Excalibur 6000 user guide – Maintenance
Do not wipe the Squaring Arm channels or remove any debris with fingers, as it may contain sharp particles such as glass.
Use a vacuum cleaner if possible. If a soft brush is used, work slowly and do not allow particles to flick off the bristles.
Guide rods and rollers:
Wipe using cleaning solvent on a cloth, and lubricate the surfaces very lightly with petroleum jelly. The axles of the rollers are lubricated and sealed for life and need no further attention.
Ratchet system:
Use a light oil (3 in 1), one or two drops on the pivot point and one drop on the ratchet teeth.
Balance weight:
Silicon Lubricant sprayed in from the top of the balance weight opening whilst the Twin Wheel Cutting Head is parked at the bottom of the machine.
Ratchet release bar:
Smear edge with petroleum jelly.
Swinging Arm:
Petroleum jelly around curved slot.
The Cutting Head slides up and down on two stainless steel Guide Rails (1) that are
embedded into the Slideway (2). There are four grooved Guide Wheels that run on the
rails, where the two furthest away are fixed (3) and the two closest are adjustable (4). The screws that the adjustable Guide Wheels run on are eccentric and move the wheels into or away from the rail as they are rotated. These
Guide Wheels are adjusted in the factory and should not under normal circumstances
require re-adjustment. However, the adjustment check and procedure is defined in the
event that either Cutting Head needs to be removed for any reason.
Move the head to a comfortable height and lock the respective cutting head’s position using the white nylon locking screw. Ensure that this is done tightly.
If the head falls under its own weight, use a 1.5mm tip flathead screwdriver to tightly fasten the cutting head to the machine.
Using a 13mm spanner on the locking nut and a 5mm spanner (or grips) on the square end of the eccentric screw, hold the eccentric screw still and loosen the locking nut by about half a turn.
To readjust the Guide Wheels, rotate the eccentric screw clockwise until resistance is felt and there is no wobble experienced on the head, when moved side to side.
When the appropriate amount of resistance has been applied to the both Guide Wheels in the respective cutting heads, hold the eccentric screw still and tighten the locking nut securely. Loosen the white nylon locking screw and test again to see that there is no wobble present on the head.
The pressure of the clamp is in relation to the amount of pressure applied to the operating handle, however in time the maximum clamping pressure can reduce due to wear on the friction black (hidden within the machine). Compensation for this can be made by adjusting the two small grub screws in the operating handle housing as shown. Turning the screws lightly clockwise until they stop moving and then undoing them by quarter of a turn should provide an acceptable pressure, but further small adjustments can be made to increase or decrease the pressure as required.
The Blue Support Boards on the spine and support arms offer an element of protection to materials being cut, in particular coated glass surfaces. Over the machine’s lifetime it could be expected that these Blue Support Boards could experience wear and so the procedure to replace these elements are defined below.
Removing from the support arm:
Slightly pry the edge of the Blue Support Board using a thin and rigid item such as a ruler. Peel the layers of double sided tape from the support arm if any tape remains on the surfaces. Clean the surface of the support arm with white spirit to clear any remnants of adhesive.
Placing onto the support arms:
Peel the paper layer off the double sided tape and align the angled face of the board with the angled face of the support arm that does not have the end cap attached.
Proceed to lower the Blue Support Board onto the support arm surface, starting from the aligned edge.
Brush your finger gently across the edge of the respective support arm’s Blue Support Board to peel off the protective film.
Removing from the main body:
Loosen the two screws using the 6mm Allen key (hex key) on the mount plate of the machine, as indicated. The left hand one needs to be undone enough for the flanged washer (A) to be lifted clear of the top plate, or it can be entirely removed if you prefer but do not remove the other screw. Repeat this at the bottom end of the machine.
Lifting the flanged washer clear with one hand, take hold of the slideway and twist it out as shown. Once the flanged washer is clear of the top plate it can be released. It is normal to feel the balance weight cord working against you.
You will feel the balance weight cord (A) working against you and try to twist the slideway back, open the slideway carefully and watch that the balance weight cord (A) does not become trapped. Tighten the bottom Allen screw (B), as shown, to hold the slideway open in the maintenance position.
With the Blue Support Board now accessible, slightly pry the edge using a thin and rigid item such as a ruler. Peel the layers of double sided tape from the main body if any tape remains on the surfaces. Clean the surface of the main body with white spirit to clear any remnants of adhesive.
Placing onto the main body:
Peel the paper layer off the double sided tape and align the angled face of the board with the angled face of the spine that does not have the end cap attached. Ensure that the flat face identified is also aligned with the face of the main body.
Proceed to lower the Blue Support Board onto the main body, starting from the aligned edges.
Brush your finger gently across the edge of the respective support arm’s Blue Support Board to peel off the protective film.
Proceed to return the slideway back into operating position and ensure that the cutting head runs up and down the full length of the slideway. Fasten the respective screws tightly.
Move the head to a comfortable height and lock the respective cutting head’s position using the white nylon locking screw. Ensure that this is done tightly.
If the head falls under its own weight, use a 1.5mm tip flathead screwdriver to tightly fasten the cutting head to the machine.
Unlock and swing down the cutter guard. Then rotate the turret so the cutting blade is facing towards you.
To change the cutting blade, undo the blade clamping screw a number of turns to release the blade.
Change or turn over the blade, insert it back into the turret as far as it will go. At this point the position of the blade support plates can be adjusted to suit the thickness of material being cut, and further tightening of the screw will clamp the blade in position.
Rotate the turret back to the cutting position. Replace the guard, ensuring it is locked closed.
Move the head to a comfortable height and lock the respective cutting head’s position using the white nylon locking screw. Ensure that this is done tightly.
If the head falls under its own weight, use a 1.5mm tip flathead screwdriver to tightly fasten the cutting head to the machine.
Unlock and swing down the cutter guard. Then rotate the turret so the scoring blade is facing towards you.
Release the blade clamping screw.
Eject the medium duty utility blade using the black ejector pin, replace the blade to the right of the clamping plate, push the blade in as far as it will go, and tighten the blade clamping screw.
Rotate the turret back to the scoring position. Replace the guard ensuring it is locked closed.
Move the head to a comfortable height and lock the respective cutting head’s position using the white nylon locking screw. Ensure that this is done tightly.
If the head falls under its own weight, use a 1.5mm tip flathead screwdriver to tightly fasten the cutting head to the machine.
Unlock and swing down the cutter guard. Then rotate the turret so the glass wheel is facing towards you.
Pull out the wheel and clip assembly from the holder and replace it with the new wheel and clip assembly.
Rotate the turret back to the glass cutting position. Replace the guard ensuring it is locked closed.
Move the head to the top of the machine (adjacent to the open channel) and lock the respective cutting head’s position using the white nylon locking screw. Ensure that this is done tightly.
If the head falls under its own weight, use a 1.5mm tip flathead screwdriver to tightly fasten the cutting head to the machine.
Hold the twin wheel cutter on to the Cutting Head whilst unscrewing the screw with a 6mm Allen Key.
Slide the twin wheel cutter out through the open channel in the main body and lift it out. Reverse the procedure to fit the replacement twin wheel cutter, ensuring it is properly located flat against the Cutting Head before fastening the screw with the 6mm Allen Key.
