8. Never make adjustments on machine while it is in
operation.
9. Do not operate valve in the off position for extensive
periods of time as this may cause damage to the
pump.
10. The best insurance against an accident is precaution
and knowledge of the machine.
11. Shark will not be liable for any changes made to
our standard machines, or any components not
purchased from Shark.
12. Read engine safety instructions provided.
WARNING: Keep water spray
away from electric wiring or fatal
electric shock may result.
13. Never run pump dry.
14. Do not allow children to operate
the Shark
®
Jetter at any time.
15. Inlet water supply must be cold
and clean fresh water.
ASSEMBLY
Upon arrival, inspect the shipping crate for damages.
Uncrate and examine all parts. Note any damage to ma-
chine or components for claims against freight carrier.
The tires on the jets may be partially deflated for packing
and shipment. Reinflate tires to the pressure specified
on the side of the tire before using the machine.
Jets have antifreeze in the pump to protect it from freez-
ing conditions during shipment and storage. If machine
will be stored and operated in a cold climate, follow
Freeze Protection instructions on page 11.
PRE-OPERATION CHECK

Pump oil (SAE 30W non-detergent oil, General)

Cold clean fresh water supply (6 gpm • 3/4"
(15.875mm) • 20 psi)

Hose, nozzle

Fuel (unleaded 86 or higher octane)

Engine oil (SAE 10W40)
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 the operator, special
controls may be required for proper machine operation
and operator 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 sup-
ply, 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 10.
Remove oil plug on top of pump and replace with dipstick
supplied. Fill engine with oil. Refer to engine manual for
quantity.
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
(9.925mm (102mm to 203mm)
long runs
or 7.938mm)
1/4"
2" to 4" Kitchen sinks, laundry
(6.35mm) (51mm to 102mm)
drains, clean outs
1/8" 1-1/2" to 2" Small lines, bathroom
(3.175mm) (38mm to 51mm)
sinks, 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" (6.350mm) 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
