Preparing Lubricant Pumps For Operation.

TM 5-4930-233-14

TM 4930-14/1

Start engine (paragraph 2-5 a) and allow pressure to build to 140-175 psi.

Turn the handles of the air pressure regulators (12) clockwise, until set at the desired air pressure (100 psi),

as registered on the air pressure gages (13).

Air pressure to each pump must be adjusted at the individual pump. Turn the handle of the air pressure

regulator (12) clockwise to increase air pressure, and counterclockwise to decrease air pressure. The exact

air pressure to operate pumps must be based on delivery rate required and viscosity.

Open the circulating valve (14) of each pump by turning the valve handle two full turns counterclockwise.

After charging pump with lubricant, close each circulating valve (14) by turning it all the way clockwise.

WARNING

Always wear safety glasses while operating lubrication and

servicing unit. Failure to do so can lead to severe personal injury.
