  Blade Replacement 

A general-use variable-tooth blade is provided with 
this band saw.  
Choice  of  blade  pitch  is  governed  by  thickness  of 
workpiece:  the  thinner  the  workpiece,  the  more 
teeth advised. A minimum of 3 teeth should engage 
workpiece at all times. If blade teeth are so far apart 
that  they  straddle  the  work,  severe  damage  to 
workpiece and blade can result. 
1)  Disconnect the machine from the power source. 
2)  Raise the bow to the vertical position. 
3)  Open  the  rear  guard  by  removing  the  two  (2) 

knobs (see Figure 8-8). 

4)  Remove  the  red  guard  from  the  upper  blade 

guide by removing two (2) screws. 

 It is essential that red blade 

guard be installed after new blade has been 
fitted. Failure to comply may cause serious 
injury.

 

5)  Release  tension  on  the  blade  by  turning  the 

tension 

handle 

(P, 

Figure 

8-5) 

counterclockwise. Remove blade. (Use gloves 
when handling sharp blades). 

6)  Install the new blade between the blade guide 

assemblies and around each wheel. Make sure 
blade teeth are pointing in the proper direction. 
See Figure 8-6.  

 

Figure 8-6 

7)  Increase blade tension just enough to hold the 

blade on the wheels. Make sure the back of the 
blade rests lightly against the shoulder of both 
wheels. Twist the blade slightly to allow it to slip 
into the guides. 

8)  Install red blade guard with screws. 
9)  Tension  blade  fully  (see 

sect.  8.8  Blade 

Tension.)

 

10)  Place  two  to  three  drops  of  lightweight  oil  on 

blade. 

11)  Adjust  blade  guide  bearings  (see 

sect.  8.6 

Blade Guide Bearings).

 

12)  Connect machine to power source. 
13)  Run  saw  and  make  sure  blade  is  tracking 

properly (

sect 8.9. Blade Tracking.

14)  Follow blade break-in procedures 

(sect. 9.1).

 

8.6

  Blade Guide Bearings 

1)  Disconnect the machine from the power source. 

2)  Loosen the bolt (Q, Figure 8-9) and adjust the 

assembly  so  that  the  rear  bearing  (R

1

)  is 

approximately  0.002  to  0.003  inches  from  the 
back of the blade. Also, the inside bearing (R2) 
should  very  lightly  contact  the  blade.  Tighten 
bolt (Q). 

3)  Inside bearing (R

2

) is fixed. Outside bearing (R

3

rotates on an eccentric shaft. Rotate the nut (S) 
with  a  14mm  wrench  to  adjust  the  eccentric 
bearing to a clearance of 0.001 inches from the 
blade. 

4)  Repeat  above  steps  for  the  opposite  blade 

guide assembly. 

 

Figure 8-7:  Blade Guide Setting 

8.7

  Chip Brush 

The wire chip brush must be properly adjusted and 
maintained in working condition, otherwise damage 
to  the  blade  can  occur.  Adjust  brush  so  that  its 
bristles  overlap  the  blade.  Replace  brush  if  it 
becomes worn or damaged. 

8.8

  Blade Tension 

1)  Disconnect the machine from the power source. 

2)  Open  the  rear  guard  by  removing  the  two  (2) 

knobs (see Figure 8-8). Observe the position of 
the blade on the wheel. If blade is not adjacent 
to  wheel  flange, first  adjust  the  blade  tracking 
according to 

sect. 8.9 Blade Tracking.

 

3)  If  blade  is  properly  adjacent  to  wheel  flange, 

slide  blade  guide  assemblies  as  far  apart  as 
possible, and tighten in position with knobs (N, 
Figure 8-5). 

4)  Push  on  the  blade  to  test  tension.  Finger 

pressure  should  cause  approximately  0.004" 
deflection.  Turn  the  blade  tension  handle  (P, 
Figure 8-5) until proper tension is achieved. For 
more precise measurement use a blade tension 
gauge (not provided). 

5)  Return blade guides to operating position.
