5.6 Replace carriage lid
After dismantelling the carriage lid, the frontal stop surface of the carriage is
sharp-edged. If handled carelessly during maintenance, you might cut yourself.
Protection gloves must be worn!
Carriage lids must be exchanged if:

the recommended exchange interval of the lip seal is reached (see Table 11).

abnormal or one-sided wear is present on the lip seal (Figure 16, Pos 1), due to
improper operation or environmental influences or incorrect installation
(misalignment) of the steel belt cover or carriage cover.


or after a collision with adjacent machine parts, provided that important functional
parts of the linear axis have not been damaged (guide, carriage, toothed belt,
deflection stations). In this case, the complete axis must be exchanged.
Exchange process of carriage lid
To exchange the carriage lid, it is not necessary to loosen the steel strip cover.

Loosen the screws of the cover lid (see Figure 13, Pos. 4) and dispose the old lid
(see Figure 13, Pos. 3).

Position the new carriage lid on the carriage plate and screw it to the required
tightening torque see Table 13).
Take care that the carriage lid is aligned exactly to the carriage profile (lip seal
parallel to the steel strip cover). If the lip seal is mounted at an angle, there is a
risk of premature wear.

Check if the steel strip cover is touching the carriage. Therefore move the
carriage over the entire length of the stroke and pay attention to grinding noises.

In the stroke area slightly moisten the steel strip with Teflon spray.
