13. Check with a paper strip to be certain the
blade has not moved back into contact with the
flange. Readjust, if necessary.
14. Using the blade tension knob, reapply tension
to the blade so it does not slip on the wheels.
15. Turn the saw OFF.
16. Close the blade guard cover and install and
tighten the thumb screw.
10.4 Replacing guide bearings
1. Remove the blade according to instructions 1
through 5 in Changing blades, sect. 9.12.
2. Remove the snap ring which holds the bearing
to the shaft.
3. Press off the bearing.
4. Press on the new bearing and secure it with
the snap ring.
5. Reinstall the blade according to instructions 6
through 10 in Changing blades.
6. Adjust the bearing spacing according to
instructions in Adjusting guide bearings.
10.5 Adjusting back-up bearings
Refer to Figure 19.
1. Disconnect the saw from its electrical power
source.
2. Loosen the guide bearing seat retaining bolt.
3. Slide the bearing seat as necessary until the
back-up bearing just touches the back edge of
the saw blade.
4. Tighten the guide bearing seat retaining bolt.
5. Restore electrical power to the saw.

10.6 Adjusting the arm stop
adjustment bolt
Refer to Figure 1.
1. Lower the arm to its fully lowered position.
The saw blade should be level and the cutting
edge of the blade should be in the relief slot,
below the level surface of the saw base. If this
is not the case, adjust the arm height as
follows:
2. Loosen the leveling bolt lock nut.
3. Adjust the leveling bolt until it supports the arm
and blade correctly as described above -- level
and below the top of the saw base.
4. Tighten the leveling bolt lock nut.
10.7 Adjusting motor switch actuator
This task should be performed whenever the arm
stop adjustment is corrected or whenever the saw
is turning off incorrectly.
Refer to Figure 1.
1. Raise the arm until the switch actuator is not in
contact with the switch.
2. Turn the switch ON.
3. Open the hydraulic control valve so the arm
moves slowly downward.
4. The motor switch should shut off just as the
arm contacts its horizontal stop bolt and the
blade is fully below the blade relief in the saw
base. If the motor shuts off too soon, or not at
all, adjust the switch actuator by bending it, as
required, to correct the fault condition.
11.8 Replacing a back up bearing
1. Remove the blade according to instructions 1
through 5 in sect. 9.12.
2. Remove the guide bearing assembly from the
saw arm by removing the guide lock knob and
sliding the assembly from the arm.
3. Use a drift to knock out the pin until until the
bearing can be removed.
4. Replace the bearing and press the shaft back
into the seat.
5. Reinstall the bearing assembly in the arm.
6. Reinstall the blade according to instructions 6
through 9 in sect. 9.12.
7. Adjust the back-up bearing spacing according
to instructions in Adjusting back up bearing
clearance.
11.9 Adjusting the bearing guide
seats for blade vertical
1. Install a new blade according to instructions in
