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.
AVERTISSEMENT: Une modification non autorisée de
la machine ou l'utilisation de pièces de rechange non
approuvées peut causer des lésions corporelles et/ou
des dommages à la propriété, et annulera la garantie
du fabricant.
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 manu-
facturer's mix recommendations.
3. Immediately after using detergent solutions the
system should be flushed thoroughly with clear
water.
4. Clean strainer screen on detergent line periodi-
cally.

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

cette laveuse à pression a été réglée en usine, puis
scellée, et est une pièce non réglable. L'altération du
paramètre de l'usine pourrait causer des lésions
corporelles et/ou des dommages à la propriété, et

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.

Refer to battery manufacturer’s literature for recom-
mended maintenance
