4-1. Selling Point Descriptions
4-1-1. Highest drilling speed and chipping performance in the class
The drilling speed of the Model DH 30PC2 is 1.3 times higher than C and equivalent to or higher than B thanks to
the efficient transmission of the hammering energy.
4-1-2. A highly reliable mechanism for prevention of idle hammering results in prolonged service life and
comfortable operation
Conventional mechanism for prevention of idle hammering is to open and close the air holes according to the
movement of the striker. The Model DH 30PC2 has air holes located at the position unaffected by the rebound of
the striker at no load. The air holes are opened and closed by the movement of slide sleeve (A) provided around
the cylinder that interlocks with the tool and the second hammer to prevent idle hammering. This mechanism
securely prevents idle hammering even if the striker rebounds heavily when drilling holes using a large-diameter
drill bit. Thanks to the highly reliable mechanism for prevention of idle hammering, the service life of the Model
DH 30PC2 is prolonged and hammering works requiring much attention not to break the surroundings can be
efficiently performed with the Model DH 30PC2.
4-1-3. Hitachi's original and convenient 3-mode changeover mechanism
The Model DH 30PC2 is equipped with Hitachi's original and new 3-mode changeover mechanism including the
mechanism for prevention of idle hammering. Thanks to this mechanism, operation is selectable from 3 modes,
"Rotation and hammering," "Rotation only" and "Hammering only." The Model DH 30PC2 can be widely used for
not only light-duty chipping works by means of a bull point but also cornering and grooving works by means of a
cold chisel and a cutter.

4-1-4. Shortest body in the class (entire length 355 mm)
The Model DH 30PC2 is equipped with Hitachi's original and new 3-mode changeover mechanism including the
mechanism for prevention of idle hammering. This mechanism made the entire length as short as possible to
355 mm. The Model DH 30PC2 has the shortest body in its class.

7. PRECAUTIONS IN SALES PROMOTION
In the interest of promoting the safest and most efficient use of the Model DH 30PC2 Rotary Hammer by all of our
customers, it is very important that at the time of sale the salesperson carefully ensures that the buyer seriously
recognizes the importance of the contents of the Handling Instructions, and fully understands the meaning of the
precautions listed on the Caution Plate attached to each tool.
7-1. Handling Instructions
Although every effort is made in each step of design, manufacture and inspection to provide protection against
safety hazards, the dangers inherent in the use of any electric power tool cannot be completely eliminated.
Accordingly, general precautions and suggestions for the use of electric power tools, and specific precautions and
suggestions for the use of the Rotary Hammer are listed in the Handling Instructions to enhance the safe, efficient
use of the tool by the customer. Salespersons must be thoroughly familiar with the contents of the Handling
Instructions to be able to offer appropriate guidance to the customer during sales promotion.
7-2. Caution Plate
The Model DH 30PC2 unit is provided with a Caution Plate (illustrated below) which lists basic safety precautions
in use. Carefully ensure that the customer fully understands and follows these precautions before using tool.

8. REFERENCE INFORMATION
8-1. Grease Replacement
The striking portion and the speed reduction portion of the Model DH 30PC2 respectively use different types of
grease. It is not necessary to replenish the grease unless the tool is disassembled for repair or there is grease
leakage due to a damaged seal. The striking portion uses special grease. To change the grease in the striking
portion (inside the crank case and cylinder case), carefully wipe the old grease off the parts, and re-lube with 30 g
(1 oz) into the crank case (connecting rod side) and 10 g (0.3 oz) into the cylinder case. Take care not to overfill
the grease as an excessive amount of grease can cause hammer failure.
The speed reduction portion (inside the gear cover) uses Hitachi Motor Grease No. 29. The proper supply volume
is 30 g (1 oz). Never use the striking portion special grease in the speed reduction portion. Special grease would
leak into the motor portion and cause subsequent trouble.
8-2. O-ring Replacement
The O-rings (mounted on the striker and piston) are extremely important to ensure adequate sealing of the air
pressure. Although the O-rings are made of special rubber to give them a long service life, they do nonetheless
become worn, and should be replaced by new ones periodically depending on frequency of use of the tool. With
average use, it is recommended that the O-rings be replaced at least every six months to ensure maximum
effectiveness.
8-3. Structure of the Model DH 30PC2 Rotary Hammer
Torque transmission
Armature revolution is transmitted to the second gear to rotate the bevel gear via the slip mechanism between
the second gear and bevel pinion axes. Rotation of the bevel gear is then transmitted to the cylinder keyed
thereto through the clutch. Cylinder rotation is conveyed to the retainer sleeve coupled together by means of
four needle pins and, then to the drill bit inserted into the retainer sleeve by way of two key rails and two steel
balls which couple them together.
Striking operation
The rotation of the armature is transferred to the crank shaft and connecting rod, which in turn cause the
piston to reciprocate inside the cylinder. As the piston reciprocates, the changing air pressure inside the air
chamber between the piston and the striker causes the striker to continuously strike against the end of the
second hammer. At the same time, the air-cushion effect within the air chamber absorbs the impact of the
striker. Should the air escape from the air chamber, the air-cushion effect would cease, and the impact energy
would not be absorbed. Accordingly, the O-rings mounted on the striker and the piston play an extremely
important role in sealing the air within the air chamber.

Mechanism to prevent idle hammering
When the working tool is released from the workpiece, slide sleeve (A) and the second hammer are forcibly
moved to the position illustrated in Fig. 4 by clutch spring, and the striker moves out of striking position. When
this occurs, the air holes located at the position unaffected by the rebound of the striker at no load are opened
and the pressure within the air chamber remains unchanged even though the piston continues to reciprocate,
thereby preventing striking operation.

