GROUNDING INSTRUCTIONS
This product must be grounded. If it should malfunction or breakdown, grounding provides a path of least resis-
tance for electric current to reduce the risk of electric shock. This product is equipped with a cord having an
equipment-grounding conductor and a grounding plug. The plug must be plugged into appropriate outlet that is
properly installed and grounded in accordance with all local codes and ordinances.
DANGER - Improper connection of the equipment-grounding conductor can result in a risk of electrocution.
Check with a qualified electrician or service personnel if you are in doubts to whether the outlet is properly
grounded. Do not modify the plug provided with the product - if it will not fit the outlet, have a proper outlet
installed by a qualified electrician. Do not use any type of adaptor with this product.

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.
Check oil levels in the pump. Failure to check levels will result in equipment damage. Most pump
are shipped with oil from factory and the crankcase are sealed, you may have to remove a ship-
ping plug and install a dipstick in the pump.
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 flush-
ing 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 MX models and 180 degrees
Fahrenheit on the MXD and Wall Mount models and the pressure should not exceed 60 PSI.
Failure to secure adequate water supply will result in pump damage. DO NOT RUN PUMP
DRY.
Your water should not contain particles larger than 80 microns. Although there are small filters
installed on pressure 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 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 backflow preventor be installed at the hydrant, before the garden hose, to
insure the water source cannot be contaminated. Be sure to check local and state regula-
tions upon installation.
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.
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 con-
sult factory. Plug your cord into the receptacle. DO NOT USE EXTENSION CORD!
Prior to turning on the power switches or your engine check the oil level in the pump.
Turn on the power switch. Pull trigger gun and check for adequate pressure.

Calibration
Hoses and
couplers
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 min-
utes 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.
Your machine is supplied with interchangeable spray tips. The black tip lowers your pressure and draws
chemical. The other tips are for high pressure rinse at different spray angles. Red is 0 degree, yellow
is 15 degree, green is 25 degree and white is 40 degree. The yellow tip is used for most standard appli-
cations. Be sure the quick coupler is fully engaged before pulling the trigger gun. Failure to do may
result in the tip becoming a projectile and may be lost or damage to property or persons may occur.
Your pressure washer is supplied with a downstream chemical injector with dual chemical selector. The
1/4” clear vinyl tube is to be inserted into the desired chemical to apply. Be sure to use the black, low
pressure nozzle 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. The injector can be turned on and off or the rate of injection can also be set by turning the
knob that the clear vinyl tube attaches to. See calibration below.
Be sure to flush injection system with clear water after use.
The chart below is an average ratio observed using water as the test fluid to draw through the injector
and serves only as a guide, your actual ratio will vary.
Setting on valve Injection Ratio
9 6:1
8 8:1
7 10:1
6 13:1
5 20:1
4 28:1
3 35:1
2 50:1
For better accuracy, calibrate using the following formula:
(GPM x 128) ÷ (ounces drawn in 1 minute) = x:1.
IE: If a 2.0 GPM machine draws 8 ounces of chemical in 1 minute: (2 x 128)
8 = 32:1
Factory supplied hoses are sized in length and diameter for best operational performance and sized
within the pressure capabilities. Additional hose added to the machine may change the performance of
the machine. Consult factory if you have any questions. When replacing or disconnecting the quick cou-
plers be sure the machine is shut off and relieve the pressure from all hoses.

Shut down procedure
1. Turn off the power switch on the pressure washer.
2. Relieve pressure on line by pulling trigger gun.
3. Shut off water supply and disconnect garden hose.
4. Be sure to check for water leaks or oil leaks that should be repaired before the next operation.
5. If you are going to store the machine for extended period of times in cold climates be sure to anti-
freeze the equipment. A 50% 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 when the fluid is
discharged from the pump discharge your machine is winterized. Do not allow machine to freeze.
The pump oil should be changed after the first 50 hours of operation, then every year for average ser-
vice or more frequently for extensive use or hostile environments {dusty or high moisture}
Water filters, hoses and fittings should be checked prior to every operation for cleanliness, leaks and
repair needs. Repair or replace as needed.

Troubleshooting - Common Problems and Solutions
Low nozzle pressure is a common complaint. In a majority of instances, low nozzle pressure is general-
ly caused by one of the following:
1. Plugged nozzle tip.
2. Inlet screen plugged.
3. Insufficient flow in gallons per minute (not pressure) to the pump.
4. Unloader valve stuck open due to debris lodged under the check valve ball.
5. Customer use of shut-off-type quick connectors.
6. Plugged hose.
7. Incorrect nozzle or soap tip installed.
Another complaint is that pressure surges. That is, when the trigger is pulled, pressure is satisfactory for
a moment then falls off. When the trigger is released, pressure builds up to normal levels. This is gen-
erally a sign that the water supply cannot provide the flow rate (gallons per minute) required by the
pump. Following are some possible solutions:
1. Make sure the supply is not restricted; that there are no under-sized fittings and the inlet screen is
unobstructed.
2. Make sure the flow rate of the water supply is sufficient for the pump. First, find the capacity of your
pump in gallons per minute (gpm) as shown in the Water Supply section on Page 5. Then determine
the flow rate of your supply by measuring the gallons that can be delivered in one minute. If your
supply does not deliver the gpm your pump requires, do not use the pump. It will suck air, causing
cavitation that can quickly damage pump components.
3. Check for leaks in the supply fittings. Any leak will cause the pump to draw air and perform poorly.
When a soap injector is not working properly, the problem is generally fairly easy to isolate. Check the
following:
1. Make sure the Black, soap tip is installed. Soap injectors will not work when high pressure nozzles
are installed.
2. Be sure that the soap injector valve is turned on, and turn selector valve to desired setting.
3. A piece of debris may be caught in the injector valve, injector ball valve, or orifice. Disassemble
and clean the injector.
User maintenance procedures include replacing valves and seal. Unloader components are not user
serviceable. Repairs involving unloaders and crankcase components should be referred to the factory or
a factory authorized repair center.
