Foreseen Use of Tool

This right angle grinder is designed to be used with reinforced resin
bonded depressed centre grinding wheels that have a permitted
rotational speed in excess of 10,000 RPM. See parts lists for details of
available wheel sizes.
The tool is designed to be used for light grinding and dressing of welds,
etc. but not for cutting off. The grinder must never be used if a wheel
guard (disc cover) is not fitted.

Work Stations

The tool should only be used as a hand held hand operated tool. It is
always recommended that the tool is used when standing on a solid
floor. It can be used in other positions but before any such use the
operator must be in a secure position having a firm grip and footing and
be aware of the safety rules to be obeyed when using the grinder.

Putting Into Service

give a measured air pressure at the tool of
90 p.s.i./6.3 bar when the tool is running
with the trigger/lever fully depressed. Use

operate air shut off valve. The air supply should be lubricated. It is
strongly recommended that an air filter, regulator, lubricator (FRL) is
used as shown in Figure 1 as this will supply clean, lubricated air at
the correct pressure to the tool. Details of such equipment can be
obtained from your supplier. If such equipment is not used then the
tool should be lubricated by shutting off the air supply to the tool,
depressurising the line by pressing the trigger on the tool.
Disconnect the air line and pour into the intake bushing a
teaspoonful (5ml) of a suitable pneumatic motor lubricating oil
preferably incorporating a rust inhibitor. Reconnect tool to air supply
and run tool slowly for a few seconds to allow air to circulate the oil.
If tool is used frequently lubricate on daily basis and if tool starts to
slow or lose power.
It is recommended that the air pressure at the tool whilst the tool is
running is 90 p.s.i./6.3 bar. The tool can run at lower and higher
pressures with the maximum permitted working air pressure of
100 p.s.i./7 bar.
