Servicing Hydraulic Oil
WARNING: SHUT OFF ALL ELECTRICAL
POWER TO THE MACHINE
1. Remove hydraulic oil reservoir access panel.
2. Check oil level (refer to Figure 16). If level is
below the yellow (upper) line, the reservoir should
be filled.
3. Disconnect electrical power.
4. Remove reservoir fill cap.
5. Add oil until the level is at the yellow (upper) line.
Install reservoir fill cap.
6. If a significant amount of oil needed to be added,
check for oil leaks in pump components, lines,
and hydraulic cylinder. Correct source of
leakage before operating the cut off saw.
7. Connect electrical power. Raise and lower the
saw head to confirm that the saw is operating
correctly.

3. Turn the blade tensioning hand wheel clockwise to
relieve tension on the blade. Loosen the blade
enough to remove the blade from the idler and
drive wheels. Remove the blade from between the
blade guides.
4. Install the new blade between the blade guide
bearings and the carbide blade guides. Install the
blade over the drive and idler wheels.
5. Turn the blade tensioning hand wheel counter-
clockwise to tighten the blade. Tighten the blade
until the blade tension indicator reads TBD.
6. Operate the saw at low speed and observe the
tracking of the blade. If tracking needs to be
adjusted, refer to Blade Tracking Adjustment.
7. Adjust the bearings on the upper edge of the
blade until they just contact the blade (see figure
19).
8. Check the guide bearings and the carbide guides
to make sure they are just contacting the sides of
the blade.
9. Install the left blade guard making sure there is
ample clearance with the blade.
10. Make a test cut to make sure the blade tracks
properly during operation. Adjust tracking as
required (see Blade Tracking Adjustment).
Changing the Drive Belt
1. Disconnect the electrical power source from the
cut-off saw to prevent any possibility of accidental
motor start-up.
2. Set the arm at the full horizontal position.
3. Remove the knob on the drive belt cover. Remove
the drive belt cover to expose the V-belt and
pulleys.
4. Remove two screws, nuts, and washers from back
of saw head support. Push on the motor support
bracket to pivot the motor upward to loosen the
tension on the belt.
5. Remove the worn belt.
6. Put the replacement belt in the pulleys. Allow the
motor to pivot downward.
7. Install the two screws, nuts, and washers in back
of saw head support and through the motor
support bracket.
8. Install the drive belt cover. Install and tighten the
knob on the drive belt cover.
Replacing the Drive Motor
1. Disconnect the motor from all electrical power.
Unplug the motor if it is plugged into a socket.
Shut off the power to the branch and remove the
connection to the junction box if the motor is hard
wired to the branch.
