BLADE CHANGING PROCEDURE
NOTE: Wear gloves for protection from the sharp blade.
1. Raise the head 4” off the table at the datum jaw, and swing to 60 °. Open the blade door.
2. Loosen the Blade Tensioner by turning counter clockwise.
3. Loosen the carbide tension handles by turning counter clockwise ¼ turn.
4. At the top of the head, the saw blade runs in behind two blade retainers. Grip the blade at each end of these
retainers and twist the blade teeth down past each and slide the blade forward. Let the blade rest, and then
slide the blade down and out of the carbide guides.
5. Your new blade will be in a coil. While wearing gloves, hold the blade away from yourself, and twist the blade
to uncoil it. Do not let the blade teeth bounce on the concrete floor as this may cause some damage.
6. Place the new blade in the carbide guides and then slide the blade over the wheels. The teeth should be
pointing towards the drive side as they pass through the carbide guides.
7. With the blade in place, turn the tensioner handle clockwise. Recommended blade tension is between 1000 -
1200 kg (2200 - 2650 lbs). If the blade is under tensioned the blade motor will not start.
8. Turn the two carbide-locking handles clockwise to the locked position.
BLADE TRACKING ADJUSTMENT
1. Jog the blade a few rotations to check that the blade is not moving in or out on the blade wheels. NOTE: As
the blade tracking will stay fairly constant, it should be checked occasionally as shown on the drive wheel-
tracking photo below. The blade teeth should protrude from .185” to .200” (4.7 - 5.1mm) from the face of the
blade wheels. If the tracking requires adjustment, follow the instruction below.
2. BLADE TRACKING ADJUSTMENT – First, inspect the blade wheels for wear or damage and repair as re-
quired. Blade tracking adjustment should always begin at the wheel where the tracking is farthest out of speci-
fication. Using the instructions below, adjust the worst wheel, jog the blade and recheck both wheels. Repeat
this process until both wheels are within specification.
a. IDLER WHEEL ADJUSTMENT
Remove the Idler Box Front Cover to access the Blade Tension Slider Assembly
The tracking is adjusted by regulating the “push” set screws and the “pull” hex bolts. Before making any
adjustments, bolts A & B should be loosened but remain snug. This will allow easy movement for the
slide assembly. Loosening bolt A and turning in set screws C by equal amounts will move the blade on to
the wheel. Loosening bolt B and turning in set screws D by equal amounts will move the blade off of the
wheel. After each C or D adjustment, tighten bolts A & B, run the blade and then check the tracking.
