Step 3

Remove the belt tensioner screw. During

loosening hold the lower part in your hand to

prevent it from falling down on the Y axis.

Loosen the four screws on both belt holdings as

far as the belt can be pulled out.

Now it is possible to remove the whole belt by

pulling on t

he upper end.

Step 4

Remove the deflection pulley by removing the

four screws at the back of the Z axis.

Step 5

Check the length of the new belt which must be

4453 mm ± 2 mm

Push the belt over the upper pulley and down

inside the back of the Z axis until it does not go

furthe

Step 6

For the next step it is required to have access to

the bottom pulley. Therefore, the whole Y axis

must be lifted and secured. Put a piece of wood

or steel below the axis to hold it securely into

place. Do not put force on the gripper itself.

Instead, secur

e the spacer below the Y axis.

Another possibility is to fasten a clamping set

around the Z axis. Be careful not to damage or

scratch the linear bearings.

Note:

The spacer has to be securely placed as

work will be done right below the Y axis.

If the Y ax

is falls down it could cause

injury and damage to the machine. In

case of doubt, only lift the axis for a short

distance.

For this step it

is helpful to ask a further person

for assistance.

The assisting person must push down the belt at

the gap where the deflection pulley was located,

while the bottom pulley can be turned to hook

the belt.

Pull the belt out for around one meter.

Securely hold the Y axis and remove the spacer.

Lead the belt through the space behind the Y

axis and lay the axis carefully down.
