Pump
Lubrication:
To lubricate pump, use 10W-40 non-
detergent oil for pump crankcase. Crankcase must be
filled to center of sight glass window found on the rear of
the pump.
During the break-in-period, make sure the oil
is changed after the first 25 hours of operation. After that,
replace oil every 3 months or 300 hours of operation,
whichever comes first.
Proper Pump Care:
•
DO NOT
pump acids.
•
DO NOT
allow pump to run dry.
•
Winterize if storing in freezing temperatures,
refer to
Storage
for details.
•
Use a water softener on the water system if
known to be high in mineral content.
•
Use only high quality detergents and follow man-
ufacturer’s mix recommendations.
•
Flush the system with clear water immediately
after using detergent solutions.
•
Clean filter screen on detergent inlet line periodi-
cally.
•
Flush the pressure washer system with anti-
freeze if storing for an extended period of time,
refer to
Storage
to details.
Pump Motor
Inspect the pump motor at regular intervals. The exterior
of the motor should be kept free of dirt, oil, grease, water,
etc. Keep all ventilation openings free from debris. If the
motor is equipped with grease fittings, lubricate the
motor after every 1000 hours of operation with Chevron
SRI #2 lubricant or equivalent. If the motor is not
equipped with grease fittings, the pump motor bearings
are permanently lubricated and will not require any addi-
tional lubrication.

Heating Coil
Coil Descaling:
In hard water areas, scale buildup
within the heating coil will occur. Scale deposits will
decrease the water temperature rise and may eventu-
ally clog the heating coil. Contact your local service
center when descaling is needed.
Coil Desooting:
Poor grades of fuel oil or inadequate
combustion air will cause heavy soot buildup on the
outside surface of the heating coil. These deposits will
insulate the coil. This will restrict the air flow through
the coil, further aggravating the soot buildup. Contact
your local service center when desooting is needed.
