Dismounting - de Gier GW series Installation Manual

7.2 Maintenance tasks
The motor gearbox has lifetime lubrication. Changing the gear oil is usually unnecessary.
Caution!
For the following tasks it must be ensured that the load cannot start moving by itself after it is
disconnected from the drive.
7.2.1 Checking worm gear wear and shaft play
1. Put the motor gearbox in an unloaded position, for example with the vent closed;
2. Switch off the power;
3. Disconnect the motor gearbox from the drive train, so the output shaft should be able to turn freely;
4. Check the play in the gear unit by turning the output shaft of the drive.
If there is clearly noticeable play, the drive should be dismounted and returned to the manufacturer for inspection.

8 Dismounting

Dismounting may only be carried out by qualified staff (see Section 1.3).
Risk of injury or death! Risk of injury or death due to electrical or mechanical forces!
Before starting to work on the motor gearbox or related parts, always switch the power off at the master
switch or operating switch and lock it out with a padlock to prevent switching on again.
Risk of injury or death! Risk of injury or death due to falling objects!
• Cordon off the hazard area with barrier tape.
• Use a work platform, or lift the motor gearbox using hoisting equipment and appropriate slings fitted
around the output shaft.
