4. Commissioning
4.1 Check the oil level
Danger!
The oil level must be checked prior to commissioning.
The installation must comply with the configuration on the name plate. Section 6.1 describes the
versions and the corresponding oil level screws. With double gear units, the oil level must be
checked on both units. The pressure vent must be at the position marked in Section 6.1.
Gear unit types that are not supplied full of oil must be filled before the oil level is checked. (See
Section 5.2)
Checking the oil level:
1. The oil level may only be checked when the gear unit is at a standstill and has cooled
down. The gear unit must be secured to prevent accidental switch-on.
2. Gear units with oil level screw:
 The oil level screw corresponding to the version must be screwed out. (See Section 6.1)
 The oil level in the gear unit should be checked with the supplied dipstick (Part No.:283 0050)
as shown in Figure 4-1. To do this, the part of the dipstick which is submerged in the oil must
be held vertically.
 The maximum oil level is the lower edge of the oil level hole.
 The minimum oil level is approx. 4 mm below the lower edge of the oil level hole.
 If the oil level is not correct, it must be adjusted by draining off oil or topping up with the type
of oil stated on the name plate.
 If the screw lock coating in the thread of the oil drain screw or oil level screw is damaged, a
new oil level screw must be used or the thread cleaned and coated with securing adhesive,
e.g. Loctite 242, Loxeal 54-03 prior to insertion.
 Check the sealing ring for damage. Replace with a new sealing ring in case of damage.
 Fit the oil level screw together with the sealing ring and tighten to the correct torque. (See
Section 6.4 for torque values).
 If the pressure vent has been unscrewed, reinsert it together with the sealing ring and tighten
to the correct torque. (See Section 6.4 for torque values).
3. Gear units with oil inspection glass:
 The oil level can be seen directly in the window
 The correct oil level is the middle of the inspection glass
 If the oil level is not correct, it must be adjusted by draining off oil or topping up with the type
of oil stated on the name plate.
4. All previously removed screws must be screwed back in correctly.
