SET UP FOR OPERATION:
1. Install 100T taper bore nozzle or
100R ring nozzle. The SRNV100 is
not designed to operate with the
100TR taper ring nozzle. If using the
ring nozzle set, install desired ring size
in the ring nozzle cap. The ring nozzle
cap can be sufficiently tightened by
hand. NOTE: If the 100R is used, it is
supplied with the ring cap, part number
7872. If any other cap is used, the
nozzle al e will not completely close.
. To install the SRNV100, orient the
lower unit so the solenoid or hose
bracket will be located on the right
when viewed from the rear of the Big
Gun looking downstream.
3. Adjust location of stops to give desired
arc of coverage. Stops must be mounted
so that the arrows point toward each
other and the trip lever is located between
the arrows. If the stops are reversed on
the wrong end of the arc then the Big
Gun will fail to reverse.
4. The SRNV100 is factory set for normal
rotation speed. If a faster or slower
rotation speed is desired, move the arm
weight backward for faster operation
or forward for slower operation. The
SR100 low pressure drive vane kit,
part number 9857, is available to
enhance the drive when operating in
a nozzle range of .5-.65 100T and
pressure below 60 psi. NOTE: If the
SRNV100 is mounted on a tilted riser
of 10 degrees (or 17% slope) or more,
a 100CBK counter balance kit is
recommended to pre ent back-
sliding and impro e proper rotation
throughout the entire arc setting.

WARRANTY AND DISCLAIMER
Nelson Big Gun® Sprinklers are warranted or one year rom date o original sale to be ree o de ective materials and workmanship when used within the working
speci ications or which the product was designed and under normal use and service. The manu acturer assumes no responsibility or installation, is limited solely to
replacement or repair o de ective parts, and the manu acturer will not be liable or any crop or other consequential damages resulting rom any de ects or breach o
warranty. THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY AND
FITNESS FOR PARTICULAR PURPOSES AND OF ALL OTHER OBLIGATIONS OR LIABILITIES OF MANUFACTURER. No agent, employee or representative o the manu acturer
has authority to waive, alter or add to the provisions o the warranty, nor to make any representations or warranty not contained herein. This product may be covered
by one or more o the ollowing U.S. Patent Numbers 3,744,720 and 3,559,887 and other U.S. Patents pending or corresponding issued or pending oreign patents.
5. If installing the SRNV100E (with solenoid), connect the solenoid wires to the
proper voltage source. Energizing the solenoid with the proper voltage results
in the valve opening. If installing the SRNV100H hydraulically controlled
(without solenoid), connect the actuator feed hose to the appropriate control
pressure circuit. Application of hydraulic pressure (equal to or greater than
SRNV100 base water pressure) to the actuator causes the nozzle valve to
close. If actuator control pressure (line pressure) is approximately 0 psi or
below, low pressure SRNV closure kit, part number 99 4, is recommended to
provide reliable operation.
6. Be sure the entire control system is operating properly and that the hydraulic
fittings are securely installed. Failure to do so could prevent the nozzle valve
from closing, possibly causing personal injury or property damage. Observe
an entire opening-closing-opening cycle for proper operation.
WARNING!
1. Read operating instructions before operating sprinkler or making any
adjustments.
. Never make adjustments or perform service while sprinkler is in operation.
3. Stand clear of high velocity water stream.
4. Never direct water stream onto roadway or electrical transmission lines.
5. Stay clear of nozzle valve linkage during operation. High clamping forces exist.
6. Stand clear of sprinkler during operation. Abrupt water spray exists during
opening and closing of valve.
7. To avoid injury or damage, check for proper operation of control system
before using nozzle valve.

PROBLEM: Nozzle stopper (valve seat) continues to leak when closed.
SOLUTION: 1. Adjust valve seat to assu e even contact on nozzle seal su face.
a. Disconnect actuato pin .
b. Loosen the valve seat locking nut .
c. Rotate leve assembly to closed position and hold valve seat
lightly against nozzle seal su face. Adjust valve seat by otating the
stoppe in o out as equi ed to achieve full contact with the nozzle seal su face.
d. Tighten the locking nut .
2. Adjust linkage to assu e adequate closu e fo ce.
a. Adjust linkage assembly at A so that 12-15 pounds fo ce is equi ed to
push link B against closu e stop (disconnect and econnect lowe toggle
pin du ing adjustment as equi ed to check closu e).
b. Reconnect actuato pin .
PROBLEM: Nozzle stopper wont clear stream when open.
SOLUTION: Adjust actuato position to assu e complete opening.
