SAFETY PRECAUTIONS & HIGH PRESSURE WARNINGS
i
Pay close attention to ALL warnings, as serious injury or
damage could result! Throughout the ELF-1 Operation
Manual, the symbol shown at right will designate where
particular attention should be paid and caution should be
exercised.
i
Be aware that even at the relatively low pressures delivered
by the ELF-1, improper use can cause permanent damage to
some systems and components, and can be hazardous to the
operator and others in the vicinity.
i
Under no circumstances should the Pressure Regulator be set fully open at 15
PSI when initially applying pressure from the ELF-1 to a system of any kind.
Always start with a very low pressure and gradually increase it. Always observe
the amount of component deflection taking place under pressure.
i
Never leave any system or component under high pressure. Avoid leaving the
ELF-1 hoses and power cables connected to the vehicle under test when not
in use for extended periods of time.
i
When conducting EVAP testing of the vehicle fuel vapor recovery system, it is
STRONGLY RECOMMENDED that a non-combustible inert gas – such as
nitrogen – be used instead of shop air. Use of shop air may create a HIGHLY
DANGEROUS situation which will support the combustion of the volatile fuel
vapors in the EVAP system, resulting in serious personal injury and damage.
i
Always follow the vehicle manufacturer’s recommendations and any required
test procedures when testing the vehicle EVAP system.
i
EVAP testing must comply with any applicable Federal and State regulations.
i
Always wear safety goggles when applying pressure to a system or component.
i
Do NOT tamper with or modify any of the ELF-1 components, including hoses,
cables or other replacement parts. This will void the warranty, and may cause
the unit to malfunction or to incur damage to the vehicle under test or other
property.
i
Never use the ELF-1 on an engine that is running.
i
The ELF-1 should ONLY be used with RTI Patented Fluid
Part Number: 438100 (4 oz bottle) or 438115 (6 Bottles)
i
The ELF-1 should only be operated and stored in the upright position.
