Pump
Lubrication: To lubricate pump, use 30W non-detergent
oil for pump crankcase. Crankcase must be filled to center
of red dot on oil gauge found on the side of the pump,
refer to Figure 10. During the break-in-period, make sure
the oil is changed after the first 40 hours of operation.
After that, replace oil every 3 months or 500 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 manu-
facturer's mix recommendations.
• Flush the system with clear water immediately
after using detergent solutions.
• Clean filter screen on detergent inlet line
periodically.
• Flush the pressure washer system with antifreeze
if storing for an extended period of time, refer to
Storage for details.
Gasoline Engine
Refer to the provided Gasoline Engine Manual for
recommended maintenance.
Oil Burner
Blower Motor: Inspect the motor brushes for wear every
250 hours of operation and replace when 1/8" to 1/4"
brush material remains. DO NOT allow the brushes to
Figure 10 - Pump Lubrication
wear out completely or motor damage will occur. Refer to
Figure 13. The motor bearings are permanently lubricated
and will not require any additional lubrication.
Relief Valve
WARNING: The relief valve on this pressure washer
has been factory set and sealed and is a field nonad-
justable part. Tampering with the factory setting may
cause personal injury and/or property damage, and
will void the manufacturer warranty. For replacement
parts refer to Figure 18.
Unloader Valve
WARNING: The unloader valve on this pressure
washer has been factory set and sealed and is a field
nonadjustable part. Tampering with the factory set-
ting may cause personal injury and/or property dam-
age, and will void the manufacturer warranty. For
replacement refer to Figure 15.
Burner Fuel Filter
Drain any water which has accumulated in fuel filter
and clean or replace filter element as needed. Refer to
Figure 13.
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 eventually 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.
Hour Meter
An optional hour meter (P/N 783865) is available for use
on the Model 1065A/1065SS. This hour meter will monitor
the total hours of operation of the pressure washer to
signal when routine maintenance is required.
Battery
Refer to battery manufacturer’s literature for recom-
mended maintenance.
