•• When drilling hard metals, apply more force to the
power tool and lower the rotation speed.
In order to make switching between
the operation modes smoother, rotate
slightly chuck 1 (SDS PLUS) by hand.
•• When drilling large diameter holes in metal, first
drill a hole with a smaller diameter and ream it till the
necessary diameter (see. fig. 14.1).
Stepless speed adjustment
•• In order to avoid splitting of the surface at an exit
point of a drill bit when drilling holes in wood, follow the
instructions shown in figure 14.2.
Speed is controlled from 0 to maximum by
pressing force of on / off switch 10. Weak
pressing results in low revolutions, which
enable a smooth power tool switch-on.
Changing the rotational directions (see fig. 12)
•• When drilling holes in glazed ceramic tiles, in
order to improve the drill centering accuracy and to
save the glaze from damage, apply adhesive tape
to the presumed hole center and drill after that (see
fig. 15). Caution: drill tiles in the impactless drilling
operation mode only.
Change the direction of rotation only after
a full stop of the motor, acting otherwise
may cause damage to the power tool.
Power tool maintenance / preventive
measures
Clockwise rotation (drilling, fastening of screws) -
move the rotational direction switch 9 as it is shown
in fig. 12.1.
Before carrying out any works on the power tool it
must be disconnected from the mains.
Cleaning of the power tool
Counter
clockwise
rotation
(unscrewing
the
screws) - move the rotational direction switch 9 as it is
shown in fig. 12.2.
Safety clutch
An indispensable condition for a safe long-term
exploitation of the power tool is to keep it clean.
Regularly flush the power tool with compressed air
thought the ventilation slots 8.
After-sales service and application service
The safety clutch protects the power tool against
overload and damage in case of accessory sticking
during drilling.
Recommendations on the power tool
operation
Our after-sales service responds to your questions
concerning maintenance and repair of your product as
well as spare parts. Information about service centers,
parts diagrams and information about spare parts can
also be found under: www.crown-tools.com.
Wear thick soft gloves when working to
reduce vibration impact on your body.
Transportation of the power tools
•• Categorically not to drop any mechanical impact on
the packaging during transport.
•• Always use additional handle 6 when working, it will
ensure a better control of your power tool and reduce
recoil.
•• When unloading / loading is not allowed to use
any kind of technology that works on the principle of
clamping packaging.
•• At impact drilling the result does not depend on the
pressing force you apply to your power tool, which is
due to the impact mechanism design. This is why do
not exert excessive pressure on your power tool, as it
may result in borer seizing and motor overload.
Environmental protection
•• In order to decrease dust production when drilling
holes in walls and ceilings, take actions indicated in
fig. 13.
Recycle
raw
materials
instead
of
disposing as waste.
Caution: drill wood and metals in the
impactless drilling operation mode only.
•• Grease the drill bit regularly when drilling holes in
metals (except drilling non-ferrous metals and their
alloys).
Power tool, accessories and packaging should
be sorted for environment-friendly recycling.
The plastic components are labelled for categorized
recycling.
These instructions are printed on recycled paper
manufactured without chlorine.
