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 21 & 21a).

to be effective.
• Adjust screw if necessary to clear fence or for large
differences in wood heights.

Sliding Base Extensions – These extensions pro-
vide extra workpiece support and are especially
useful when cutting long workpieces. To reposition
the extensions, simply unlock the Base Extension
Clamping Levers, reposition the extensions, and re-
lock the levers (Figure 22). (See also Length Stop
on page 30.)
Extra-long Base Extension Rods – The optional
MS1229 Base Extension Kit allow the 4310 or
4410's base extensions to extend out to 50-1/2".
Even after these longer rods are installed on the
base, the base extensions can be fully retracted for
transportation and storage.

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 1x. Boards of these
thicknesses can be used to create auxiliary support
extensions for long workpieces (Figure 23).
