Fluids under high pressure can
penetrate the human skin and can cause
severe injury, possibly resulting in
amputation or death.
Hot liquids and chemicals can also
cause burns or injury.
DO NOT at any time place hand or
any other part of the body in front of
spray stream.
If any part of the body comes in
contact with the spray stream,
immediately consult a physician.

WARNING
It is normal for the Suction Dampener to move
when fluid is being pumped. A tear or rupture in
the Dampener can cause a suction leak. The
Pump will not operate properly in this condition.
Replace the Dampener if Dampener is ruptured.
DIAPHRAGM:
If fluid is seen coming out of the Weep Hole at the
bottom of the Pump, a Diaghragm has ruptured
and must be replaced.
Remove the Diaphragm cover after having
dismantled the valve compartment as indicated in
FIG. 3. The diaphragm may then be changed. If
fluids have reached the crankcase it is strongly
recommended to lubricate the entire pump with
ample amount of grease.
PUMP LUBRICATION:
Once or twice during the season, depending on
how often the sprayer is used, it is recommended
to lubricate the pump with 2-3 pumps from a grease
gun of a high quality multipurpose grease. (See
FIG. 4)
VALVES:
Dismantle valve compartment. Before changing
the valves, note the orientation of the valves so
that they may be replaced correctly. It is
recommended to use new gaskets when changing
or checking valves, and tighten bolts securely.
