ANNEX 1 - CHECKING THE OIL LEVEL ON ATEX-SPECIFIED GEAR UNITS
Gear units are normally fitted with oil level check plugs.
To check the oil level, first identify the level plug.
- Horizontal position:
Remove the plug and insert a bar of the right size in the hole and of the shape shown in the fi-
gure.
- Vertical position:
Use a rod to check that the oil level is between the MIN and MAX marks, then screw the plug
back in.
If the level is more than 3 mm below the spill level, top up and check the reason for the drop in oil
level.
Gear units conforming to Directive 94/9/EC and designed for a vertical mounting position, are
normally equipped with an oil expansion chamber fitted with service plugs for filling, checking the
oil level and venting internal overpressure.
N.B.: MAKE SURE THE ROD IS
POSITIONED FLAT AGAINST THE
EDGE OF THE THREADED HOLE
