5 HOW TO USE
5.1 Mounting the drill bits
Crushing and Cutting
Before mounting and/or removing the cutting bits, always disconnect the air supply hose.
Protective gloves
Before mounting and/or removing the cutting bits, wear suitable protective gloves.
1. Insert a cutting tip (with a diameter between 1.5 mm and 10 mm) inside the spindle.
2. Close the jaws of the spindle by manually rotating the outer ring in a clockwise direction,
so that the bit is held secure by the jaws themselves.
3. Insert the key into one of the circular holes on the spindle, then rotate clockwise to tighten
the jaws of the spindle. When finished, remove the key!
Centring the bit
Always check the centring and linearity of the bit, before using the tool.
5.2 Power On / Off
(Personal Protective Equipment) PPE
Before using the grinder, wear suitable work clothing, gloves, shoes and protective goggles.
Also wear a mask if you work with materials that produce dust or fumes.
Also wear protective devices for the ears (hearing protectors), such as earmuffs, earplugs,
etc.
Workspace
Be familiar with the work area.
Always check the work area before using the grinder.
Keep the work area clean, uncluttered and well lit.
Machining metals, such as magnesium, can lead to the formation of potentially explosive or
combustible dust or fumes; therefore, avoid the presence of flames or hot surfaces in the
work area.
