9.0 Operating Instructions

9.1 Clamping materials in the vise

Refer to Figure 1.
1. Lift the saw arm to its full up position.
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 counterclockwise.
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 securely clamped in the vise.
7. Proceed to cut according to instructions in
Cutting procedure.

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 blade-to-jaw angle.
1. Disconnect the saw from its electric power
source.
2. With the saw arm in its fully lowered position,
place a machinist's square,or a machinist's
protractor 90 degrees, against the saw blade
and right vise jaw. If the jaw is square 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.

9.3 Angle cutting

Refer to Figure 8.
1. Loosen the right jaw pivot and lock bolts.
2. With the arm in its fully lowered position, and
using a machinist's protractor between the saw
blade and right vise jaw, set the angle of the
right jaw to the required angle.
3. Tighten the pivot and lock bolts.
Figure 8: Using a protractor to set the vise jaws at
desired angle. By setting the protractor to 90
degrees, or using a machinist's square, the jaws
can also be set square with respect to the blade.
4. Lift the saw arm to its full up position and lock
it up using the hydraulic feed control knob.
NOTE: Use the handle on the arm to lift the
arm. Never use any other part of the arm as a
lifting method.
5. Loosen the left jaw lock bolt.
6. Use the handwheel to move the left jaw until it
touches the right jaw firmly.
7. Snug the left jaw lock bolt. Both vise jaws are
now the correct angle for the required cut.
NOTE: There is a scale on the back of the saw
table which allows you to set up for angle cuts
without using a protractor. See Figure 9.
These angles
approximate, and the protractor method should
be used where higher accuracy is required.
