NOZZLE REVIEW
Various nozzles may be quick connected into the end of the adjustable
pressure dual lance to change the spray pattern or use the detergent
feature. When using Quick- connects (Q.C.), be certain the connection is
securely locked. If not, the high pressure water may shoot the nozzle from
the lance, causing severe injury or serious damage. To determine spray
fan, refer to the actual number stamped on the nozzle. The first two digits
indicate the spray fan in degrees, i.e., 00=0°, 15=15°, 25=25°, 40=40°.
1. The 0° nozzle (RED): This is a blasting nozzle. It delivers a very concentrated stream of water. Be cautious when using the straight narrow
stream. It is not recommended for use on painted or wood surfaces,
or items attached with adhesive backings. Uses: Removing weeds
from sidewalk cracks, stubborn stains from concrete, masonry, aluminum and steel, caked mud from equipment, and cleaning lawn mower
undersides.
2. The 15° nozzle (YELLOW): This is a chiseling nozzle. The spray should
be directed at a 45° angle to the surface and used like a scraper to
remove paint, grease and dirt. Uses: Surface preparation (removing
mildew stains and paint chips).
3. The 25° nozzle (GREEN ):
a. This is a flushing nozzle. This pattern is best suited for flushing dirt,
mud, and grime. Uses: Wet sweeping leaves from walk, curbs and
driveways, cleaning stable floors, washing swimming pool bottoms,
degreasing engines.
b. On units with steam option, this nozzle is used for 250°F Wet Steam
operation. This nozzle is sized for operation with the unloader and
steam valve (where applicable) to provide high pressure wet steam.
Replacement of this nozzle with an improperly sized nozzle may cause
operational problems with the machine.

operation
Operating Instructions
FLUSHING THE SYSTEM
1. This unit has a steel coil which, after setting, will cause the water remaining in the coil from the previous usage to turn brown or black. This
water must be flushed from the system before start-up. This procedure
should be performed without the gun and adjustable pressure dual
lance installed.
a. Verify the water supply is on.
b. Move the pump switch to the “ON” position to start the pumping unit.
c. Run the unit for 3-5 minutes.
d. Turn off machine.
e. Once the system is flushed, connect the trigger gun and adjustable
pressure dual lance to the high pressure hose.
CAUTION
BE CERTAIN THE HOSE, GUN & LANCE ASSY. ARE NOT
CONNECTED TO THE UNIT WHILE PRIMING THE PUMP. PRIMING
ALLOWS MINERAL DEPOSITS TO BE RELEASED FROM THE
SYSTEM WHICH WOULD OBSTRUCT OR DAMAGE THE GUN
AND NOZZLE ASSEMBLY RESULTING IN COSTLY REPAIRS.

operation
1. Refer to the “Safety Precautions” pgs. 7-11 before starting the unit.
2. Locate the Safety Decals on your unit and heed their warnings.
3. Ensure that the burner switch is in the “OFF” position.
4. Pointing the trigger gun in a safe direction, unlock the trigger gun and
squeeze the trigger. Brace yourself for possible gun kickback when
the pump starts.
5. Move the pump switch to the “ON” position to start the pumping unit.
6. Once the unit has started, perform the following procedures with the
gun open:
a. Inspect for system water and oil leaks.
b. Inspect high pressure hoses for leaks. If a leak is found, DO NOT
TOUCH HOSE AT LEAK!!! TURN UNIT OFF IMMEDIATELY! Replace
hose before using the unit. See “Risk of Injection” warnings, pg. 7.
Be sure that all damaged parts are replaced and that the mechanical
problems are corrected prior to operation of the unit.
7. At this point, the unit is operating as a cold water pressure washer.
Trigger the gun several times and try adjusting the water pressure by
rotating the grip on the dual lance. NEVER place hand or fingers in
front of the nozzle or look directly into the nozzle! High pressure water
creates a risk of severe injury!
