1. INTRODUCTION
This magnetic drill is designed for drilling holes in steel fabrication work. It is an ideal portable drilling solution equally suited for use in building
sites or the workshop environment and can be used to cut in horizontal, vertical and overhead positions.
The magnetic drill uses an annular hole cutter (sometimes called a slugger bit) to cut clean and accurate holes without pre-drilling or step drilling.
After cutting through the steel the cutter produces a "slug" (a cylindrical lump of steel) that falls from the centre of the cut.

4. SAFETY GUIDELINES
4.1 General Safety
Important: Ensure that you have read and understand the information contained in this manual before operating this equipment.
• This equipment is not intended for use by persons with reduced physical, sensory or mental capabilities. The equipment must not be
operated by children or by any persons who have not been instructed in the correct operation.
• Children and pets should be kept away from the working environment at all times during operation.
• Please read these instructions carefully and keep in a safe location for future reference. Ensure that the manual is passed on should
ownership of the equipment change at any time.
• Contact your nearest Jefferson Dealer for advice on correct usage, accessories (including compatible detergents), servicing and replacement
parts.
• Do not modify this equipment for any other purpose than those originally intended buy the manufacturer.
• Ensure that the product is used in accordance with the guidelines described in this manual. Failure to do so can result in personal injury and
may void the warranty.
• Ensure that you disconnect from the power supply before carrying out any adjustments maintenance or servicing on this equipment.
4.2 Working Environment
• Ensure that the working environment is kept clear and uncluttered. There should be plenty of light available for safe operation.
• Do not use this equipment in wet or windy conditions or damp or wet conditions.
• Do not use this equipment in the presence of ammable liquid or gases.
• Protect against electric shock by preventing contact with earthed or ground surfaces (e.g. pipes, radiators, cookers and refrigerators).
• We recommend using a suitable residual current device (RCD) for electrical safety when using this equipment.
• This equipment should be grounded while in use to protect the operator from electric shock.
• Store idle tools when not in use in a dry and secure location, out of reach of children.
• Do not force the tool during operation or use the equipment for a larger job than which it was designed.
4.3 Personal Protection Equipment (PPE)
• Do not wear loose clothing or jewellery during operation incase they get caught in moving parts.
• Wear protective hair covering to prevent long hair getting caught up in the tool.
• Ensure that suitable safety equipment is worn during use these include:
• Safety glasses
• Ear defenders
• Protective gloves
• Wear a hard hat (if working with magnetic drill above head height to prevent injury from ejected slugs after cutting). Use a face or dust mask if
cutting operations create dust. Non-slip, steel toecap footwear is recommended.
• Cutters are sharp. Wear gloves when installing or removing cutter from the arbor. Do not grab a rotating cutter.
• Keep tools sharp and clean for better and safer performance. Do not use dull or broken cutters.
• Follow safety instructions for lubricating and changing accessories (always check compatibility of annular cutters before use). Inspect tool
cords periodically and, if damaged, have them repaired by a qualied electrician or an authorised Jefferson Repair Centre.

5. OPERATION GUIDE
1. Make sure the workpiece is suitable for magnetic adhesion and that both the surface of the workpiece and that the magnetic base of the drill is
clean and free of dirt, grease and debris.
2. Secure the magnetic drill to the unit to workpiece with safety chain provided.
3. Position the drill by sliding it and gently feeding the arbor so that pilot pin is in contact with the centre of the hole you need to cut.
4. Activate the magnet by pressing the MAGNET button to the ON position.
5. Turn the Feed Handle, raising the annular cutter until the pilot pin is above the work surface.
6. Open the cutting uid valve.
8. Make certain that the annular cutter is clear of the workpiece and turn the motor on by pressing the MOTOR button to the ON position.
9. Feed the cutter slowly onto the workpiece. Carefully establish a cutting depth of about 1/16" before using the full force of the drill on the cut by
turning the feed handle to lower the arbor as required.
10. Ease up on feed pressure as the cutter starts to break through the workpiece.
11. When you have completed the cut, turn off the motor by pushing the motor button into the STOP position.
12. Turn feed handles to raise the arbor away from the hole. This will cause the slug to fall free (if it hasn’t already) so take care to ensure it does
not fall in a way that can cause bodily harm to the operator or any other persons in the vicinity.
13. Turn the MAGNET OFF by pushing the magnet button to the OFF position. As the magnet de-activates the base should lift up off the work
surface.
14. Disconnect the equipment from the power source.
15. Remove any chips or debris from the cutter and the magnet wearing a pair of protective working gloves and a set of pliers to protect your
hands from sharp materials.
16. Disconnect the safety chain and carefully remove the drill to complete the procedure.
6. CLEANING & MAINTENANCE
• 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 at 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 qualied 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.
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.
