prior to the detaching of the high pressure hose.
22. Never tie knots or kink the high pressure hose as damage
could result. Inspect the high-pressure hose regularly. Replace
the hose immediately if it is damaged, worn or shows any signs
of cracks, bubbles, pinholes, or other leakage. Never grasp a
high-pressure hose that is leaking or damaged.
23. Do not operate or store this product in temperatures below
40°F (4°C). Freeze damage is not covered by the warranty.

Glossary
Bypass mode: Allows water to re-circulate within pump when the gun
trigger is not pulled.
Chemical hose: Feeds cleaning agents into the pump to mix with the
water. Refer to Chemicals and Cleaning Solvents.
Chemical injection system: Mixes cleaners or cleaning solvents with
water to improve cleaning effectiveness.
CU: Cleaning Units. GPM multiplied by psi. (GPM x PSI = CU)
GPM: Gallons Per Minute. The unit of measure for the flow rate of
water.
PSI: Pounds per Square Inch. The unit of measure for water pressure.
Also used for air pressure, hydraulic pressure, etc.
kPa (kilopascal): Metric pressure measurement. 1 kilopascal equal
1000 pascals.
Quick-connect spray wand: Allows the user to quickly change out
high-pressure nozzles. Refer to Spray Wand Nozzles.
Thermal relief valve: When the temperature inside the pump rises
too high the valve will open and release a gush of water in an effort to
lower the temperature inside the pump. The valve will then close.
Water supply: All pressure washers must have a source of water. The
minimum requirements for a water supply are 20 psi (138kPa) and
5gallons per minute.
