—Read the safety and operating instructions before using any Spartan Tool products. Drain and sewer cleaning can
be dangerous if proper procedures are not followed and appropriate safety gear is not utilized. Read the engine
owners manual for instruction and safety precautions on engine operation.
—Gasoline is extremely flammable and is explosive under certain conditions.
§Refuel in a well ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the
area where the engine is refueled or where gasoline is stored.
§Do not overfill the fuel tank (there should be no fuel in the filler neck).After refueling, make sure the tank
cap is closed properly and securely.
—Before starting unit, be sure to wear personal protective equipment such as safety goggles or face shield and
protective clothing such as gloves, coveralls or raincoat, rubber boots with metatarsal guards, and hearing protection.
—Carbon monoxide exhaust and/or gasoline fumes from this equipment can create a hazardous atmosphere in
confined spaces (which may include, but are not limited to, manholes and septic tanks), closed garages or other areas
which may not be properly ventilated. In particular, excess gasoline fumes can create an explosion hazard. Such
hazardous atmospheres can cause death or severe injury. Do not operate this equipment in any confined space or
area with inadequate ventilation. Operate this equipment only when located outdoors or in an open, well ventilated
area.
—Insure the jet hose has been placed in the pipe (minimum of 6 feet suggested) before engaging the water pressure
to prevent the hose from coming out of the pipe prematurely and causing injury.
—Always shut the water pressure off before pulling the hose out of the pipe. Mark the hose a minimum of 6 feet
from the end to help insure the hose is not accidentally pulled out of the pipe while still under pressure. Shut off the
water pressure when the hose mark is encountered. WARNING: Portions of the system can still be under pressure
even if the unit is not operating.
—Never point the wash gun at anyone while operating the unit. Injury may result.
—Drains and sewer can carry bacteria and other infectious micro-organisms or materials which can cause death or
severe illness.Avoid exposing eyes, nose, mouth, ears, hands and cuts and abrasions to waste water or other potentially

Jet Applications Areas
There are a wide variety of uses for the Spartan Model 758 Water Jet. Here are just a few:
—Apartments/Hotels
Mains and garage drains, remove all grease and debris from main lines under the buildings.
—Factories
Food processing plants and foundries have frequent drain and sewer blockages. Set up preventive maintenance
contracts to avoid risk of total plant shutdown.
—Farms, Rural
Clean and spray barns, pens and heavy farm equipment, revitalize drain field in septic systems and field tile.
Clear blockages in liquid manure system.
—Housing Authorities
Any drains, laundry lines, garbage chutes, clean-outs and many grease-removing applications.
—Institutions
Clean-running drains and sewer lines are a “must” in hospitals, schools, prisons. Use in kitchens, remove lime
deposits on buildings and clean parking lot drains.
—Municipals
Open culverts for proper flood control, wash down manholes, clean lines in wastewater treatment plants.
—Residential
Clean drain lines, septic lines, field tiles, culverts, swimming pools, surface cleaning and sandblasting.
—Restaurants
Grease in drains is always a problem - Your Spartan Water Jet actually removes grease from the lines instead
of simply punching a hole through the blockage, risking reaccumulation downstream.

Uncrating and Prep
4.) Next you’ll want to plan out the exhaust routing and the
frame mounting points. If required, use the flexible exhaust
pipe (cut to length) and elbow supplied with this unit. Be
sure to avoid any brake and fuel lines, fuel tank, spare tire
mounts, etc. Once the desired position is achieved, mark
the hole locations for the exhaust port and the frame mounts.
(See Fig. 1)
5.) Using the skid mount frame holes as a guide, drill (8)
13/32 diameter holes through the floor of the vehicle.
6.) Place the (8) rubber pads between the frame and the
vehicle floor and then secure the skid mount unit to the vehicle
using the (8) 3/8-16 x 3” screws, (16) 3/8 flat washers, and
(8) 3/8-16 locking nuts.
7.) Cut or drill an opening in the vehicle floor and mount the
exhaust port. Use the supplied muffler clamps to secure the
flexible pipe and elbow to the muffler.
8.) Remove the battery cover and connect the positive cable
(red) to the positive post of the battery. Replace cover.
9.) Connect the fill hose and bypass hose to the water tank.
No clamps required (See Fig. 2)
10.) Connect the water tank to the pump using the supply
hose (short hose included with unit) and (2) hose clamps
(included with unit) (See Fig. 3 on next page)
11.) Connect the low water switch. (See Fig. 4 on next
page)

If you received your machine crated, follow the steps below.
1.) Remove the 8 bolts that secure the jetter frame and the water tank frame to the crate.
2.) Position the unit inside your van or truck bed in a location that best fits your application.
3.) Secure the two units together by using the included (2) 3/8-16 x 4-1/2” screws, (4) 3/8 flat washers,
and (2) 3/8-16 locking nuts.

