5.
Never run pump without water in it.
Operating the machine
without water will cause the pump to fail and void the warranty.
6.
Check for worn hose and components before each use.
Check that all fittings are secured before using jet.
Worn or
lose fittings can cause damage to the machine and injure the op-
erator.
7.
Protect machine and pump from freezing.
Storing or operating
the jet in temperatures below freezing can damage pump, hose
and other jet components. Store unit indoors or protect with anti-
freeze when not in use.
8.
Do not sit or stand on carrying case
.
9.
General Wire Spring Co. will not be liable for any changes
made to our standard machines or any components not pur-
chased from General Wire Spring Co.
AUTOMATIC UNLOADER
The JM-1000 Mini Jet is equipped with an Automatic Unloader to pro-
tect the pump. It prevents pressure overload in the event that the noz-
zle is clogged or spray wand trigger is off. A water sensor in the pump
will "sense" if the water is flowing and automatically turn off the power
off if the water stops flowing to protect the pump from damage. The
unit may shut off for 1 - 2 seconds while in operation to allow water to
prime the pump. Do not run the jet for more than 5 minutes with the
pump in bypass mode. Continuing to operate in bypass mode for ex-
tended periods will cause damage to the pump. Excessive tempera-
tures will damage the pump and void the warranty.

JET NOZZLES
1. A variety of jet nozzles are available for drain cleaning. Each has a
different spray pattern and purpose. Some nozzles may have an
orifice in the front to cut through the stoppage. All will have holes
in the back to drive the hose down the line and clean the walls of
the pipe. A tight spray pattern (15°) has more driving power for
long runs, a wide spray pattern (30°) does a better job of cutting
the grease off of the walls of the pipe. A combination of nozzles
may be required to clear a line. Always turn off the machine and
turn off output valve before changing nozzles.
2. Make sure the nozzle you are using matches the pump size. A
3000 psi pump requires a different nozzle orifice than a 1500 psi
pump. Mismatching nozzles with pump size will either cause too
little pressure, which may not clear the drain, or too much pres-
sure, which may damage the machine.
3. Check nozzles before and after each use for clogged holes which
can cause pressure to increase to dangerously high levels and
damage the pump. A clogged hole can be cleared by simply using
the NCT Nozzle Cleaning Tool.
4. Use the nozzle selection guide to determine what nozzle you will
need for various applications.
JET HOSE
When selecting hose size, consider that pressure is lost as the
water travels down the length of the hose. As the length increases, the
pressure decreases. In addition, the smaller the diameter of the
hose, the greater the loss of pressure per foot will be. As an exam-
ple, a 2 GPM a 1/4” hose will lose 180 lbs. of pressure over 100 ft. of
hose, yet a 3/8” hose will only lose 25 lbs. of pressure over the
same length and at the same flow rate. It is important to select the
largest possible hose size in order to have as much pressure as
possible at the end of the hose.
