DUST- & DRIP-PROOF TYPE SPECIFICATIONS MANUAL

5. Maintenance

The basic structure of the dust- and drip proof type robot is the same as that of the

standard robot. For the contents of inspection, etc., see the TH850A/TH1050A

Maintenance Manual provided separately.

This section deals with the layout of the robot mechanical components and the

procedures for replacing the bellows (upper and lower sides) and for mounting and

dismounting the covers.

5.1

Layout of Robot Components

The layout of the robot mechanical components is shown in Fig. 5.1. (The figure

below shows the TH850A robot.)
