Screwdriving
You can fit screwdriver bits directly into the drill chuck. For
best results use Phillips screws. Safe working is made
possible by the self-centring feature. Please be sure that
you also use the correct screwdriver bits.
Important note for machines with clockwise and anti-
clockwise rotation.
Caution!
Always disconnect the mains plug before removing and
fitting the drill chuck.
The chuck is tightened with a turning moment of 30 Nm.
Only this guarantees that the chuck is not unintentionally
unwound from the drill spindle in anticlockwise mode.
Should the chuck be undone from the drill spindle for the
purpose of replacement, the new chuck must be tightened
with a turning moment of at least 30 Nm before the ma-
chine is used again.
The plane surfaces of the chuck and drill spindle must be
cleaned before a new chuck is mounted.
Caution!
When turning anticlockwise, it is possible that the
chuck loosens itself from the spindle. For this reason
make sure that the chuck sits properly on the spindle.
Always make sure that the chosen speed is correct for
the purpose for which you are using the machine.
High speeds are necessary for polishing and grinding.
When drilling match speed with type of material and drill.
High speed drilling in steel and stone will cause premature
tool wear.
Use tool steel twist drills for soft materials such as wood
and plastics; carbide-tipped stone drills for stone and con-
crete; high speed twist drills for steel and iron.
Also make sure that, when using a gear-rim-chuck, the
drill chuck key is never fastened to the drill with chains,
strings or by similar means. Be sure that the workpiece
cannot be taken along by the drill.
Maintenance
The machine's motor has life-time lubrication and requires
no special maintenance. However, should you operate the
machine on a continuous basis over long periods of time
we recommend that you send us the machine for thorough
cleaning and an inspection. This will spare you unnecess-
ary repair expenses and increase the machine's service
life. If you always clean the ventilator of dust after each
operation, the motor will enjoy an ever longer service life.
Uniform ventilation is essential for a long service life.
Replacing carbon brushes
Our service personnel will do this and all other servicing
work fast and professionally.
Mains cable
Damaged mains cables must not be used. They must be
replaced without delay by an authorised servicing agent.
