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 with a pressure between 25 and 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 9”x6”, 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.
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.
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.
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. 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.
6. BYPASS MODE: (if equipped): System will go into
bypass mode when machine is left running and trigger
gun is closed. Bypass mode is when the inlet water
coming into the pump re-circulates through the
unloader across the pump head. If left in bypass too
long
– more than five minutes – friction created by the
movement of the water will begin to heat the water at
a rapid rate. If equipped with a THERMAL DUMP
VALVE, water exceeding 145°F will cause the valve to
open allowing the cool water in to the pump. The
valve will reset itself when water temperature comes
down to a safe level. If equipped with a bulk water
tank, water can be bypassed back through the tank
allowing for a larger volume of water to be re-
circulated through the pump head thus reducing heat
on the pump seals. Warning: Do not leave in bypass
for longer than five minutes to prevent pump from
overheating. Shut off unit when not spraying water.
7. If unit is equipped with a downstream chemical
injector, connect the chemical injection assembly into
the high-pressure discharge hose quick connects.
Place the chemical pickup into chemical solution and
turn brass collar to adjust concentration. The
chemical will inject only when you drop the outlet
pressure by opening the valve on the dual wand or
changing to a low-pressure nozzle. Soap the surface
from the bottom up. Rinse and close chemical valve
when not in use.
