1. PRODUCT NAME
Hitachi Hammer Drill, Model DH 45SA
2. MARKETING OBJECTIVE
There are four shank types in the 40 --- 50 mm market.
(1) Hexagon (13 mm ), (2) Hexagon (19 mm-Kango-), (3) SDS max, (4) Spline
The market tendency shows growth of the SDS max shank share, however, the hexagon (13 mm) shank retains
its No. 1 share in many markets because of economical accessory prices and compatibility with customer's
existing tools and accessories. Recently, demand for bigger dia. hole drilling is increasing year by year for
computer cable wiring and anchoring for earthquake-proof reinforcement work.
To meet market demand for a powerful, larger capacity Hammer Drill with hexagon (13 mm) shank, the Model
DH 45SA was developed as an advanced version of Model DH 40SA/YB.
The key features are as follows:
High performance, fast drilling speed: 80 % faster (at maximum) than DH 40SA/YB
Less fatigue, comfortable operation using the soft-grip & shock-absorbing handle
Other features (grease-packed lubrication, ergonomic exterior design)
3. APPLICA TIONS

(About 1.8 times faster than the Models DH 40SA/YB)
--- 3 ---
4-1. Selling Point Descriptions
4-1-1. Faster drilling speed
The drilling speed is 40 % faster than that of the Model DH 42, as the Model DH 45SA has greater striking energy
owing to the powerful motor and the total optimization of the rotation speed, striking frequency and the weight of
the striker.
4-1-2. Vibration-isolating handle reduces operator fatigue
The two vibration-isolating rubbers provided between the handle and the crank case, and also between the handle
and the housing efficiently absorb the vibration transmitted from the tool main body to minimize transmission of
vibration to the operator's arms.
4-1-3. Soft-touch handle and side handle
The double-layer molded handle and side handle consist of a plastic resin base covered with a soft plastic layer to
ensure a soft touch and easy grip of the handles.
4-1-4. Easy-to-use tool holder
The easy-to-grip tool holder allows the tool to be attached or removed simply by turning the grip.
4-1-5. Needle-pin type slip clutch
The Model DH 45SA is equipped with a needle-pin type slip clutch to ensure higher accuracy slip torque and
enhanced safety.

7. PRECAUTIONS IN SALES PROMOTION
In the interest of promoting the safest and most efficient use of the Model DH 45SA Hammer Drill 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 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 Hammer Drill 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.
8. REFERENCES
8-1. Grease Replacement Procedures
The electro-pneumatic hammering section and gear change section each use different kinds 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.
A special grease is used for the hammering section. To change the grease in the hammering section (cylinder
case and crank case), carefully wipe the old grease off the parts, and re-lube with 30 g in the cylinder case and
75 g in the crank case (on the connecting rod side). Take care not to overfill with grease as an excessive amount
of grease can cause hammering failure.
The gear change section (in the gear cover) uses grease No. 29 for power tools. Apply 40 g to the gear cover and
the gear portion in the crank case, and 20 g between the washer (A) of the slip clutch and the crank case. Do not
use the special grease used for the hammering section, or it will leak to the motor parts resulting in failure of the
tool.
8-2. O-Ring Replacement
The O-ring (attached to the striker and piston) plays an important role to ensure air tightness. Despite its
prolonged service life due to a special rubber material, it will inevitably wear out. Early replacement, preferably
once every six months, is recommended.

Rotation transmission
Rotation transmission is described with reference to Fig. 5. The gear arrangement of the DH 45SA has the
armature shaft positioned between the crank shaft and the bevel pinion shaft. Rotation of the armature shaft is
transmitted to the second gear through the first gear of the crank shaft and the second pinion. Then the
rotation is transmitted from the second gear through the slip mechanism disposed between the second gear
and the bevel pinion shaft to turn the bevel gear. The latter is keyed to the cylinder to rotate together. Cylinder
rotation is transmitted through the spline connection to the second hammer. Rotation is then transmitted to the
drill bit which is fitted into the hexagonal hole of the second hammer.
Hammering action
Armature rotation is transmitted to the crank and the connecting rod to reciprocally move the piston within the
cylinder. Air pressure developed between the piston and the striker changes as the piston moves. This causes
the striker to continuously hit the end face of the second hammer. Since the striker is moved under air
pressure, a certain air cushioning effect absorbs the striking shock.
If there is any leakage from the air chamber, the air cushioning effect becomes insufficient, resulting in an
incomplete shock absorbing effect. This is why the O-rings (attached to the striker and piston) for air tightness
are so important.