Pump and Pressure System
The pump and relief valve are the heart of your jet. They have been specially designed for use with water
(temperatures up to 140°F ) for pipe jetting, but can provide useful water flow for many other cleaning
jobs using the optional wash down gun and special attachments. The positive displacement pump (each
crankshaft revolution has to move a certain amount of water) uses 3 plungers (similar to pistons in an
engine) to create water flow. Pressure is not created until the pump outlet is restricted with a valve or
nozzle. The pump, valving and hoses can support pressures to 3000 psi.
The regulator valve acts to direct the water flow to the water tank when the hose reel and gun valves are
off or if nozzles provide too much restriction for total flow.Always use clean water to keep the regulator
valve operating properly. The hose and nozzle are designed to allow full flow at 3000 psi (at 3200
engine rpm) and the wash down gun operates at 1600 PSI max pressure. If leaks develop in the system
between the relief valve and hose reel valve (or gun valve) you will hear intermittent engine surges in
bypass as the bypass pressure gradually drops and is built up again by the pump. Tighten or otherwise
repair the leaks for smooth running.Always stop engine and release pressure before any plumbing changes
or repairs.
Because of the inherent hazards with high pressure, use only Spartan high pressure hoses and components
when repairing your machine.
If the nozzles become worn or if the gun is used with the jet hose, the regulator valve allows the same total
flow but at lower pressure because the restriction is lower. To maintain desired PSI - replace nozzles.
If nozzles become plugged, the regulator valve will direct some of the flow back to the water tank while
providing pressures over 3000 psi. If these pressures are seen with normal engine speed (3200 rpm),
check and clean the nozzles. When using optional lengths of 1/4” hose the operating pressure can also be
over 3000 psi at full gpm. Reducing engines rpm will produce lower pressures to prevent regulator valve
from bypassing off and on. Continued operation at pressures over 3000 psi can cause engine overheat
and reduce engine life.

High Pressure Water Jetting
High pressure water jetting is the utilization of high pressure water combined with sufficient water flow to remove
debris in drain/sewer pipes. High pressure water alone cannot do the job. You need proper flow to wash the debris
downstream where it can be collected and removed. High pressure water jetting can also be used to remove debris
on surfaces.
A high pressure water jet consists of a pump, a motor or engine, a hose reel, a given length of hose and a
various assortment of nozzles.
A pipe is cleaned with a high pressure water jet by directing water pressure and flow through a nozzle.
Controlled water pressure and flow propels a water jet through the sewer pipe allowing it to remove and wash
away the obstruction. (See Fig. 3. below)
Ideally, a sewer pipe is cleaned from the lower end of the pipe and the hose propels itself to the higher end of
the pipe. By slowly withdrawing the jet hose, the water pressure and flow cleans the line most effectively.
How AJet Works
(Penetrating Nozzle) 75800900
Nozzle to be used for initial penetration
of sewer pipe.
(Closed Nozzle) 75800800
Nozzle to be used for thorough cleaning
of sewer pipe.

Water Tank Filling
Fill the water tank from a clean water source. Always flush rust out of hydrants before connecting fill hose (with
garden hose fitting) to top fill valve. Your water supply hose may remain connected for further filling by controlling
water flow at fill valve.
Important Note: (If the next 4 items are not followed, cavitation of the pump could occur and reduce operating
efficiency and severely damage the pump.)
—Use water temperatures under 140°F.
—Ensure that water strainer is clean (check daily or as needed).
—Make sure the strainer valve (between the tank and the pump) is fully open during operations. This valve
stops tank flow to allow strainer service.
—The pump drain valve must be closed. It must not drip when engine is off and strainer valve is open.
