— Read the safety and operating instructions before using any Spartan Tool product. Drain and sewer cleaning can
be dangerous if proper procedures are not followed and appropriate safety gear is not utilized. Read the engine
owner’s 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
infectious materials during drain and sewer cleaning operations. To further help protect against exposure to infectious
materials, wash hands, arms and other areas of the body, as needed, with hot, soapy water and, if necessary, flush
mucous membranes with water. Also, disinfect potentially contaminated equipment by washing such surfaces with a
hot soapy wash using a strong detergent.

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
If you received your machine crated, position crate so that your truck can be backed up to “front” side.
Now remove end of crate marked “front”. Remove hitch assembly from under machine. Connect and
tape wire plugs and attach hitch to frame with bowmalloy bolts provided. These bolts must be torqued to
74 ft.-lbs. (see Fig. 1). It is the uncraters responsibility to torque the hitch. Support the hitch and
remove vertical supports under frame. Hook up jet to truck and pull from crate. Remove packing materials
from jet. Door and engine keys are packed in a bag in the toolbox. Remove the contents.
If you receive your machine uncrated.
Upon receiving your machine double check the torque of all 7 hitch bolts. (See Fig. 1.)
Battery
Prior to shipping, the battery cables are disconnected from the terminals of the battery. The battery cables
will need to be reconnected to the battery before operating.

Before hitching and towing on public roads, check that the tow vehicle uses a 2” ball on a hitch rated class
II minimum, make sure keeper engages ball to secure hitch. Adjust if necessary.
Because of the inherent water tank sloshing when towing, pull your jet empty at all times.
The following 2 rules may limit your vehicles towing capacity and the tank fill level when towed.
Determine towing capacity as described below and follow guidelines in using the lowest value from
the 2 rules.
Trailer Hitch
— Check rating of vehicles trailer hitch -
WARNING: Class 1 hitches often uses 1 7/8 ball which is unsafe to couple with a 2" hitch.
Class 2 - 3,500 lbs. Towing capacity is required.
Vehicle GCWR (Gross Combined Weight Rating)
— Towing capacity = GCWR minus vehicle weight minus cargo weight minus passenger weight.
NOTE: GCWR is provided on your vehicle or in vehicle manual.
Vehicle Towing Capacity
— Refer to your vehicle owners manual for listed trailer towing capacity.
— Trailer towing capacity should equal GCWR (gross combined weight rating) minus vehicle weight,
cargo weight, people weight and (vehicle) fluids weight.
— Check axle load rotatings.
Towing Instructions
Wire the plug receptacle to your vehicle as shown below. Note: The wire colors used on the jet running lights are also
indicated in Fig. 2 for re-wiring to a different plug design.
—Always use safety chains.
—Always use trailer lights.
Fig. 2
The hitch jack should always be tilted up when towing to avoid damage to the caster wheel. Pin jack clamp securely.

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
downsstream 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.)
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.
When it is impossible to clean from the lower end of the pipe, the pipe must be water jetted several times to
remove all the debris. A skilled operator can effectively clean a drain/sewer regardless of the obstacles in his
way.

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.

prevent the engine from starting at low water levels.
— Check fuel level.
Note: Also Check engine and pump oil levels per manufacturer specifications (attached).
— Turn high pressure reel supply valve “off”.
— Hold in red relay button and key start the engine. Choke as necessary.
— Allow the engine to warm up at idle for 3 to 5 minutes before putting engine under load.
Engine Shut-Down
— Turn high pressure reel supply valve “off”.
— Allow engine to idle for 1 to 2 minutes
— Turn the engine key switch OFF. (The engine key switch must be OFF when the engine is not running to
avoid battery draining.)

