1. Installation of dust cup (standard accessory) or dust collector (B) (Optional accessory) (Fig. 2, Fig. 3)

When using a rotary hammer for upward drilling operations attach a dust cup or dust collector (B) to collect dust or particles for easy operation.

○Installing the dust cup

Use the dust cup by attaching to the drill bit as shown in Fig. 2.

When using a bit which has big diameter, enlarge the center hole of the dust cup with this rotary hammer.

○Installing dust collector (B)

When using dust collector (B), insert dust collector (B) from the tip of the bit by aligning it to the groove on the grip. (Fig. 3)

CAUTION:

The dust cup and dust collector (B) are for exclusive use of concrete drilling work. Do not use them for wood or metal drilling work.

○Insert dust collector (B) completely into the chuck part of the main unit.

When turning the rotary hammer on while dust collector (B) is detached from a concrete surface, dust collector (B) will rotate together with the drill bit. Make sure to turn on the switch after pressing the dust cup on the concrete surface. (When using dust collector (B) attached to a drill bit that has more than 190 mm of overall length, dust collector (B) cannot touch the concrete surface but rotates. Therefore please use dust collector (B) by attaching to drill bits which have 166 mm, 160 mm, and 110 mm overall length.

○Dump particles after every two or three holes drilling.

○Please replace the drill bit after removing dust collector (B).

6. Selecting a driver bit

Screw heads or bits will be damaged should an inappropriate bit for the screw diameter be employed to drive in the screws.

HOW TO USE

CAUTION:

To prevent accidents, make sure to turn the switch off and disconnect the plug from the receptacle when the drill bits and other various parts are installed or removed. The power switch should also be turned off during a work break and after work.

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.

This rotary hammer can be set to rotation and striking mode by rotating the change lever (DH25PB only) fully counter-clockwise to mark. (Fig. 5)

(1) Mount the drill bit.

(2) Pull the trigger switch after applying the drill bit tip to the drilling position. (Fig. 6)

(3) Pushing the rotary hammer forcibly is not necessary at all. Pushing slightly so that drill dust comes out gradually is sufficient.

CAUTION:

When the drill bit touches a rebar, the bit will stop immediately and the rotary hammer will react to revolve. Therefore grip the side handle and handle tightly as shown in Fig. 6.

3. Rotation only (DH25PB)

The rotary hammer can be set to rotation only mode by rotating the change lever fully clockwise to mark. (Fig. 7)

To drill wood or metal material using the drill chuck and chuck adapter (optional accessory), carry out as follows.

Installing drill chuck and chuck adapter: (Fig. 8)

(1) Mount the drill chuck to the chuck adapter.

(2) The part of the SDS-plus shank is the same as the drill bit. Therefore, refer to the item of "Mounting the drill bit" for attaching it.

CAUTIONS:

○Application of force more than necessary will not only decelerate the working efficiency, but it will deteriorate the tip edge of the drill bit and reduce the service life of the rotary hammer as well.

○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 rotary hammer in the rotation and striking function with the drill chuck and chuck adapter attached. This would seriously shorten the service life of each component of the power tool.

4. When driving machine screws (Fig. 9)

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.

CAUTIONS:

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 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 rotary hammer in the rotation and striking function with the chuck adapter and bit attached.

5. When driving wood screws (Fig. 9)

(1) Selecting a suitable driver bit Recommended to employ cross-recessed screws, 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 recesses and gently drive the screws into the holes.

○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. Using the stopper (Fig.10)

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

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

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

(1) Mount the taper shank adapter to the rotary hammer. (Fig. 11)

(2) Mount the drill bit (taper shank) to the taper shank adapter. (Fig. 11)

(3) Turn the switch ON, and drill a hole in 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 manual hammer supporting on the rests. (Fig. 12)

HOW TO USE THE CORE BIT (FOR LIGHT LOAD)

When boring penetrating large holes use the core bit (for light loads). At that time use with the center pin and the core bit shank provided as optional accessories.

1. Mounting CAUTION

Be sure to turn power OFF and disconnect the plug from the receptacle.

(1) Mount the core bit to the core bit shank. (Fig. 13). Lubricate the thread of the core bit shank to facilitate disassembly.

(2) Mount the core bit to the rotary hammer (Fig. 14).

(3) Insert the center pin into the guide plate until it stops.

(4) Engage the guide plate with the core bit, and turn the guide plate to the left or the right so that it does not fall even if it faced downward. (Fig. 15).

2. How to bore (Fig. 16)

(1) Connect the plug to the power source.
(2) A spring is installed in the center pin.
Push it lightly to the wall or the floor perpendicularly. Connect the core bit tip flush to the surface and start operating.
(3) When boring about 5 mm in depth the position of the hole will be established. Bore after that removing the center pin and the guide plate from core bit.
(4) Application of excessive force will not only decelerate the working efficiency, but it will deteriorate the tip edge of the drill bit, resulting in reduced service life of the rotary hammer.

CAUTION

When removing the center pin and the guide plate, turn OFF the switch and disconnect the plug from the receptacle.

3. Dismounting (Fig. 17)

Remove the core bit shank from the rotary hammer and strike the head of the core bit shank strongly two or three times with a manual hammer holding the core bit, then the thread becomes loose and the core bit can be removed.

LUBRICATION

Low viscosity grease is applied to this rotary hammer so that it can be used for a long period without replacing the grease. Please contact the nearest authorized service center for grease replacement when any grease is leaking from a loosened screw.

Further use of the rotary hammer with incorrect grease will cause the machine inefficiency and reduce the service life.

CAUTION:

A special grease is used with this machine, therefore, the normal performance of the machine may be badly affected by use of other grease. Please be sure to let one of our authorized service center undertaking replacement of the grease.

MAINTENANCE AND INSPECTION

1. Inspecting the drill bits

Since use of a dull tool will cause motor malfunctioning and degraded efficiency, replace the drill bit with new ones or resharpen them without delay when abrasion is noted.

2. Inspecting the mounting screws:

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

3. Maintenance of the motor

The motor unit winding is the very "heart" of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

4. Inspecting the carbon brushes (Fig. 18)

The motor employs carbon brushes which are consumable parts. When they become worn to or near "wear limit", it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor will stop automatically.

At that time, replace both carbon brushes with new ones which have the same carbon brush numbers shown in Fig. 18.

In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

5. Replacing carbon brushes:

Disassemble the brush caps with a slotted-head screwdriver. The carbon brushes can then be easily removed.
