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 your
selling dealer.
Check all oil levels in the pump or engine if applicable. Failure to check all levels could 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 manual.
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 water supply systems are
affected 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.
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.
Hook a garden hose from the faucet to the machine, when doing this be sure to check the inlet water filter
or screen. This hose should be a least 5/8" diameter and a length at least 15 feet. This 15' length helps
isolate the water supply from pulsations from the pump.
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.
Prior to turning on the power switch or starting engine, check the oil level in the pump. The pump oil
should be changed after the first 50 hours of operation, then every 3 months or 300 hours of operation
thereafter for average service or more frequently for extensive use or hostile environments {dusty or high
moisture}.
Turn on the power switch. Pull trigger gun and check for adequate pressure.
Water filters, hoses and fittings should be checked prior to every operation for cleanliness, leaks and repair
needs. Repair or replace as needed.
Many states require a Vacuum Break or back
flow preventor be installed at the faucet, before the garden hose, to insure the water source cannot be
contaminated. Be sure to check local and state regulations upon installation.
