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, hiding or
total or partial removal of the guards.
Never exceed the maximum working pressures of the
equipment components.
Pressure hazards
Safety requires that a pressure relief air shut-off valve must be installed
in the pump motor supply system to allow trapped air to escape
when the supply is shut off.
Without this precaution, residual air from the motor may cause the
motor pump to operate and cause a serious accident.
Also, a fluid drain valve must be installed in the fluid system so that the
fluid can be drained (after shutting off motor air and decompressing
it) before any intervention on the equipment. These valves must
remain closed for air and open for the product during the
intervention.

Given the diversity of the materials 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 cannot be held responsible:
poor compatibility of materials in contact,
Inherent risks to personnel and the environment,
Wear and tear, malfunctions, material or equipment
malfunctions, as well as the quality of the finished.
The user shall identify and prevent from potential dangers inherent to
the materials used, such as:
Toxic vapors.
Fire.
Explosions.
It will determine the risks of immediate reactions or reactions due to
repeated exposures to personnel.
SAMES KREMLIN declines any responsibility, in case of:

582156110-EN-indC-Pump-20F50 pH.docx 20/11/2020 19
4Environment
The equipment is installed on a horizontal, stable and flat floor (e.g.
concrete slab).
Non-movable equipment must be fixed to the ground by suitable
mounting devices (spit, screws, bolts, etc.) to ensure its stability during
use.
To avoid risks due to static electricity, the equipment and its
components must be grounded.
For pumping equipment (pumps, lifts, chassis, etc.), a 2.5
mm section wire is attached to the equipment. Use this
wire to connect the equipment to the general
“ground”. In the case of severe environments
(insufficient mechanical protection of the earthing wire,
vibrations, moving equipment, etc.) where damage to
the earthing function is likely, the user must replace the
2, 5 mm wire supplied, by a device more suited to its
environment (larger wire section, earth braid, fixing by
eye lug,…).
Have the ground continuity checked by a qualified
electrician. If ground continuity is not assured, check
terminal, wire and grounding point. Never operate the
equipment without first resolving this problem.
The gun must be "grounded" through the air hose or
fluid hose. When spraying from a gun, the fluid hose
must be conductive.
The equipments to be painted must also be “grounded”
by means of clamps fitted with cables or, if suspended,
by means of hooks which must be kept clean
permanently.
Note: all objects in the work area must also be
grounded.
Do not store more flammable materials than necessary
inside the work area.
These materials must be stored in approved, grounded
containers.
Use only grounded metal pails for flushing solvents.
Cardboard and papers are to be banned. They are very
bad conductors, even insulators.
