IMPORTANT:  Before tracking the blade, confirm that 

the blade guides and blade support bearings are clear 

of the blade.

•  After applying tension to the blade, open the upper 

wheel guard.

•  Rotate the wheel slowly forward by hand and observe 

the blade’s movement. It should travel in the center of 

the upper tire. 

•  If the blade creeps toward the front edge, unlock the 

blade tracking lock (A) and turn the blade tracking 

knob (B) clockwise until the blade consistently tracks 

in the middle of the tire. 

•  If the blade creeps towards the rear of the tire, adjust 

the blade tracking knob counterclockwise. 

•  Lock the blade tracking lock and close and lock the 

upper wheel guard. 

•  Fit the throat plate (A) in the throat of the table so that 

the tab on the throat plate fits into the notch in table. 

•  Check to ensure the front of the throat plate is not 

higher than the table surface. To adjust the height of 

the throat plate, rotate the two set screws (B) either 

up or down

Place a carpenters square (A) against the front and 

back side of the blade and check the alignment of the 

table. If the table is out of square, refer to Figure 11 and 

proceed as follows: 

•  Raise the upper blade guide assembly by loosening 

the lock knob (B).

•  Loosen the flange nut (C) on the lower trunnion using 

a 12MM open end wrench and adjust the set screw 

until the table is square with the blade from the front 

and back.

•  Tighten the flange nut and use the square to confirm 

proper position of the table 

•  Check the pointer on the tilt scale, located on the 

lower trunnion, and reset if necessary to read 0°.
