Hazardous Substance Alert
Always drain and flush the pump before servicing.
Always drain and flush the pump prior to returning
the Pump to Hypro for repair.
Never store a pump containing hazardous materials.
Prior to returning a pump for service or repair, drain
all liquids and flush the pump with a neutralizing
fluid; then, drain the pump again, and attach a tag or
written notice certifying that this procedure has been
done.
It is illegal to ship or transport any hazardous
chemical without United States Environmental
Protection Agency licensing.
Never use your hand to check the condition of
hydraulic lines or hoses. If hydraulic fluid penetrates
the skin, get medical help immediately. Failure to get
proper medical help may result in loss of limb or life.
The safest way to check hydraulic lines or hoses is
by holding a piece of cardboard next to the hydraulic
line or hose.
Do not pump at pressures higher than the maximum
recommended pressure.
Operate the Pump between a temperature range of
45o to 140o F [7o to 60o C].
Make certain that the power source conforms to the
requirements of your equipment.
Provide adequate protection in guarding around the
moving parts such as shafts and pulleys.
Disconnect the power before servicing.
Release all pressure within the system before
servicing any component.
Drain all liquids from the system before servicing.
Secure the discharge line before starting the pump.
An unsecured discharge line may whip, resulting in
personal injury and/or property damage.
Check all hoses for weak or worn condition before
each use. Make certain that all connections are tight
and secure.
Periodically inspect the pump and the system
components. Perform routine maintenance as
required.
Use only pipe, hose, and hose fittings rated for
maximum rated pressure of the pump or the
pressure at which the pressure relief valve is set at.
Do not use used pipe.
Do not use these pumps for pumping water or other
liquids for human or animal consumption.
Installation Requirements
Hypro’s Hydraulically-Driven Pressure Washer can be
installed on tractors with Closed Center and Load
Sensing Hydraulic Systems, or on Custom Open Center
Hydraulic Systems.
The required inlet conditions for the water pump can vary
from the flooded suction of a water tank to pressure from
a city water supply. The water supply must be capable
of supplying more than 4.0 gpm of water flow to meet the
pump requirements.
The pump comes equipped with an unloader valve and
bypass system rated for 2000 psi. When the trigger of
the gun is in the OFF position, the unloader allows water
to recirculate back through the pump. A thermal relief
valve is included to keep the pump from overheating
when it is in the bypass mode with the gun trigger in the
OFF position. For long pump life, do not allow the pump
to run more than five minutes with the gun trigger in the
OFF position.
