John Deere Operator's Manual 17
OPERATING INSTRUCTIONS
FLUSHING THE SYSTEM:
This unit has a steel coil which, after setting, will cause the water remaining in
the coil from the previous usage to turn brown or black. This water must be
flushed from the system before start-up. This procedure should be performed
without the high pressure hose, gun and dual lance assembly installed.
1. Turn on the water supply.
2. Move the switch to the "Pump" position. Low pressure water will begin
flowing from the water outlet. This allows the unit to flush any particles from
the system. The unit is flushed when the water is clear.
3. Once the system is flushed, move the switch to the "OFF" position and
connect the high pressure hose to the water outlet of the unit.
4. Connect the trigger gun and dual lance assembly to the high
pressure hose.
START-UP/COLD WATER OPERATION:
1. Refer to the "Safety Precautions" pgs. 4-7 before starting the unit.
2. Locate the Safety Decals on your unit and heed their warnings.
3. Ensure that the switch is in the "OFF" position.
4. Pointing the trigger gun in a safe direction, unlock the trigger gun and
squeeze the trigger. Brace yourself for possible gun kickback when the
pump starts.
5. Move the switch to the "Pump" position.
6. Once the unit has started, perform the following procedures with the gun
open:
a. Inspect for system water leaks, oil leaks and fuel leaks.
If a fuel leak is found, TURN UNIT OFF IMMEDIATELY! See "Risk of
Explosion or Fire", pg. 5. Be sure that all damaged parts are replaced
and that the mechanical problems are corrected prior to operation of
the unit. If you require service, contact Customer Service.
b. Inspect high pressure hoses for kinking, cuts and leaks.
If a cut or leak is found, DO NOT TOUCH HOSE AT LEAK!!! TURN UNIT
OFF IMMEDIATELY! Replace hose before starting the unit. See "Risk
of Injection or Severe Cutting Injury" pg. 6. Be sure that all damaged
parts are replaced and that the mechanical problems are corrected
prior to operation of the unit. If you require service, contact Customer
Service.
7. At this point, the unit is operating as a cold water pressure washer. Trigger
the gun several times and try adjusting the water pressure by rotating the
grip on the dual lance. NEVER place hand or fingers in front of the nozzle
or look directly into the nozzle! High pressure water creates a risk of severe
injury!
8. 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 packings, resulting in costly pump
repair.
NOTE: If this unit is equipped with an Auto Start/Stop feature, the pressure
washer will shutdown if the gun is not triggered after a designated
amount of time. The pressure washer will start again once the gun
is triggered. The Auto Start/Stop feature is preset at the factory for
shutdown at 90 seconds. It can be adjusted by an Authorized Service
Technician to shutdown from no usage after a minimum of 3 seconds
to a maximum of 5 minutes.
9. Your pressure washer can deliver high pressure spray and a variety of spray
patterns using cold water. If you wish to use the Hot Water, Steam application
or Cleaning with Detergents, see page 18 for the correct procedures.
CAUTION
RISK OF UNIT DAMAGE.
BE CERTAIN THE HOSE, GUN
& DUAL LANCE ASSY. ARE
NOT CONNECTED TO THE
UNIT WHILE FLUSHING THE
SYSTEM. FLUSHING ALLOWS
MINERAL DEPOSITS TO BE
RELEASED FROM THE SYSTEM
WHICH WOULD OBSTRUCT
OR DAMAGE THE GUN AND
NOZZLE ASSEMBLY RESULTING
IN COSTLY REPAIRS.
DO NOT ALLOW SPRAY PATTERN
TO REMAIN ON A FIXED AREA
FOR AN EXTENDED PERIOD OF
TIME. POSSIBLE DAMAGE MAY
OCCUR TO THE AREA.
WARNING
RISK OF INJECTION CAUSING
SEVERE INJURY!
-KEEP CLEAR OF NOZZLE! NEVER
PLACE HAND OR FINGERS IN
FRONT OF NOZZLE!
-DO NOT DIRECT DISCHARGE
STREAM AT PEOPLE OR PETS!
-AUTO START/STOP FEATURE
WILL SHUTDOWN THE PRES-
SURE WASHER UNTIL GUN IS
TRIGGERED. TO PREVENT
ACCIDENTAL HIGH PRESSURE
DISCHARGE, DO NOT LEAVE
