Figure 9: 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
approximate angle cut can be made to the
indicated number of degrees on the scale.
9.4 Clamping methods
The method for clamping different cross-section
work pieces is shown in Figure 10.

sections of stock
9.5 Using the stock stop
When cutting a number of identical pieces, the use
of the stock stop can speed operations.
Refer to Figures 1 and 11.
1. Disconnect the saw from its electric power
source.
2. With the arm in its fully lowered position,
loosen the stock stop set screw.
3. Slide the stock stop to the required distance
from the blade.
4. Rotate the stock stop so the stop is at the
lowest possible position for stopping the work
piece at the required distance. This will help
prevent any binding between the work piece
and blade when the cut is completed.
5. Tighten the stock stop set screw securely.
6. For best accuracy, make a test cut on a piece
of scrap material to verify the length of cut
using the stock stop.

9.6 Blade selection
The saw is delivered with a blade adequate for a
variety of jobs on a variety of common materials.
However, JET's blades, while appropriate to many
shop cutting needs, don't begin to exhaust the wide
variety of special blades available for special
cutting jobs.
For high production cutting of special materials, or
for hard-to-cut materials such as stainless steel,
tool steel, titanium, etc., ask your industrial
distributor for more specific blade
recommendations.

Table 2: Recommended blade speeds
9.7 Changing blade speeds
1. Refer to Table 2 for recommendations on
blade speed for various materials.
Note: These are approximate speeds.
Different alloys and section materials and the
use of cutting fluid may require other speeds.
Check your machinists' handbook, or ask for
recommendations from your blade, cutting fluid
or work piece suppliers for specific
recommendations on specific material.
