Remaining Hazards; Machine Specifications; Machine Description; Technical Data - Jet 4224B Mode D'emploi

Connection and repair work on the electrical installation may
be carried out by a qualified electrician only.
(Warning: Wait five minutes for DC-bus capacitors discharge
before accessing the AC drive unit.)
Have a damaged or worn power cord replaced immediately.
Make all machine adjustments or maintenance with the
machine unplugged from the power source.

3.3 Remaining hazards

When using the machine according to regulations some
remaining hazards may still exist.
The rotating workpiece can cause injury.
Workpieces that are inhomogeneous or weak can explode
when being processed due to centrifugal force.
Only process selected woods without defects.
Unbalanced workpieces can be hazardous.
Loss off compressed air supply can be hazardous.
Injuries can occur when feeding tooling, if tool supports are
not correctly adjusted or if turning tools are blunt.
Risk of kickback. The tooling is caught by the rotating
workpiece and thrown back to the operator.
Thrown workpieces and workpiece parts can lead to injury.
Dust and noise can be health hazards. Be sure to wear
personal protection gear such as safety goggles and dust
mask. Use a suitable dust collection system.
The use of incorrect mains supply or a damaged power cord
can lead to injuries caused by electricity.
