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 opera-
tor 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.
BLADE REMOVAL
1. With the Blade Change Mode key switch in ‘OFF’, the blade stopped and the hydraulics
ON, retract the saw head in the full retract position. Press the HEAD RETRACT LIMIT
OVERRIDE button and turn the head control switch to retracted on the operator panel.
This will drive the Head past the Head Back Limit Switch creating a wider gap between
the blade and cutting table allowing easier removal of the blade.
2. Turn the blade change key switch to the ‘ON’ position.
• Hydraulics will continue to run, but only the Blade Tension Switch is func-
tional. The blade wheel doors can be opened without the hydraulics shutting
down.
3. The V18 blade is only exposed to the operator at the cutting area. A
hinged cover protects the operator from the blade between the Idler
wheel assembly and the actual cutting area. A black knob on the cover
allows it to be easily pulled open.
4. It is necessary to release the carbides from the locked position so that
the blade can be easily removed. As shown in the photo the carbides are
released by turning the lock bars 270 degrees counter clockwise. The top
carbide lever is shown in the photo. The bottom lock lever is on the lower
guide arm.
5. Turn the Blade Tension Switch from the TIGHTEN position ( < + > ),
through the unmarked, central HOLD position, 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 help-
ful to have the blade just loose enough that it stays on the
wheels and in the blade guides, but can be manually pulled
o the wheels and out of the guides.
6. Pull the blade forward out of the slot on the inside walls of the blade
wheel housings and out of blade guides.
7. Store or dispose of the used blade.
