7.16 Maintenance and repair
Inform operating personnel before starting maintenance and repair work. Protect all
plant parts and operating media connected before and after the machine, such as
compressed air and hydraulics, against unintentional start-up. In all maintenance,
inspection and repair work, switch the machine off and secure the main switch
against unintentional start-up.
Secure larger assemblies carefully to lifting gear. Check loosened screw connections
for firm seating. Use only original spare parts.
After maintenance work is finished, check the safety devices for
function.
