit disconnected from
power source, clean all sawdust from the
guide bar and sprocket hole.
When rail top is uneven, use a flat file to
restore square edges and sides.
File Rail Edges
and Sides
Square
Worn Groove Correct 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.
Always include new Drive Sprocket(15) when
replacing chain. This will maintain proper
driving of chain.
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 (22) catch into the
new bar by tightening the screw clockwise. The
catch protrude (a) must be fitted into the bar
hole. (See Fig O)
SHARPENING SAW CHAIN
WARNING: Unplug chain saw 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 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.P).
3. To rotate the sprocket release the chain
stop and pull the chain by hand until
the ungreased side of the sprocket is in
line with the grease hole. Repeat the
lubrication procedure.
