Features

Miter Cutting Head
The miter cutting head is the unit that cuts the material and c onsists of a cast i ron 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 mechani sm overrides the lock, permitti ng the head to adjust to any position between -45º and +45°.
Figure 1
Miter Position Lock
The miter position lock sec ures t he mi ter cu tti ng head from movement. The miter is secured when the lock is pushed all the way to the left and can be positioned when the l oc k is moved to the right.
Self-centering Vise
The self-centering vise holds the work piece in place during c utting. The work piece is secur ed in the vise by turning the vis e handles .
Blade Lock
The blade lock secures the arbor from rotation when attempting to change blades. The blade lock is pushed in when changing bl ades.
The blade lock is not spring loaded and must be pulled out after the blade has been replaced and before operating the machine.
Controls
Mist Coolant System
The mist coolant system sprays a coolant mist onto the saw blade duri ng the cutting operati on, 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. W hen the head is moved off of the top limit switch (Figure 2) when beginning a cut, the pneumatic switch (B) is activated, allowing air t o flow through t he 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 r ecommended brands are DoAll and Lenox. These coolant s are available at your local industrial distributor.
The cont rol panel c onsist s 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 swi tc h m ust be se t fo r Hi or Low. Then depr ess the tr igger handle to start.
Trigger Handle
The trigger handle (Figure 1) is located on the operating lever used to rai se and lower the saw.
It contains a micro-switch, which is activated when the operator depres se s the r un trigger.
