3.2 General safety notes 

Metalworking machines can be 
dangerous if not used properly. 
Therefore the appropriate general 
technical rules as well as the 
following notes must be observed. 

Read and understand the entire 
instruction manual before attempting 
assembly or operation. 

Keep this operating instruction close 
by the machine, protected from dirt 
and humidity, and pass it over to the 
new owner if you part with the tool. 

No changes to the machine may be 
made. 

Daily inspect the function and 
existence of the safety appliances 
before you start the machine. 
Do not attempt operation in this 
case, protect the machine by 
unplugging the power cord. 

Remove all loose clothing and 
confine long hair. 

Before operating the machine, 
remove tie, rings, watches, other 
jewellery, and roll up sleeves above 
the elbows.  

Wear safety shoes; never wear 
leisure shoes or sandals. 

Always wear the approved working 
outfit. 

Do 

not

 wear gloves. 

Wear goggles when working 

Install the machine so that there is 
sufficient space for safe operation 
and work piece handling. 

Keep work area well lighted. 

The machine is designed to operate 
in closed rooms and must be placed 
stable on firm and levelled ground. 

Make sure that the power cord does 
not impede work and cause people 
to trip. 
Keep the floor around the machine 
clean and free of scrap material, oil 
and grease. 

Stay alert!  
Give your work undivided attention. 
Use common sense. Do not operate 
the machine when you are tired. 

Keep an ergonomic body position.  
Maintain a balanced stance at all 
times. 

Do not operate the machine under 
the influence of drugs, alcohol or 
any medication. Be aware that 
medication can change your 
behaviour.  

Never reach into the machine while 
it is operating or running down. 

Never leave a running machine 
unattended. Before you leave the 
workplace switch off the machine. 

Keep children and visitors a safe 
distance from the work area. 

Do not operate the electric tool near 
inflammable liquids or gases. 
Observe the fire fighting and fire 
alert options, for example the fire 
extinguisher operation and place. 

Do not use the machine in a dump 
environment and do not expose it to 
rain. 

Work only with well sharpened tools. 

Always close the chuck guard and 
pulley cover before you start the 
machine. 

Remove the chuck key and 
wrenches before machine operation. 

Specifications regarding the 
maximum or minimum size of the 
work piece must be observed. 

Do not remove chips and work piece 
parts until the machine is at a 
standstill. 

Do not stand on the machine. 

Connection and repair work on the 
electrical installation may be carried 
out by a qualified electrician only. 

Have a damaged or worn power 
cord replaced immediately. 

Never place your fingers in a 
position where they could contact 
any rotating parts or chips. 

Check the save clamping of the 
work piece before starting the 
machine. 

Don’t exceed the clamping range of 
the chuck. 

Work pieces longer than 3 times the 
chucking diameter need to be 
supported by the tailstock or a 
steady rest. 

Avoid small chucking diameters at 
big turning diameters. 

Avoid short chucking lengths. 

Avoid small chucking contact. 

Never exceed the max speed 
limitation of the work holding device. 

Choose a small spindle speed when 
working unbalanced work pieces 
and for threading and tapping 
operations. 

Any work piece stock extending the 
rear end of the headstock must be 
covered on its entire length. High 
danger of injury! 

Long work pieces may need a 
steady rest support. A long and thin 
work piece can suddenly bend at 
high speed rotation. 

Never move the tailstock or tailstock 
quill while the machine is running. 

Remove cutting chips with the aid of 
an appropriate chip hook when the 
machine is at a standstill only.  

Never stop the rotating chuck or 
work piece with your hands. 

Measurements and adjustments 
may be carried out when the 
machine is at a standstill only. 

Setup, maintenance and repair work 
may only be carried out after the 
machine is protected against 
accidental starting by pulling the 
mains plug. 

 

3.3 Remaining hazards 

When using the machine according 
to regulations some remaining 
hazards may still exist. 

The rotating work piece and chuck 
can cause injury. 

Thrown and hot work pieces and 
cutting chips can lead to injury. 

Chips and noise can be health 
hazards. Be sure to wear personal 
protection gear such as safety 
goggles and ear protection. 

The use of incorrect mains supply or 
a damaged power cord can lead to 
injuries caused by electricity.
