Care And Maintenance - Cocraft PRO IT1050-M Instruction Manual

• Hold the drill perpendicular to the workpiece before you start drilling (look from
several directions) make sure that you do not tilt the drill when drilling.
• Do not press too hard (so that the machine loses speed), let the tool do the job!
Reduce pressure just before the drill breaks through the material.
• Let the drill continue to run for a few seconds after drilling through the material and
withdraw the drill to allow the machine to cool down and the drill bit to be freed of
dust and wood chips.
Things to consider when drilling into wood and plastic
• For wood and other soft materials there are several types of tools, such as hole
saws and flat wood bits. Choose the tool most suitable for the work to be done.
Test the drill on a piece of waste material first.
• The tool can overheat if you don't pull it up often to free it of sawdust.
• Place a small piece of waste material behind the hole to be drilled before starting
to drill otherwise there is a risk of burring around the edges of the hole on
the back.
Things to consider when drilling into metal
• Mark the hole using a centre punch.
• The tool can overheat if you use the wrong speed. Use cooling liquid suitable for
your material e.g. methylated spirit for aluminium (cast iron and brass are cut dry).
• Use the lowest gear and a low speed for big holes.
• Be especially careful to secure of thin or sharp workpieces so that they do not come
loose, rotate with the drill bit and cause damage or injury; use a vice if possible.
Things to consider when drilling into concrete, tile or brick
• Use Tungsten carbide tipped drill bits.
• Use the hammer drill mode and work carefully, applying constant pressure.
• The material residue comes out of the drilled hole as powder or dust, wear
a dust mask.

Care and maintenance

• Always unplug the mains lead from the wall socket before cleaning or maintenance
of any sort.
• Check before use that the hammer drill, mains lead and plug are all undamaged.
Check that all the screws holding the housing together are tight.
• If the mains lead is damaged it must only be replaced by a qualified electrician.
• Make sure that the ventilation slots on the motor housing are clean and free from
contaminants.
• Clean the product using a lightly moistened cloth. Use only mild cleaning agents,
never solvents or corrosive chemicals.
• If the hammer drill is not to be used for an extended period, it should be unplugged
and stored in a dry and dust-free location out of reach of children.
