LUBRICATING THE SLEW DRIVE
IMPORTANT
REGULARLY LUBRICATE THE SLEW DRIVES TO
PROLONG THEIR SERVICE LIFE AND ENSURE SAFE
OPERATION.
IMPORTANT
ALWAYS USE THE LUBRICANTS SPECIFIED IN THE
ORDER DRAWING. IF USING OTHER LUBRICANTS
PAY ATTENTION TO THE RELATIVE MIX ABILITY
OF THE SUBSTANCES. THE STANDARD LUBRICANTS
USED ARE "R.TECC NORPLEX LKP2" FROM RHENUS,
OR THE GREASE "OPTIMOL LONGTIME PD0" FROM
CASTROL. IF IN DOUBT, OR IF THERE IS NO SPECIFI-
CATION ON THE DRAWING, CONSULT WITH OUR
CUSTOMER SERVICE. USING THE WRONG LUBRI-
CANT MAY CAUSE DAMAGE TO THE SLEW DRIVES
AND REDUCE THE SERVICE LIFE. IN THIS CASE, ANY
WARRANTY SHALL BE EXCLUDED. COMPLY WITH
THE INSTRUCTIONS PROVIDED BY THE LUBRICANT
MANUFACTURER!
If possible use a central lubrication system to lubricate the
raceway system. In this regard ensure that the hoses are
filled with grease at commissioning and that the storage
tanks are regularly topped up with grease.
An automatic re-lubricating system significantly facil-
itates re- lubrication for the raceway system and the
toothing. Functional safety as well as wear behavior
are improved.
Comply with the instructions in the operating manual
provided by the respective manufacturer for lubrica-
tion of optional intermediate gear units, brakes, and
motors.
If it is evident that moisture has penetrated into the
slew drive, or has been absorbed by the grease, you
must re-lubricate more intensively.

1. Fresh lubricant
2. Lubricating nipple, bearing ring
3. Lubricating ring housing
4. In succession, press grease into all lubricating nip-
ples while simultaneously turning the slew drive all
the way through, until a continuous collar of grease
forms under at least one seal.
5. Ensure that old lubricant can escape without
obstruction.
