Installing the coolant kit
1. Install the baffle in the tank so the pump is held at one
end of the tank.
2. Put the tank and pump assembly in the flanges which
hold it in the saw base. The pump should be at the saw
motor end of the base.
3. Install the nozzle assembly in the fixture in the right-
hand guide bearing bracket and secure it with the set
screw in the fixture.
4. Install the delivery hose between the nipple on the
pump and the nipple on the nozzle assembly.
5. Install the return line between the nipple on the table
and the empty side of the tank.
6. Wire the pump motor to the pump switch according to
the wiring diagram on the facing page. Female spade
clips for the pump-to-switch connections are not supplied
with the kit and must be sourced locally, by you.
7. Test the system by putting coolant in the tank and
turning on the pump switch and motor switch.
8. The system is ready for use on the saw.
Chip brush replacement
The chip brush is a circular wire brush which is
mounted in a bracket at the right-hand side of the saw
arm. The purpose of the brush is to remove chips from
the saw teeth and off of the blade so excessive amounts
of chips don't get into the wheel guard section of the saw.
The brush shaft spins in the bracket and the shaft is
secured using a set screw and collar. With extended use
this brush will be worn and require replacement.
1. Disconnect the saw from its power source to prevent
accidental motor start-up.
2. Remove the set screw and collar from the brush shaft.
3. Remove the old brush and replace it with a new one.
4. Install the collar and set screw so the brush can spin
freely in the bracket.
5. Adjust the bracket, if necessary, so the brush makes
light contact with the saw blade.
Adjusting the horizontal stop
and motor switch
The horizontal stop and motor switch are located on
the front of the saw table at the left hand side. The
horizontal stop is a rubber disc, mounted on a flat-headed
screw. The screw height, and therefore the horizontal
position of the saw arm, is adjusted using two nuts on the
screw.
The motor switch is supposed to turn the motor off
just before the arm contacts the horizontal stop. In this
way a complete cut can be made and the blade can be
automatically stopped before the arm is lifted to set up
another cut.
Adjust the horizontal stop whenever the rubber disc
is worn to the point where the stop requires replacement.
To replace or adjust the hori-
zontal stop:
1. Disconnect the saw from its electrical power source to
prevent accidental motor start up.
2. Raise the saw arm to its full up position.
3. Remove the lower nut which secures the horizontal
stop screw to the saw and remove the horizontal stop
assembly, complete.
4. Install the new horizontal stop and make the nuts
which secure it finger tight.
5. Lower the saw arm to its horizontal position.
7. Adjust the horizontal stop height, using the upper and
lower nuts, until the saw blade is below the level of the
table surface and is fully into the blade relief slot on the
table.
8. To be certain the blade has made enough downward
travel to make a complete cut on the largest workpiece
which fits in the saw:
8.1. Open the adjustable vise jaw to its widest position
8.2. Place a straight edge flat on the saw table and
move it to where it contacts the blade.
8.3. The saw blade teeth should be below the saw table
along the entire distance you can slide the straight edge.
Adjust the horizontal stop until this condition is met.
9. Tighten the horizontal stop nuts securely.
10. Reestablish the electrical connection to the saw and
proceed to adjust the motor switch actuator.
Adjusting the
motor switch actuator
1. Raise the arm until the switch actuator is not in contact
with the switch.
2. Turn the switch ON.
3. Lower the arm until the arm contacts the horizontal
stop. The motor switch should shut off the motor just
before the arm contacts the horizontal stop.
4. If necessary, bend the switch actuator and re-test the
system until the correct motor shut-off instant is obtained.
