Congratulations on your purchase of an STG Global product. Your Tanvac Mounted
Vacuum Tanker will give you years of dependable service if the proper operating and
maintenance instructions are observed. We recommend that you read this manual
carefully to become thoroughly familiar with your tanker equipment prior to operation.
1. GENERAL SAFETY PRECAUTIONS
a. Safety Precautions for Entering Tanks
Follow these safety precautions, and insist that those working with you follow them.
Most industrial equipment accidents can be avoided by observing safety precautions.
b. Safety Precautions for Handling Material
DANGER: DO NOT stand near the oil catch muffler or discharge valve when loading
or unloading the tank. Sewer gases vented out of the oil catch muffler will settle
downward. Sewer gases can also be expelled out of the discharge valve when
releasing tank pressure. Inhaling sewer gases can cause severe injury or death.
WARNING: DO NOT allow children or irresponsible people near your work area or
equipment. Fatalities have occurred when children have fallen or climbed into
unattended septic/holding tanks. Secure your work area from entry of unauthorized
persons in the vicinity.
WARNING: Secure all access covers against unauthorized entry after pumping a
septic/holding tank. Fatalities have occurred where children have fallen into
septic/holding tank openings that had not been properly secured. Securely chain and
padlock above ground access openings. Bury underground access openings by at
least six inches of dirt.
WARNING: Always wear protective gloves, eye protection and, appropriate clothing
when working with sewage affluent or septage. These materials may contain
hazardous chemicals, disposed of through the drain, which can cause severe injury
or even death due to contact. These affluent also contain bacteria, which can be a
source of infection, especially if exposed to open cuts or sores.
DANGER: DO NOT enter a transport, septic, or holding tank without cleaning and
providing adequate ventilation to the interior of the tank. Sewer gas is deadly if
inhaled; in addition, it depletes the oxygen in a confined space, which can cause
asphyxiation.

2
DANGER: DO NOT enter a transport, septic, or holding tank without using a
respirator that supplies grade D breathing air or a self-contained breathing apparatus.
In addition, DO NOT use this equipment without training and familiarity with it.
Entering a tank exposed to sewage affluent without a correct breathing apparatus, or
with improper use of it, can cause death.
DANGER: DO NOT enter a transport, septic, or holding tank without protective
clothing. Sewer gas can be absorbed through the skin causing serious injury or
death.
WARNING: When entering a transport, septic, or holding tank, always have someone
standing by to provide assistance, and always have a respirator that supplies grade D
breathing air or a self-contained breathing apparatus on hand for them. In the event
of an attempted rescue, this equipment is necessary to prevent death of the rescuer.
WARNING: Attach a safety-harness and rope to any person that enters a transport,
septic, or holding tank. Have the safety-harness rope held by a person standing by to
provide assistance outside the tank. An attempted rescue without the advantage of a
rope and harness can be life threatening to the rescuer.
WARNING: Entry into a transport, septic, or holding tank is confined space entry.
Persons entering these tanks for any purpose must be trained in and follow OSHA
confined space safety procedures.
c. Safety Precautions for Operating Equipment
DANGER: Stop the truck motor, remove all persons from the truck cab, and chock
the truck tires before servicing any component under the truck; this includes
lubricating the vacuum pump or the PTO driveline. Contact with a rotating
mechanism can cause entanglement that can lead to death. A truck that begins to roll
is a crushing hazard that can lead to death.
WARNING: Keep hands, feet, hair, and clothing away from moving parts. Contact
with a moving mechanism can cause entanglement that can lead dismemberment or
death.
WARNING: Escaping hydraulic oil under pressure can have sufficient force to
penetrate your skin, which can cause serious injury. Before operating hydraulic
components, be sure all connections are tight and hoses are not damaged. Relieve
all pressure before disconnecting hydraulic lines or repairing leaks.
CAUTION: When off-loading under pressure, maintain control of the end of the hose.

Pressurised discharge can cause a hose end to whip about and create the potential
for spraying persons in the area
WARNING: Keep all shields in place. Shields and covers are designed to protect the
operator from entanglement in moving parts, which can lead to serious injury or
death. DO NOT remove shields from the unit except when servicing; then, replace
immediately.
WARNING: The truck’s cornering and braking abilities are reduced when the tank is
loaded. Drive at a reasonable speed with a loaded tank; reduce speed on rough or
hilly terrain, before making an anticipated stop, and when cornering.
WARNING: Make certain everyone is clear of the tanker truck and the immediate
area before starting the engine, engaging power, and operating the equipment. The
inherent hazards of septic pumping can cause serious injury or death to untrained
persons that enter this area.
WARNING: DO NOT allow anyone to ride on the outside of the tanker truck when it is
in motion. Failure to follow this precaution could result in persons falling off the truck
and possibly getting run over, which could cause serious injury or death.
WARNING: Before backing-up the truck, inspect the area to be backed into, and
clear all hazards, pets, and people from it. Make sure that backup lights and the
back-up alarm are maintained and in good working condition. Because of the truck
mounted tank, the driver will experience a large blind spot behind the truck. Fatalities
have occurred when persons were run over by a tanker truck.
CAUTION: Avoid contact with the vacuum pump during or immediately after
operation. Operating temperatures can range from near 200oF to over 00oF,
depending on the make and model of pump and on the working conditions. Contact
with a hot vacuum pump can cause severe burns.
2. GENERAL SAFETY RULES
WARNING: Water at high pressure can be dangerous and can cause damage if
the operator is careless. Never allow anyone to operate this pressure washer
unless they are familiar with the safety precautions.
1. NEVER direct the spray towards any person or animal.
2. NEVER hold your finger over the high-pressure nozzle.
3. NEVER allow children or untrained personnel to use this machine.

