BLADE CHANGING
We can not overstress the safety precautions which should be followed during this operation. Safety glasses,
gloves as well as a long sleeve shirt should be worn. The hydraulics should be off at all times when the operator
has his / her hands in contact with the blade. With safety in mind, the following procedure should be followed:
STEP ONE, Head Retract
Position the Head in the full retract position. This will drive the Head past the Head
Back Limit Switch creating a wider gap between the blade and the cutting table allowing
easier removal of the blade.
Press the HEAD RETRACT LIMIT OVER RIDE button on the operator panel.
STEP TWO, Open Doors
The blade on the V-18 II travels around two blade wheels, the bottom Drive wheel
and the top Idler wheel. Both of these wheels are housed in compartments with
locking doors. The photo shows the top Idler wheel with the door open.
STEP THREE, Open Blade Guard
The V-18 II 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.
STEP FOUR, Release Carbides
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
O counter
clockwise. The top carbide lever is shown in the photo. The bottom
lock lever is on the lower guide arm.
STEP FIVE, Blade Tension
To remove the blade the blade tension must be released. The Blade Tension selector
switch is a three position switch.The "+/RUN" position is for the normal operation of the
V-18 II.The " - " position is for releasing the tension and the switch must be in this
position to change the blade.
