Operation and Safety
• Chuck Key Safety:Achuckkeyleftinthe
chuckcanbecomeadangerousprojectile
whenthespindleisstarted.Alwaysremove
thechuckkeyafterusingit.Developahabit
ofnottakingyourhandoffofachuckkey
unlessitisawayfromthemachine.

Secure Clamping: Athrownworkpiecemay
causesevereinjuryorevendeath.When
swappingthechuckjawpositions,usea
