WARNING:
Failure to replace or repair damaged chain can cause
serious injury.
NOTICE:
A dull or improperly sharpened chain can cause excessive
engine speed during cutting, which may result in severe
engine damage.
TOP PLATE FILING ANGLE
See Figure 25.
„ CORRECT 30° - File holders are marked with guide marks
to align file properly to produce correct top plate angle.
„ LESS THAN 30° - For Cross Cutting.
„ MORE THAN 30° - Feathered Edge Dulls Quickly.
SIDE PLATE ANGLE
See Figure 26.
„ CORRECT - 80° Produced automatically if correct diam-
eter file is used in file holder.
„ HOOK - "Grabs" and dulls quickly. Increases potential of
KICKBACK.
„ Results from using a file with diameter too small, or file
held too low.
„ BACKWARD SLOPE - Needs too much feed pressure,
causes excessive wear to bar and chain.
„ Results from using a file with diameter too large, or file held
too high.
DEPTH GAUGE CLEARANCE
See Figure 27 - 28.
„ The depth gauge should be maintained at a clearance of
.025 in. Use a depth gauge tool for checking the depth
gauge clearances.
„ Every time the chain is filed, check the depth gauge clear-
ance.
Use a flat file and a depth gauge jointer to lower all gauges
uniformly. Depth gauge jointers are available in .020 in. to .035
in. Use a .025 in. depth gauge jointer. After lowering each depth
gauge, restore original shape by rounding the front. Be careful
not to damage adjoining drive links with the edge of the file.
Depth gauges must be adjusted with the flat file in the same
direction the adjoining cutter was filed with the round file. Use
care not to contact cutter face with flat file when adjusting
depth gauges.
MAINTENANCE
MAINTAINING THE GUIDE BAR
See Figure 29.
CAUTION:
Make sure the chain has stopped and the battery pack
has been removed before you do any work on the saw to
avoid accidental starting or contact with the moving chain
that may result in injury.
Proper maintenance will maximize the useful life of the guide
bar.
Each day of use:
Clean the bar and check for wear and damage. Feathering or
burring of the bar rails is a normal process of bar wear, but such
faults should be smoothed with a file as soon as they occur.
Each week of use:
„ Reverse the guide bar on the saw to distribute the wear.
„ Lubricate the socket at the end of the guide bar using a
grease syringe in the lubricating hole.
„ Turn the guide bar and check that the lubrication holes and
chain groove are free from impurities.
A bar with any of the following faults should be replaced
immediately:
„ Wear inside the bar rails that permits the chain to lay over
sideways
„ Bent guide bar
„ Cracked or broken rails
„ Spread rails
TRANSPORTING AND STORING
See Figure 30.
WARNING:
Always remove the battery pack before transporting or stor-
ing pruning saw. Place battery pack indoors in a dry, secure
location out of the reach of children when storing. Failure
to follow these instructions may lead to accidental starting
or unauthorized use and result in serious personal injury.
„ Do not store or transport the pruning saw when it is run-
ning. The pruning saw should always be idle before storing
or transporting.
„ Always place the guide bar scabbard on the bar and chain
before storing or transporting the pruning saw. Use caution
to avoid the sharp teeth of the chain.
„ Store pruning saw on its side.
„ Clean the pruning saw thoroughly before storing. Store the
pruning saw indoors, in a dry place that is locked and/or
inaccessible to children.
„ Keep away from corrosive agents such as garden chemi-
cals and de-icing salts.
