ATTENTION:
This equipment generates very high fluid pressure. High pressure spray can cause serious
injury. Read and understand all instructions before operating.
Never point the spray gun at anyone or at any part of the body. Never put hand, fingers over the
spray tip.
Always have the tip guard in place on the spray gun while spraying.
High pressure fluid in the hoses can be very dangerous. If the hose develops a leak, split or
rupture due to any kind of wear, damage or misuse, the high-pressure spray emitted from it can
cause a fluid injection injury or other serious bodily injury or properly damage.
Never use a damaged hose
Tighten all fluid connections securely before each use. High pressure fluid can dislodge a loose
coupling or allow high pressure spray to be emitted from the coupling.
Proper hose grounding continuity is essential to maintaining a grounded spray system.
If any fluid appears to penetrate your skin, get emergency medical care at once. Do not treat as
a simple cut. Tell the doctor exactly what fluid was injected.
All chemicals used in the pump must be compatible with the wetted parts of the pump.
PRESSURE HAZARD
This pump can develop 240 bar working pressure. Be sure that all spray equipment and
accessories used are rated to withstand this pressure. Do not exceed the maximum working
pressure of any component or accessory used in the system.
FIRE OR EXPLOSION HAZARD
Static electricity is created by the flow of fluid through the pump and hose. If every part of the
spray equipment is not properly grounded, sparking may occur and the system may become
hazardous. Sparking may also occur when plugging in or unplugging a power supply cord.
Sparks can ignite fumes from solvents and the fluid being sprayed, dust particles, whether you
are spraying indoors or outdoors, and can cause a fire or explosion.
If you experience any static sparking or even a slight shock while using the equipment, stop
spraying immediately. Check the system for proper grounding. Do not use the system again until
the problem has been identified and corrected.
GAS ENGINE (WHERE APPLICABLE)
Always place pump outside of structure in fresh air. Keep all solvents away from the engine
exhaust. Never fill fuel tank with a running or hot engine. Hot surface can ignite spilled fuel.
Always attach ground wire from pump unit to a grounded object, such as a metal water pipe.
Refer to engine owner’s manual for complete safety information.
PRESSURE RELIEVE PROCEDURE
To reduce the risk of serious bodily injury, including fluid injection, splashing fluid or solvent in
the eyes or on the skin, or injury from moving parts or electric shock, always follow this
procedure whenever you shut off the sprayer, when checking or servicing any part of the spray
system, when installing, cleaning or changing spray tips, and whenever you stop spraying:

GROUNDING INSTRUCTIONS
Electric models must be grounded. In the event of an electrical short circuit, grounding reduces
the risk of electric shock by providing an escape wire for the electric current. This product is
equipped with a cord having a grounding wire with an appropriate grounding plug. The plug
must be plugged into an outlet that is properly installed and grounded in accordance with all
local codes and ordinances.
DANGER! - Improper installation of the grounding plug can result in a risk of electric
shock. If repair or replacement of the cord or plug is necessary, do not connect the green
grounding wire to either flat blade terminal. The wire with insulation having a green outer
surface with or without yellow stripes is the grounding wire and must be connected to
the grounding pin.
NB: Before starting to work the pump must be connected to ground. The pump must be
connected to ground with a ground wire which is supplied with the pump (4mm2 of
section and a clamp).

DAILY MAINTENANCE
Two daily procedures are required for routine operator maintenance on this unit:
•Lubricating the upper packing.
•Cleaning the rock catcher.
Lubricating the Upper Packings
•Clean out the paint that has seeped past the upper packings into the packing oil
reservoir above the fluid section.
•Fill the packing oil reservoir 1/2 full with Piston Lube supplied by the factory. This will
extend packing life.
NB: Do not over -fill the reservoir so that it overflows and drips into the paint.
MAINTAINING THE HYDRAULIC SYSTEM
CAUTION! Use of Hydraulic Fluid DIN 51524 standard, section 1 & 2 (for
example ISO VG 46) is mandatory in the hydraulic system. Do not use any
other hydraulic fluid. Use of any other hydraulic fluid may seriously
damage the hydraulic system and will void the warranty.
1. Check the hydraulic fluid daily. It should be at the “Full” mark on the dipstick. If it is low,
add only Hydraulic Fluid DIN 51524 standard, section 1 & 2 (for example ISO VG 46).
Never add or change hydraulic fluid except in a clean, dust-free area. Contamination of
the hydraulic fluid will shorten hydraulic pump life and may void warranty.
2. Change the hydraulic fluid every twelve months. Drain the old fluid from the tank. Start
the unit at just enough pressure to operate the fluid section. Run the unit at this low
pressure for at least 5 minutes. This removes air from the system. Check the fluid level
after this procedure.
3. The hydraulic system has an external, replaceable hydraulic filter. Change the filter
every twelve months.

