Changing Grinding Wheels
To avoid malfunction, damage or injury always use a suitable grinding wheel that is in good
condition. Do not use a grinding wheel that is chipped, cracked, or worn. You can check if the
wheel has cracks not visible to the human eye by hanging it up by the central hole and tapping
it with a non-metal object (ie: screwdriver handle). If it is in good condition it will produce a
metallic sound. A dull sound indicates a crack or break. Make sure before carrying out any work
on the Flexisharp that the battery is removed.
Replacement Portek Grinding Wheels are available:
4.5mm thick wheel part number 092/01 and 3.2mm thick wheel part number 092/02
Changing the Grinding Wheel
1. Switch off the machine and remove battery.
2. Remove the grinding wheel protective cover by
unscrewing the 3 retaining screws.
3. Hold the grinding wheel firmly with one hand and
loosen the locking nut.
4. Remove the old grinding wheel and replace with
a new one. Tighten the fixing nut but do not over
tighten - over tightening may cause the wheel
to crack or break. Only use grinding wheels with
an outer diameter of 108mm and inner diameter
of 23mm. The grinding speed of replacement
grinding wheel must meet or exceed the RPM
rating of the machine.
5. Remount the grinding wheel protective cover
onto the machine. Never operate the Flexisharp
without the grinding wheel cover in place. Keep
away from the wheel when it is turning, and
make sure no one is standing close, in the line
of the wheel rotation trajectory. If the grinding
wheel vibrates on start up, turn off the machine
immediately and check that the grinding wheel is
mounted securely!
6 Never try to stop the grinding wheel with your
hands, even if you are wearing safety gloves. The
grinding wheel will cut through gloves and your
hand, causing serious injury. Replace the grinding
wheel when it grinds down to a diameter
of 95mm.
Remove cover
Release wheel by loosening locking nut
Replace with new wheel and ensure
protective shield is in place.
