Change the oil in the vibrator gearbox. Remove the Drain Plug from the bottom of the
gearbox and the Breather/Filler Plug from the top. Allow the oil to drain out
completely into a suitable container – this is best done at the end of a shift when the oil
is relatively warm and thin. Replace the Drain plug and fill with new clean oil through
the Breather/Filler hole until the oil level in the gearbox is approximately half way up
the sight glass – this is approximately 4 litres (1.05 US gallons).
Re-fit the Breather/Filler Plug using a new seal and tighten.
The old oil must be taken to a certified waste disposal centre or handed over to a
certified waste disposal contractor.
Generally any good quality mineral based gear oil in the class API GL-5 with viscosity
class SAE 75W/90 will be suitable. Alternatively, in hotter climates fully synthetic oil
of the same classification may be used. For example:

It is recommended that the unit be inspected and serviced by the manufacturer. Apart
from undertaking to do the relevant preventative maintenance work and checks as
described above Dawson will inspect the structural integrity of the equipment and
ensure there are no safety related matters that may go unchecked. Bearings and gears
will also be inspected to check for signs of unusual wear or potential problems. In
some countries it is a requirement by law that the unit be inspected by qualified
personnel.
