Basic Saw Operations
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 21 & 21a).
• 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 4310 0nly)
1. Insert clamp post into clamp hole.
2. Loosen wing nut and ad-
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
clamp.
Quick-Action Clamp (Model 4410 only)
1. With clamp in open (lever
raised) position, insert
clamp into clamp post until
rubber foot comes into
contact with material.
2. Press down on lever to
tighten clamp.
3. Move the head assembly
to check clearance with
clamp.
4. Pull up on lever to release 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 MS1228 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.

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).
