3 - LUBRICATION

For operation in ambient temperature between -10°C and
+40°C, Orthobloc 3000 reducer is shipped, as standard, with
mineral Extreme Pressure oil : MIN 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.
Polyglycol lubricants cannot be mixed with mineral or synthetic
lubricants of a different type.
Oil capacities.
The oil capacities shown in table (see § 3.2 to § 3.4) 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:
- Ot 31 to Ot 35: plug: filling the reducer to the level of the
plug,
- Ot 36 to Ot 39: dipstick (J): adjust oil level between the 2
marks (up/down).
