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.
• Disconnect Power: Disconnectthelathe
frompowerbeforeinstallingandremoving
the chuck or doing any maintenance or
adjustments.Accidentallathestartupcan
causesevereinjuryordeath.
• Secure Clamping: Athrownworkpiece
maycausesevereinjuryorevendeath.
Whenswappingthechuckjawpositions,
keep in mind that maximum gripping
forceisattainedatfulljawandjawscrew
engagement. Ifonlyoneispartiallyengaged,
overallclampingforceisreduced.
• Speed Rates: Operating the lathe where
maximumchuckspeedisexceeded,orattoo
