Remaining Hazards; Machine Specifications; Machine Description; Technical Data - powermatic 4224B Gebrauchsanleitung

Workpieces with cracks may not be used.
Remove the chuck key or dowel pins before turning the
machine on.
Always close the belt cover.
Specifications regarding the maximum or minimum size of
the workpiece must be observed.
Test each set-up by revolving the work by hand to insure it
clears the tool rest and bed. Check setup at the lowest
speed before you increase to the operating speed.
Do not remove chips and workpiece parts until the
machine is at a standstill.
Never stop work pieces with the hand during run out.
Do not attempt to engage the spindle lock pin until the
spindle has stopped.
Never take measurements on a rotating workpiece.
Do not stand on the machine.
Do not obstruct the air flow on heat sinks of AC-drive
(allow natural cooling).
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.
