7.0 Features

7.1 Miter Cutting Head

The miter cutting head is the unit that cuts the material and consists of a cast iron base, blade support unit and guard, transmission unit, and motor. The depth of cut is set by adjusting the depth cut stop. The miter cutting head swivels and locks into -45º, 90º, and +45º by means of a locking mechanism. Depressing the mechanism overrides the lock, permitting the head to adjust to any position between -45º and +45.

Figure 1

7.2 Miter Position Lock

The miter position lock secures the miter cutting head from movement. The miter is secured when the lock is pushed all the way to the left and can be positioned when the lock is moved to the right.

7.3 Self-centering Vise

The self-centering vise holds the work piece in place during cutting. The work piece is secured in the vise by turning the vise handles.

7.4 Blade Lock

The blade lock secures the arbor from rotation when attempting to change blades. The blade lock is pushed in when changing blades.

The blade lock is not spring loaded and must be pulled out after the blade has been replaced and before operating the machine.

7.5 Controls

7.7 Mist Coolant System

The mist coolant system sprays a coolant mist onto the saw blade during the cutting operation, cooling it and the work piece being cut. Air is supplied from a compressor to the air intake valve (A) located near the bottom of the cabinet on the left side. When the head is moved off of the top limit switch (Figure 2) when beginning a cut, the pneumatic switch (B) is activated, allowing air to flow through the air tube (C) and into the orifice (not shown), causing coolant to be drawn through the coolant tube (D). The pneumatic valve (E) adjusts the amount of airflow. Air and coolant is mixed in the orifice and sprayed onto the saw blade.

Use a water-soluble synthetic coolant with this mist coolant system. The ratio should be between 7:1 to 10:1. Coolant should be changed regularly. Some recommended brands are DoAll and Lenox. These coolants are available at your local industrial distributor.

The control panel consists of the Power (On/Off) switch and High/Stop/Low switch, and an integral coolant system. To operate the machine, the Power switch must be set to On and the High/Stop/Low switch must be set for Hi or Low. Then depress the trigger handle to start.

7.6 Trigger Handle

The trigger handle (Figure 1) is located on the operating lever used to raise and lower the saw. It contains a micro-switch, which is activated when the operator depresses the run trigger.