Slip clutch mechanism
A clutch plate holding a steel ball is inserted between the second gear and the spring as a slip mechanism in
the Model DH 30PC2. If an excessively large torque is applied to the tool shaft, the second gear idles and
does not transmit rotation.
The slip torque is adjusted by the slip plate and the belleville (coned disk) spring pressure. With the
arrangement, the clutch slips when an excessive torque is applied to the working tool as when the drill bit
contacts steel bar/wire in the concrete, protecting the operator from unexpected motion of the side handle.
Sealing and dust-proof structure
The cylinder case and crank case section is tightly sealed with O-rings and oil seals as shown in Fig. 5. This
prevents leakage of grease from the cases, while also protecting them against dust from outside. The drill bit
chuck portion is protected by a rubber front cap to keep out dust and chips which could cause improper fitting
of the drill bit and/or other faulty operation of the chuck portion. The speed control switch is also a fully dustproofed type to prevent dust and chips from entering the handle section and causing possible operational
trouble or a break down of the insulation.

Speed control
The Model DH 30PC2 is equipped with a variable speed control switch which permits free change of the
rotation speed and hammering force. When drilling in fragile materials, pull the switch trigger gently for low
rotation speed (hammering force) to achieve optimum results.
Handle and side handle
The handle section is of a two-layer structure. The base is made of glassfiber-reinforced plastic and the
outside layer is soft resin. They are molded in one piece.
The side handle also has a two-layer structure. The base is made of glassfiber-reinforced plastic base with a
steel nut and the outside layer is soft resin. They are molded in one piece. The newly designed handle and
side handle structure ensures more comfortable grip for improved operability.

8-4. "Three-Mode" Changeover Mechanism
The change lever of the Model DH 30PC2 permits quick and easy changeover among the "Rotation and
hammering", "Rotation only" and "Hammering only" functions. Each function mode is explained below. When
operating the change lever, be sure to continue pressing the pushing button.
Rotation and hammering (Fig. 6)
Adjust the change lever to "Rotation and hammering" (
mark). Claws of the bevel gear engage with
matching claws of the clutch and rotation is transmitted to the cylinder coupled to the clutch. Thus the tool is
turned. When the tool is pressed against a workpiece, slide sleeve (A) blocks the air hole of the cylinder to
make an air chamber between the piston and the striker. The striker is then moved according to the pressure
fluctuation in the air chamber and transmits the hammering force to the second hammer and the tool.

Hammering only (Fig. 7)
Adjust the change lever to "Hammering only" (
mark). Engagement between the bevel gear and the clutch is
released and no rotation is transmitted. The spline inside the lock sleeve engages with the spline outside the
clutch to lock the turning motion of both the cylinder and the tool. When the tool is pressed against a
workpiece, slide sleeve (A) blocks the air hole of the cylinder to make an air chamber between the piston and
the striker. The striker is then moved according to the pressure fluctuation in the air chamber and transmits the
hammering force to the second hammer and the tool.

Rotation only (Fig. 8)
Adjust the change lever to "Rotation only" (
mark). Claws of the bevel gear engage with matching claws of
the clutch and rotation is transmitted to the cylinder coupled to the clutch. Thus the tool is turned.
When the lock sleeve is moved toward the tip, the amount of backward movement of slide sleeve (A) is limited
to the position where it contacts the lock sleeve to keep the air hole of the cylinder opened. Thus there is no
pressure fluctuation in the air chamber and no hammering force is transmitted.

Neutral (Fig. 9)
The Model DH 30PC2 has a neutral mode used for positioning a tool such as a cold chisel. Adjust the change
lever to "Neutral" (
mark). Engagement between the bevel gear and the clutch is released and no rotation is
transmitted. Then turn the grip of the tool retainer to adjust the tool to the desired position.

8-5. Caution when Using "Rotation Only"(No Hammering) Function
The chuck adapter and the drill chuck (optional accessories) are required for drilling into wood or metal materials.
The change lever of the Model DH 30PC2 permits changeover among "Rotation only," "Rotation and hammering"
and "Hammering only" functions. Be sure to adjust the change lever to "Rotation only" for drilling into wood or
metal materials by means of the chuck adapter and the drill chuck (optional accessories). If the change lever is
adjusted to "Rotation and hammering" or "Hammering only" for such operation, the drill chuck will be damaged by
hammering. Please caution the customers about the above.
--- 18 ---
8-6. Drill Bits
The chuck section is designed exclusively for the popular and widely available SDS-plus shank bits as shown in
Fig. 10. Rotating torque is transmitted to the drill bit by two key rails provided in the tool holding section. A steel
ball is used to prevent the bit from coming off.

The service life of a drill bit with a diameter of 8 mm is approximately 300 holes when drilling into concrete to a
depth of 30 mm. If reground before the end of its service life, the drill bit will continue to provide efficient drilling.

8-7. Tool Retainer
The tool retainer is structured as shown in Fig. 12. The tip of the tool retainer is covered with the front cap (made
of rubber) to prevent dust and chips from getting inside. The steel ball falls into the round groove of the bit to
prevent the tool from coming off and the two key rails transmit the rotation torque.
To mount the bit, push the bit in the tool retainer as far as it will go. Pushing lightly, turn the bit until it is caught.
At this position, slide the grip backward to the full. Release the grip. The grip is then returned to the original
position and the bit is fixed. Pull the bit to check whether it is securely fixed or not. To remove the bit, slide the grip
backward to the full and remove the bit.
