Unplug unit 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.
WARNING:
SHARPENING THE SAW 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 a few large
chips, then chain is dull.
Purchase a new chain, have your chain sharpened
professionally at a qualied service center, or sharpen
the chain yourself using a proper sharpening kit. The
height difference between the cutting tip and the ridge is
the depth gauge setting.
When you sharpen the cutting tip, the depth gauge
setting between the tip and the side plate ridge will
decrease. To maintain optimal cutting performance, the
ridge has to be led down to achieve the recommended
depth gauge setting.
To sharpen the chain:
1. Using protective gloves, ensure the chain is correctly
tensioned on the guide bar.
2. Use a round le with a diameter 1.1 times the cutting
tooth depth. Make sure 20% of the le diameter is
above the cutter’s top plate.
NOTE: A le guide is available from most pole saw
retailers and is the easiest way to hold the le at the
correct position.
3. File at an angle perpendicular to the bar, and at an
angle of 25˚ to the direction of travel.
4. File each tooth from the inside towards outside only.
File one side of the chain rst then turn the saw around
and repeat the process.
• Sharpen each tooth equally by using the same
number of strokes.
• Keep all cutter lengths equal. Each time the cutting tip
is sharpened the cutting length is reduced. When the
cutter length is reduced to 0.16 inch (4 mm), the chain
is worn out and should be replaced.
• The depth gauge setting is also reduced with each
sharpening.. Every 5 sharpenings use a depth gauge
measuring tool to check the height between the
cutting tip and the ridge. When necessary, use a at
le to le down the ridge to achieve the .025 inch
depth gauge setting. Depth gauge measuring tools
are available from most pole saws retailers.
• If the saw is not functioning properly, take it to a
qualied pole saw service center to have the saw
inspected. Use only identical parts as listed in this
manual.
