FILLING FUEL TANK
CAUTION: Risk of re. Handle fuel carefully.
-Do not add fuel when product is operating. Stop engine and allow engine to cool for two minutes before refueling. Hot surfaces can cause burns
and ignite spilled fuel. Do not touch mufer.
-Fill fuel tank outdoors away from ames and
open sparks.
-Do not smoke when lling fuel tank.
-Do not overll fuel tank. (There should be no fuel in ller neck.)
-Avoid spilling fuel. Wipe clean after refueling.
-Move from refueling area before starting.
-Prevent fires by keeping engine clean of accumulation, grease, trash and debris.
IMPORTANT: Do not permit dirt or other foreign matter
to enter the fuel system. This will cause hard starting, poor performance and engine damage. Always use clean fuel storage containers and funnels.
Use clean, fresh, lead-free gasoline. Do not use stale gasoline or gasoline that has been stored for a long time. Stale gasoline does not vaporize properly, causing hard starts. Use of leaded gasoline or gasohol is NOT recommended.
IMPORTANT: Do not mix oil with gasoline.
1. Wipe dust and dirt from around fuel tank. Remove
ller cap (A) and place cap in a clean area away from mufer.
2. Slowly ll the fuel tank to bottom of ller neck with lead free gasoline. Do not overll, leave approximately 5mm
(0.19 in.) of open space at the top of the tank for fuel expansion.

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.

(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.
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 sufciently 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.

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.
If you are not familiar with the detergent, always test a small area of the surface to be cleaned for adverse reaction. Do this a day in advance. Thoroughly rinse area with water.
