STARTER ROPE
If your starter rope breaks near the pulley, it can be repaired
by the following method, otherwise replace the rope:
1. Remove the fan housing.
2. Remove screw using a 3/16 alien wrench. Figure 22.
3. Lift out pulley.
4. Tie a knot in one end of the rope. Heat and flatten the knot
end to prevent knot from slipping. Heat opposite end of
rope and form a point. Feed pointed end of rope through
the pulley and under the pulley bridge. Pull the rope
through until the knot is tight against the pulley. Figure 22.
5. Pass the pointed end of the rope through the hole in the fan
housing and then the starter handle. Tie a double knot and
insert knot end of rope back into the handle. Pull the slack
out of the rope and wrap the rope on the pulley in a
clockwise
direction.
6. Apply light grade silicone lubricant to the pulley bore and
place pulley back in the fan housing. Place the pulley
washer in position and secure with the pulley screw.
7. To retension the starter spring pull a loop of rope from the
pulley approximately 12 in. long. Secure the rope in the
notch in the pulley and using the rope turn the pulley
THREE TURNS counterclockwise
• Release the
rope from the notch and allow to rewind slowly on pulley.
Figure 23.
8. Replace the fan housing.
GUIDE BAR MAINTENANCE
Check the condition of the guide bar often. A worn bar will
damage the chain and make cutting harder.
1. Figure 24 shows a cross-section of the guide bar. Keep the
edges square as in (1) with a flat file.
2. Rollover is shown in (2). This will cause you to press extra
hard when cutting.
3. Worn rails are shown in {3}. This occurs most often at the
guide bar nos^.
4. Uneven rails are shown in (4). This will cause the saw to cut
on an angle.
5. Keep the rails flat and square as shown in (1).
6. Grease S/N Bar before use and at least 3 times per day for
heavy use.
CHAIN SHARPENING
Keep Your Chain Sharp
Dirt will dull a chain instantly. Keep the chain out of the dirt.
If the chain cuts to one side, it is dull.
Extra rough cutting is a sign of a dull chain.
Powder-like wood chips mean a dull chain.
Cutting is much easier and safer with a sharp chain.
To Sharpen
1. Set the chain tension tight. You must still be able to move
the chain around the bar.
2. Clamp the guide bar in a vise. Don't clamp the chain!
Clamp in the center of the bar.
3. Use only a 7/32" round file.
4. Sharpen all the cutters away from you first. Then turn the
saw around and sharpen the cutters on the other side.
5. Position file holder at 10° angle (Figure 25) and align the
30 file holder marks with the bar as shown in Figure 26,
6. File in ONE direction only! Figure 27.
7. Press hard! Two or three strokes should do it.
8. Always check the depth gauge with the depth gauge filing
guide after filing. If the depth gauge sticks out, file it off
with a flat file. Figure 28.
