Safety instructions

• Always wear face shield or protective eye glasses.
• Always wear hearing protection when working with pneumatic tools; otherwise you risk

permanently impairing your hearing.

• Never use a tool with damaged punch or pad.

Compressed air feed and connections

Warning!

Use only compressed air as power source for pneumatic tools. Do not use acid

and flammable gases as power source as the mixture can explode and cause injury.

The air

pressure must not exceed 6.2 bar.

• Compressors must have sufficient capacity to provide enough compressed air and air

flow for the intended application. A pressure fall in the system can reduce the tool’s
power. Compressed air hoses for industrial use should be placed so that the highest
point on the inclination is nearest to the compressor. An easily accessed water separator
should be installed at the lowest point. Water separators should be emptied at least
once a day or more often if needed. Dirt and water in the air hoses are the most frequent
causes of wear in pneumatic power tools. The tool’s connections should be equipped
with pressure regulators with water separator directly at the site of connection. A filter
helps to achieve maximum efficiency and minimise wear. The filter must have sufficient
flow capacity for the intended assembly site or connecting point. The filter must be kept
clean to provide clean compressed air to the tool. See the manufacturer’s instructions
for proper filter care. A dirty and clogged filter means less pressure which diminishes the
tools efficiency The pressure regulator must be able to reduce the pressure to 6.2 bar
(90 PSI).

• Air hoses should tolerate at least 10.5 bar working pressure or 150 % of the maximum

pressure the system can provide. The feeder hose should have a quick connecting piece
for quick removal from the nipple of the tool.

• Make sure that the compressed air fed to the tool does not exceed the maximum

permissible working pressure (6.2 bar).

• Do not expose the hoses to heat.

Lubrication

Note!

Lubricate with a few drops of oil in the air connecting piece before the tool is used the

first time.

• Regular but moderate oiling is required for best effect. Oil fed into the hoses does not

lubricate the components. If mist lubrication is not used for the compressed air, the oil in
the tool’s air nipple should be filled one or to times per day. Only a few drops of oil are
needed each time (1-2 drops). If too much oil collects in the tool it is blown out into the
air when the tool is used. Mist lubrication.
