1 - INSTALLATION
RECOMMENDATIONS
Installation must be performed by qualied personnel.
Allow sucient room around the geared motor for plugs (or
vessel) accessibility:
- 200 mm: G1/4’’ plug for Cb 30 to 35.
- 500 mm: G3/4’’ dipstick for Cb 36 to 38.
H
1/4 H min.
Gearbox:
For the installation of Compabloc 3000 gearbox, follow the
“Recommendations” chapter in the general manual.
If the gearbox is tted with a MU universal mounting with a sti
coupling by key, we recommend the application of a lithium
paste (molykote TP42 or equal) on the motor shaft.
Motor:
For connection of the complete drive system (with brake),
follow the instructions of corresponding maintenance delivered
with the goods in the parcel.

2 - MAINTENANCE
Control after commissioning (50 hours of operation).
Check tightening of fastening screws and belt tensioning if
applicable.
Preventive maintenance visit.
- Check regularly that the recommendations concerning
mechanical and electrical installation are still complied with.
- If the gearbox is tted with a breather plug, make sure that the
vent hole of the plug is not obstructed.
- Inspect the seals.
- Clean the ventilation louvres of the motor.
- Lubricate the bearings of the motors tted with grease
nipples.
- Control the air gap of brake motors.
Oil, seals, bearings.

commissioning.
2 to 5 years
Dismantle AP. Clean
it. Replace the grease
completely.
3 - LUBRICATION
For operation in ambiant temperature between -10°C and
+40°C, Compabloc Cb 3000 reducer is shipped, as standard,
with mineral Extreme Pressure oil: EP ISO VG 220.
From -30°C to +60°C: synthetic oil PAO ISO VG 150.
From -30°C to -10°C : synthetic oil PAO ISO VG 32.
From -30°C to +60°C and for use in the food industry: synthetic
oil PAO H1 ISO VG 150.
You must use an oil of the recommended type.
Polyglycols lubricants cannot be mixed with mineral or
synthetic lubricants of a dierent type.
Oil capacities.
The oil capacities shown in table (see § 3.1, 3.2, 3.3) are
approximative: values and should be used only as reference
in determining how much oil to provide. The proper oil levels
can only be determined by:
- Cb 31 to 35: plug: lling the reducer to the level of the plug
(Cb 30 excepted);
- Cb 36 to 38: dipstick: adjust oil level between the 2 marks
(up/down).
