Care And Maintenance - CO/Tech Z1C-HW2-2600E Original Instructions Manual

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, flat wood bits, etc. Select the most suitable tool for the job. 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 a cooling fluid suitable
for your workpiece material e.g. methylated spirit for aluminium. (Cast iron and
brass do not require cooling fluid).
• Use low rpm for big holes.
• Be extra careful when clamping thin or sharp metal objects so that they do work
loose and cause damage or injury when they are drilling into. Hold workpieces in
a vice if possible.
Things to consider when drilling into concrete, tile or brick
• Use Tungsten carbide tipped drill bits.
• Use the rotary hammer drill mode and work carefully, applying constant pressure.
• The material residue comes out of the drilled hole as powder or dust.
Wear a face mask.
• Keep the chisels sharp and well sharpened.

Care and maintenance

• Unplug the lead before servicing.
• Before using the drill, make sure that all the screws are tightened. The heavy
vibrations when drilling and chiselling can cause screws to work loose.
• Store the instruction manual together with the rotary hammer drill.
• Make sure the drill's air vents are unclogged and free of dust at all times.
• Clean with a damp cloth when needed using only mild detergent. Never use
solvents or strong cleaning agents.
• Check that the red LED on the handle is not lit. If the LED is lit, it is time to
replace the brushes in the motor and the drill should be taken to a service centre.
