The thrust bearing keeps the blade from moving back and out of position when the saw arm pushes against the 
workpiece. The thrust bearing must be very close to the back of the blade 

to prevent damage to the blade dur-

ing cutting. To adjust it, proceed as follows:

ADJUSTING THE THRUST BEARINGS

1.

   Shut off the hydraulic downfeed control valve and 

lift the arm into the vertical position. Loosen screw 

B

 

on bracket 

C

.

2.

   Push bracket 

C

 as shown 

D

 until the thrust bearing 

touches the back of the blade 

A

. Repeat for the 

other thrust bearing. 

Note: The blade guides must remain at least 1/32” behind 
the blade teeth to prevent damage to the blade as shown E.

MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORM-
ING ANY MAINTENANCE OR ADJUSTMENTS.

The blade guards should be adjusted based the di-
mensions of the workpiece.

To prevent the blade (which is flexible and which would 
not otherwise be supported) from slipping out of po-
sition during cutting, and to reduce risks of injuries, a 
minimum amount of blade should be exposed.

For a straight cut and to reduce the risk of twisting, loos-
en lock knobs

 as close as possible to the workpiece, then retighten 

the lock knobs.

 with a 12 mm wrench. 

2

.   Loosen the jam nuts

 and bolts 

M

 with a 12 mm 

wrench until the base of the motor can move.

3

.  Open the pulley cover and change the speed (re-

fer to the chart in the manual or the sticker inside 
the pulley cover). 

Note: if there is not enough slack to move the belt, loosen 
tension bolts M as needed. 

4

.   Retighten  bolts

 alternating until the belt tension 

is properly adjusted, then secure the motor in posi-
tion by tightening jam nuts

TIP: CHECK TENSION BY PUSHING THE BELT  WITH YOUR FIN-
GER. THE BELT SHOULD NOT MOVE MORE THAN 1/2”.
