Useful Tips - Cotech Z1J-TD10-13E-UK Bedienungsanleitung

Hammer drilling or normal drilling
1. Stop the drill completely.
2. Set the selector switch (6) to the desired
drilling function. Select hammer drilling
for hard materials (concrete, stone, etc)
and normal drilling for steel, aluminium
and wood, etc.
Warning: Do not move the gear selector
unless the chuck is completely stationary.
Make sure that the control knob is in
the correct position by turning it until it stops.

Useful Tips

• Let the motor run for a few minutes without strain to cool the machine
after hard use.
• Use the side handle to help maintain full control when drilling.
• Only use sharp tools.
• For hard metal use titanium coated drill bits for concrete/tiles use tungsten
carbide drill tips. Read the instructions on the package!
• Fasten the workpiece down securely.
• Use clamps or vices when you can, this will leave you with both hands free
to manoeuvre the machine with, which increases precision.
• If you are drilling into thin materials it is important that you place a small piece of
waste material behind the hole to be drilled, otherwise there is a risk of burring.
• Hold the drill perpendicular to the workpiece before you start drilling (view 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 bit spin and lift it up after drilling through, it allows the machine
to cool down and the drill bit is freed of dust and wood chips.
