Plunger Pumps
Installation (Continued)
NOTE: The fittings used must be rated
for the pressure of the unit.
Step 5: Start pump, watch pressure
gauge and turn (See figure
6 ref. no. 2) using 3mm hex
clockwise until recommended/
rated pressure is obtained. Line
pressure will be approximately
200 psi less then actual head
pressure. DO NOT set line
pressure to rated.
Step 6: Release trigger and make sure
there is minimal spike (200-300
psi) (Repeat this step two or
three times).
Step 7: Tighten nut (See figure 4 ref.
no. 3) down against (See figure
6 ref. no. 4).
Step 8: Replace black cap (See figure 6
ref. no. 46)
NOTE: Now pressure can be decreased
by turning black knob counterclockwise,
but the pressure cannot be increased
to a rating higher than was set. We
recommend this procedure be done by
a qualified high pressure pump service
technician. Failure to properly adjust
can cause serious damage to equipment
and body.
Failure to use a pressure gauge
may cause the pump to be set
at a pressure that exceeds its
specifications. Resulting in injury
or pump damage.