Setting up for Operation
Fig. 4
Always locate the jet in the driest and safest place possible. Avoid high traffic areas and use flashers and safety
cones. Position the jet so that hose can be pulled directly off of the reel for use. Remember that jetting is most
effective when you jet against the water flow. See Fig. 4 for the recommended positioning of the jet for best visibility
during manhole work. Note that loose hose and damaging corners are minimized when the jet is parked as shown.
(See pages 15 and 16 for instructions on using upper and lower manhole guides.)
When operating upon unlevel ground, position trailer with the hitch (tanksump) end at the downhill side.
Warning: Trailer must be level for low water shutdown to operate correctly. When trailer is on an incline
with hitch end at the down hill side and tank is empty, enough water can be held in the lower front corner
of tank to keep float switch in the operating position.
For non-manhole use, allow extra space for handling the hose before it is wound back on the reel or run the hose
directly to the pipe inlet using extra hose guards to protect the hose from cutting when going around corners.
Warning: Do not unhitch or operate trailer jet unhitched upon unlevel ground.
When unhitching the machine from towing vehicle, always follow these steps:
— Place wheel chocks around trailer jet wheels.
— Lower hitch jack, pin clamp securely.
— Disconnect ball hitch by raising lever and jacking hitch up. Disconnect safety chains and light cord before driving
away.

Pulsation
Pulsation
Control
Pulsation is activated when control knob is turned “in” (see activating pulsator procedure below). As control knob is
turned in, the pulsator stem will force the inlet valve plate open, compressing the valve spring. With inlet valve held
open, center plunger cannot develop pressurized flow. Pulsating action results since only two of the three plungers
are developing pressurized flow.
SS
SS
S
!
To activate pulsator, follow these steps below:
1. Start engine. (Refer to engine operating procedure on page 13)
2. Insert jetting hose several feet into pipe opening. (Refer to setup section on page 14)
3. Advance engine to full throttle and place the reel supply valve in the “on” position (up). (Refer to operating
instructions on page 22)
4. Start turning pulsator control knob “in” (clockwise). You may start to hear a clicking sound made by the inlet
valve plate moving back and forth against pulsator valve stem. Continue turning control knob “in” until
clicking sound disappears and pulsation is evident in jetting hose. (Refer to drawing above)
WARNING: Turning pulsator control knob too far into pump will cause damage to inlet valve
plate, spring, and spring retainer. Increased resistance should be felt when valve spring is reaching
full compression. This is an indicator that you are turning pulsator control knob too far into pump.
5. Pulsation is now fully activated.
To deactivate pulsation, turn pulsation control knob completely out (counter clockwise).
NOTE: Operating pressure will decrease and fluctuate when pulsation is activated. At full throttle, pressure is
approximately 1400-1700 psi.

!
Fuel
Use only clean, fresh, unleaded regular grade gasoline.
CAUTION: Do not mix oil with gasoline.
Octane Rating The octane rating of a gasoline is a measure of its resistance to “knocking”. Use a minimum
of 87 octane of the antiknock is recommended. The antiknock index is posted on service station pumps in the
U.S.A.
Note: If “knocking or pinging” occurs, use a different brand of gasoline or higher octane rating.
Oxygenated Fuel Oxygenates (either ethanol or MTBE) are added to the gasoline. If you use the oxygenated
fuel be sure it is unleaded and meets the minimum octane rating requirement.
The following are the EPAapproved percentages of fuel oxygenates.
ETHANOL: (Ethyl or GrainAlcohol) You may use gasoline containing up to 10% ethanol by volume.
MTBE: (Methyl Tertiary Butyl Ether) You may use gasoline containing up to 15% MTBE by volume.
METHANOL: (Methyl or Wood Alcohol) You may use gasoline containing up to 5% methanol by
volume, as long as it also contains cosolvents and corrosion inhibitors to protect the fuel system.
Gasoline containing more than 5% methanol by volume may cause starting and/or performance
problems. It may also damage metal, rubber, and plastic parts of your fuel system.
Engine Oil
The following engine oils are recommended.
API Service Classifications: SF, SG, SH or SJ.
Oil Viscosity Choose the viscosity according to the temperature in the above chart.
Note: Using multi grade oils (5W-20, 10W30, and 10W40) will increase oil consumption. Check oil level
more frequently when using them.
