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.
