CUTTING  WITh  YOUR  COMPOUND  MITER 
SAW

 

WARNING:

When using a work clamp or C-clamp to secure 
your workpiece, clamp workpiece on one side of 
the  blade  only.  The  workpiece  must  remain  free 
on one side of the blade to prevent the blade from 
binding in workpiece. The workpiece binding the 
blade will cause motor stalling and kickback. This 
situation could cause an accident resulting in pos-
sible serious personal injury.

 

WARNING:

To avoid serious personal injury, always tighten the 
miter  lock  handle  securely  before  making  a  cut. 
Failure to do so could result in movement of the 
control arm or miter table while making a cut.

TO CROSS CUT

See Figure 26.

A  cross  cut  is  made  by  cutting  across  the  grain  of  the 
workpiece. A straight cross cut is made with the miter table 
set at the 0

°

 position. Miter cross cuts are made with the 

miter table set at some angle other than zero.

  Pull out the lock pin and lift saw arm to its full height.

  Loosen the miter lock handle. Rotate the miter lock handle 

approximately one-half turn to the left to loosen.

  Press  the  miter  lock  plate  down  with  your  thumb  and 

hold.

  Rotate  the  miter  table  until  the  pointer  aligns  with  the 

desired angle on the miter scale.

  Release the miter lock plate.

left or right by releasing the lock plate as you rotate the 
control arm. The lock plate will seat itself in one of the 
positive stop notches,  located in the miter table base.

  Tighten the miter lock handle securely.

  Place the workpiece flat on the miter table with one edge 

securely against the fence. If the board is warped, place 
the convex side against the fence. If the concave edge 
of a board is placed against the fence, the board could 
collapse on the blade at the end of the cut, jamming the 
blade. 

See Figures 34 - 35.

  When cutting long pieces of lumber or molding, support 

the opposite end of the stock with a roller stand or with 
a work surface level with the saw table. 

See Figure 32.

  Align cutting line on the workpiece with the edge of saw 

blade.

  Grasp  the  stock  firmly  with  one  hand  and  secure  

it against the fence. Use the work clamp or a C-clamp to 
secure the workpiece when possible.

  Before turning on the saw, perform a dry run of the cutting 

operation just to make sure that no problems will occur 
when the cut is made.

  Grasp  the  saw  handle  firmly.  Depress  the  switch  lock 

with thumb then squeeze the switch trigger. Allow several 
seconds for the blade to reach maximum speed.

  Slowly lower the blade into and through the workpiece.

  Release the switch trigger and allow the saw blade to stop 

rotating before raising the blade out of workpiece. Wait 
until the electric brake stops blade from turning before 
removing the workpiece from the miter table.
