Operating Tips; Maintenance And Repair - ALFRA ROTABEST 40 RL-E Bedienungsanleitung

Operating tips.

First, place annular cutter with ejector pin on a marked center 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 draw
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 screws (K).

the transport case in a lying position.
