9.0 Operating Instructions

9.1 Clamping material s in the vise

Refer to Figure 1.

1. Li ft th e saw arm to it s full up positi on.

2. Lock the arm up using the hydraulic feed control valve.

NOTE: Use the handle on the arm to lift the arm. Never use any other part of the arm as a lifting method.

3. Open the left vise by turning the vise handwheel counterclock wise.

4. Adjust the vise jaws for the appropriate cutting angle, if required. See sections on Right angle cutting and Angle cutting.

5. Put the work piece material between the vise jaws.

NOTE: If the work piece material is long, support both the ends of the material as needed to keep the material level on the saw base.

6. Turn the vise handwheel clockwise until the work piece is secu rely cla m ped in the vi se.

7. Proceed to cut according to instructions in Cutt ing procedur e.

9.2 Right angle cutting

Refer to Figures 1 and 8.

If you want to be certain the workpiece is being held in the vise at exactly 90 degrees to the blade for cutoff work, use the following procedure to check the bla de-to- jaw angle.

1. Disconnect the saw from its electric power source.

2. W ith the saw arm in its fully lowere d positio n, place a machinist's square,or a machinist's protractor 90 degrees, against the saw blade and rig ht vis e jaw. If the jaw is squa re to the blade, then no adjustment is required.

3. If adjustment is required, see Angle Cutting. The procedure for setting the jaw angle with respect to the blade is described in that section.

Figur e 8: Using a pr otractor to set the vise jaws at desir ed angle. By setting the pr otractor to 90 degrees, or using a machinist's sq uare, t he jaws can also be set square with res pect to t he blade.

4. Lift the saw arm to its full up position and lock it up using the hy draulic feed control kn ob.

NOTE: Use the handle on the arm to lift the arm. Never use any other part of the arm as a lifting method.
