Security devices
Attention
Guards (motor cover, coupling guard, housings, ...) are set
up for safe use of the equipment.
The manufacturer cannot be held responsible for any bodily
injury as well as failures and / or damage to the equipment
resulting from the destruction, the occultation or the total or
partial removal of the protectors.
Never exceed the maximum working pressures of the
equipment components.
Danger of Pressure
Safety requires that a pressure relieve shutoff valve be mounted on
the pump motor supply circuit to allow trapped air to escape when
the air supply is shut off.
Without this precaution, the residual air from the engine may cause
the motor pump to operate and cause a serious accident.
Similarly, a material bleed valve must be installed on the material
circuit so that material pressure can be relieved (after shutting off air
motor and decompressing it) before any intervention on the
equipment. These valves should remain closed for air and open for
the material during the procedure.

Safety instructions
11
Injection hazards
"HIGH PRESSURE" technology requires the utmost care.
Operation can cause dangerous leaks. There is a risk of product
injection into exposed parts of the body, which can lead to serious
injury and the risk of amputation :
An injection of product into the skin or other parts of the
body (eyes, fingers ...) must be treated urgently by
appropriate medical care.
Do not look at the gun nozzle when it is under pressure.
Never point the gun nozzle at another person.
Never attempt to stop the jet with the body (hands, fingers
...) or with rags or similar.
Fire hazards, explosion,
electric arc, static
electricity
Improper grounding, insufficient ventilation, open flames or sparks can
cause an explosion or fire which could result in serious injury.
To avoid these risks, especially when using pumps, it is imperative:
Before operating the Pump supply system make sure that all
Pump equipment and material containers are grounded,
To ensure good ventilation,
Keep the work area clean and free of rags, papers, solvents,
Do not operate electrical switches in the presence of vapors
or during removal,
Immediately stop the application in the presence of arcs,
Store all liquids outside the work areas.
Use products whose flash point is as high as possible to avoid
any risk of formation of flammable gases and vapors
(consult the product safety data sheets).
To equip the drums with a lid to reduce the diffusion of gases
and vapors in the cabin.
It is forbidden to pump explosive materials

Safety instructions
12
Toxic products hazards
Toxic products or vapors can cause serious injury through contact with
the body, in the eyes, under the skin, but also by ingestion or
inhalation. It is imperative:
To know the type of product used and the dangers it
represents,
Store the products to be used in appropriate areas,
Contain the product used in the application in a container
designed for that purpose,
Treat product waste with the legislation of the country where
the equipment is used,
To wear protective clothing designed for that purpose,
Wearing goggles, hearing protectors, gloves, shoes,
coveralls and masks for the respiratory tract.
Attention
The use of halogenated hydrocarbon solvents and
products containing these solvents in the presence of
aluminum or zinc is prohibited.
Failure to follow these instructions exposes the user to the
risk of explosion resulting in serious injury or death.

Safety instructions
13
2.2 Integrity of the material
Material recommendations
Protectors are put in place for safe use of the equipment.
The manufacturer cannot be held responsible in case of:
Bodily injury.
As well as breakdowns and / or damage to the equipment
resulting from the destruction, the misuse or the total or
partial withdrawal of the protectors.
Pump
It is imperative to be aware of the compatibility of the motors and
pumps before coupling them together as well as the special safety
instructions. These instructions can be found in the instruction manuals
of the pumps.
The air motor is intended to be coupled to a pump. Never modify the
coupling system. Keep hands away from moving parts. The moving
parts must be kept clean. Before commissioning or using the motor
pump, read carefully the DECOMPRESSURIZATION PROCEDURE. Check
the proper operation of the pressure relief and bleed air valves.
Tubing
Recommendations
Keep hoses away from traffic areas, moving parts and hot
areas.
Never subject hoses being produced to temperatures
above 80°C or below 0°C.
Do not use hoses to pull or move equipment.
Tighten all connections and hoses and couplings before
operating equipment.
Check hoses regularly and replace if damaged.
Never exceed the maximum working pressure (MWP) stated
on the hose.
When fitting the hoses and the gun: PPE must be worn.
Tighten to full stop (hoses + gun).

Safety instructions

Products implemented
Given the diversity of the products implemented by the users and the
impossibility of listing all the characteristics of the chemical
substances, their interactions and their evolution over time SAMES
KREMLIN can not be held responsible:
The poor compatibility of materials in contact.
inherent risks to staff and the environment.
Wear and tear, maladjustment, malfunction of equipment or
machines and the quality of the finished product.
The user will have to identify and prevent the potential dangers
inherent to the implemented products such as:
Toxic vapors.
Fire.
Explosions.
It will determine the risks of immediate reactions or due to repeated
exposures to the staff.
SAMES KREMLIN declines any responsibility, in case of:
Bodily or psychic injuries.
Direct or indirect material damage due to the use of
chemical substances.

Environment
15
3Environment
The equipment must be installed on a horizontal, stable and flat
ground (eg concrete slab).
Non-moving equipment must be fixed to the ground by suitable
fasteners (spit, screws, bolts, ...) to ensure their stability during use.
To avoid risks due to static electricity, the equipment and its
components must be grounded.
In combination with a pneumatic motor, the hydraulics will
be earthed with the earth cable of this motor. This earth
cable must be connected to a safe earth.
Have the earth continuity checked by a qualified
electrician. If earth continuity is not assured, check terminal,
wire and grounding point. Never operate the equipment
without solving this problem.
Do not store more flammable products than necessary
inside the work area.
These products must be stored in approved containers and
grounded.
Use only grounded metal buckets for the use of rinse
solvents.
Cartons and papers are to be banned. Indeed they are very
bad conductors, even insulators.

Material marking
Each device is equipped with an identification plate with the
name of the manufacturer, the reference of the device, important
information for the use of the device (pressure, power, ...) and
sometimes against the pictogram shown below.
The equipment is designed and manufactured with high quality
materials and components that can be recycled and reused.
European Directive 2012/19 / EU applies to all devices marked with
this logo (crossed out bin). Find out about the collection systems
available for electrical and electronic devices.
Comply with the rules in your area and do not dispose of old
appliances with household waste. Proper disposal of this old device
will help prevent adverse effects on the environment and human
health.
