4.1 Check the oil level
The installation must comply with the configuration on the rating 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.
The oil level does not need to be checked on gear units without oil level screw (see 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 must 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:
 Standard configuration M4 (V1 and V5) helical gear units have an angled pipe for checking
the oil level. This must point vertically upwards as shown in Figure 4-1 C. Before checking the
oil level, the pressure vent must be unscrewed.
 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 A, C. 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. The dipstick
then just dips into the oil.
 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 rating 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 6.3 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 6.3 for torque values)
3. Gear units with an oil level vessel:
 The oil level must be checked in the oil level vessel with the aid of the dipstick plug (thread
G1 1/4). The oil level must be between the upper and lower marking when the dipstick is fully
screwed in (see Figure 4-1 B). These gearboxes may only be operated in the configuration
stated in Section 6.1.
Danger!
Before commissioning, the oil level must be checked with the supplied dipstick.
