Diamond grinding wheel rubs
against the steel guard when fitted
Use more spacers under the diamond grinding wheel. If the wheel is too flat in
profile purchase an extended nut and spacer instead of using the spacer washers.
Check to see that the dust guard’s mounting collar is pushed down hard against the
grinder’s bearing housing.
Use a deeper dished diamond grinding wheel.
Dust guard mounting boss will not
push over the insert collar.
Push hard because sometimes the paint is applied thicker than normal and this is
enough to tighten the fit. Unscrew the clamping screws until they are no longer
protruding into the inside of the mounting collar.
Change the insert to a smaller thickness.

The grinder jum ps and debris is
being thrown from under the seal
Use a less aggressive diamond grinding wheel. PCD scraper wheels can cause this
problem. It is rare for it to occur with diamond segmented grinding wheels.
SAFETY
Always turn on the vacuum before using the dust guard.
Do not use diamond grinding wheels with a larger diameter than recommended for the guard.
Always use the original main seals.
Use a dust collector vacuum with sufficient power and only use one attachment for each dust collector.
Wear suitable breathing safety equipment while grinding. Wear hearing protection while grinding.
Wear eye protection goggles while grinding.
Do not lift the guard from the surface being ground while the grinder is still operating.
Keep the filters of the vacuum clean. Empty dust into sealed receptors or use sealed plastic bags.
Do not sweep floors after grinding which creates airborne dust - always use a vacuum and floor nozzle to remove surface dust.
Never place any part of your body or objects under the dust guard while the motor is activated.
Do not grind over electrical cables, metal objects or loose material that could fly out from under the main seal at high speed.
Clean the dust guard thoroughly with a brush and vacuum to remove loose dust before storage.
Before removing the hose from the dust collector shake the hose with the vacuum motor operating to dislodge loose dust that
may fall out later.
