  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

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 

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

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.
