The blade guard closed and open
with the carbide locking lever in the
locked position.
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. Pull the head
back adjustment lever out and then press the head retract push button. This
will drive the head past the Head Limit Switch creating a wider gap between
the blade and the 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 functional. The blade wheel doors can be opened
without the hydraulics shutting down.
3. The V18 APC 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 “+/RUN”,
through central HOLD position, and briefly 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.
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.
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
floors.
All machines with hydraulic blade tension are equipped with a ‘Blade Change Mode’ key switch,
located on 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.
