Lubrication - WORKMASTER GO-A8-PW Operator's Manual

A heavy-duty Lubricator is permanently installed on the air line between the
Throttle Valve and the Impactor. The Lubricator has two reservoirs. The upper
chamber holds the oil while the lower chamber acts as a passageway for the air
to enter and to exit the Lubricator. An adjustment valve between the two
chambers allows air to enter the upper chamber pressurizing the chamber until
the entire Lubricator is at equilibrium. When the GO-A8-PW is operated, air is
drawn from the Lubricator. This flow of air drops the pressure in the lower
chamber below the pressure in the upper chamber. The difference in pressure
allows oil to be pushed into the lower chamber and then out to the Impactor.
When the GO-A8-PW's throttle is released, the upper chamber is re-
pressurized. When the throttle is engaged the lower chamber is pressurized and
the cycle continues.
1. To fill the Lubricator, simply remove the Fill Plug, See Figure 5,
and pour 16 oz (1 pint) of the high grade air tool lubricant
provided. It is not necessary to disconnect the airline to the GO-
A8-PW while filling.
IMPORTANT
VII. LUBRICATION
The Lubricator on the GO-A8-PW is empty when
shipped from the factory. To avoid damage to
the Impactor the Lubricator must be filled prior to
operation.
WORKMASTER's TOOL-LUBE Air Tool Oil is
recommended. It is a High-Grade Air Tool Oil with
absorbing emulsifiers. Do Not Use any of the
following: Kerosene, hydraulic fluid, transmission
fluid, spindle oil, motor oil or antifreeze.
