PowerWasher RN2600 Operation Manual page 10

BASIC ELEMENTS OF AN
ENGINE
Refer to the engine manual for location
and operation of engine controls.
Choke Control: Opens and closes car-
buretor choke valve.
Starter Grip: Pulling starter grip oper-
ates recoil starter to crank engine.
Engine Switch: Enables and disables
ignition system.
PRESSURE WASHER
TERMINOLOGY
psi: Pounds per Square Inch. The unit
of measure for water pressure. Also
used for air pressure, hydraulic pres-
sure, etc.
GPM: Gallons Per Minute. The unit of
measure for the flow rate of water.
CU: Cleaning Units. GPM multiplied
by psi. GPM x psi = CU
Bypass Mode: Allows water to
re-circulate within pump when the gun
trigger is not pulled.
Allowing the unit to
run for more than
two minutes without the gun trigger
pulled could cause overheating and
damage to the pump.
Thermal Relief Valve (not shown)
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.
Chemical Injection System: Mixes
cleaners or cleaning solvents with
the water to improve cleaning
effectiveness.
Water Supply: All pressure washers
must have a source of water. The min-
imum requirements for a water supply
are 20 psi and 5 gallons per minute.
PRESSURE WASHER OPERATING
FEATURES
Pressure Adjustments
The pressure setting is preset at the fac-
tory to achieve optimum pressure and
cleaning. If you need to lower the pres-
sure, it can be accomplished by these
methods.
1. Back away from the surface to
be cleaned. The further away you
are, the less the pressure will be on
the surface to be cleaned.
2. Rotate the nozzle at the end of
the multi-adjustable spray wand
to widen the fan spray.
The wider fan spray will minimize
the pressure on the surface to
be cleaned.
