with a rated pressure of 10 bar, or more should be used. Never attempt to
repair damaged hoses.
8. NEVER abuse the compressor by standing on it.
AIRLINE HOSES
1. ALWAYS ensure that equipment or power tools used in conjunction with the
compressor have a safe working pressure exceeding that of the machine.
2. ALWAYS keep the air hose away from any attached air tools and ensure
that the operator is not restricted by the length of the hose.
3. ALWAYS take care when a long air hose is required in the work area as it
presents a trip hazard. Coil the hose away as soon as the job is finished.
