How to work with twist drills
•
The drill chuck with Weldon shank (art. no. 18107) is only to be used for drilling with twist drills up to
∅
10 mm.
•
Insert drill chuck with adaptor in the Weldon arbor (E).
•
Insert twist drill in drill chuck and tighten.
The motor can be continuously adjusted on the slide by releasing the Allan screw
(for a maximum enlargement of the stroke, when using twist drills and drill chucks).
Cleaning and care
Pull plug prior to cleaning to avoid injuries by unintentional switching on.
•
Clean the outside of the motor with dry compressed air.
•
Check connecting lines on damages.
•
Clean and grease sliding surfaces regularly. Should lateral play arise by wear of the dovetail guide this
can be adjusted by adjusting the laterally positioned set screws (K).
•
Carbon brushes should be replaced after appr. 250 hours running time.
•
After the work is finished we recommend to store the Metal Core Drilling Machine in the transport case in
a lying position.