upstroke only or
goes up slowly and
down fast.
▪Lower foot valve ball is not
seating due to trash or wear.
▪Material too viscous to siphon.
▪Air leaking in on siphon side or
damaged siphon hose. Siphon
may be too small for heavy
material.
▪Remove foot valve assembly.
Clean and inspect. Test foot
valve by filling with water; if ball
fails to seal the seat, replace
ball.
▪Thin material, contact
manufacturer for proper thinning
procedures.
▪Tighten all connections between
pump and paint container. If
damaged, replace. Switch to
larger diameter siphon set.
Pump delivers on
down stroke only or
goes up fast and
down slowly.
▪Upper ball is not seating due to
trash or wear.
▪Lower packing set is worn.
▪Check upper seat and ball with
water. If ball fails to seal,
replace seat.
▪Replace packing set if worn.
Pump moves up
and down fast,
delivering material.
▪Material container is empty or
material is too thick to flow
through siphon hose.
▪Bottom ball stuck to foot valve
seat.
▪Siphon hose is kinked or loose.
▪Refill with new material. If too
thick, remove siphon hose,
immerse fluid section in
material, and start pump to
prime. Add thinner to material.
Change to bigger siphon set.
Open bleed valve to remove air
and restart pump.
▪Remove foot valve. Clean ball
and seat.
▪Straighten.
Pump moves up
and down slowly
when spray gun is
shut off.
▪Loose connections. Bleed valve
is open partially or bleed valve
is worn. Lower packing seat is
worn.
▪Upper and/or lower ball not
seating.
▪Check all connections between
pump and gun. Tighten as
necessary. If material is flowing
from bleed hose, close bleed
valve or replace, if necessary.
Should none of the above be
evident, replace lower packing.
▪Reseat balls by cleaning.
Not enough fluid
pressure at gun.
▪Spray tip is worn.
▪Outlet filter or gun filter is
clogged.
▪Low voltage and/or inadequate
amperage.
▪Hose size or length is too small
or too long.
▪Replace.
▪Clean or replace filter.
▪Check electrical service.
Correct as required.
▪Increase hose size to minimize
pressure drop through hose
and/or reduce hose length.
Pump chatters on
up or down stroke.
▪Solvent has caused upper
packing to swell.
▪Replace packing.

TROUBLE
POSSIBLE CAUSE
SOLUTION
Oil motor stalls at
bottom (no unusual
heat problems).
▪Fluid pump piston seat
unthreaded.
▪Valve sticking or oil motor trip
rod shifter assembly separated.
▪If connecting rod is okay,
remove cylinder head plug and
pop valve down. Replace plug
and start machine. If machine
cycles up and stops at bottom
again, then problem is piston
seat on fluid pump. Check
piston seat. Repair or replace
as necessary. If piston seat is
okay and problem does not
change, check oil motor.
▪Remove valve and check for
scratches and rough movement
when sliding it up and down.
Replace valve and spool in this
condition. Check trip rod for
possible separation and spool in
this condition. Check trip rod for
possible separation.
Oil motor stalls at
top (no unusual
heat problems).
▪Valve sticking.
▪Broken spring retainer (valve
rod assembly).
▪Broken spring or valve rod.
▪Air in hydraulic motor.
▪Air in fluid pump
▪Remove valve and check for
scratches and rough movement
when sliding it up and down.
Replace valve and spool in this
condition.
▪Replace valve rod assembly.
▪Replace valve rod assembly
▪Reset valve. Purge Air,
generally accomplished by low
pressure cycling of motor/pump
assembly for 5-10 minutes.
Check for causes of air
introduction:
oLoose fittings in tank.
oLoose fittings on hydraulic
pump.
oLoose hose connections.
oLow oil in reservoir.
▪Stall at top can occur randomly
when fluid pump picks up air.
Reset valve. Avoid air in the
fluid pump.
