Driver Maintenance

Do not open/remove the gear cover. Opening the gear
cover may alter the factory set bearing pre-load and
may reduce the product life.
Preventative Maintenance Schedule
The operating conditions of your particular system
determine how often maintenance is required. Establish
a preventative maintenance schedule by recording when
and what kind of maintenance is needed, and then
determine a regular schedule for checking your system.
