The spring tension for automatic quill recoil has
been pre-set at the factory. It should not need
adjustment under most normal circumstances. If
it does need adjustment, the spring housing is
located on the left side of the headstock.
3. Loosen thumb knob shown in Figure 34
2–3 turns (DO NOT completely remove
thumb knob).
To adjust spring tension:
1. DISCONNECT MACHINE FROM POWER!
2. PUT ON SAFETY GLASSES!
If the return spring should
come loose from the spring
cap and rapidly unwind,
laceration or impact inju-
ries could occur. Always
wear heavy leather gloves
and safety glasses when
adjusting the return spring
tension.

step, or force of spring will cause cover to
spin out of your hands.

Calibrating Depth
Stop
The depth stop accuracy may be improved by
calibrating the depth stop. Make sure the spindle
is retracted all the way into the quill, then follow
the
steps below.
To calibrate depth stop:
1. Lower depth stop (see Figure 36) until indica-
tor plate reaches bottom of its travel.
2. Using a 3mm hex wrench, loosen cap screw
shown in
Figure 36, and position plate so its
upper edge aligns with zero, then re-tighten
cap screw.
