Are both sets of blade guides identical?

To adjust the carbides, follow the steps below:

Loosen the set screws in the handle bases and remove the handles

Under the handles, are there large hubs with a flat on each side and a socket head cap screw inside the center?

Are the screws holding the carbide pads in place?

Adjust the position of the carbide pads by turning the hubs clockwise to tighten the pads on the blade

Are the hubs tightened against the blade, backed off 1/16 to 1/8 of a turn?

Is the handle installed in the LOCKED position and the set screws tightened?

Release blade tension before adjusting

Adjust tracking by regulating 'push' set screws and 'pull' bolts

Loosening bolts 'A' and turning in setscrews 'C' by equal amounts will move the blade OFF the wheel

Loosening bolts 'B' and turning in sets crews 'D' by equal amounts will move the blade ON to the wheel

After each 'C' or 'D' set screw adjustment, tighten bolts 'A' or 'B', turn tension switch to '+RUN', run the blade for a moment and recheck the tracking

Release blade tension before adjusting

Loosening bolts 'A' and turning in set screws 'C' by equal amounts will move the blade OFF the wheel

NOTE: Wear gloves, safety glasses and a long sleeve shirt for protection from the sharp blade. The hydraulics should be OFF any time the operator has his/her hands in contact with the blade.

Select MANUAL mode and raise the head so the drive door will clear the electrical control panel.

Release the blade tension by turning the Blade Tension Switch to '-'.

Shut the machine off and open the idler and drive doors.

Loosen the carbide locking levers by turning counter clockwise 1/4 turn.

At the top of the head, the saw blade runs in a protective channel. Grip the blade at each end of this channel and twist the blade teeth down past the channel and slide the blade forward. Let the blade rest on the out feed table, then slide the blade down and out of the carbide guides.

Before installing the new blade, check that it measures 1.615' wide including the teeth. Some blade manufacturers supply blades that measure 1.5' including the teeth. The same applies to 2' blades, they should measure 2.120'. In this case you may not be able to adjust the head down limit to complete the cut.

Your new blade will be in a coil. While wearing gloves, hold the blade away from yourself, twist the blade to uncoil it. Do not let the blade teeth bounce on the concrete floor as some damage to the blade may be caused.
