tion
Mounted abrasive equipment
T
WARNING Air under pressure can cause
serious injury
►
Always shut off air supply, drain hose of air
pressure and disconnect tool from air supply when

T
WARNING Wrong abrasive wheel can burst
and cause serious injury or death
►
Use a abrasive wheel with a permitted speed
higher or equal than the air grinder speed
►
Do not use other abrasive wheel than specified by
the manufacturer. See Section
Design and func-
tion .
• Use only recommended sizes and types of abras-
ives
• Do not use mounting wheels that are chipped or
cracked, or may have been dropped
• Correct mounting is necessary to prevent injury
from broken mounted wheels
• Do not fit a wheel soaked in any fluid
• Grinding wheels should be a free fit but not loose
on the spindle to prevent stress at the hole. Do not
use reducing bushes to fit large hole grinding
wheels
• Attach wheel with flanges conforming to interna-
tional standard and in good condition
• Flanges shall be clean, have flat contact surface
and be without cracks and burrs
• Do not use unauthorised bushings or adaptors to
attach large hole abrasive wheels
• Use blotters when delivered with the grinding
wheel
• Do not mismatch wheel- and spindle thread
• Spindle and spindle threads shall be without
damage or wear
• Mount the wheel correctly and tighten to pre-
scribed torque to prevent spin off when the air
grinder is turned off
• Test run every new mounted wheel in a safe posi-
tion for 30 seconds. Be sure to use a barrier (such
as under a heavy work table) to stop any possible
broken wheel parts. Stop immediately if vibration
is excessive
Correct working with the grinder
Read the Section Safety instructions before using the
grinder.
T
WARNING Failure to follow correct working
practices can result in serious injury or death
►
Ensure that the workpiece is properly supported
►
Avoid wheel jamming when cutting-off. Support
the workpiece on both sides of the cut line to pre-
vent the wheel becoming trapped. If jamming oc-
curs, release the throttle and ease the wheel free.
Check the wheel is undamaged and properly se-
cured before continuing
►
Check that no bystanders are in the vicinity
►
Ensure that sparks do not cause a hazard to people
or materials
►
There is a risk of electrostatic discharge if the tool
is used on plastic and other non-conductive mater-
ials
