Workpiece Support

Long workpieces have a tendency to tip over unless clamped down and

properly supported from underneath.

Clamps

Quick-Action Clamp - This clamp easily secures a workpiece in either of two (2) clamp holes behind the fence (Figure 19).

—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.

—With clamp in open (lever raised) position, insert clamp into clamp post until rubber foot comes into contact with material.

—Press down on lever to tighten clamp.

—Move the head assembly to check clearance with clamp.

—Pull up on lever to release clamp.

!WARNING 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.

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 4412’s base extensions to extend out to 60”. Even after these longer rods are installed on the 4412, the base exten- sions 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 thick- nesses can be used to create auxiliary support exten- sions for long workpieces (Figure 21).