8. Do not allow unit to operate in bypass mode (with trigger closed) for
more than three minutes without triggering the gun. Failure to follow
this simple rule can cause premature failure of pump packing seals,
resulting in costly pump repair.
9. Your pressure washer can deliver high pressure spray and a variety
of spray patterns using cold water. If you wish to use the hot water
application or cleaning with detergents, see pg. 23 for the correct
procedures.
1. Follow the steps outlined for “COLD WATER OPERATION.”
2. Move the burner switch to the ON position. On initial start-up, water
will begin turning hot in approximately 60 seconds and will reach
maximum temperature in approximately 3 minutes, provided the trigger remains squeezed. The burner will stop firing when the trigger is
released.
3. Set thermostat to the desired setting.
At this point, the unit is operating as a hot water pressure washer. Be
certain to be extremely cautious when adjusting the pressure and controlling the trigger gun/dual lance assembly to avoid the possibility of burns.
HOT WATER OPERATION
When cold water is being pumped into the heat exchanger and the
burner is on, condensation may form on the coil and drip. This will give
the appearance of a leaking coil particularly in cold humid weather.
29
operation
WARNING
THE WATER TEMPERATURE COULD BECOME VERY HOT DURING
HOT WATER OPERATION. BE CAUTIOUS WHEN ADJUSTING
PRESSURE OR CONTROLLING THE TRIGGER GUN/ LANCE
ASSEMBLY.
NOTICE
The burner is equipped with a safety lock-off device. If the pilot fails
to ignite within 60 seconds, the gas valve locks OFF. Simply release
the trigger for approximately another 60 seconds and repeat. During
operation, the burner may cease and start occasionally because of the
thermostat setting.
CLEANING WITH DETERGENTS
NOTICE
If machine is equipped with remote box (es), read pg. 24 for information on detergent solenoid.
This feature is designed for use with mild detergents only. Since the
cleaning solution travels through the heat exchanger coil, do not use
corrosives as they will cause extensive damage as well as pose a
considerable safety hazard.
1. Be certain to wear protective safety attire as stated on pg. 23.
2. Prepare detergent solution according to label directions. (Never pump
acids, alkalines, abrasive fluids or solvents through the unit.)
3. Fully immerse the strainer end of the clear vinyl detergent hose into the
detergent solution.
4. Adjust the amount of detergent desired by turning the detergent
adjustment knob to the desired setting.
5. To apply solution, unlock the trigger gun and squeeze the trigger. In
a few moments a detergent/water mixture will exit the nozzle. Start
spraying the lower portion of the surface being cleaned and move up,
using long overlapping strokes. Applying from the bottom up helps
avoid streaking. Allow to soak briefly. Avoid working on hot surfaces
or in direct sunlight to minimize the chances of the detergent drying,
which may result in damaging surfaces. Be certain to clean a small
section at a time.
6. To rinse, turn the detergent adjustment knob to the OFF position. It will
take about 30 seconds to purge all detergent from the line. For best
rinsing results, start at the top and work down.
30
7. Siphon a gallon of water through the detergent system after each use.
This prevents the possibility of corrosion or detergent residue causing
mechanical problems during the next use.
operation
NOTICE
The detergent adjustment knob or detergent solenoid MUST by turned
to the OFF position when not in use or when the strainer is not totally
submerged in solution. If not, the pump will lose its prime resulting in
no spray discharge at the nozzle. This condition will damage the pump
over an extended time period.
SHUTDOWN
1. If the burner switch is still on, turn it off.
2. Squeeze the trigger and discharge the water for a period of three
minutes to cool the heat exchanger and high pressure hose.
(Insufficient cool down period of the high pressure hose will cause
excessive wear and eventual rupturing of the hose.)
3. Move the pump switch to the “OFF” position to stop the pumping unit.
If machine has the time-delay shut-down option, wait for timer to timeout and shut machine off. See below for more information on timedelay shutdown.
