To change the cutting angle, follow the procedure below: 

1. 

Loosen the two hex bolts. 

2. 

Set the guide plate to the desired angle (0° - 45°). 

3. 

For  more  accurate  angle,  use  a  protractor  or 
triangle  ruler.  Keep  the  handle  down  so  that  the 
cut-off  wheel  extends  into  the  base.  At  the  same 
time, adjust the angle between the guide plate and 
the cut-off wheel with a protractor or triangle ruler. 

4. 

Tighten the hex bolts securely. At this time, make 
sure that the guide rule does not move. 

5. 

Check the angle again. 

 

CAUTION: 

• 

Never perform right miter cuts when the guide plate 
is set at the 35 - 205 mm or 70 - 240 mm position. 

NOTE: 

• 

The  scale  on  the  guide  plate  is  only  a  rough 
indication. 

ASSEMBLY 

 

CAUTION: 

• 

Always  be  sure  that  the  tool  is  switched  off  and 
unplugged before carrying out any work on the tool.

To remove the wheel, raise the wheel guard. Press the 
shaft lock so that the wheel cannot revolve and use the 
socket  wrench  to  loosen  the  hex  bolt  by  turning  it 
counterclockwise.  Then  remove  the  hex  bolt,  outer 
flange and wheel. (Note: Do not remove the inner flange, 
ring and O-ring.) 
To  install  the  wheel,  follow  the  removal  procedures  in 
reverse.

CAUTION: 

• 

Be sure to tighten the hex bolt securely. Insufficient 
tightening of the hex bolt may result in severe injury. 
Use  the  socket  wrench  provided  to  help  assure 
proper tightening. 

• 

Always use only the proper inner and outer flanges 
which are provided with this tool. 

• 

Always  lower  the  wheel  guard  after  replacing  the 
wheel. 

Securing workpiece

By  turning  the  vise  handle  counterclockwise  and  then 
flipping the vise nut to the back, the vise is released from 
the shaft threads and can be moved rapidly in and out. To 
grip workpieces, push the vise handle until the vise plate 
contacts the workpiece. Flip the vise nut to the front and 
then turn the vise handle clockwise to securely retain the 
workpiece. 

 

CAUTION: 

• 

Always  set  the  vise  nut  to  the  front  fully  when 
securing the workpiece. Failure to do so may result 
in insufficient securing of the workpiece. This could 
cause  the  workpiece  to  be  ejected  or  cause  a 
dangerous breakage of the wheel. 

When the cut-off wheel has worn down considerably, use 
a spacer block of sturdy, non-flammable material behind 
the  workpiece  as  shown  in  the  figure.  You  can  more 
efficiently utilize the worn wheel by using the mid point on 
the periphery of the wheel to cut the workpiece.

003987 

When cutting workpieces over 85 mm wide at an angle, 
attach a straight piece of wood (spacer) to the guide plate 
as  shown  in  the  figure.  Attach  this  spacer  with  screws 
through the holes in the guide plate.