Arrangement against idle hammering
The DH 45SA is provided with an arrangement against idle hammering similar to that of the previous
DH 40SA. When the drill bit or bull point is moved off the concrete material, the second hammer is shifted
forward as indicated in Fig. 6 to change the striking position of the striker. This causes the air hole to open so
that air pressure within the air chamber no longer changes even with movement of the piston, bringing the
hammering action to a stop.

Slip mechanism
The slip mechanism structure is described below with reference to Fig. 7. The bevel pinion and the gear holder
are coupled together by the key and press-fitting. Spring (C) and needle pins are housed in elongated grooves
of the gear holder. The needle pin is pressed against the inner face of the second gear by spring (C) to allow
idle rotation of the second gear relative to the gear holder. When an excess torque is exerted on the bevel
pinion shaft, the needle pin is raised upon the projection of the second gear against the load of spring (C) to
allow idle rotation of the second gear. With this arrangement, the clutch slips when a violent torque is applied
to the tool as with the drill bit contacting steel wire within the concrete, protecting the operator from jerking or
being violently thrown around.

T ool holder
The tool holder is described below with reference to Fig. 8. As shown, three saddle keys are received in the
three respective elongated holes equidistantly located at the front cover. The cross sectional view A-A
illustrates the mode in which an end attachment tool is held in position. With the grip turned in direction A, the
saddle keys are shifted out of the holes to unlock the attachment tool from the tool body.
When fitting the attachment tool, turn the grip fully in the A direction, insert the tool shank deeply until it hits
against the hole end. Then, turning the grip fully in B direction causes the attachment tool to be securely held
in position. In contrast to the previous knob-retaining structure, the DH 45SA uses three saddle keys locked by
turning the grip, which are able to securely hold the tool with a minimized deflection of the drill bit or other
attachment tool.

Wiring connections
The wiring connections are shown in Fig. 9. The Model DH 45SA adopts a plug-in module type wiring system
consisting of plug (A) ass'y and plug (B) ass'y. The plug (A) ass'y connected with the internal wires of the
stator is fitted into the housing. The plug (B) ass'y is fitted into the handle section through the plug holder and
is connected with the switch terminal and cord. Wiring connection is completed when the housing section, the
handle and handle cover section are all assembled and then fastened together with screws. With such a
wiring structure, assembling and disassembling procedures associated with wiring connection have been
largely simplified over previous models.

Handle and side handle
The double-layer handle structure consists of a plastic base reinforced with glass fiber and an outer layer of
soft resin molded together with the base.
The side handle consists of a steel nut in the base and a hard plastic and a soft resin outer cover molded
together to form the handle. The DH 45SA thus uses the newly designed soft-touch handle and side handle
for easier handling of the tool.
Fluid-tight, dust-proof structure
The crank case and cylinder case are tightly sealed with three O-rings, an oil seal and a rubber seal as
indicated in Fig. 10. This prevents grease from leaking from inside as well as dust particles from getting inside
the tool.
The tool holder is also protected from dust with a rubber front cap and a dust cover.

(5) Carbon brush inspection
The motor employs auto-stop carbon brushes. When the carbon brushes near their wear limit, the current to
the motor is automatically interrupted and the motor stops. At that time, replace both carbon brushes with new
ones which have the same carbon brush number "74" as shown in Fig. 15. In addition, always keep the carbon
brushes clean and ensure that they slide freely within the brush holders.
9-3. Screw Lock TB 1401
Apply thread lock compound to all the M5 hexagon socket head bolts (except for M8 for front cover mounting and
M6 hexagon socket head bolts for cylinder case mounting, which are special bolts to be treated as service parts).
(Note) Be sure to apply thread lock compound to the threads during reassembly, as the bolts loosened with
vibrations may cause damage to the tool body .
