ASSEMBLY

UNPACKING

This product requires assembly.

  Carefully lift saw from the carton by the carrying handle 

and the saw base, and place it on a level work surface. 

 

NOTE:

 This tool is heavy. To avoid back injury, lift with 

your legs, not your back, and get help when needed.

  This saw has been shipped with the saw arm secured in 

the down position. To release the saw arm, push down 

on the top of the saw arm, cut the tie-wrap, and pull out 

on the lock pin.

  Lift the saw arm by the handle. Hand pressure should 

remain  on  the  saw  arm  to  prevent  sudden  rise  upon 

release of the tie wrap.

  Inspect the tool carefully to make sure no breakage or 

damage occurred during shipping.

  Do not discard the packing material until you have care-

fully inspected and satisfactorily operated the tool.

  The  saw  is  factory  set  for  accurate  cutting.  After 

assembling it, check for accuracy. If shipping has influ-

enced the settings, refer to specific procedures explained 

in this manual.

  If  any  parts  are  damaged  or  missing,  please  call 

1-866-539-1710 for assistance.

personal injury.

 

WARNING:

Do not attempt to modify this tool or create acces-
sories not recommended for use with this tool. Any 
such alteration or modification is misuse and could 
result in a hazardous condition leading to possible 
serious personal injury.

 

WARNING:

Do not connect to power supply until assembly is 
complete. Failure to comply could result in acciden-
tal starting and possible serious personal injury.

 

WARNING:

Do  not  start  the  compound  miter  saw  without 
checking for interference between the blade and 
the miter fence. Damage could result to the blade 
if it strikes the miter fence during operation of the 
saw.

 

WARNING:

Always  make  sure  the  compound  miter  saw  is

workstand. Failure to heed this warning can result 
in serious personal injury.

MOUNTING hOLES

See Figure 8.

The  compound  miter  saw  should  be  mounted  to  a  firm  
supporting surface such as a workbench. Four bolt holes 
have been provided in the saw base for this purpose. Each 
of the four mounting holes should be bolted securely using  
3/8  in.  machine  bolts,  lock  washers,  and  hex  nuts  (not  
included). Bolts should be of sufficient length to accommo-
date the saw base, lock washers, hex nuts, and the thickness 
of the workbench. Tighten all four bolts securely.
The hole pattern for mounting to a workbench is shown in 
figure 8. Carefully check the workbench after mounting to 
make sure that no movement can occur during use. If any 
tipping, sliding, or walking is noted, secure the workbench 
to the floor before operating.
