NOTE: One notch of the scale equals 1mm.

6.With your fingers on the shank portion of the cutter, carefully rotate the cutter toward the plus (+) or minus (-) position as needed.

7.When satisfied with the adjustment, tighten both set screws firmly.

8.Re-attach the spring on the headstock, and re-install the dust hood.

Drive Belt Tension

The tightness of the belt that drives the spindle has been adjusted at the factory. Further adjustment may be necessary after the machine receives some use, as the belt may stretch slightly during the “breaking in” process.

Belt tension can be adjusted by a socket head cap screw at the rear of the headstock (Figure

26)which slides the motor toward or away from the spindle. To tighten the belt, rotate this cap screw clockwise with a 6mm hex wrench. To loosen the belt, rotate the cap screw counterclockwise. The belt should be just tight enough to prevent it slipping on the spindle during operation.

Replacing cutter

The cutter is very sharp; use caution when working with or around cutter. Disconnect machine from power source! Failure to comply may cause serious injury.

1.To replace the cutter, loosen both set screws (Figure 25) and carefully pull up on the cutter until it is free from the spindle.

2.Slide the new cutter down into the spindle, and align the cutting edge with your previous setting on the spindle scale.

3.Tighten both set screws.

Oil Output

Oil is distributed through the air lines for constant lubrication of the clamping system. The oil output can be adjusted by rotating the oil regulator knob (A, Figure 27). Turn the knob counterclockwise to increase oil output, clockwise to decrease oil output.

The level of oil should be checked occasionally and re-filled as necessary. A minimum level is marked on the window of the oil cup (C, Figure 27). Refill by removing the screw (B, Figure 27) and pouring oil into the fill hole. When finished, re-install screw (B, Figure 27). Use standard air tool oil. This is available from your local distributor, or can be found in most hardware and tool stores.
