1. OVERVIEW
This manual is prepared to provide the operator with the basic information
needed to operate the Ripsaw™ Rotating Hydro-Excavation nozzle. The
operating recommendations in the manual will ensure that you receive
satisfactory nozzle performance. All operating personnel responsible for the
care of this equipment should be familiar with the information in this manual.
If you have any questions or problems with this equipment, please contact the
distributor you obtained the product from.
RIPSAW™ ROTATING HYDRO-EXCAVATION NOZZLE
INSTRUCTIONAL SHEET
REV C
• Always wear the proper PPE (Personal Protective Equipment) when using
these nozzles.
• Do not point nozzles at people or animals. Serious injury can result from
high-pressure water from these nozzles.
• Nozzles are recommended for use with high-pressure spray wand with
automatic shut off (Dead man’s switch).
• Always observe proper grounding procedures when performing hydro-
excavation.
• Urethane coating on the nozzle tip is designed for safety. Replace nozzle
when urethane coating is worn.
• A distance of at least 8” must be maintained between the nozzle tip and
the underground facility and/or subsoil. The nozzle should never be
inserted into the soil.
• The wand/nozzle shall never remain motionless during excavation.
Aiming directly at the underground utilities should be avoided at all times.
• Observe the referenced industry best practices for recommended
maximum pressures for rotating nozzles within 18” of utilities. Within 18”
of utilities the operator should lower water inlet pressure from normal
operating pressure to a maximum of 1500PSI and use the nozzle to “wash
down” the utility, not to blast.
• Static nozzles are not to be used within 18” of utilities.
• Be sure pump is shut off and disconnected prior to performing
maintenance or replacing this nozzle.
• This nozzle is not intended for chemical application. Running chemicals
through the nozzle may reduce the life of the nozzle.
• Select the nozzle size based on intended application and performance.
• Follow all applicable national, state, and local safety regulations.

5. TROUBLE SHOOTING
My nozzle stream is failing to rotate
(Lasering).Water is going around the nozzle
and not through it (blow-by).
Check your pressure. Pressure for this nozzle should be set at a minimum of 1,000 PSI at nozzle. (3,200 PSI Max.)
Check inlet screen for debris. Clean and/or replace.
Nozzle may fail to rotate based on normal wear and tear, it may be time to rebuild. Refer to our repair kit.
No ow, low ow, or not enough
impingement.
Increase your pump pressure. (Pump must remain between 1,000 PSI (min) and 3,200 PSI (max). Check for
desired result.
Change nozzle to a larger nozzle size (higher ow rate). Check for desired result.
