BEFORE START UP: Read all instructions
1. CHECK PUMP OIL: Check pump oil by locating the
oil view window. Depending on your pump model, fill to
the red dot or to center of the site glass window.
2. CHECK FLUID LEVELS: Check engine oil and
coolant levels if unit is so equipped. (See the
maintenance schedule on back page).
3. CONNECT HOSE AND GUN ASSEMBLY.
CONNECT THE WATER SUPPLY & TURN WATER
ON: Maintain an adequate supply of water using a ⅝”
to ¾” I.D. hose (or ¾“ steel pipe for Natural Gas heated
HN models) with pressure between 25 & 60psi.
4. Burner power switches should be “off” before
starting. If tank fed, be sure there is water in the tank
and the valve is switched for supply tank feed. Do not
run dry.
5. BATTERY INFORMATION (when equipped):
Batteries are available through your dealer or local auto
parts store. Depending on the type of battery you
purchase, you may have to fill it with electrolyte. WEAR
EYE PROTECTION!
We recommend deep cycle batteries for machines
equipped with 12vdc powered burners. If the opening
on your battery box measures 8.5”x5.5”, select
U1L/GTH 235 CCA. If the opening measures 8”x12”,
use group 24 battery. Always connect the positive
battery cable before the negative and coat the battery
terminals with corrosion inhibitor to prevent corrosion.
Do not reverse polarity.
6. If wheel kit, accessories, or discharge hose are not
installed, see your local dealer for instructions &
installation.
7. NATURAL GAS / PROPANE GAS – Connect gas
supply using appropriate shut off cock and
recommended gas plumbing procedures; including the
use of a soap or lead detections solution on all fittings.
(Contact your gas supplier) A debris drop pipe is
required before the inlet of gas valve. Note that a
draft diverter is not included as a standard feature with
the machine. Draft diverters are required on HN
models. Operation without draft diverter may result in
excessive carbon monoxide output, incorrect
combustion, and inefficient heating. Gas regulator, gas
and water supply lines are not included with the
machine.
OPERATION:
1. STARTING:
Electric Powered Units: Connect power supply and
ensure that all wiring connections and voltages are of
sufficient rating to comply with equipment requirement.
Turn pump power switch on. If unit is equipped with
auto-start, keep all power switches off when left
unattended. (Unit will only turn on when trigger gun is
pulled.) Press the reset button to start motor if
equipped with a wash station remote.
Gasoline Engine Units: Turn engine power switch to the
on position, choke if necessary and turn key to start
position only until engine starts. On units with a recoil
starter, pull cord rapidly, until the engine starts.
Diesel Engine Units: Turn power key switch to the left
till the red glow plug indicator light goes off and then
release (maximum 30 seconds). Turn the power switch
to the (right) start position only until engine starts. (Do
not use starter fluids.)
2. PURGE AIR FROM SYSTEM:
Squeeze the trigger on the spray gun until a constant
stream of water comes out. (Purging works best with
nozzle removed from wand and/or dual wand in the low-
pressure mode.)
3. SELECT DESIRED NOZZLE
Connect nozzle securely to spray wand. If equipped,
close pressure-adjusting knob on dual wand. Hold gun
firmly, squeeze trigger for high-pressure spray.
CAUTION – Gun kicks back – hold with both hands.
WARNING – risk of explosion – DO NOT spray
flammable liquids.
4. START HEATER / BURNER:
a. Diesel heated: To create hot water on high
pressure washers equipped with heat
exchangers, release the trigger on the gun then
turn the burner to the “on” position.
b. Natural gas/Propane heated: equipped with an
automatic lighting pilot with a 90 second lockout.
If burner does not light within 90 seconds, turn
burner switch off, then on again to start ignition
sequence over.
c. All electric HE Series: equipped with an automatic
staged heater start up. Engage “HEAT 1” and
“HEAT 2” switches ON. Heat 1 will engage first
after 2 seconds allowing the amp load on the
pump motor to stabilize, then after 3 seconds Heat
2 will engage. This staged startup reduces the
high amp load on the power supply. Full heat rise
is normally accomplished within 1½ to 2 minutes.
d. Turn the thermostat to the desired temperature.
Squeeze the trigger on the spray gun and the
burner/heater will begin heating the water. It will
stop heating whenever the water spray is off or if
the temperature setting is exceeded. Heat rise will
vary depending on the inlet water temperature and
environmental conditions.
5. STEAM: (If Equipped) Insert steam nozzle and turn
thermostat to 250° steam setting. The steam nozzle is
sized for approximately 25% less water volume than the
hot water mode.
