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 mode with chuck adaptor (D) and bit attached.

5.Hammering only

Align the “ ” mark with the “ ” mark by rotating the change lever to set the “Hammering only” function. (Fig. 12)

(1) Mount the bull point or cold chisel.

6.When driving wood screws (Fig. 15)

(1)Selecting a suitable driver bit

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

(2)Tightening wood screws

Prior to tightening 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 in 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.

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.

7.Using depth gauge (Fig. 16)

(1)Loosen the knob on the side handle, and insert the depth gauge into the mounting hole on the side handle.

(2)Adjust the depth gauge position according to the depth of the hole and tighten the knob bolt securely.

8.How to use the drill bit (taper shank) and the taper shank adapter

(1)Mount the taper shank adapter to the rotary hammer. (Fig. 17)

(2)Mount the drill bit (taper shank) to the taper shank adapter. (Fig. 17)

(3)Turn the switch ON, and drill a hole to prescribed depth.

(4)To remove the drill bit (taper shank), insert the cotter into the slot of the taper shank adapter and strike the head of the cotter with a hammer supporting on the rest. (Fig. 18)
