Operating the Washer

PRIMING THE PUMP

1.It is essential to prime the pump on initial start-up and each time the water supply is disconnected from the unit after initial use.

2.Lay the high pressure hose out to remove any loops. Water flow will constrict the hose, creating tight loops if the hose is not straight.

3.Securely connect the gun assembly to the high pressure hose.

NOTE: The nozzle assembly should NOT be connected to the gun assembly at this time. See "Nozzle Connection" .

4.With the trigger gun locked in the "OFF" position, turn the water supply completely on. Pointing the gun in a safe direction, unlock the trigger gun and squeeze the trigger.

5.Low pressure water will begin flowing from the hose/gun assembly. This allows the unit to prime and purge any air from the system. The unit is primed when water flow is uninterrupted by air.

6.Once the unit is primed, release the trigger and lock the gun in the "OFF" position. Securely connect the nozzle assy. (See "Nozzle Connection")

If you require service, contact your John Deere dealer.

c.Inspect electrical cord for cuts. If a cut is found, DO NOT TOUCH OR USE ELECTRICAL CORD! Replace cord before starting the unit.

8.Trigger the gun several times and try adjusting the spray pattern. Be certain toLOCKthetriggerguninthe"OFF"positionwhenevermovingtheadjustable nozzle. NEVER look directly into the nozzle! High pressure water creates a risk of severe injury!

9.Do not allow unit to operate in bypass mode (with trigger closed) for more than three minutes without triggering the gun. Failure to follow this simple rule can cause premature failure of pump packing seals, resulting in costly pump repair.

10.Because your pressure washer delivers a high pressure spray and a variety of spray patterns, there are many cleaning jobs that can be done without the use of detergents. If a cleaning agent is required, see "Cleaning With Detergents" for the correct procedures.

Operating the Washer

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 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.
