Do not use oxygen or any other combustible or bottled
gas to power air-powered tools. Failure to observe this

warning can cause explosion and serious personal
injury or death. Use only compressed air to power
air-powered tools. Use a minimum of 25' (7.6 m) of
hose to connect the tool to only compressor. Failure to
comply will result in serious injury or death.

Risk of inhalation: Never directly inhale the air produced by the
compressor.

Risk of electric shock: Do not expose a compressor to rain.
Store it indoors. Disconnect the compressor from the power
source before servicing. The compressor must be grounded.
Do not use grounding adaptors.

Risk of personal injury: Do not direct compressed air from the air hose
towards the user or other people or animal.

Risk of burns: The pump and the manifold generate high temperatures. In
order to avoid burns or other injuries, do not touch the pump, the manifold,
or the transfer tube while the compressor is running. Allow the parts to cool
down before handling or servicing. Keep children and pets away from the
compressor at all times.

Risk of bursting: Do not adjust the pressure switch or safety valve for any
reason. They have been preset at the factory for this compressor’s maximum
pressure. Tampering with the pressure switch or the safety valve may cause
personal injury or property damage.

Risk of bursting: Make sure the regulator is adjusted
so that the compressor outlet pressure is set lower
than the maximum operating pressure of the tool.
Before starting the compressor, pull the ring on the
safety valve to make sure the valve moves freely.
Drain water from the tank after each use. Do not weld
nor repair the tank. Relieve all pressure in the hose
before removing or attaching accessories.
