Safety notes
NOTICE
Regreasing intervals for rolling-contact bearings
The regreasing intervals for rolling-contact bearings are different than the inspection
intervals. If the rolling-contact bearing is not regreased adequately it can be damaged.
Comply with the regreasing intervals for rolling-contact bearings, the regreasing intervals
are specified on the lubricant plate.
When inspecting a motor, it is generally not necessary to dismantle it. The motor only has to
be dismantled if the bearings are to be replaced.

dry compressed air.
NOTICE
Cleaning intervals depend on the degree of fouling
The frequency of the cleaning intervals depends on the local degree of fouling. The
machine can overheat if the cooling air passages are fouled and the cooling air cannot
flow without obstruction.
Check for fouling regularly and clean the cooling air passages through which the
ambient air flows.
WARNING
Personal protective measures when working with compressed air
When cleaning with compressed air, dust, metal chips, or cleaning agents can be
whirled up. Injuries can result.
When cleaning using compressed air, make sure you use suitable extraction equipment
