Maintenance Plan

Overview

The maintenance intervals may have to be adapted to the greatly varying service lives depending on the application.

For procedures to replace the different parts, refer to Replacing Parts.

Maintenance Schedule

Perform the following maintenance tasks only once:

Date	Action
Two months after the date of manufacturing (DOM)	oVerify the axis by visual inspection for any damage or missing parts. Especially moving parts and parts at risk for collisions such as carriage, contact plate, toothed belt, toothed belt tensioner, ball bearing of the toothed belt pulley, cover strip, cover strip clamp or mounting elements. oVerify the tension of toothed belt and adjust it, if necessary.

Date

Action

Two months after the date of manufacturing (DOM)

oVerify the axis by visual inspection for any damage or missing parts. Especially moving parts and parts at risk for collisions such as carriage, contact plate, toothed belt, toothed belt tensioner, ball bearing of the toothed belt pulley, cover strip, cover strip clamp or mounting elements.

oVerify the tension of toothed belt and adjust it, if necessary.

Perform the following maintenance tasks within the stated intervals:

Interval	Action
Every 400 hours of operation or every month	oClean the axis, if necessary. oLubricate the guide system, if necessary.
Every 1,000 hours of operation or every three months	For PAS4•BR / PAS4•HR: oClean the axis. oLubricate the roller guide
Every 2,000 hours of operation or every six months	oClean the axis. oVerify the toothed belt abrasion and replace it, if necessary. oVerify the tension of toothed belt and adjust it, if necessary. oVerify the axis by visual inspection for any damage or missing parts. Especially moving parts and parts at risk for collisions such as carriage, contact plate, toothed belt, toothed belt tensioner, ball bearing of the toothed belt pulley, cover strip, cover strip clamp or mounting elements. oVerify the sensors for functionality. oVerify the guide system for unusual noises. If unusual noises occur, refer to Troubleshooting. oVerify all parts for bolted connections. oFor PAS4•BB / PAS4•HB: lubricate the recirculating ball bearing guide oFor PAS4•BR / PAS4•HR: lubricate the roller guide
Annually or after an uncontrolled stop (stop category 0)	oVerify the brake function during operations. For further information, refer to the corresponding motor manual of the optionally pre-installed Schneider Electric motor.
Every 20,000 hours of operation	oReplace the optionally pre-installed Schneider Electric motor.
Every 30,000 hours of operation	oReplace the optionally pre-installed Schneider Electric gearbox.
Every four years after the date of manufacturing (DOM)	oReplace the toothed belt as a precautionary measure. oSuggestion: Replace the toothed belt pulleys when replacing the toothed belt.

NOTE: The gearbox (optional equipment) and the ball bearings are lubricated for life.
