Cut-off Saws & Concrete Saws

Replace the belt when it becomes very worn
(peeling, turning, cuts, cracking, etc.)

Step 1.
Disconnect the water-flush pipe from the pipe connector.

Step 2.
Loosen the tension screw and then remove the 2 pulley cover bolts.
Step 3.
Remove the pulley cover along its rail.
Step 4.
Loosen the clutch cover bolt and then remove the clutch cover.

Step 5.
Remove the old belt and then remove the cutter arm.

Step 6.
Put the new belt on the small pulley.
Step 7.
While pulling the belt in the direction of the cutter, install the clutch cover and fasten it with its bolt.

Step 8.
Fit the cutter arm into the long hole in the
crankcase and then put the belt on the large pulley.
Step 9.
Put the pulley cover on along the outside of the cutter arm. Make sure the pulley cover is not misaligned when putting it into the arm.

Step 10.
Tighten the 2 pulley cover bolts and then back
them off 1 turn. Adjust the tightness of the belt.

Step 11.
Tighten the 2 pulley cover bolts. Note: Tighten to a torque of 23 to 27N･m (230 to 270 kgf･cm, 200 to + 234 lbf•in).
Step 12.
Insert the water-flush pipe into the pipe connector.
Step 13.
The belt stretches after being replaced, so readjust its tension after operating the machine.

Adjust the belt if it becomes loose.

1. Loosen the 2 pulley cover bolts about 1 turn.

2. Turn the tension screw so the washer lines up with the mark on the clutch cover.

3. Tighten the 2 pulley cover bolts. Note: Tighten to a torque of 23 to 27N･m (230 to 270 kgf･cm, 200 to 234 lbf•in).
