BLADE CHANGE PROCEDURE
Wear safety glasses, gloves, and a long sleeve shirt for protection when handling bandsaw blades during blade change.
NOTE THAT GLOVES SHOULD NEVER BE WORN NEAR A RUNNING BANDSAW BLADE.
When handling new blades, or ones that will be re-used, it is important to keep the teeth out of contact with concrete
oors.
All machines with hydraulic blade tension are equipped with a ‘Blade Change Mode’ key switch, located at the operator
control panel.
This key switch has 2 positions:
OFF = All normal operations of the band saw are operative.
ON = Hydraulic motor can be started.
Blade Tension is operative.
All other hydraulic functions and blade start are inoperative.
1. Select MANUAL mode and raise the head so the blade can clear both the movable and xed jaws.
2. Turn the blade change key switch to the ‘ON’ position. The hydraulics will continue to run, but only the Blade Ten-
sion Switch is functional.
3. Open the idler and drive doors.
4. Turn the Blade Tension Switch from the TIGHTEN position “ +/RUN”, through the unmarked central HOLD posi-
tion, and briey to the LOOSEN position “ – “
• By jogging the switch between hold and loosen, it is possible to regulate the degree of looseness of the
blade. It is helpful to have the blade just loose enough that it stays on the wheels and in the blade guides,
but can be manually pulled off the wheels and out of the guides.
5. 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,
and slide the blade down and out of the carbide guides.
6. Before installing the new blade, check that it measures 1.345” wide including the teeth. Some blade manufactur-
ers supply blades that measure 1.25” including the teeth. Otherwise, you may have to adjust the head down limit
to complete the cut.
7. Your new blade will be in a coil. While wearing gloves hold the blade away from you, twist the blade to uncoil it.
Do not let the blade teeth bounce on the concrete oor as some damage to the blade may be caused.
