Workpiece Support
Long workpieces have a tendency
_to tip over unless clamped down
and properly supported from underneath.
Clamps - The clamp easily secures a workpiece in
either of two (2) clamp holes behind the fence
(Figure 19 & 19a).
• Minimum of 1/2" of knurl must engage clamp post
to be effective.
• Adjust screw if necessary to clear fence or for large
differences in wood heights.
Workpiece Clamp (Model 5312 0nly)
1. Insert clamp post into clamp hole.
2. Loosen wing nut and ad- Wing
just arm to proper height,
and securely tighten wing
nut.
3. Rotate screw knob of
the clamp clockwise to
tighten, counter-clockwise
to loosen.
4. Move the head assembly
to check clearance with Ar
clamp.

_ There may be extreme compound
cuts where clamp cannot be used.
Support workpiece with hand outside No Hands
Zone. Do not try to cut short pieces that cannot
be clamped and cause your hand to be in the No
Hands Zone.
Horizontal Clamp - The optional MS1221 Horizon-
tal Clamp and crown stop can be mounted on either
side of the tool and holds the workpiece firmly
against the fence.
Conventional Clamps - and other hold down de-
vices can be used to hold the workpiece firmly
against the table and the fence.
Long workpiece support
Sliding Base Extensions - These extensions pro-
vide extra workpiece support and are especially use-
ful when cutting long workpieces. To reposition the
extensions, simply unlock the Base Extension
Clamping Levers, reposition the extensions, and re-
lock the levers (Figure 20). (See also Length Stop
on page 27.)
Extra-Long Base Extension Rods - The optional
MS1222 Base Extension Kit allow the 5312 or
5412's base extensions to extend out to 60". Even
after these longer rods are installed on the base, the
base extensions can be fully retracted for trans-
portation and storage.
Figure 20. Sliding Base Extensions
Blocks - Long pieces need extra support. The base
height (3-3/4") is designed to match the standard
lumber of two 2x's and one lx. Boards of these
thicknesses can be used to create auxiliary support
extensions for long workpieces (Figure 21).
