1. Push the reversing valve knob all the way in.
2. Operate the pump handle back and forth until
system working pressure is reached. (This is
indicated by the change in position of all
indicator pins on the metering valves.)
3. Hold this pressure for about a minute to make
sure the grease is distributed.
4. Pull the reversing valve knob all the way out
and repeat steps 2. and 3. This relieves the first
line and pressurizes the second (causing the
indicator pins to move in the opposite direction)
5. Push the reversing valve knob all the way in.
This relieves line pressure.
You have completed the lubrication cycle.
All indicator pins have changed twice and are
now in the original position. The reversing valve
knob is all the way in. The pump is ready for
the next lubrication cycle.

MANUAL PUMPS
General
The DMP Manual Pump is a compact and reliable way of delivering lubricant. Manual pumps are most effective in
applications that require relatively infrequent lubrication and
have a low number of lubrication points. These pumps consist
of a double-acting piston and a quick-fill fitting that allows for
convenient filling of the reservoir.

THE PUMP AND THE LUBRICATED
BEARING.
In a dual line system, lubricant is directed from the pump alternately into one of two supply lines by means of a flow directional
valve, controlled via the directional knob located on the pump.
1. Push the reversing valve knob all the way in.
2. Operate the pump handle back and forth until
system working pressure is reached. (This is
indicated by the change in position of all
indicator pins on the metering valves.)
3. Hold this pressure for about a minute to make
sure the grease is distributed.
4. Pull the reversing valve knob all the way out
and repeat steps 2. and 3. This relieves the first
line and pressurizes the second (causing the
indicator pins to move in the opposite direction)
5. Push the reversing valve knob all the way in.
This relieves line pressure.
You have completed the lubrication cycle.
All indicator pins have changed twice and are
now in the original position. The reversing valve
knob is all the way in. The pump is ready for
the next lubrication cycle.

1.
Push in knob A all the way.
2.
Operate pump handle B back
and forth until the desired pressure
is reached, as indicated on the
pressure gauge C .
3.
Hold the specified pressure for a
minute or two to make sure that
lubricant is being delivered to all
the necessary points.
4.
Pull back the knob A fully and
repeat steps 2 and 3.
5.
Again push in the knob A fully
in order to relive line pressure.

Troubleshooting
1. If the pump handle does not seem to be offering the usual resistance and the pump does not build
up pressure, this is usually a result of air in the reservoir. To remedy, clean out reservoir and
place a small amount of oil in the bottom. Then refill the reservoir with clean grease THROUGH THE
FILL PLUG ONLY.
2. If the pump handle springs back at the end of the discharge stroke or is locked in one position,
this is an indication that the check valves (located on the bottom of the pump) are clogged -- probably as a result of contaminated lubricant. To remedy, clean out the reservoir and check valves (or
replace if you still experience this problem after cleaning). Refill reservoir with clean grease THROUGH
THE FILL PLUG ONLY.
3. If the pump pressure does not rise or the pump pressure rises suddenly, check the piping, measuring valves and any other connected valving for clogs or leaks.
