Important:
The magnetic strength of the drill base is related to the thickness of the steel ,or other ferrous
metal, in the workpiece. Magnetic adhesion can also be affected by the cleanliness of the metallic surface
you are fixing to. Material that is clean and free from coatings will offer the best surface for the magnet.
Factors that can reduce the effectiveness of the magnet and safe operation of the equipment include:
•
Coatings or paint layers on material
•
Material less than 3/8” thick
•
Workpieces with dirt, grease or debris between the magnet and the metallic surface
•
Curved or uneven work surfaces (The surface of the workpiece should be flat. For pipe applications, a pipe
adapter should be used.)
•
Workpieces that are smaller than the dimensions of the metallic base.
• Keep the machine, the cutter and electric cables clean from drilling debris.
• Always turn off the machine and unplug from the mains before carrying out any cleaning.
• Clean the motor by means of dry compressed air.
• Clean and grease any sliding surfaces regularly.
• Carbon brushes should be replaced after approximately 250 hours running time.
• When not in use the magnetic drilling machine should be stored securely in the transport case lying flat in a
dry storage space.
Note:
Excessive sparking may indicate the presence of dirt in the motor or worn out carbon brushes.
We recommend that you periodically check the brushes for wear and tear and replace them when they reach
6mm. Keep moving parts lubricated.
Maintenance, checks and repairs should only be made by qualified electricians or a Jefferson approved
technician. We recommend that the machine should be serviced after approximately 250 hours running time.
Only use genuine spare parts. A full list is available at the end of this manual. Contact your nearest
Jefferson dealer for further information.
