CAUTION:

Application of force more than necessary will not only reducing drilling efficiency at all, but will deteriorate the tip edge of the drill bit and reduce the service life of the rotary hammer in addition.

Drill bit may snap off while disengaging the rotary hammer from the jammed hole. For disengaging, it is important to use a pushing motion or turn the drill bit counterclockwise.

Do not attempt to drill anchor holes or holes in concrete with the main unit in the rotation only function.

Do not attempt to use the rotary hammer in the rotation and striking function with the drill chuck and chuck adaptor attached. This would seriously shorten the service life of every components of the machine.

4.When driving machine screws (Fig. 9)

First, insert the bit into the socket in the end of chuck adaptor (D).

Next, mount chuck adaptor (D) on the main unit using procedures described in 6 (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:

Exercise care not to excessively prolong driving time, otherwise, the screws may be damaged by excessive force.

Apply the rotary hammer perpendicularly to the screw head when driving a 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 rotary hammer in the rotation and striking function with chuck adaptor (D) and bit attached.

5.When driving wood screws (Fig. 9)

(1) Selecting a suitable driver bit

Employ phillips screws, if possible, since the driver bit easily slips off the heads of slotted-head screws.

(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 rotary hammer at low speed for a while until a wood screw in partly driven into the wood, squeeze the trigger more strongly to obtain the optimum driving force.
