Removal of Soot and Heating Coil
In the heating process, fuel residue in the form of soot
deposits may develop between the heating coil pipe
and block air flow which will affect burner combustion.
When soot has been detected on visual observation,
the soot on the coil must be washed off after following
the coil removal steps.
Relief Valve
WARNING: The relief 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.
For replacement parts refer to exploded views.
AVERTISSEMENT: La soupape de décharge sur
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
annulera la garantie du fabricant. Pour des pièces
de rechange, se référer aux vues éclatées.
This safety valve must be inspected and tested
annually.
Fuel
Use clean fuel oil that is not contaminated with water
and debris. Replace fuel filter and drain tank every 100
hours of operation.
Use No. 1 or No. 2
Heating Oil (ASTM
D306) only.
NEVER
use gasoline in your
burner tank. Gasoline
is more combustible
than fuel oil and could
result in a serious
explosion.
NEVER
use
crankcase or waste oil
in your burner. Fuel
unit malfunction could result from contamination.
Ignition Circuit
Periodically inspect wires, spring contact and elec-
trodes for condition, security and proper spacing.
Transformer test:
(CAUTION 10,000 VOLTS)
use defect free insulated
screwdriver and keep fingers off blade! Lay blade
across one contact: OK if arc will span 1/2" between
end of blade and other contact.
