G
traditional ratcheting drill when drilling in concrete
This tool is designed for use in combination with all
G
standard SDS+ accessories

attention to the safety instructions at the back)
Avoid damage that can be caused by screws, nails and
G
other elements in your workpiece; remove them before
you start working
Always keep the cord away from moving parts of the tool
G
When you put away the tool, switch off the motor and
G
ensure that all moving parts have come to a complete
standstill
Use completely unrolled and safe extension cords with a
G
capacity of 16 Amps (UK 13 Amps)
In case of electrical or mechanical malfunction,
G
immediately switch off the tool and disconnect the plug
SKIL can assure flawless functioning of the tool only
G
when original accessories are used
Before using accessories always compare the maximum
G
allowed r.p.m. of that specific accessory with the r.p.m.
of the tool
This tool should not be used by people under the age of
G
16 years
Be careful not to drill or drive into areas where electrical
G
wires may be contacted; always use auxiliary
handle G 2
The noise level when working can exceed 85 dB(A);
G
wear ear protection
If the cord is damaged or cut through while working, do
G
not touch the cord, but immediately disconnect the plug
Never use tool when cord is damaged; have it replaced
G
by a qualified person
Always check that the supply voltage is the same as the
G
voltage indicated on the nameplate of the tool (tools with
a rating of 230V or 240V can also be connected to a
220V supply)
Be aware of the forces that occur as a result of jamming
G
(especially when drilling metals); always use auxiliary
handle G 2 and take a secure stance
Always disconnect plug from power source before
G
making any adjustment or changing any accessory
WHEN CONNECTING NEW 3-PIN PLUG (U.K. ONLY):
Do not connect the blue (= neutral) or brown (= live) wire
G
in the cord of this tool to the earth terminal of the plug
If for any reason the old plug is cut off the cord of this
G
tool, it must be disposed of safely and not left unattended
USE
On/Off 3
G
Switch locking for continuous use 4
G
Speed control for smooth starting 5
G
Changing direction of rotation 6
G
- when not properly set in left/right position, switch A
cannot be activated
! change direction of rotation only when tool is at a
complete standstill
Normal drilling/screwdriving versus hammer drilling 7
G
! select drilling function only when tool is switched
off
- for drilling in wood, metal and plastic as well as for
screwdriving the ring gear chuck and the corresponding
adapter should be used (see: Application Advice)
- the hammer mechanism is activated by applying a
slight pressure on the tool when the drill bit is in
contact with the workpiece
- best hammer drilling results can be obtained by only
a slight pressure on the tool needed to keep the
automatic clutch engaged; drilling performance will
not improve by applying more pressure on the tool:
SKIL LETS THE TOOL WORK FOR YOU
Changing bits 8
G
- clean and lightly lubricate accessory before insertion
- insert accessory in SDS+ chuck while turning and
push it until it engages (avoid damaging dust cap E);
the accessory locks in position automatically
- pull accessory to check that it is locked correctly
- remove accessory by pushing back locking sleeve F
! the SDS+ accessory requires freedom of
movement which causes eccentricity when tool is
off-load; however, the accessory automatically
centres itself during operation without affecting
drilling precision
! do not use bits with a damaged shank
Safety clutch
G
If the accessory gets jammed, the drive to the spindle is
interrupted (causing a rattling noise)
- immediately switch off tool
- remove the jammed accessory
- switch on tool again
Adjusting drilling depth 9
G
Holding and guiding the tool 0
G
! always use auxiliary handle G 2 (can be adjusted
with wing nut H)
- keep the ventilation slots uncovered
- do not apply too much pressure on the tool; let the
tool do the work for you
