Product Manual

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 the top 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 page 9).
3. CONNECT HOSE AND GUN ASSEMBLY.
4. 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. 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:
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 46-60 235 CCA. 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 the equipment’s requirements. 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.)
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 rewind starter, pull
cord rapidly.
Diesel Engine Units:
Turn power switch to heat the glow plugs for a
maximum of 30 seconds and release. Turn the
power switch to the 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 BURNER:
To create hot water on high pressure washers
equipped with heat exchangers, release the trigger
on the gun, turn the burner to the “on” position, and
turn the thermostat to the desired temperature.
Squeeze the trigger on the spray gun and the
burner will begin heating the water. It will stop firing
whenever the water spray is off or if the
temperature setting is exceeded.
5. STEAM: (If Equipped)
Insert green 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:
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. 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. If equipped with By-pass-cool system, a
small portion of the bypass water is routed back
through the float tank to keep the pump cool.
Warning: Do not leave in bypass for longer
than five minutes to prevent pump from
overheating. Shut off unit when not spraying
water.
Warning: Cool down burner before shutting off.
