DANGER!

Potential hazard that will result in serious injury or loss of life.

•Keep children away from the work area. Do not allow children to handle

power tools.

•Keep air hose away from heat, oil, and sharp edges. Check air hose for

wear before each use and ensure that all connections are proper.

•Always ensure that the workpiece is firmly secured leaving both hands free

to control the tool.

•Always ensure that the tool has stopped before putting it down after use, for

safety purpose and to prevent possible damage to the tool/user.

•Keep proper footing at all times in order to ensure correct balance.

•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 the compressed air to power the

air-powered tools. Use a minimum of 25' (7.6 m) of hose

to connect the tool to the compressor. Failure to comply

will result in serious injury or loss of life.

•Risk of electric shock: Do not expose the compressor to rain. Store it

indoors. Disconnect the compressor from power source before servicing.

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 personnel.

•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 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 away from the compressor

at all times.

•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 that the valve moves freely. Drain water from tank

after each use. Do not weld or repair tank. Relieve all

pressure in the hose before removing or attaching

accessories. MC-OM-22
