sIDE PLATE ANGLE
See Figure 36.
 CORRECT - 80° Produced automatically if
correct diameter 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 37 - 39.
 The Raker (depth gauge) should be main-
tained 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 clearance.
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.
GUIDE BAR MAINTENANcE
See Figure 40.
When the guide bar shows signs of wear, reverse
it on the saw to distribute the wear for maximum
bar life. The bar should be cleaned every day of
use and checked for wear and damage.
Feathering or burring of the bar rails is a nor-
mal process of bar wear. Such faults should be
smoothed with a file as soon as they occur.
A bar with any of the following faults should be
replaced.

MAINTENANcE

 Wear inside the bar rails which permits the
chain to lay over sideways.
 Bent guide bar.
 Cracked or broken rails.
 Spread rails.
In addition, guide bars with a sprocket at their tip
must be lubricated weekly with a grease syringe to
extend the guide bar life. Using a grease syringe,
lubricate weekly in the lubricating hole.
Turn the guide bar and check that the lubrication
holes and chain groove are free from impurities.
REVERsING THE GUIDE BAR
 Remove the chain from the bar and turn the
bar over.
NOTE: Bottom of bar should not be on top.
 Replace the chain on the bar. Refer to As-
sembling the Bar and chain earlier in this
manual for specific information.
 Tighten the screw with your finger.
 From the finger-tight position, tighten the
screw an additional 3/4 of a turn using a
wrench.
WARNING: Remove the battery pack and
make sure the chain has stopped before you
do any work or making any adjustments on the
saw. Failure to do so may result in accidental
starting and possible serious injury.
TRANsPORTING AND sTORING
See Figure 41.
 Do not store or transport the chain saw when
it is running. The chain saw should always be
idle before storing or transporting.
 Always place the chain cover on the bar and
chain before storing or transporting the chain
saw. Use caution to avoid the sharp teeth of
the chain.
 Clean the chain saw thoroughly before stor-
ing. Store the chain saw indoors, in a dry
place that is locked and/or inaccessible to
children.
 Keep away from corrosive agents such as
garden chemicals and de-icing salts.
