Shut down procedure
Initial setup and operation of your new pressure washer, cont.
The pressure was set at the factory during the testing procedure, no adjustments to the machine
should be required for operation. During operation the burner may cycle on and off. The
adjustable thermostat may be set to desired temperature. Water temperature will not exceed 190
degrees, the safety switches will shut the burner down.
During operation do not leave the
machine running for more than two minutes without the trigger gun being pulled.
Although your machine has a by-pass valve on it and may have a thermal relief system, this can
cause extensive pump damage.
If machine will not be discharging water for more than
two minutes, shut the machine off.
Your machine is supplied with interchangeable spray tips. The colored tips are for high-pres-
sure rinse at different spray angles. The red tip sprays at zero degrees; yellow, fifteen degrees;
green, twenty-five degrees; and white, forty degrees. The yellow tip is used for most standard
applications.
Be sure the quick coupler is fully engaged before pulling the trigger gun.
Failure to do so may result in the tip becoming a projectile and may be lost and damage to prop-
erty and persons may occur.
Your pressure washer is supplied with a downstream chemical injector. The 1/4” clear vinyl
tube is to be inserted into the desired chemical to apply. Be sure the nozzle with the large hole,
approximately 1/8”, is used when desiring to inject chemical. The chemical injector will only
open up and allow chemical into the line when this tip is used. This tip enables the pressure to
drop to approximately 250 PSI to draw chemical. This is done by turning the side handle on
the wand, this is a valve that allows the water to flow through the wand and through the chem-
ical tip. The rate of injection can also be set by turning the knob that the clear vinyl tube attach-
es to.
Be sure to flush injection system with clear water after use.
If an accurate injection rate is desired, use this formula.
(GPM x 128) / ounces drawn in one minute = x: 1
IE: If a 2.0 GPM machine draws eight ounces of chemical in one minute: 2 x 128
8
= 32:1
1. Turn off the power switch on the burner. Continue to run the pressure washer and pull
the trigger to circulate water through to cool the coil.
2. After several minutes when water is cool, shut off the pressure washer motor or engine.
3. Shut off water supply and disconnect garden hose.
4. Be sure to double check for water leaks or oil leaks that should be repaired before the next
operation.
If you are going to store the machine for extended period of times in cold climates be sure to
winterize the equipment. If you have a gas engine, be sure to treat the fuel for storage. A fifty
percent anti-freeze solution may be drawn in through the inlet of the pump using a short rem-
nant of garden hose. This fluid should be run through the pump and coil. When the fluid is
discharged from the coil discharge your machine is winterized.
Do not allow machine to
freeze.
The pump oil should be changed after the first fifty hours of operation, then every year for
average service or more frequently for extensive use or hostile environments (dusty or high
moisture).
