Operating tips

First, place annular cutter with ejector pin on a marked centre or marking. Drilling
with ALFRA Rotabest cutters does not require much expenditure of force. Set the
cutter and spot-drill, until the entire cut edge is formed as a circle.
During the drilling process, the cutter should be cooled permanently. Optimal Cooling
is possible by internal cooling with our coolant unit.
During the drilling process, do not Stop the motor. After the process, cutter draws
back with running motor.
Remove chips and core after each drilling. Remove chips with Chip-Remover – do
not touch with bare hands – DANGER OF INJURY!
Cleaning
Danger of injuries by unintentional switching on. Pull plug prior to cleaning.
Clean motor by means of dry compressed air (from the outside).
Check connecting lines on damages.
Clean and grease sliding surfaces regularly. Should, nevertheless, lateral play arise
by wear of the dovetail guide, this could be adjusted by adjusting the laterally
positioned set screw.
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.
