Preparing the Washer
filling fuel tank
CAUTION: Risk of fire. 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 muffler.
-Fill fuel tank outdoors away from flames and open sparks.
-Do not smoke when filling fuel tank.
-Do not overfill fuel tank. (There should be no fuel in filler 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 TY15977 gasoline stabilizer is highly
recommended . 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 |
|
|
filler cap (A) and place cap in a clean area away from |
|
|
muffler. |
|
2. |
Slowly fill the fuel tank to bottom of filler neck with lead |
|
|
free gasoline. Do not overfill, leave approximately 5mm |
|
|

Preparing the Washer
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 flattening of the supply hose.
2.Inlet water flow must be at least 125% of pump rated flow (see table below). Check volume by timing how long it takes to fill a 5 gallon (19 L) container. For example, a flow rate of 3.0 GPM would fill 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 flow 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 flow is at least 125% of pump rated flow (see table below). In static draw situations, water flow 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 flow rates. Check for adequate water flow rate each time an extension is added. Water flow rates can be increased by using the largest possible internal diameter supply hose.
IMPORTANT: Inlet water temperature must not be more than 125° F (60° C). Damage to the pump may result.

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.
8" - 10"
(20-25 cm)
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 first, then the walls and the floor 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 sufficiently 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 fins.
2.If possible, direct spray in the direction opposite to normal air flow through the radiator.

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.
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.

Operating the Washer
cLEANING WITH detergents
CAUTION: Wear goggles, respirator, and protective clothing
to help prevent injury from detergents and spray.
IMPORTANT: DO NOT direct pressure washer spray at the washer.
1.Mix detergent as instructed by the manufacturer.
2.Be sure that water supply is adequate and turned on fully.
3. Insert detergent strainer into solution (A). Be sure that hose is clear and fully submerged in solution.
IMPORTANT: The detergent system will work only if the detergent nozzle is installed.
4. |
Install detergent nozzle (B). (Black nozzle with brass body.) |
|
5. |
Start washer and squeeze gun trigger. If detergent does not spray |
|
|
within one minute, check to make sure the detergent hose is in the |
|
|
solution and is not plugged. |
|
6. |
To help avoid streaking, apply detergent to the lowest surface first, |
|
|
and move up, using long overlapping strokes. Allow solution to |
|
|
soak for several minutes. |
|
IMPORTANT: Remember that high pressure spray can gouge soft |
A |
|
|
woods, damage other materials and loosen grout. |
|
7.Install a pressure nozzle. With the nozzle approximately 6 to 10 inches (15 to 25 cm) and at an angle to the surface, power rinse the area from the top down.
8.If surface is not clean, repeat the above procedures.
IMPORTANT: To avoid damage and contamination with other detergents, siphon a gallon (3.78 L) of clear water through the system after each use.
shutdown
IMPORTANT: Shutdown procedures should be followed at the end of each cleaning operation.
1.If a detergent was used, place detergent inlet strainer in CLEAN water and operate trigger to spray water for a period of three minutes. This will flush the system of detergents and help prevent the detergent valve from sticking or corrosion.
2.Run engine at idle for 2-3 minutes.
3.Turn engine off by moving throttle lever (A) down to “STOP”.
