INSTALLATION & PREPARATION
NOZZLE REVIEW:
Various nozzles may be quick-connected into the end of the wand to change
the spray pattern or use the detergent feature. When using Quick Connects
(Q.C.), be certain the connection is securely locked. If not, the high pressure
water may shoot the nozzle from the wand, causing severe injury or serious
damage. To determine spray fan, refer to the actual number stamped on the
nozzle. The rst two digits indicate the spray fan in degrees, i.e.; 15=15°,
25=25°, 65=detergent/low pressure.
1. The 15° nozzle (YELLOW): This is a chiseling nozzle. The spray should
be directed at a 45° angle to the surface and used like a scraper to remove
paint, grease and dirt. Uses: Surface preparation (removing mildew stains
and paint chips).
2. The 25° nozzle (GREEN): This is a ushing nozzle. This pattern is best
suited for ushing dirt, mud, and grime. Uses: Wet sweeping leaves from
walks, curbs and driveways, cleaning stable oors, washing swimming
pool bottoms, degreasing engines.
3. The 65° nozzle (BLACK): This is a low pressure detergent application
nozzle. This broad spray pattern distributes solution over vast areas under
low pressure. Uses: Detergent application, misting or rinsing.

INSTALLATION & PREPARATION
WATER INLET STRAINER
WATER SUPPLY:
1. Select a water supply hose which is a quality grade of garden hose measuring
at least 3/4” ID and no longer than 50 feet.
2 Check the water inlet strainer to ensure it is clean and free of any obstructions.
As a strainer becomes obstructed, it restricts proper ow of water to the
pump. This can result in cavitations which will cause premature failure of
pump packings.
a. Using a screw driver, remove the screen from the water inlet.
b. Clean or replace with Mi-T-M #19-0001 if necessary.
3. Connect the hoses.
a. Connect one end of the water supply hose to the water inlet of the
unit.
b. Connect the other end of the hose to your pressurized water supply.
NOTE 1: Do not use a non-pressurized water supply (i.e. from a pond or well)
with this unit.
NOTE 2: When connecting the water inlet to the water supply mains, local
regulations of your water company must be observed. In some
areas, the unit must not be connected directly to the public drinking
water supply. This is to ensure there is no feedback of detergents
into the water supply. (Direct connection is permitted if a backow
preventer is installed. Check with local authorities for approval.)
c. Connect the high pressure discharge hose to the water outlet of the
unit.
d. Securely connect the other end of the hose to the gun assembly. (A
wrench may be required on some models.)
e. Connect the wand assembly to the gun/hose assembly.
4. Follow the incoming water requirements listed below:
a. Water pressure must be a minimum of 25 pounds per square inch (PSI)
and a maximum of 125 PSI. (A typical outdoor faucet will
generally supply this PSI if turned completely “ON”.)
b. Incoming GPM must be approximately one gallon more than the
outgoing GPM stated on the pressure washer nameplate. (You can
check GPM by timing how long it takes to ll a 5 gallon container.)
c. Incoming water temperature must not exceed 125°F. Excessive pump
damage may result if the water temperature exceeds this acceptable
level.
5. Never allow the unit to operate without the incoming water line attached and
the water supply completely turned on.
UNLOADER:
CAUTION
RISK OF UNIT DAMAGE!
DO NOT OVERTIGHTEN THE
UNLOADER. BREAKAGE COULD
RESULT IN IMMEDIATE LOSS OF
WATER PRESSURE AND COSTLY
REPAIRS.
14 GP-SERIES Operator’s Manual
The unloader is equipped with an adjustment knob to adjust the pressure. Should
less pressure be required, simply turn the adjustment knob counterclockwise.
To set back to maximum, turn adjustment knob completely clockwise. DO NOT
OVERTIGHTEN!
THERMAL RELIEF VALVE:
To ensure the water temperature does not exceed acceptable levels, never allow
the pressure washer to operate in the bypass mode (with the unit running and
the trigger gun closed) for more than three minutes.
A “Thermal Relief Valve” has been added to this unit to protect the pump. It
may begin to open and release water if the water temperature in the pump has
exceeded 140°F. This will allow fresh, cool water to enter the system.
