your thumb and index finger. Roll the outer surface
against the palm of your other hand. Replace the
bearing if it does not rotate smoothly.
2. Needle Bearings (24): Insert shaft into bearings.
Spin shaft. If the shaft does not spin smoothly,
replace the entire assembly with bearings already
pressed in.
3. Saw Head Motor Body (1) and Motor Cap (22):
Inspect mating surfaces, bores, oil passageways,
etc. for grooves or nicks. If any component shows
wear or damage, replace the entire assembly with
bearings already pressed in.
4. Rim Sprocket (47) and Adapter (45): Inspect all
surfaces, including gear teeth, for grooves or chips.
A minor amount of wear, if it’s consistent among all
of the teeth (an even wear pattern), is acceptable.
The rim sprocket and adapter function as a unit. If
one of them needs to be replaced, replace both of
them. Also, replace the saw chain at the same time.
5. Guide Bar (55): Clean the oil passage at the base
of the guide bar. Use any instrument small enough
to thoroughly clean the passage.
Check the bar rails for wear by placing a straight
edge against the side of the bar and one cutter.
•Clearance between the bar and the straight edge
indicates that the bar rails are not worn.
•If the chain leans and there is little or no clear-
ance between the bar and the straight edge, the
bar rails are worn and the bar should be replaced.

Adjustments
Checking and Setting the Automatic Chain Oiler
The automatic chain oiler provides a constant supply of
oil to lubricate the bar and chain whenever the saw is
operating. An adjustment screw controls the amount of
oil supplied.
1. Run the saw at full rpm.
2. If the tip of the saw gives off a fine spray of oil, the
automatic oiler is working properly. If the saw does
not give off a spray of oil, adjust the oiler.
Note: For better results, hold saw so that the tip of
the saw blade is pointing toward a clean sheet of
paper or cardboard and run the saw at full rpm. If
the automatic oiler is working properly, the paper or
cardboard should soon show small droplets of oil.
3. Stop the hydraulic power source.
4. Twist the adjustment screw 1/2 turn as follows:
•clockwise to decrease the oiler output.
•counterclockwise to increase the oiler output.

5. Start the hydraulic power source.
6. Repeat until the oiler output is adjusted correctly.
New Chain Break-In
1. Run the saw at low chain speed without cutting
wood for 2 to 3 minutes. Check the output from the
automatic oiler.
2. Stop the hydraulic power source. Disconnect the
hoses. Allow the bar and chain to cool. Check the
tension and adjust if necessary.
3. Connect the hoses. Start the power source. Make a
few easy cuts at moderate chain speed.
4. Stop the hydraulic power source. Disconnect the
hoses. Allow the bar and chain to cool. Check the
tension and adjust if necessary.
5. Connect the hoses. Start the power source. Use the
saw for moderate cuts during the next 30 minutes of
use.
Checking Chain Tension
1. Stop the hydraulic power source. Disconnect the
hoses. Allow the bar and chain to cool.
2. Pull the saw chain around the bar. The chain should
rotate around the bar easily. If it does not, see
Chain is Difficult to Rotate Manually in the Trouble-
shooting table.
3. Check the tension as follows:
Pull the saw chain away from the bar (see the
illustration) using approximately 4.4 Newtons (2 lbs)
of force. The clearance between the chain and bar
should be approximately 3.2 mm (1/8"). If there is
too much or too little clearance, proceed to Adjust-
ing Chain Tension.

of force. The clearance between the chain and bar
should be approximately 3.2 mm (1/8").
3. Hold the bar nose up and tighten the two bar flange
nuts. Torque to 16.9 Newton-meters (150 inch-
pounds).
4. Check the chain tension again.
5. Rotate the chain around the bar manually. If you
hear a clicking noise, the chain drive links are hitting
the bar. Repeat the Adjusting Chain Tension
procedure.

Chain Saws with Chain Brake
Sharpening the Saw Chain
The saw chain must be sharpened to the
manufacturer’s specifications. If the saw chain is not
properly sharpened, the risk of kickback increases.
If using a filing guide or hand-held grinder, refer to the
manufacturer’s instructions provided with the unit.
Saw Chain Gauge
See Figure B. Gauge refers to the thickness of that
portion of the drive link which fits into the guide bar
groove. The guide bar and saw chain gauge must
match. Industry standards are .050, .058 and .063.
Saw Chain Pitch
See Figure A. Pitch refers to the saw chain measure-
ment. A chain’s pitch is the distance between any three
consecutive rivets divided by two. Example: .65 divided
by two equals .325 pitch.

Chain Saws with Chain Brake
Filing Depth Gauges
1. If the cutters are sharpened with a file holder, check
and lower the depth gauges before sharpening the
cutters.
2. Check the depth gauges every third sharpening.
3. Place the depth gauge tool on the cutter. If the
depth gauge projects, file it level with the top of the
tool. Always file from the inside of the saw chain
toward an outside cutter.
Lowering Depth Gauges
4. Round off the front corner to maintain the original
shape of the depth gauge after using the depth
gauge tool. Always follow the recommended depth
gauge setting of the chain manufacturer. This is
important for maximum performance throughout the
saw chain’s life as well as for protection against
kickback.
Rounding Off Depth Gauges
Filing Cutters —General
1. Support the file holder on the cutter top plate and
depth gauge as shown.

3. Keep the line on the file holder parallel to the center
of the saw chain. Reverse the procedure for the
other side.