4
4. NEVER operate the machine with any of the covers removed.
5. NEVER attempt any repairs to this machine. Always refer to your dealer.
6. NEVER supply any liquid other than water to the water inlet.
7. NEVER use the detergent pickup facility to introduce flammable liquids/solvents,
e.g. paint thinners, petrol, oil as there is a risk of explosion.
8. ALWAYS release any residual pressure in the system by turning off the water
supply and operating the trigger before disconnecting any hose or accessory.
9. ALWAY S keep the machine itself dry and well clear of water spray.
10. ALWAY S wear protective clothing and safety glasses. Loose particles and other
debris may be propelled at high speed by the water jet.
11. ALWAY S grip the gun firmly and expect the spray gun to ‘kick’ when starting.
12. ALWAY S respect the requirements of the local water company. Pressure washers
may only be connected to the mains drinking water supply if a system separator
(also known as a backflow preventer) is installed in the supply hose.
13. ALWAY S disconnect from the water supply, and ensure the system is completely
drained when not in use. Store in a cool dry location.
14. ONLY use chemical cleaning agents (detergents), that are approved for pressure
washers.
15. WARNING High pressure water jets can be dangerous if subject to misuse. The
jet must not be directed at a person or anything that they are wearing.
16. NEVER direct the jet at electrical equipment or the machine itself.
17. WARNING High pressure hoses, fittings and couplings are important for the
safety of the machine. Use only hoses, fittings and couplings recommended by
the manufacturer.
18. WARNING Water that has flowed through a system separator (also known as a
backflow preventer) is considered non-drinkable
19. NEVER use the pressure washer if the inlet/outlet hoses or important parts of the
machine are damaged.

3. HIGH PRESSURE WATER SAFETY
WARNING
An injury caused by high pressure water jets can be serious. In the event of any
water jet injury:
• Seek medical attention immediately. Do not delay!
• Inform the doctor of the cause of the injury. 
• Tell the physician what type of waterjet project was being performed at the time
of the accident and the source of the water. 
A. Medical Alert
This patient may be suffering from a water jet injury. Evaluation and management
should parallel that of a gunshot injury. The external manifestations of the injury
cannot be used to predict the extent of internal damage. Initial management should
include stabilisation and a thorough neurovascular examination. X-rays can be used
to assess subcutaneous air and foreign bodies distant from the site of injury.
Injuries to the extremities can involve extensive nerve, muscle, vessel damage, as
well as cause a distal compartment syndrome. Injuries to the torso can involve
internal organ damage. Surgical consultation should be obtained. Aggressive
irrigation and debridement is recommended. Surgical decompression and exploration
may also be necessary.
Angiographic studies are recommended pre-operatively if arterial injury is suspected.
Bandages with a hygroscopic solution (MgSO4) and hyperbaric oxygen treatment
have been used as adjunctive therapy to decrease pain, edema and subcutaneous
emphysema. Unusual infections with uncommon organisms in immunocompetent
patients have been seen; the source of the water is important in deciding on initial,
empiric antibiotic treatment, and broad-spectrum intravenous antibiotic treatment,
and broad-spectrum intravenous antibiotics should be administered. Cultures should
be obtained.

7
• Never use this unit in any type of rescue operation where the vacuum is used for the
rescue. 
• Operating the unit inside a building or confined areas can create additional risks to
the unit, operators and building occupants. Engine exhaust gas can reach deadly
levels. Heat buildup from the engine and blower discharge can overheat people and
equipment. 
• Never use an air mover machine for vacuuming hydrocarbon or flammable materials
unless the flash point of the material is 60° (C) or higher. Pressurised or pump
off-loading is not permitted unless the flash point of the material is 50° (C) or higher
unless nitrogen is present. 
• Never operate engines where there are or can be combustible vapors. Vapors pulled
in to an engine air intake can cause engine acceleration and over-speeding. This can
result in death, injury and property damage. 
• Reference to OSHA regulations are for informational purposes only and not intended
as legal advice. 
• The use of this equipment in the removal or handling of any regulated substance or
material must be performed in strict accordance with all applicable federal, state and
local laws and regulations, and approved safety and personal protection equipment
and clothing must be used and worn at all times.
• Never use an air mover machine to vacuum dusty materials until the Safety Data
Sheet(s) (SDS) have been consulted to determine if the dust(s) have an explosive
potential (Combustible Dusts). Only air mover units that are part of a verified assured
grounding system that have bags, doors and any other non-welded debris body
components grounded to the debris body can be used if the materials contain
combustible dusts.
