CAUTION
䡬
Application of force more than necessary will not
only expedite the work, but will deteriorate the tip
edge of the drill bit and reduce the service life of the
rotary hammer in addition.
䡬
Drill bits may snap off while withdrawing the rotary
hammer from the drilled hole. For withdrawing, it is
important to use a pushing motion.
䡬
Do not attempt to drill anchor holes or holes in
concrete with the machine set in the rotation only
function.
䡬
Do not attempt to use the rotary hammer in the
rotation and striking function with the drill chuck and
chuck adapter attached. This would seriously shorten
the service life of every component of the machine.
4. When driving machine screws (Fig. 10)
First, insert the bit into the socket in the end of chuck
adapter (D).
Next, mount chuck adapter (D) on the main unit
using procedures described in 4 (1), (2), (3), put the
tip of the bit in the slots in the head of the screw,
grasp the main unit and tighten the screw.
CAUTION
䡬
Exercise care not to excessively prolong driving time,
otherwise, the screws may be damaged by excessive
force.
䡬
Apply the rotary hammer perpendicularly to the screw
head when driving the screw; otherwise, the screw
head or bit will be damaged, or driving force will not
be fully transferred to the screw.
䡬
Do not attempt to use the rotary hammer in the
rotation and striking function with the chuck adapter
and bit attached.
5. When driving wood screws (Fig. 10)
(1) Selecting a suitable driver bit
Employ plus-head screws, if possible, since the driver
bit easily slips off the heads of minus-head screws.
(2) Driving in wood screws
䡬
Prior to driving in wood screws, make pilot holes
suitable for them in the wooden board. Apply the bit
to the screw head grooves and gently drive the screws
into the holes.
䡬
After rotating the rotary hammer at low speed for a
while until the wood screw is partly driven into the
wood, squeeze the trigger more strongly to obtain
the optimum driving force.
CAUTION
Exercise care in preparing a pilot hole suitable for the
wood screw taking the hardness of the wood into
consideration. Should the hole be excessively small
or shallow, requiring much power to drive the screw
into it, the thread of the wood screw may sometimes
be damaged.
6. Hammering only
This rotary hammer can be set to hammering only
mode by pressing the push button and turning the
change lever to the
mark (
Fig. 11
).
(1) Mount the bull point or cold chisel.
(2) Press the push button and set the change lever to
middle of
mark and
mark (
Fig. 12
).
The rotation is released, turn the grip and adjust the
cold chisel to desired position (
Fig. 13
).
