Angle Cutting; Clamping Methods - Jet J-3130 Operating Instructions And Parts Manual

Angle cutting

Refer to Figure 2.
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.
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 3.
These angles should be considered approxi-
mate, and the protractor method should be
used where higher accuracy is required.

Figure 2: 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.
Figure 3: Using the scale on the rear of the saw
base to set the jaws for angle sawing. Where the
edge of the right jaw crosses the scale an approxi-
mate angle cut can be made to the indicated
number of degrees on the scale.

Clamping methods

The method for clamping different cross-
section work pieces is shown in Figure 4.
