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 wear out completely or motor damage will occur. Refer
to
Figure 22
. 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 non-
adjustable part. Tampering with the factory setting
may cause personal injury and/or property damage,
and will void the manufacturer warranty. For replace-
ment parts refer to Figure 15.
Unloader Valve
WARNING: The unloader valve on this pressure
washer has been factory set and sealed and is a field
non-adjustable part. Tampering with the factory
setting may cause personal injury and/or property
damage, and will void the manufacturer warranty. For
replacement refer to Figure 18.
Burner Fuel Filter
Drain any water which has accumulated in fuel filter and
clean or replace filter element as needed. Refer to
Figure 21.
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 925A/925SS. 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.
