7.9 Checking for grease/oil leakage
WARNING
Loss of the brake function!
The elevator car can move in an uncontrolled manner through the shaft.
Make sure the brake drum and other components of the brake are free of
grease and oil.
Rectify the cause of grease/oil leakage.
Run the brake test.
Replace the contaminated brake.
NOTICE
Danger when using commercially available brake cleaning agents!
Damage to the brake
For cleaning work on the brake, only use the cleaning agent isopropanol
(isopropyl alcohol). Observe the information provided by the brake man-
ufacturer Appendix.
Degree of contamination Procedure
If a small amount of oil/grease
leakage is determined
Clean and check regularly within the
framework of maintenance
Every 3 months
(and/or every 6 months in the case
of low frequency of use: fewer than
50,000 runs per year)
If a large amount of oil/grease
leakage is determined or brake
disc/brake linings are already
fouled with oil/grease
Clean the machine and, if necessary,
the brake, and repair as quickly as
possible.
Before continuing operation until
modification, run a brake test. If the
braking effect is inadequate: Shut
down installation.
If necessary, check on a daily basis
whether oil/grease is still leaking. If
this is the case: Shut down installa-
tion.
Repair after 4 weeks at the latest
