Adjusting Blade Square to table 

 
Refer to Fig 19. 
 
The  settings  on  your  band  saw,  such  as  blade 
squareness  and  tracking,  were  carefully  performed  by 
the  manufacturer.  You  should,  however,  verify  these 
before  operating,  in  case  misalignment  has  occurred 
during shipping. 
 

1.

 

Disconnect machine from the power source. 

2.

 

Place  machinist’s  square  on  the  table  next  to  the 
blade as in Figure 19. 

3.

 

Check  to  see  blade  makes  contact  with  the  square 
along the entire width of the blade. 

4.

 

If  adjustment  is  necessary,  loosen  bolt  (A,  Fig.  19) 
and  rotate  blade  guide  assemblies  slightly  in  the 
same  direction  until  blade  makes  contact  with  the 
square along its entire width. 

5.

 

Tighten bolt (Fig. 19). 

6.

 

Connect machine to the power source. 

NOTE:  If  adjustment  of  squaring  blade  to  table  was 
necessary, re-verify all other blade adjustments.

Adjusting Blade Square to Vise 

 
Refer to Fig. 20/21 
 

Squaring blade to vise 

1.

 

Disconnect machine from the power source. 

2.

 

Place a machinist’s square as pictured in (A, Fig. 20) 
square  should  lie  along  entire  length  of  vise  and 
blade without a gap. 

3.

 

If  adjustment  is  necessary,  loosen  saw  frame  lock 
bolts  and  swiveling  saw  frame  to  match  with  vise 
square  so  that  square  lines  up  properly.    Tighten 
lock bolts. 

4.

 

Retighten the lock handle. (B, Fig. 21) 

5.

 

Connect machine to the power source.
