cut from above(Y) about 1/3 of the diameter into the
log (overbuck) and then finish the cut (Z) from below,
in order to avoid contact of the pruning saw with the
ground. When sawing logs supported on only one end,
start the cut from below (Y) about 1/3 of the diameter into
the log (underbuck) and finish the cut from above (Z)
in order to avoid log splitting or jamming of the pruning
saw.
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 Pruning saw
1. Remove the battery pack
• 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 pruning 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 pruning saw if
damage affects safety or operation. Have damage
repaired by authorized service center. To locate an
authorized service center, visit www.worx.com.
3. Maintain pruning saw with care.
• Never expose saw to rain or direct moisture.
• Keep chain sharp, clean, and lubricated for better
and safer performance.
• Follow steps outlined in this manual to sharpen
chain.
• Keep handles dry, clean, and free of oil and grease.
• Keep all screws and nuts tight.
4. When servicing, use only identical replacement
parts.
5. When not in use, always store pruning saw
• in a high or locked place, out of children’s reach
• in a dry place
• with Bar and Housing-Cover in place
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 Housing-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.
Q)
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.
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 pruning 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.
SHARPENING SAW CHAIN
WARNING:
Remove the battery pack 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.
