OPERATION MANUAL
5.4 BLADE GUIDE ADJUSTMENT
The blade guides are set before the machine leaves the factory but may need to be adjusted
due to movement while shipping, or general wear and tear after long operation.
To adjust the support roller
1. Make sure that the blade is oiled and correctly
tensioned.
2. DISCONNECT MACHINE FROM THE POWER SUPPLY
3. Raise and lock the bow saw for easy access. Slide the
blade guides as close as possible together and lock in
place.
4. Loosen the cap screws (Fig.5.4) and adjust the blade
guide housing so the back of the blade just touches
the bearing, making sure the guide housing is not
tilted.
5. Tighten the cap screws.
NOTE:
To access the cap screws on the other blade guide
you will need to remove the two Phillips head screws
and move the limit switch and its bracket out of the way.

2. Loosen the lock nut on the top of eccentric bolt.

bearing and the casting, adjust the bearing, so it is
against the side of the blade. There should be no
clearance. (Fig. 5.6)
4. Tighten the lock nut making sure that the eccentric
bolt does not turn.
5. Adjust the other ball bearing guide on the housing.
6. Repeat steps 1-4 on the other set of ball bearing guides
on the opposite side of the saw bow.
