Caution:  
The machine is heavy! 

382kg 

Assure the sufficient load capacity 
and proper condition of your lifting 
devices. 
Never step underneath suspended 
loads. 

Carefully place the machine to the 
floor. 

Use 4 anchor bolts of sufficient size 
and length. 

Use a machinist’s precision level to 
make sure that the machine table is 
level. 
Loosen mounting bolts, shim and 
tighten mounting bolts if needed. 

The machine must be level to be 
accurate. 

 

5.3 Mains connection 

Mains connection and any extension 
cords used must comply with 
applicable regulations. 

The mains voltage must comply with 
the information on the machine licence 
plate.  

The mains connection must have a  
10 A surge-proof fuse. 

Only use power cords marked H07RN-

Connections and repairs to the 
electrical equipment may only be 
carried out by qualified electricians.  

ATTENTION: 
- If the direction of rotation is not 
correct, the phase converter inside the 
CCE Euro plug must be pushed in and 
turned 180°. 

 

5.4 Initial lubrication 

The machine must be serviced at all 
lubrication points before it is placed 
into service! 
Failure to comply may cause serious 
damage. 
(see chapter 8 for lubrication) 

The coolant tank has to be filled with 
coolant. 

 

5.4 Starting operation 

Before starting the machine check 
the proper chucking. 

You can start the machine with the 
green ON-button (X, Fig 5).  

The red OFF-button (R) stops the 
machine. 

 

Fig 5 

The emergency stop button (Y) stops 
all machine functions. 

Attention:  

The machine still has electric power! 

Turn emergency stop button clockwise 
to reset. 

Use the variable speed select knob (V) 
to set the speed. 

The digital readout (U) shows the 
spindle speed. 

 

6.  Machine operation 

Always adjust the table and the depth 
stop to prevent drilling into the table or 
vise.  

Secure workpiece to the table with 
clamps or a vice to prevent rotating 
with the drill bit. 

T-slot size is 16mm. 

Feed the bit into the material with only 
enough force to allow the drill bit to 
work.  
Feeding too slowly may cause burning 
of the workpiece.  
Feeding too quickly may cause the 
motor to stop and/or the drill bit to 
break. 

Recommended speeds for a 10mm 
HSS drill: 

Wood:    

2000 RPM 

Plastic:    

1500 RPM 

Aluminium:  

1500 RPM 

Brass:    

1500 RPM 

Cast iron:  

1000 RPM 

Mild steel: 

 800 RPM 

High carbon steel:  

600 RPM 

Stainless steel:  

300 RPM 

Generally speaking, the smaller in 
relation the drill bit, the greater the 
RPM required. 

Wood requires higher speeds than 
metal.  
Metal is usually drilled at slower 
speeds; cutting oil is applied if 
necessary. 

 

Warning:

 

Always keep your hands well clear of 
the rotating bit. 

Never place your fingers in a position 
where they could contact any rotating 
tool, chuck or cutting chips. 

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

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

When using a drill press vice, always 
fasten it to the table. 

Never do any works 

“freehand” (hand-

holding the work piece rather than 
supporting it on the table), except 
when polishing. 

Support long workpieces with helping 
roller stands. 

Do not use wire wheels, router bits, 
shaper cutters, circle cutters, or rotary 
planers on this drill press.
