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 orifice’s causing a spike in the high
pressure system which will rupture the burst discs
and could cause damage to components.
