Excessive dust in the dust bag will reduce dust- collecting effectiveness. Remove dust from the dust bag regularly.
Remove the dust bag from the main unit, pull out the rail and throw away the dust and clean (see Fig. 12).

The hammer drill can be set to rotation only mode by rotating the change lever fully clockwise to the 
mark. (Fig. 15)
To drill wood or metal material using the drill chuck and chuck adapter (optional accessories), proceed as follows.

CAUTIONS:
◯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 hammer drill in addition.
◯Drill bits may snap off while withdrawing the hammer drill from the drilled hole. For withdrawing, it is important to use a pushing motion.
◯Do not attempt to drill anchor holes or holes in concrete with the machine set in the rotation only function.
◯Do not attempt to use the hammer drill 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.
6.When driving machine screws (Fig. 17)
First, insert the bit into the socket in the end of the 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.
CAUTIONS:
◯Exercise care not to excessively prolong driving time, otherwise, the screws may be damaged by excessive force.
◯Apply the hammer drill 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.
◯Do not attempt to use the hammer drill in the rotation and striking function with the chuck adapter and bit attached.
7.When driving wood screws (Fig. 17)

(2) Driving in wood screws
◯ 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.
◯ After rotating the hammer drill 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.
