INSTALLATION INSTRUCTIONS
(continued)
Dirt Killer endorses the use of UL approved ground
fault interrupters (GFI). (Warranty will be void if a
GFI equipped model has the GFI plug cut off).
7. If your pressure washer is gasoline driven,
always check and fill the gas tank prior to starting.
WARNING
- Filling the gasoline tank while the
pressure washer is running may ignite the fuel and
cause a fire. Never fuel a pressure washer while it
is running!
8. If your pressure washer is a fuel-fired hot water
pressure washer, make sure burner fuel tank is
filled with diesel fuel.
OPERATING INSTRUCTIONS
1. Turn on the inlet water and purge air from the
system by squeezing the gun trigger.
2.
For gas powered pressure washers
: Turn
gas valve on, close choke lever per manufacturers
instructions, advance throttle lever approximately
1/3 of the way open, and turn the engine switch to
ON. Start engine with the pull cord. (For easier
starting, squeeze the trigger on spray gun as you
start the unit). Note - if unit has optional electric
start turn switch to start and crank the engine until
it runs. Allow the machine to warm-up a few
seconds. Advance the throttle to full. You are now
ready to clean.
For electrically powered pressure washers
:
When starting an electric pressure washer
pull
the gunjet trigger
as you turn on the machine to
insure longer motor life. To operate the pressure
washer turn or press the switch to the ON position.
If the pressure washer does not come on when
switched on, and the pressure washer is equipped
with a the ground fault circuit interrupter (GFCI),
then reset the GFCI by pressing the Reset button
located on the GFCI.
3. Pull the trigger on the gun jet to clean with the
pressure washer.
4. If the pressure washer is equipped with a thirty
second time delay. After releasing the trigger, the
pressure washer motor will run for 30 additional
seconds and then shut off. To turn the pressure
washer on again, re-trigger the gun jet.
WARNING
- if the pressure washer equipped with
auto on/off is leaking at any place in the system
(gun jet, hose, water inlet, etc.) this auto-shut off
system will not function properly. Fix the leaks
immediately or consult with a technician before
using the pressure washer.
For hot water pressure washers
: After starting
either the gas engine or electric motor, allow the
machine to warm-up before switching on the
burner . Adjust the temperature control knob to
desired temperature (Max. water temp is 210˚) on
hot water burner units.
3. Dirt Killer pressure washers are equipped with
downstream, low pressure soap injectors. To draw
chemical/detergent, be sure the pick-up tube is
inserted into the chemical container with the tube
submerged in the solution. Change nozzle to the
soap nozzle (nozzle with black plastic cover and
large orifice); or if using a Variojet nozzle, push the
nozzle body to the forward position and squeeze
the gunjet trigger. The gauge will register a couple
hundred pounds of pressure and chemical/soap
will mix into water stream at a 10-1 ratio. Soap will
take several seconds to pass through the high
pressure hose. Always allow the cleaning
chemical time to dwell on the surface to be
cleaned to insure that the chemical's active
ingredients can do their job.
WARNING
- Do not let the chemical dry on the
surface to be cleaned. Chemicals that are allowed
to dry on the surface may cause damage.
CHEMICALS
The exit side or down stream chemical injector
allows you to apply chemical without the
chemicals coming into contact with the pump. Use
the downstream injector to apply soap, pesticides,
acids, alkaline and plant protective agents.
