73/23/EEC Low Voltage Directive
89/336/EEC EMC Directive
93/68/EEC CE Marking Directive
WARNING! Ensure the drill is disconnected from the mains power supply before attempting any maintenance.
5.1. Cleaning
Keep drill ventilation slots clean and free from obstructions. At the end of work, thoroughly clean the air vents with a dry brush.
If available blow compressed air into the vents to clear any internal dust (safety goggles must be warn when undertaking this process).
Keep outer case of the drill clean and free from grease. DO NOT wash with water, solvents or use abrasives. Only wipe with a damp
soft cloth.
5.2. Lubrication
Keep the shanks of drill bits and chisels lightly lubricated. Periodically pull back the drill spindle lock and and apply grease to the outside
of the bit holder. (See fig.2-A) The internal mechanism is non-user serviceable. Where long term maintenance is required the drill
should be returned to your local Sealey dealer.
5.3. Changing carbon brushes
Periodically check the carbon brushes for wear. To access brushes remove the brush covers (fig.1-10) with a screw driver. Remove,
check and clean the brushes. If worn or damaged replace with new brushes. Contact your local Sealey dealer for details. Check that
brushes can move freely up and down within their carriers and replace covers (10).
5.4. OTHER
Any other service or maintenance must be carried out by your local Sealey service agent.
SDS850 - (1) - 13/03/03
Lock a pilot drill into the chuck (a smaller size drill than finished hole size, you may need to use standard chuck), and drill a pilot hole.
Insert the final sized bit into appropriate chuck or locking collar.
4.3.4. Plug drill into mains power. Hold drill firmly placing the bit at entrance of the pilot hole, or hole location mark and depress the trigger.
4.3.5. Move the drill bit into the work piece applying only enough pressure to keep the bit cutting.
DO NOT force the drill or apply side pressure to elongate the hole.
4.3.6. Great care must be taken when drilling plastic to avoid cracking the work piece.
4.3.7. If the bit jams in the work piece or if the drill stalls, release the trigger immediately. Remove the bit from the work piece and determine
the reason for jamming.
4.3.8. The depth gauge may be used to pre-determine the depth of hole.
4.4.
DRILLING METAL.
DO NOT use the hammer action when drilling metal.
4.4.1. Ensure drill is unplugged from the mains power supply.
4.4.2. If the material to be drilled is not fixed in place, it should be secured in a vice or with clamps to keep it from turning as the drill bit rotates.
4.4.3. Use a centre punch to mark desired hole location. This will prevent bit from slipping as you start to drill. Alternatively, drill a pilot hole
to assist the final drill size through the work piece. Lock a pilot drill into the chuck (a smaller size drill than finished hole size, you may
need to use standard chuck), and drill a pilot hole. Insert the final sized bit into appropriate chuck or locking collar.
4.4.4. When drilling metals, use a light oil on the drill bit to keep it from overheating. Oil will prolong life of bit and improve the drilling action.
If possible, place a wooden block under metal work piece at the point where the drill will break through.
4.4.5. Plug drill into mains power supply and hold drill firmly placing the bit at the entrance of the pilot hole.
4.4.6. Depress the trigger to start drill. Move the drill bit into the work piece applying only enough pressure to keep the bit cutting.
DO NOT force the drill or apply side pressure to elongate the hole.
4.4.7. If the bit jams in the work piece or if the drill stalls, release the trigger immediately. Remove the bit from the work piece and determine
the reason for jamming.
4.4.8. The depth gauge may be used to pre-determine the depth of hole.
4.5.
