INSTRUCTIONS
This product is designed for removing or polishing
material using abrasives or polishing attachments. No
other use permitted. For professional use only.
Before servicing the power tool, the supply of
compressed air must be disconnected or shut off.
When disposing of components, lubricants, etc ... ensure
that the relevant safety procedures are carried out.
The tool is designed for a working pressure of 6.3 bar (90
psig). The compressed air must be clean. The installation of
a filter is recommended. For maximum efficiency and
performance, comply with the specification of the air hose.
Drain the air hose
(Refer to figure no.1 for compressed air connection)
Ømini mm = 13 (1/2")
To obtain maximum efficiency from the pneumatic tool,
preserve its features and avoid repeated repairs, a routine
inspection and repair programme are recommended at least
every 500 operating hours or every 6 months as a minimum.
In heavy-duty conditions, the inspection program can be
performed every 3 months.
- Disassemble the tool, clean and check the parts carefully.
- Check the condition of the bearings and inspect the vanes
for wear and surface condition.
For dust extraction, please contact your local sales.
Check the free speed of the tool at regular intervals and
after each operation or maintenance task. Remove the
abrasive to check the speed. The maximum allowed speed
shown on the tool must not be exceeded and the vibration
level must not be excessive.
This tool is fitted with vanes which can operate without
lubricated air. However, a small amount of oil allows the tool
to provide full power and lengthens its life.
The use of dry air with no trace of oil may reduce the life of
vanes.
Risk of icing
Ice can cause continued running after the start lever has
been released.
Always use a dry air supply to avoid the risk of icing.
