Always set up your Viper at home and at least do a "dry run" to make
sure you understand the unit and have all parts needed. Connect the pump
and at least pretend you are running. This will ensure you have all the
Note....There are pictures below.
Tips from Doc on running the Viper. (Read them as they will really help.)
Transporting... I leave my header box and first tray assembled. Put
the wood block in-between the two and load in my truck. Then, I put the
lower / last tray upside down on TOP of the header box. MAKE SURE you
use a bungee to hold it down or it will go flying down the highway. Then
I put the legs and mat inside the unit. This gives me plenty of room in
the truck bed.
Try to always set up the Viper on a slight downhill area. This will
avoid the header box angle being so high. The flatter the ground the
higher you have to raise the header box. Also, you can stand above the
header box and not have to reach so high.
Install the TOP of the mat first or keep the mat TILTED a little
when sliding up or down. It fits tight. Make sure the side tape is up on
all sides. Then put in blue Hog Moss, then the connection bar through
DON'T lose the small black rubber fitting that comes with your spray
bar. They are hard to replace and not cheap. A stupid piece of rubber I
ALWAYS start the unit very low to the ground. Put the top of
the sluice about 12" off the ground and the exiting end about 3". The
biggest mistake I see people make is to start it off high. Keep it
Buy a level and a DIGITAL angle indicator.
LIKE THIS ONE It will allow you to check the pitch of the sluice and
level. Set your sluice about 8 degrees on the pitch.
Header box. Set your header box so that MOST of the rocks pass over
the grizzly with ease. Once in a while you will have a clay ball or
large flat rock hang up, but that is normal.
If you are running the Champion pump we recommend, DON'T be afraid
of the water. I have been running the water stronger and stronger. I'm
now running about 60% of throttle. WATER IS GOOD...
Adjust your sprayer ends. I like mine to hit about 10 - 12 inches
before the end of the box. Make SURE they are equal and even.
I like to run my slurry smooth and even. if bucket feeding, trickle
dirt at a steady pace rather than dumping. You'll see the water run
smooth like a milkshake.
After shut down, loosen reverse riffle slightly. Allow water to
gently drain out.
Put a tub under the end of the sluice. Pull mat gently (give a
slight twist if needed to release one side) then roll into the tub. Fill
tub with water rinse mat. REVERSE roll the mat. (GROOVES ON THE
OUTSIDE). Dip and rinse. Now reverse roll the other way, do the same.
IMPORTANT... SAVE ALL YOUR CONS. There will be gold you can not see
with the human eye. Don't pan in the field and discard cons.
Two longer bolts hold the grizzly bars in place with the
the square metal tube.
Header box "legs" / tabs go inside the lower tray box.
Use lock washers here.
Always keep nuts and wing nuts on the outside so they
with the mat going in and out.
Rubber gasket holds spray bar firmly in place.
Don't fully tighten leg brackets until you get pitch right
sluice. Then get legs perpendicular to the ground and tighten.
Always tighten both brackets before running. Header box
get very heavy.
Safety tube should be left in place at all times. Both
and transporting. Keeps metal from hitting metal.
Mat goes in first. Then the Hog Moss. Secure with hold
Then insert reverse riffle.
