Stripe Hog Systems
THE HIGH PRESSURE STREAM FROM THE SPRAY NOZZLES
CAN CAUSE SEVERE INJURY OR DEATH IF IT COMES
IN CONTACT WITH HANDS, FEET OR ANY PART OF A
PERSON’S BODY. IT CAN ALSO PROJECT LOOSE DEBRIS
IN THE AREA OF THE HOG HEAD WITH ENOUGH FORCE TO
CAUSE SERIOUS INJURY, PARTICULARLY TO THE EYES.
HIGH PRESSURE WATER CAN TEAR OFF SKIN AND INJECT
WATER DIRECTLY INTO THE BLOOD STREAM WHICH CAN
BE FATAL. ALWAYS DEACTIVATE THE HIGH PRESSURE
SYSTEM BEFORE RAISING THE HOG HEAD AND MAKE SURE
THE AREA IS CLEAR OF PEOPLE, HANDS AND FEET BEFORE
ENGAGING THE PTO AND 40K PSI SWITCH FOR THE HIGH
PRESSURE SYSTEM TO TEST AND INSPECT THE NOZZLES
WITH THE HOG HEAD RAISED.
If a nozzle rates as a 5 or higher on the Nozzle
Quality Chart it is worn or damaged and must be
replaced. Nozzles are easy and quick to replace.
Refer to the nozzle replacement procedure in the
Maintenance section of this manual for detailed
instructions for replacing nozzles.
Nozzles typically last 12-16 hours of blast time,
however, you can experience shorter or longer
nozzle life, depending on the source and quality of
water being used. Any dirt or debris in the system
can clog nozzle orice’s causing a spike in the high
pressure system which will rupture the burst discs
and could cause damage to components.
NOTICE:
NOZZLES MUST ALWAYS BE CHECKED WITH SPRAY
BAR PROTECTORS REMOVED TO AVOID INACCURATE
READINGS. START THE PUMP AT LOW PRESSURE AND
SLOWLY INCREASE TO OPERATING PRESSURE TO CHECK
NOZZLE QUALITY AS WELL AS LEAKS ON THE SPRAY BAR,
NOZZLES AND HOSES. DISENGAGE THE PUMP AND RETURN
ENGINE TO IDLE TO RELIEVE ALL PRESSURE BEFORE
MAKING ANY REQUIRED REPAIRS OR ADJUSTMENTS. TO
INCREASE THE LIFE EXPECTANCY OF THE SPRAY BARS
AND NOZZLES, ALWAYS REMEMBER TO INSTALL THE
SPRAY BAR PROTECTORS BEFORE BEGINNING BLASTING
OPERATIONS.