4. Trigger the gun momentarily to relieve trapped pressure.
31
OPTIONS
REMOTE BOXES
The remote box option allows the unit to be controlled from up to four
remote workstations. The remote stations are wired in parallel to allow
the operator to have full control of the unit from any station at anytime.
Detergents are controlled by a chemical solenoid added to the main unit
and control switches on the remote boxes.
The maximum run for the remote wiring are as follows:
14 Gauge Wire - 200 feet
16 Gauge Wire -100 feet
TIME-DELAY SHUTDOWN
The time-delay shutdown option provides an adjustable automatic
shutdown for the main unit. The factory presets the time-delay shutdown
interval at 2 1/2 minutes. This option overrides the operation of the pump
on/off switch for control of the pump motor shutdown.
AUTO START/STOP
The auto start/stop option provides an adjustable automatic shutdown
and a pressure switch to restart the unit automatically when the gun is
triggered. The factory presets the time-delay shutdown interval at 2 1/2
minutes. This option is not available with remote box option or flowactivated unloader option.
STEAM - 250°F
The 250°F steam option provides wet steam output from the unit. By
adjusting the steam valve on the main control panel for the unit and using
the included steam nozzle, 250°F steam is obtained. The sizing of the
steam nozzle is critical to proper operation of the option.

maintenance
Maintenance Instructions
PREVENTATIVE MAINTENANCE
LEAKS: Promptly eliminate any leaks found in the pumping system by
removing suspect parts, applying thread sealant to the threads and
reinstalling.
QUICK COUPLERS: There are o-ring seals inside the couplers which
will deteriorate. To replace, simply install a replacement o-ring to
correct the leak. (Additional o-rings can be purchased from your
dealer.)
NOZZLE: Water flow through the spray nozzle will erode the orifice,
making it larger, resulting in a pressure loss. Nozzles should be
replaced whenever pressure is less than 85% of the maximum. The
frequency of replacement will depend upon such variables as mineral
content in the water and number of hours the nozzle is used.
PUMP:
1. Change the pump oil after the first 50 hours of operation. After initial
change, every 3 months or 250 hour intervals are recommended.
If oil appears dirty or milky, changes may be required in greater
frequency.
2. Locate the pump oil drain hose.
3. Use an empty container to catch the oil and remove the plug from
the drain line.
4. Let all the oil drain from the pump and replace drain plug. Dispose
of used oil according to local, state and national regulations.
5. Fill the pump crankcase to the notch on the dipstick with pump oil
SAE20 or 30 non-detergent. Do not overfill.
BELT TENSION: Ensure unit is off. Remove the side panel or lift lid to
inspect the v-belt for wear and tightness. If the v-belt needs to be
replaced or tightened, follow the procedures listed.
Replacement:
1. Loosen the four pump mounting bolts (A).
2. Loosen the two alignment nuts approximately one inch on the
alignment bolts (B1 & B2).
3. Slide the pump toward the motor to loosen belts.
4. Remove and replace belt.
NOTICE
If using Teflon tape, be certain no tape gets inside any plumbing to
prevent the possibility of a plugged spray nozzle.
33
maintenance
Tighten: (If v-belt was not replaced, you will need to loosen the nuts on
the alignment bolts B1 and B2 before proceeding.)
1. Tighten B2 alignment bolt. The pump will shift to the left until there
is tension on the belt. Then tighten B2 nut.
2. Tighten B1 alignment bolt, until sheaves are straight. (Use a
straightedge for alignment.)
3. Push on the v-belt to check belt deflection for tension. There should
be 1/4” to 1/2” deflection for correct tension.
4. If sheaves are straight and tension is correct, tighten B1 nut and the
four pump mounting bolts (A).
5. If tension is not correct, repeat steps 6 and 7 until correct alignment
and tension is achieved. Tighten the four mounting bolts (A) when
completed.
6. Loosen B2 nut, tighten B2 bolt, tighten B2 nut.
7. Loosen B1 nut, tighten B1 bolt, tighten B1 nut.
