The Seller guarantees that the 
supplied product is free from material 
defects and manufacturing faults. This 
warranty does not cover any defects

excluded. 

This warranty includes all guarantee

agreements concerning warranties. 

The warranty period is valid for eight 
hours of daily use. If this is exceeded, 
the warranty period shall be reduced in 
proportion to the excess use, but to no 
less than three months. 

Returning rejected goods requires the 
prior express consent of the Seller and 
is at the Buyer’s risk and expense.

3.  Safety 

3.1 Authorized use 

This drill press is designed for drilling 
wood and machinable metal and 
plastic materials only.  
Machining of other materials is not 
permitted and may be carried out in 
specific cases only after consulting 
with the manufacturer.  

Never cut magnesium- 
high danger of fire! 

The workpiece must allow to safely be 
loaded and clamped for machining. 

The proper use also includes 
compliance with the operating and 
maintenance instructions given in this 
manual. 

The machine must be operated only 
by persons familiar with its operation 
and maintenance and who are familiar 
with its hazards. 

The required minimum age must be 
observed. 

The machine must only be used in a 
technically perfect condition. 

When working on the machine, all 
safety mechanisms and covers must 
be mounted. 

In addition to the safety requirements 
contained in these operating 
instructions and your country’s 
applicable regulations, you should 
observe the generally recognized 
technical rules concerning the 
operation of wood- and metal-working 
machines. 

Any other use exceeds authorization. 
In the event of unauthorized use of the 
machine, the manufacturer renounces 
all liability and the responsibility is 
transferred exclusively to the operator.  

 

3.2 General safety notes 

Wood and 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.
