Filling With Lubricant - Siemens FLENDER H SH Series Assembly And Operating Instructions Manual

7.1.2

Filling with lubricant

• In the case of gear units equipped with auxiliary drive, loosen oil drain plug on intermediate flange
between auxiliary and main gear units and drain off the residual oil into a collecting vessel. Clean oil
drain plug thoroughly and screw in place.
• Undo and remove fastening screws on the inspection and/or assembly cover.
• Remove cover with seal from housing (seal will be used again).
Using a filter (max. mesh 25 μm), fill the gear unit with fresh oil up to the MAX mark on
the oil dipstick or the middle of the oil­sight glass.
Remember to fill the oil pockets above the bearings and (with bevel­gear units) at the
input shaft on the inside.
• In the case of gear units with add­on backstop, release the screw plug on the backstop cover and pour
in approx. 0.5 l fresh oil of the total oil quantity via a filter (max. filter mesh 25 μm).
• Screw in the screw plug.
The sealing surfaces must not be contaminated nor damaged.
The quality of the oil used must meet the requirements of the separately supplied BA 7300
operating instructions, otherwise the guarantee given by Siemens will lapse. We urgently
recommend using one of the oils listed in BA 7300, because they have been tested and meet
the requirements.
Information on the type, quantity and viscosity of the oil is given on the rating plate on the gear
unit.
The oil quantity shown on the rating plate is to be understood as an approximate quantity. The
marks on the dipstick or oil­sight glass are decisive for the amount of oil to be filled in.
In the case of gear units fitted with forced lubrication or an oil­cooling system, the oil circuit must
also be charged with oil. To do this, briefly start up the gear unit with add­on pump (observing
the description in section 8).
• Check the oil level in the gear­unit housing with the oil dipstick or by means of the oil­sight glass.
The oil level must be at the upper mark on the oil dipstick or the middle of the oil­sight glass.
Remove any oil spillage immediately with an oil­binding agent.
• Place inspection or assembly cover including seal on the housing.
• Place the fastening bolts of the cover and tighten them to the specified torque (see item 10.2.13).
