4 Repair steps
Where possible, it is recommended to remove the planar surface gantry from the system entirely before carrying out the
repair.
Before starting the repair, dismantle any attachments in accordance with the instructions in the accompanying operating
instructions.
Keep your working environment clean and tidy.
Before dismantling the planar surface gantry, it is imperative that the cause of the failure is investigated to prevent
repeated and premature failure. A planar surface gantry that has been used as intended will not normally exhibit any
premature signs of failure.
This investigation is not necessary in the case of non-premature failure (fatigue time). However, the condition of the
toothed belt (general status, toothed belt pretensioning, etc.) should always be checked also.
In case of uncertainty, we recommend replacing all the components mentioned to rule out reciprocal effects during later
operation.
If the planar surface gantry suffers premature failure, the operating conditions should be observed more closely.
The following possibilities should be considered, among other things:
– Overloading
• In case of overloading, the application parameters (load, speed) should be adjusted accordingly.
– Ambient conditions/material resistance
• Check whether the ambient temperature is within the permissible range.
•
Check the chemical and physical ambient conditions for hazardous substances, such as dust, abrasive particles,
cooling lubricants, solvents, ozone, radiation, water-soluble substances, greases and oils, etc.
Note
The repair should preferably be carried out on a stable and flat work surface with storage for small parts.
To prevent damage to sealing rims and toothed belt, do not use pointed or sharp-edged assembly aids.
The planar surface gantries can be divided into two groups for the repair, which differ from one another in the repair steps.

4.1.1 Preparatory steps
Danger
Risk of fatal injury from electric shock.
– The control system of the planar surface gantry remains charged after the voltage has been switched off (capacitor
voltage). As such, you must wait approx. 3 minutes after switching off the voltage before the motor cables can be
removed. The capacitors discharge their voltage during this time.
4.1.1.1 Dismantling covers
When dismantling the covers, pay attention to the position of the Festo logo. To ensure the orientation defi -
nition is clearly retained, the covers must be remounted on the same side during the subsequent assembly
(
