(1) The gun has been designed for continuous use, at a water temperature of 60°C (140°F). It can resist at the max
temperature of 100°C (210°F) for short periods only, as, when the gun shuts off, the heater continues to transmit the heat
to the water, thus increasing both temperature and pressure up to high, dangerous values.
Using the gun at a water temperature higher than 60°C involves for the operator the use of adequate safety devices,
such as gloves, glasses, etc.

For a correct utilization, follow the directions of this manual
Re-print them on the Use and Maintenance booklet of the machine.

DIMENSIONAL DRAWING
INSTRUCTIONS
This product is to be utilized with clean fresh water, even slightly additivated with normal detergents. For use involving
different or corrosive liquids, contact the PA Technical department. Appropriate filtration should be installed when using
unclean liquids. Choose the gun in line with the data of nominal running (system rated pressure, max flow and max
temperature). In any case, the pressure of the machine should not exceed the permissible pressure rate imprinted on the
gun.
INSTALLATION
This gun was designed to operate with hot water (in compliance with the technical specs). Provide the plant generating
hot water with an equipment limiting the incidental increase of the fluid temperature.
Always fit a safety valve to protect the delivery conduct when the latter is under pressure.
Choose a suitable nozzle and ad just the valve mounted in the front of the gun, thus obtaining a constant supply and
avoiding unpleasant pressure spike when closing the system.
If the nozzle wears out, the pressure falls. When you install a new nozzle, adjust the system back to the original
pressure.
OPERATIONS
The gun opens and closes a high pressure conduct by means of a piston acting on a seat; the return is controlled by a
spring which releases the trigger: ATTENTION: this gun is equipped with a retarder closing device in order to limit
the pressure spikes on the pump and in particular conditions during the starting of the pump a pressure spout
may arise for a few seconds even with the gun closed. In order to prevent injuries or damage see illustrated
chart nr 10.9113.00 attached to the article.
WATER HOSE FEED
By high or very unsteady pressure values on delivery, it is necessary to mount a pressure reducer , both to level the flow
rate on delivery and to protect the system components.

REGULATIONS
The design and construction of our products comply with: norm CEI EN 60335-2-79 first edition, published in
1999-03 and its respective variations on the project norm prEN 1829.
Read this manual before starting the assembly.
For a correct utilization, follow the directions described in this manual and re-print them on the Use and maintenance
manual of the machine.
The present manual is valid for all the guns named RL 60.
SPARES
Use original PA spares only in order to get both a correct operation and a long lasting, reliable product.
MAINTENANCE
Maintenance has to be carried out by Specialized Technicians.
STANDARD: every 400 working hours (circa 10,000 cycles), check and lubricate the seals with water
resistant grease.
SPECIAL: every 800 working hours( circa 20,000 cycles), check the wear of the seals and internal parts and
if necessary, replace with original PA parts, taking care during installation to lubricate with water resistant
grease.
CAUTION: re-assemble the gun restoring the original conditions.
The manufacturer is not to be considered responsable for damage as a result from incorrect fitting
and maintenance.
Technical data, descriptions and illustrations are indicative and liable to modification without notice.
