Limit Switch Adjustment; Operations; Starting The Saw - Jet J-7060 Operating Instructions And Parts Manual

5. Rotate the bar stock 180 degrees so that the
mark you made is now at the bottom of the cut.
6. Make a cut through the bar stock.
7. Use a micrometer to measure the thickness
variation of the disk you have cut from the bar
stock. Measure at the top and bottom of the
disk. The saw blade can be considered
correctly adjusted when the variation measure
is no more than 0.012 inch across the face of
the disk.
Note: If you do not have a piece of 2-inch bar stock
available for a test cut, use a larger diameter test
piece rather than a smaller one. Maximum thickness
variation on any test piece should be no more than
0.003 inch, per side, per inch of stock diameter.

9.4 Limit switch adjustment

9.4.1 Adjustment of lower limit switch
The lower limit switch is provided to shut off the saw
blade drive motor when the workpiece is cut
through. The switch causes the saw head to raise to
its uppermost stop.
To set the limit switch, loosen jam nut on stop bolt
(Figure 12). Turn stop bolt with a wrench as required
and retighten jam nut.
9.4.2 Adjustment of lower limit switch
The upper limit switch is provided to stop the saw
head when it reaches its uppermost stop.
To set the upper limit switch, loosen the clamping
knob on the limit switch support bracket. Move the
limit switch to the desired switch trip point (use the
scale on the side of the support bracket).

10.0 Operations

10.1 Starting the Saw

Never operate saw without
blade covers in place and secured.
Make sure blade is not in
contact with workpiece when motor is started.
Do not drop saw head on workpiece or force the
blade through the workpiece.
1. Raise saw head.
2. Clamp workpiece in vise. (See Figure 13 for
examples of workpieces in the vise.)
3. Be sure to start blade drive motor before
allowing blade to contact workpiece.
4. Start motor and allow saw to come to full speed.
5. Slowly bring saw head down onto workpiece.
6. Adjust feed rate using feed rate control.
7. DO NOT LOWER THE SAW HEAD AT A RATE
FASTER THAN THE SAW'S CAPABILITY, OR
FORCE THE CUT. Adjust feed rate so the
hydraulic cylinder provides the proper amount
of downward force.
8. The saw will automatically shut off at end of
