OM-SR100-9 PN03083 2/18
NOTE ON LUBRICATION:
The Big Gun
®
sprinkler
is lifetime lubricated and does not require periodic
lubrication. The ball bearings in the H.D. lower bearing
operate in a water resistant lubricant that is packed in
the housing cavities and retained by seals. If repair of
the lower bearing is done, it is recommended to use
Nelson #6143 lubricant or a good grade of water
resistant lubricant such as Lubriplate 130-AA.
BE CAREFUL:
Read operating instructions before
operating sprinkler or making any adjustments. Never
make adjustments or perform service while sprinkler is
in operation. Stand clear of operating sprinkler. Stand
clear of high velocity water stream. Never direct water
stream onto roadway or electrical transmission lines.
WARRANTY AND DISCLAIMER
Nelson Big Gun

Sprinklers are warranted for one year from date
of original sale to be free of defective materials and workmanship
when used within the working specifications for which the product was
designed and under normal use and service. The manufacturer assumes
no responsibility for installation, is limited solely to replacement or repair
of defective parts, and the manufacturer will not be liable for any crop
or other consequential damages resulting from any defects or breach
of 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 of the manufacturer has authority
to waive, alter or add to the provision of the warranty, nor to make any
representations or warranty not contained herein.
SET UP FOR OPERATION:
1. Install nozzle. If using ring nozzle set, install desired
ring size in ring nozzle cap. The ring nozzle cap
can be sufficiently tightened by hand.
If using the
100 DN
ring nozzle,
correct orientation
is important. For reliable sprinkler operation, be sure
to orient the ring with the correct side out and the
“up” at the top of the nozzle. Incorrect orientation
can result in failure of sprinkler to drive.
2. Adjust location of reverse stops to give desired arc
of coverage. Stops must be mounted so that arrows
point toward each other and the trip lever is located
between arrows. If the stops are set incorrectly on
the wrong end of the arc, the sprinkler will fail to
reverse.
3. The SR100 is factory set for normal rotation speed.
If a faster or slower speed is desired, move arm
weight backward for faster operation or forward
for slower operation.
