Nozzle Maintenance - Snapper 580.752640 Manual Del Operador

Check High Pressure Hose
High pressure hoses can develop leaks from wear, kinking,
or abuse. Inspect hose before each use. Check for cuts,
leaks, abrasions, bulging of cover, or damage or movement
of couplings. If any of these conditions exist, replace hose
immediately.
WARNING: The high pressure stream of water that this
equipment produces can cut through skin and
its underlying tissues, leading to serious injury
and possible amputation.
• NEVER repair high pressure hose. Replace it.
• Replacement hose rating MUST exceed maximum pressure
rating of unit.
Check Detergent Siphoning Hoses/Cleaning Tank
Examine the cleaning tank and detergent siphoning hoses
and clean if clogged. The hose should fit tightly on the
barbed fitting of the pump and detergent shut-off valve.
Examine the hoses for leaks or tears. Replace the tank or
hoses if either is damaged.
Check Spray Gun
Examine the hose connection to the spray gun and make
sure it is secure. Test the trigger by pressing the red button
and making sure the trigger "springs back" into place when
you release it. You should not be able to press the trigger
without pressing the red button. Replace spray gun
immediately if it fails any of these tests.

Nozzle Maintenance

A pulsing sensation felt while squeezing the spray gun trigger
may be caused by excessive pump pressure. The principal
cause of excessive pump pressure is a nozzle clogged or
restricted with foreign materials, such as dirt, etc. To correct
the problem, immediately clean the nozzle following these
instructions:
1. Shut off engine and turn off water supply.
2. ALWAYS point spray gun in a safe direction, press red
button and squeeze spray gun trigger to release retained
high water pressure.
WARNING: The high pressure stream of water that this
equipment produces can cut through skin and
its underlying tissues, leading to serious injury
and possible amputation.
Spray gun traps high water pressure, even when engine is
stopped and water is disconnected, which can cause
injury.
• Keep high pressure hose connected to pump and spray gun
while system is pressurized.
• ALWAYS point spray gun in safe direction, press red button
and squeeze spray gun trigger to release high pressure, every
time you stop engine.
3. Disconnect PrecisionSpray™ Selector from spray gun.
4. Use a small paper clip to free any foreign material
clogging or restricting the high pressure nozzles (A).

5. Using a garden hose, remove additional debris by back
flushing water through PrecisionSpray™ Selector. Back

Check that high pressure hose is connected to spray gun
and pump. Turn on water.
