Operation
Speed Adjustment Wheel
Depending on the pressure applied at the ON/OFF trigger the machine
operates at a variable rotation speed of between 0 and 3000 rpm’s. Light
trigger pressure results in a low rotation speed and smooth controlled starting
of the drill.
The required rotation speed for drilling depends on the material being drilled. It
is best selected by a practical test. Always use a speed which is high enough
to prevent the machine from stopping due to overload. The speed can be
adjusted with the speed adjustment wheel (7).
Changing the Rotating Direction
The switch for clockwise/counter clockwise operation (5) should only be
operated when the motor is at a complete standstill. When the ON/OFF trigger
(6) is depressed, the switch for clockwise/counter clockwise operation (5) is
disengaged.
Clockwise Rotation for drilling, fastening of screws;
Counter Clockwise Rotation for removing screws.
Drilling/Hammer-Drilling
The drill/hammer-drilling selector (2) should only be operated when the motor
is at a complete standstill. The selector (2) is located on the top of the
machine.
For hammer-drilling push the switch towards the hammer symbol.
For drilling push the switch towards the drill symbol.
Maintenance and Cleaning
Always disconnect the drill from power supply before maintaining it.
Ensure that the ventilation slots are open and clean before each use.
Never clean the machine with water. Use a soft cloth to clean the housing.
Do not use aggressive chemicals or solvents to clean the machine as
these may damage the plastic case.
Enclosed in delivery you will find a pair of carbon brushes. If the machine
works powerlessly and sparking occurs at the brushes, it may be a sign
that the carbon brushes are used up and have to be replaced. Have the
carbon brushes replaced by a professional only or return the unit to the
Westfalia customer support department. Do not open the housing. Do not
try to repair it yourself.
