Initial setup and operation of your new pressure washer

Inspection for freight damage	When you receive your pressure washer, be sure you check for concealed freight damage. Any damage should be noted with the delivering carrier. If you have any questions related to freight, call the 800 number listed in the front of the manual.
Inspection of oil levels	Check all oil levels in the pump or engine, if applicable. Failure to check all levels will result in equipment damage. Most pumps are shipped with oil from factory and the crankcase are sealed, you may have to remove a shipping plug and install a dipstick in the pump. Most engines are shipped without oil, be sure to check these oil levels.
Water supply	Your water supply must provide water to the equipment that exceeds the Gallon Per Minute (GPM) rate of your machine. You can check your GPM by using a five gallon bucket and a timer. If your machine is five GPM or less and the bucket fills in less than a minute you have adequate supply. Some systems are effected by things like washing machines, livestock watering systems, and flushing toilets. Be sure the supply is still adequate when these operations are taking place. The water temperature cannot exceed 145 degrees Fahrenheit. Water pressure should not exceed 60 PSI. Failure to secure adequate water supply will result in pump damage. Do not run pump dry.
Water quality	Your water should not contain particles larger than 80 microns. Although there are small filters installed on pressure washers that filter the water, they can only filter poor quality water for a short period of time before they clog. Clogging would result in damage to the machine. Therefore you should insure no sand or scale particles are present in the water supply.
Supply hose	Hook a garden hose from the hydrant to the machine, when doing this be sure to check the inlet water filter or screen. This hose should be at least 5/8' diameter and a length at least 15 feet. This 15 foot length helps isolate the water supply from pulsations from the pump. Many states require a Vacuum Break or backflow preventer be installed at the hydrant, before the garden hose, to insure the water source cannot be contaminated. Be sure to check local and state regulations upon installation.
Purge air	Turn on the water supply and open the trigger gun, this will purge all the air from the system. Look for water leaks and stop any leak found. Leaks can cause erratic pump behavior.
Burner fuel	Turn equipment off and allow time to cool before refueling. Fill the burner tank labeled 'fuel'. Be sure the fuel is clean and free from moisture and particles. Use only No. 1, No. 2 or kerosene, no other fuel should be used! There is a fuel filter in the line. Check this filter prior to operation. Do not run fuel pump dry, doing so will damage the fuel pump.
Pump	Prior to starting the motor, check the oil in the pump. Be sure it is at the proper operating level and that the correct oil is being used. Check the pump breakdown for the proper type of oil.

Initial setup and operation of your new pressure washer, cont.

During operation	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.
Interchange-able tips	Your machine is supplied with interchangeable spray tips. The colored tips are for high-pressure 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 property and persons may occur.
Chemical injector use	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. The chemical injector will only open up and allow chemical into the line when the forward handle (see wand breakdown page 10) on the wand is turned counter clock wise. This enables the pressure to drop to approximately 250 PSI and draw chemical, this is a valve that allows the water to flow through the wand and through the chemical tip. The rate of injection can also be set by turning the knob that the clear vinyl tube attaches to. Be sure to flush injection system with clear water after use.
Calibration	If an accurate injection rate is desired, use this formula.(GPM x 128) / ounces drawn in one minute = x: 1IE: If a 2.0 GPM machine draws eight ounces of chemical in one minute: 2 x 1288 = 32:1

Shut down procedure

Storage	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.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.
Winter storage	If you are going to store the machine for extended period of times in cold climates be sure to winterize the equipment. A fifty percent anti-freeze solution may be drawn in through the inlet of the pump using a short remnant 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.
Pump	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).

Despite the complexity of your power washing equipment, a number of common complaints stem from relatively simple problems. With guidance, the user can identify and remedy many common problems.

Always disconnect the power supply before attempting to service any equipment.
