-Checking/cleaning of bearings-
- Anti-friction bearings must be checked and cleaned from
time to time with the inspection intervals being governed
by the operating conditions. If it
’
s possible to monitor
condition of the bearings during the operation by listening
to running noise, measuring the bearing temperature or
checking the lubricant, it is generally sufficient to
thoroughly check and clean the bearings (races, cages and
rolling elements) and all other parts of the mounting in the
course of general machine inspection or repair. However,
more frequent checks are needed if bearings are subjected to heavy loading.
- After cleaning every component
with suitable cleaning agent, bearings must be thoroughly dried and then immediately
protected against corrosion by oiling or greasing them. This part is especially important for
the machine that remains shut down for a lengthy period of time.
-Screwed and electrical connections-
- After 20-30 hours screws and bolts have to be checked whether they are tight or not.
- Self-locking nuts are to be used only once.
- The machine components have to withstand high loads and stress during production due to
mechanical forces and vibrations. Especially the tight fit of the screwed connections on safety
related components must be checked regularly.
- Check regularly the tight fit of the electrical connections.
ATTENTION!
After 20 - 30 working hours
screws and bolts have to be
checked wether they are tight or
not!
Read this manual carefully!
