TRACKING THE BLADE

Disconnect the machine from the power source!

IMPORTANT: Before tracking the blade, confirm that

A

the blade guides and blade support bearings are clear

 

of the blade.

 

After applying tension to the blade, rotate the wheels

 

slowly forward by hand and observe the blade’s

 

movement. The blade (A) Fig. 31 should travel in the

 

center of the upper tire. If the blade creeps toward the

 

front edge, loosen the wing nut (B) Fig. 32 and turn the

 

thumb screw (C) clockwise. This action draws the blade

 

toward the center of the tire. If the blade creeps toward

Fig. 31

the back edge, turn the thumb screw in the opposite

direction. Adjust the thumb screw (C) Fig. 32 only a

 

fraction of a turn each time.

Never track the blade while the machine

 

is running.

 

After the blade is tracking in the center of the tires,

 

tighten the wing nut (B) Fig. 32.
