Inspection for freight damage
When you receive your commercial 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 our 866 toll free number immediately.
Inspection of oil levels
Check all oil levels in the pump or engine if applicable. Failure to check all levels will result in pressure washer damage. Most pumps are shipped with oil from factory and the crankcases are sealed; you may have to remove a shipping plug and install a dipstick in the pump. Oil type is stated on the pump breakdown and in the engine book.
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 5 Gallon bucket and a timer. If your machine is 5 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 of toilets. Be sure the supply is still adequate when these operations are taking place. The water temperature cannot exceed 145 Degrees Fahrenheit on the standard models and 180 degrees Fahrenheit on the high temperature models and the pressure should not exceed 60 PSI. Failure to secure adequate water supply to your commercial pressure washer 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 power washers that filter the water, they could only filter poor quality water for a short period of time before they clog. This 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’ length helps isolate the water supply from pulsations from the pump. Many states require a Vacuum Break or back flow prevention 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.
Electrical Supply
A circuit dedicated only to the pressure washer is recommended. This circuit should be installed by a licensed electrician and checked to supply adequate voltage Under Load. Sometimes the distance from the panel is to long, the wire size is to small or the voltage is initially to low, this will cause the GFCI or Thermal to trip. If the GFCI trips or the thermal overload on the motor trips consult factory. Plug your cord into the receptacle. DO NOT USE EXTENSION CORD!
Pump
Prior to turning on the power switches or your engine check the oil level in the pump.
Turn on Power
Turn on the power switch. Pull trigger gun and check for adequate pressure.
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 do not leave the machine running for more than 2 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 2 minutes, shut the machine off.
