HOT WATER PRESSURE WASHER
OPERATOR’S MANUAL
97-6131, 97-6140 • Rev. 3/04
Electrical:
This machine, when installed, must be electrically
grounded in accordance to local codes. Check for proper
power supply using a volt meter.
Placement:
Do not locate near any combustible material. Keep all
flammable material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from floor and
walls. (Two feet away from walls should be adequate.)
Water Source:
The water source for the pressure washer should be sup-
plied by a minimum 5/8" I.D. garden hose with a city wa-
ter pressure of not less than 30 PSI. If the water supply
is inadequate, or if the garden hose is kinked, the at-
tached pressure washer will run very rough and the
burner will not fire.
Connection:
Connect the wand, nozzle, hose and spray gun (where
applicable). On pipe thread connections, use teflon tape
to avoid water leaks. (See Component Identification).
Venting:
Adding exhaust vent pipe to your oil fired burner is not
recommended because restricted air flow causes car-
bon build-up, which affects the operation, and increases
maintenance on the coil. If a stack must be used, refrain
from using 90° bends. If the pipe can not go straight up
then use only 45° bends and go to the next size pipe.
The overall pipe length must not exceed 6 feet in length.
STARTING AND OPERATING
INSTRUCTIONS
To Start:
1. STOP! Read operator’s manual
before operating. Failure to read
operation and warning instruc-
tions may result in personal in-
jury or property damage.
2. Connect water supply hose and
turn on water.
3. Check fuel tank and pump oil
levels.
4. Connect high pressure hose to discharge nipple by
sliding quick coupler collar back. (If detergent is to
be applied, insert a detergent injector as shown in
Component Identification).
5. Insert quick coupler onto discharge nipple and se-
cure by pushing quick coupler collar forward.
6. Securely attach the desired high pressure nozzle into
wand coupler as described in steps 4 and 5.
7. Connect the power cord into the proper electrical out-
let, then push in the GFCI reset button. (Refer to
serial plate for information.)
8. Grip spray gun handle securely and pull trigger. Then
turn variable pressure control handle counterclock-
wise.
9. Turn switch to pump position. When a steady stream
of water flows from the spray gun and wand the ma-
chine is ready for cold water cleaning by turning the
variable pressure control handle clockwise to raise
the pressure.
10. For hot water washing, turn the switch to the burner
position. (The burner will light automatically when
the trigger on the spray gun is pulled.)
To Stop:
1. If using the detergent injector, place the detergent
hose in a bucket of water allowing detergent to be
flushed from system.
2. Turn burner switch off and continue spraying water,
allowing the water to cool.
3. After water has cooled to less than 100°F, turn the
attached pressure washer off.
4. Turn garden hose water off. Open the spray gun to
relieve remaining pressure.
5. Protect from freezing.
OPTIONAL EQUIPMENT
Auto Start/Stop Timer Operation
Once the pump switch is turned on, simply triggering the
spray gun is all it takes to start the machine. Once the
trigger is released the timer will let the machine bypass
water for 15 seconds. It also starts an internal 5 to 60
minute lockout timer. This feature is totally adjustable by
the operator by adjusting the knob at the top of the timer.
We recommend setting the timer for 15 minutes. To re-
set the lockout feature, operator must trigger the spray
gun for 10 full seconds.
PREVENTATIVE MAINTENANCE
1. Use clean fuel — kerosene, No. 1 home heating fuel
or diesel fuel. Clean or replace fuel filter every 100
hours of operation. Avoid water contaminated fuel as
it will seize up the fuel pump. De-soot coils monthly.
Use an additive if diesel is being used.
2. Check to see that the attached pressure washer wa-
ter pump is properly lubricated.
3. Follow winterizing instructions to prevent freeze dam-
age to pump and coils.
4. Always neutralize and flush detergent from system
after use.

MANUAL THOROUGHLY
PRIOR TO USE.
