Adjusting
Cutterhead Guard
The cutterhead guard protects the user from
exposure to the cutter and chips thrown by
it. To minimize the risk of injury, the guard
must be adjusted so it encloses as much of the
spindle area as possible, while still allowing the
workpiece to pass through the cut. Typically, this
means the guard is positioned to just clear the
top of the workpiece.
To adjust cutterhead guard:
1. DISCONNECT MACHINE FROM POWER!
2. Loosen guard position lock knobs, adjust
guard forward or backward as needed, and
tighten knobs (see Figure 35).
3. Loosen guard height lock knobs, adjust front
guard up or down, and tighten knobs (see
Figure 35).

All guards MUST be installed on shaper before
operation. Shapers can quickly cause serious
injury if some kind of guard is not used. To
reduce risk of injury, read and follow entire
Owner's Manual carefully and do research on
shop-made guards and safety jigs.
Note:
To make your own box guard, see Making
Box Guards on Page 43 to find instructions and
tips.
