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 sander.
Foreseen Use of Tool
This vertical grinder is designed to be used with reinforced resin bonded
depressed centre grinding wheels that have a permitted rotational
speed in excess of 6,000 RPM.
The tool is designed to be used for grinding and dressing of welds, etc.
but not for cutting off. The grinder must never be used if a wheel guard
(disc cover) item (33) is not fitted.
Putting Into Service
Air Supply
Use a clean lubricated air supply that will
give a measured air pressure at the tool
of 90 p.s.i./6.3 bar when the tool is run-
ning with the trigger/lever fully de-
pressed. Use recommended hose size
and length. It is recommended that the
tool is connected to the air supply as
shown in figure 1. Do not connect the
tool to the air line system without incor-

porating an easy to reach and operate air shut off valve. The air supply
should be lubricated. It is strongly recommended that an air filter, regu-
lator, 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, de pressurising the line by pressing the trigger on the tool. Dis-
connect the air line and pour into the air inlet bushing a teaspoonful
(5ml) of a suitable pneumatic motor lubricating oil preferably incorpo-
rating 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.
