1. Switch operation The rotation speed of the drill bit can be controlled steplessly by varying the amount that the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the switch is pulled more. To turn the switch OFF, release the trigger switch to its original position. 2. Rotation + Striking This rotary hammer can be set to rotation and striking mode by pressing the push button and Fig. 6 turning the change lever to mark. (Fig. 6) (1) Mount the drill bit. (2) Pull the trigger switch after applying the drill bit tip to the drilling position. (Fig. 7) (3) Pushing the rotary hammer forcibly is not necessary at all. Pushing slightly so that drill dust comes out gradually is just sufficient. Fig. 7 CAUTION: . When the drill bit touches an iron reinforcing rod, the bit will stop immediately and the rotary hammer will react to revolve. Therefore please grip the side handle and handle tightly as shown in Fig. 7. Change Lever Push Button English 3. Rotation only Push Button This rotary hammer can be set to rotation only mode by pressing the push button and turning the change lever to mark. (Fig. 8) To drill a wood or metal material using the separately sold drill chuck and chuck adaptor, proceed as follows. Installing drill chuck and chuck adaptor: (Fig. 9) (1) Mount the drill chuck to the chuck adaptor. (2) The part of the SDS-plus shank is the Front Cap Grip same as the drill bit. Therefore, refer to the item of “Mounting the drill bit” for attaching it. Chuck Adaptor Fig. 9 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. 10) Socket First, insert the bit into the socket in the end of chuck adaptor (D). Next, mount chuck adaptor (D) on the Chuck Adaptor (D) main unit using procedures described in 5 (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. Change Lever Fig. 8 Part of SDS-plus ShankDrill Chuck Bit Front Cap Grip Fig. 10 English 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. 10) (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. 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. Striking only This rotary hammer can be set to striking only mode by pressing the push button and turning the change lever to 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) Then rotation is released, turn the grip Change Lever and adjust the cold chisel to desired position. (Fig. 13) (3) Turn the change lever to mark. (Fig. 11) Then bull point or cold chisel is locked. Change Lever Push Button Fig. 11 Push Button Fig. 12 English 7. Using depth gauge (Fig. 14) (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 adaptor (1) Mount the taper shank adaptor to the rotary hammer. (Fig. 15) (2) Mount the drill bit (taper shank) to the taper shank adaptor. (Fig. 15) (3) Turn the switch ON, and drill...
