OPERATOR’S MANUAL 4

17. When the machine is working, do not cover or place
in a closed space where ventilation is insufficient.
ASSEMBLY
Upon arrival, inspect the shipping crate for damages. Un-
crate and examine all parts. Note any damage to machine
or components for claims against freight carrier.
Jets have antifreeze in the pump to protect it from freezing
conditions during shipment and storage. If machine will
be stored and operated in a cold climate, follow Freeze
Protection instructions on page 9.
PRE-OPERATION CHECK
❑
Pump oil (SAE 30W non-detergent oil)
❑
Cold clean fresh water supply (6 gpm • 5/8"
(15.875mm) • 20 psi)
❑
Hose, nozzle
❑
Water filter (intact, non-restrictive)
SET-UP PROCEDURES
These machines are meant to be used at or near the
working area and under operator supervision. If machine
must be located out of sight of operator, special controls
may be required for proper machine operation and opera-
tor safety.
Locate the equipment on a solid level area with slopes
for drainage. Avoid areas where water can be sprayed at
machine.
Before using the jet, make sure there are no impurities in
the incoming water supply. Turn the water source on for
at least 15 seconds, to remove any possible debris in the
water before connecting hose to water inlet swivel.
The inlet screen located inside the filter should be cleaned
before each use. To clean the inlet screen, unscrew cap
beneath the filter, remove the screen and rinse thoroughly
with water. Then replace screen.
Connect one end of a garden hose (not included) to
the water faucet — water supply not to exceed 100 psi
(6.9 Bar) and the other end to the water inlet of the jet
machine. (See component identification drawings on next
pages.) Use heavy duty 3/4" hose of no more than 50 ft.
(15m) in length. If run without an adequate water supply, the
pump will cavitate. Cavitation causes the pump to vibrate,
causing damage to the pump.
Note: Lack of water supply
can lead to seal damage, causing a loss of pressure and
will void the warranty to the pump.
Maximum temperature from the water source should not
exceed 140°F
(60°C) . Using water hotter than 140°F (60°C)
can cause damage to the pump and void the warranty. If
jet is being used to clear ice blockages, see instructions
on page 8.
Remove oil plug on top of pump and replace with dipstick
supplied.
Hose Selection Guide
Select the proper hose diameter for the line to be cleaned.
When using new hose, run water through it to clean it out
before attaching the nozzle.
Hose Size (ID)* Pipe Size Typical Applications
3/8" or 5/16" 4" to 8" Floor drains, septic lines, long
(9.925mm
(
102mm to 203mm)

or 7.938mm)

2" to 4" Kitchen sinks, laundry drains,
(6.35mm) (51mm to 102mm)

1/8"
1-1/2" to 2" Small lines, bathroom sinks,
(3.175mm) (38mm to 51mm)
tight bends
* Inside Diameter
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 example, at 2 GPM
(.13L/sec) a 1/4"
(6.350 mm) hose will lose 180 lbs. (12.4 bar) of pressure
over 100 ft. (30.5m) of hose, yet a 3/8" (9.925mm) hose
will only lose 25 lbs. (1.7 bar) of pressure over the same
length and at the same flow rate. At 4 GPM, a 3/8" hose
will lose 90 lbs.
(6.2 bar) of pressure over a 100 ft. (30.5m)
length. The gauge reflects pressure from the pump only,
not pressure at the end of the hose. 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.
Hoses of the same diameter may be coupled together using
a screw coupling, but it is not recommended for use in lines
smaller than 8"
(203mm) in diameter. The long length of
the hose connectors and coupling together can get caught
in bends in the line.
PART NUMBER ADAPTER SIZE (FPT)
8.705-364.0 1/4" x 1/4"
8.705-366.0 3/8" x 3/8"
8.705-369.0 1/2" x 1/2"
8.705-371.0 3/4" x 3/4"
Coupling two different size hoses can be done through the
spray wand trigger or foot pedal.
It is not advisable to have two different hose sizes coupled
in a drain line. There is a tremendous loss of pressure
when combined, aside from the difficulty of getting around
bends.
The 3/8"
(9.925 mm) and 1/4" (6.35mm) hoses may be
attached to the fitting in the core of the hose reel using the
swivel at one end of the hose. The 3/8" hose may also be
attached directly to the accessory outlet by using a twist
connect. The 1/4" and 1/8"
(3.175mm) hoses may be con-
nected directly to the accessory outlet if an adapter fitting
