♦ You may also use the drill chuck key to tighten the clamp.
Warning: Never use standard chucks in the
hammer-drilling mode
Selecting the Operating Mode (FIG. B)
The tool can be used in the following operating modes:
Rotary drilling: for screw driving and for drilling
into steel, wood and plastics
Hammer drilling: for concrete and masonry
drilling operations. Bit rotation: non-working
position used only to rotate a flat chisel into the
desired position
Hammering only: for light chipping and chiselling.
In this mode the tool can also be used as a lever to
free a jammed drill bit.
1. To select the operating mode, press the mode selector
button and rotate the mode selector switch (5) until it
points to the symbol of the required mode.
2. Release the mode selector button and check that the
mode selector switch is locked in place.
WARNING! Do not select the operating mode when
the tool is running.
Proper Hand Position (FIG. A, FIG. E)
WARNING! To reduce the risk of serious personal
injury, ALWAYS use proper hand position as shown.
WARNING! To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
sudden reaction.
Proper hand position requires one hand on the side handle
(9), with the other hand on the main handle (1).
Rotarydrilling(FIG.B,FIG.D,FIG.C1/C2)
♦ For drilling in steel, wood and plastics, or for screw
driving set the operating mode selector (5) to the
position.
♦ Fit the drill chuck assembly by referring to fitting drill
chuck part in this manual.
♦ Insert the appropriate bits. When driving slotted head
screws always use bits with a finder sleeve.
♦ For drilling in steel, wood and plastics, set the forward/
reverse lever(4) to the forward position(Fig C1). When
use for screw driver function, tighten screws set the
forward/reverse lever (4) to the forward position(Fig C1)
and loose screws set the forward/reverse lever (4) to
the reverse position(Fig C2).
WARNING! Never use drill chucks in the hammer drilling
mode.
Hammer drilling (FIG. B)
♦ For hammer drilling in masonry and concrete, set the
operating mode selector (5) to the position.
♦ The drill bit has to be placed accurately onto the drill
hole position. After that, pull the switch for optimal
effects. Make sure the tool is in the correct position to
prevent the drill from deviating from the hole.
♦ When the drill hole is clogged with debris or fine powder,
please don’t exert any more pressure. Tool should be
put in free-running state before removing part of the drill
bit from the hole. If repeated a few times, the blockage
in the hole would be cleared, and normal drilling can
resume.
WARNING! When the drill bit hits the steel rebar in the
cement, the tool may recoil dangerously. Please hold the
tool tightly in a balanced and stable position at all times to
prevent it from recoiling dangerously.
Safety Clutch
All rotary hammer are equipped with a safety clutch that
reduces the maximum torque reaction transmitted to the
operator in case of jamming of a drill bit. This feature also
prevents the gearing and electric motor from stalling. The
torque limiting clutch has been factory-set and cannot be
adjusted.
Chipping and chiselling (FIG. B)
♦ Set the mode selector switch (5) to the“hammering only”
position.
