If Blade tracking requires adjustment:

1. 

Adjust Blade Speed to the slowest 86 FPM as described in the Blade Speed Belt/
Adjustment section of this Manual.

2. 

Raise the Cutting Head and rotate the Lock Lever Counter-Clockwise 90° down 
to a horizontal position locking it in the UP position.

3. 

Open the hinged Blade Guard by removing two Threaded Knobs and swinging it 
open. 

4. 

Check Blade Tracking:

  -  Blade should be very close to but not against the Idler Wheel Shoulder.  

  Also, the outer edge of the Idler Wheel should be even with the bottom of  
  the Blade teeth 

(FIG 31)

.  

  -  Close the Blade Guard.
  -  Run saw 30 seconds. 
  -  Stop, open Guard and observe Blade position on the Idler Wheel. 

5. 

If Blade is not tracking properly, adjust the Tracking by altering the Idler Wheel 
angle as follows: 

  -  Insert a 4mm Hex Key (Not Included) into the Tracking Set Screw 

(FIG 32)

.

  -  To move the Blade Tracking closer to Idler Wheel Shoulder; Turn the  

  Tracking Set Screw Clockwise.

  -  To move the Blade Tracking closer to the Idler Wheel outer edge; Turn the  

  Tracking Set Screw Counterclockwise.

6. 

If the above adjustments have corrected the tracking, retighten the Idler Wheel 
Spindle Bolts and re-check Tracking and repeat steps 4 & 5 if required.

7. 

When Tracking adjustment is complete; close and secure the hinged Blade Guard 
and return the Blade Speed to the desired setting.

  This adjustment is extremely sensitive! Turning the Tracking Set 

Screw a small amount will affect the Blade Tracking by a large 
amount! Turn the Tracking Set Screw in 1/4 turn increments only
 
and allow about 30 seconds of running to allow Blade to re-track.

INJURY HAZARD! 

  DO NOT RUN WITH REAR GUARD OPEN! Performing Tracking 

adjustments may cause the Blade to suddenly jump off the Wheels 
while running causing serious injury. 

  While performing the following steps, do not allow Blade to run 

excessively tight against the Idler Wheel shoulder. Excessive 
rubbing will damage wheel and/or Blade.
