Maintenance
WARNING: Unauthorized machine modification or
use of non-approved replacement parts may cause
personal injury and/or property damage and will
void the manufacturer warranty.
Pump
Use HOTSY Pump Oil (8.923-422.0) or equivalent
10W-40 Non-Foaming oil for pump crankcase.
Crankcase must be filled to the full mark on the dipstick
or 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 50 hours of operation. After
that, replace oil every year or 500 hours, whichever
comes first.
DO NOT:
1.
Pump acids.
2.
Fail to winterize in freezing temperatures.
3.
Allow pump to run dry.
4.
Allow machine to run with trigger gun closed for
more than 3 minutes at any one time or damage to
pump may occur.
DO:
1
. Use a water softener on the water system if known to
be high in mineral content.
2. Use only high quality detergents and follow manufac-
turer's mix recommendations.
3. Immediately after using detergent solutions the sys-
tem should be flushed thoroughly with clear water.
4. Clean strainer screen on detergent line periodically.
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 setting may cause personal injury and/or
property damage, and will void the manufacturer
warranty.
Burner Fuel Filter
Drain water that has accumulated in fuel filter and clean
filter element as needed.
Heating Coil
Coil De scaling:
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 de scaling is needed.
Coil De sooting:
Poor grades of fuel oil or inadequate
combustion air will cause heavy soot buildup on the
outside surface of the heating coil. This will restrict the
airflow through the coil, further aggravating the soot
buildup. Contact your local service center when
de sooting is needed.
Engine
Refer to
engine manual
provided with this pressure
washer for recommended maintenance.
Oil Burner Blower Motor
The motor bearings are permanently lubricated and will
not require any additional lubrication.

battery manufacturer’s literature
for recom-
mended maintenance
