Removing Tools from Spindle Bore
1. Disconnect the machine from the power
source.
2. Place a protective piece of scrap wood on the
table.
3. Raise the table to approximately 8” to 10”
below the spindle.
4. Lower the spindle to expose the slots in the
spindle wall.
5. Insert the drift key (A, Fig. 11) into the spindle
slots and tap gently until the drill bit or chuck
arbor loosens.
Coolant Pump
The coolant tank should be filled with 2 gallons of a
cutting coolant. Fill by pouring coolant into the
base of the machine. Add coolant in the same
manner when coolant is low. To drain coolant,
remove hex cap screw located on the lower
backside of the base. Follow all coolant
manufacturer’s instructions for safety, mixing
disposal, etc.
Make sure the drain hose has a good tight
connection into the table and that the coolant flows
into the base.
Make sure the hose leaving the pump and entering
the ball valve has good tight connections.
The flexible nozzle enables the user to adjust the
coolant for each job. There is one ball valve that
turns the coolant to the nozzle on, or off.

Adjusting the Spindle Return Spring
The spindle return comes pre-set from the factory
and should not need adjustment. If future attention
is ever required, proceed as follows:
1. Do NOT remove the spring cap (B, Fig. 12).
2. Loosen knob (A, Fig. 12) just enough to rotate
the spring cap past the notch (C, Fig. 12).
3. Rotate the spring cap clockwise to decrease
spring tension. Rotate the spring cap counter-
clockwise to increase spring tension.
4. Re-tighten the knob (A, Fig. 12).
