Adjusting Upper Thrust Bearing

1. NOTE: The thrust bearing supports the blade 

from  the  rear  and  will  rotate  when  the  blade

is pushed against it while you are cutting. As 

soon  as  you  stop  cutting,  the  bearing 

should stop rotating.

2. To adjust, loosen the upper screw on the side 

of  the  upper  blade  guide  assembly  and  slide 

the  bearing  forward  until  it  is  approximately 

1/32"  from  the  back  of  the  blade.  Tighten 

screw. Rotate upper wheel slightly clockwise 

to check clearance. Re-adjust if necessary.

Adjusting Lower Blade Guide Assembly

*      Loosen  the  screw  (as  shown)  on  the  side  of the 

lower  blade  guide  assembly  and  slide  assembly 

forward  until  bearing  is  approximately  1/32" 

from  the  back  of  the  blade.  Blade  guides  will 

align with this adjustment. Tighten screw.

Adjusting Lower Blade Guides

*   Loosen the two screws that lock the lower blade 

guides  and  press  the  two  guides  evenly  against 

the  sides  of  the  blade  but  do  not  pinch  the 

blade.  Release  the  guides  and  rotate  the 

upper  wheel  slightly  clockwise  moving  the 

blade  downward.  Make  sure  one  guide  is  not 

further  away  from  the  blade  than  the  other. 

Tighten both screws.

NOTE: After all adjustments have been made, turn the wheel by hand (clockwise) a few turns to 

check blade travel and clearance. (As diagram shown in paragram "Ten-sioning the blade")

Adjusting The Table

1.    Replace  the  blade  guard  on  the  upper  assembly 

and tighten screws.

2.  Locate the table insert and place it in the opening 

in  the  table.  Aiiyn  slot  in  the  insert  with  the  slot 

in the table.

3.   Locate  a  1/4 - 20  x  3/4" truss  head  screw,  a f l a t

washer,  and  a  1 / 4 - 2 0 wing  nut  in  loose  parts. 

Insert screw into hole in table top as illustrated.

4.  From the underside of the table, install washer 

and wing nut onto the truss head screw and tighten finger tight. This will keep the table flat 

and in alignment.

5.  Replace the band saw cover.

Mounting Band Saw To Workbench

If band saw is to be used in a permanent location, it 

should  be  fastened  securely  to  a  firm  supporting 

surface such as a workbench.

If mounting to a workbench, holes should be • 

drilled   through   supporting   surface   of  the 

workbench    using    dimensions    illustrated.

1.  Each  leg  should  be  bolted  securely  using  3/8" 

diameter  machine  screws,  lock-washers,  and 

3/8" hex nuts (not included).

2.   Locate and mark the holes where band saw is 

to be mounted.

3. Drill (4) —

<b 

11 diameter holes through 

workbench.

4. Place band saw on workbench aligning holes in feet with holes drilled in workbench.

5.  Insert all four 3/8" screws and tighten.

NOTE:   Front two mounting bolts should be inserted from the bottom with washer

and nut on top.

An  alternate  method  of  mounting  is  to  fasten  band  saw  to  a  mounting  board.  The  board 

should be of sufficient size to avoid tipping of saw while in use. Any good grade of plywood 

or  chipboard  with  a  3/4"  minimum  thickness  is  recommended.  (Thinner  chipboard  can 

break.)
