INLET WATER SUPPLY REQUIREMENTS
1. Inlet water supply must be a minimum of 20 PSI (1.4
bar).
Attempting to operate the washer with less than
adequate water supply will cause rapid wear of
packings, valves and bearings that will dramatically
shorten pump life. Symptoms of inadequate water
supply are pump shuddering and attening of the
supply hose.
2. Inlet water ow must be at least 125% of pump rated
ow (see table below). Check volume by timing how
long it takes to ll a 5 gallon (19 L) container. For
example, a ow rate of 3.0 GPM would ll a 5 gallon
container in 5/3 minute (100 seconds).
3. Water supply hose should be a good grade of garden
hose with a minimum I.D. 5/8 in. (16mm) and no longer
than 50 ft. (15.24 m). If longer supply hose must be
used, check to be certain ow is at least equal to the
“GPM Supply Required” value listed at the bottom of
this page for your washer.
4. If non-pressurized (static draw) water supply is used,
check to be certain ow is at least 125% of pump
rated ow (see table below). In static draw situations,
water ow rate (GPM) can be increased by elevating
the water supply tank or changing to a larger inside
diameter water supply hose.
5. Adding on extension to the supply hose will reduce
water ow rates. Check for adequate water ow rate
each time an extension is added. Water ow rates
can be increased by using the largest possible internal
diameter supply hose.
PIC4-092299R0
IMPORTANT: Inlet water temperature must not be more
than 125° F (60° C). Damage to the pump
may result.

Operating the Washer
8" - 10"
(2 0-25 cm)
CLEANING HORIZONTAL SURFACES
Move nozzle wand from side to side. Direct spray at an
angle to force debris ahead and away from the cleared
area.
Depending on the material to be removed and nozzle
pressure, hold nozzle end 8 to 10 inches (20 to 25 cm) from
the surface and use slow, overlapping strokes. If debris
is easy to remove, move nozzle back to cover more area
for faster cleaning.
CLEANING VERTICAL SURFACES
IMPORTANT: Remember that the washer can deliver a high pressure spray that can break glass and gouge
soft wood and other materials.
When cleaning building interiors or exteriors without detergents, work from top to bottom. This will help
eliminate streaks. In interiors, start with the ceiling rst, then the walls and the oor last.
Clean around windows carefully. If glass panes are not well-caulked and puttied, the high pressure spray
could break the glass.
Never spray directly overhead. Always spray ahead
to avoid dripping or falling debris.
REMOVING PAINT
IMPORTANT: Remember that high pressure spray
can gouge soft woods and other
materials, as well as loosen grout.
1. Direct spray at a 45° angle about 4 to 12 inches (10
to 30 cm) from surface.
2. Spray in a back and forth motion, try to get beneath
the loose and bubbled paint.
3. Do not be concerned with the paint that remains. It should be sufciently bonded so as not to cause repainting
problems.
4. Some remaining paint may curl up at the edges. These edges should be scraped with a steel brush or scraper
just before painting.
CLEANING RADIATOR FINS
IMPORTANT: Some engine and radiator manufacturers
may not permit cleaning radiators with a
high pressure washer. See equipment
Operator’s Manual.
1. Use clean water without detergent.
IMPORTANT: Spray straight into the radiator to prevent
bending ns.
2. If possible, direct spray in the direction opposite to
normal air ow through the radiator.
PR-Series Operator’s Manual-E/F 21
Operating the Washer
DETERGENT USAGE GUIDE
CAUTION: Use detergents carefully. Read
labels thoroughly and follow all instructions
for preparation, use, safety, transportation and
disposal. Be prepared to tell a physician exactly
what detergents you are using in the event of an
emergency. Keep all detergents out of reach of
children.
Be aware that two detergents can be mixed
on the sprayed surface. In this regard, some
detergents may give off harmful fumes or start
an unpredictable chemical reaction when mixed
with another detergent.
NEVER SPRAY FLAMMABLE LIQUIDS such as
gasoline, fuel oil, alcohol, naptha, etc.
The washers are designed to dispense John Deere
approved cleaners and degreasers.
IMPORTANT: Using detergents other than John Deere
approved cleaners and degreasers is
NOT recommended.
If the use of detergents other than those approved by
John Deere is desired, be sure to read and follow all
detergent labels exactly regarding preparation, use,
safety, transportation, and disposal. Keep in mind that the
washer’s detergent system further dilutes the detergent
with water, and that some detergents may not be
concentrated enough to properly work with the system.
Some detergents may not give premix instructions and
may require experimenting to determine proper dilution
for your application.
