7.0 OPTIONAL EQUIPMENT
7.1 POWER VISE
The power vise is an option that is normally ordered with the saw. A retrofit kit is available from your
local dealer or the factory. The kit includes all parts required, plus complete installation instructions.
The power vise allows automatic clamping of the material, which improves productivity and reduces
operator fatigue. The vise automatically clamps when the saw head is drawn down and releases when the
saw head returns.
7.1A POWER VISE SET-UP AND MAINTENANCE
SEE FIGURE 12 ON THE FOLLOWING PAGE.
THE FOLLOWING ARE SET-UP AND MAINTENANCE INSTRUCTIONS FOR THE POWER VISE
OPTION (RETROFIT OR FACTORY INSTALLED):
1. Before connecting the air supply to the saw, make sure that the filter/lubricating device (A) is full
of oil.
2. Slide the shuttle valve (F) on the filter/lubricator device to the closed position.
3. Connect the air supply to the shuttle valve. Make sure that the vise is clear and that the head is in
the UP position.
4. Slide the shuttle valve in to open the valve. Whenever the shuttle valve is closed, it bleeds the air
pressure out of the system automatically.
5. Adjust the air pressure regulator (G). 90 PSI (6.2 BAR) is the minimum operating pressure. 105
PSI (7.2 BAR) is the maximum.
6. Before powering the saw, pull the head down several times, to make sure that the four way valve
(H) and the lubricating device (A) are adjusted properly and the air pressure setting remains
constant.
7. The four way valve should activate the vise at the beginning of the down stroke and release it at
the top of the return stroke. The four way valve is adjusted with the set screw (B) in the valve arm
just above the roller.
8. The lubricating device (A) should release one drop of oil every 5 to 10 cycles of the head. On top
of the lubricating device is a clear plastic dome with a small tube inside. The oil should drop out
of the tube. The lubricating device is adjusted by turning the knob (C) on the top of the lubricator.
9. To add oil to the lubricating device, disconnect the air supply and remove the plastic bowl. The
bowl is threaded and unscrews from the body. Fill the bowl approximately 3/4 full of oil designed
or air lubricators and screw it back on the lubricator.
