2. Safety instructions
for the use of drilling and breaking hammers with electric drive

2.1 General Instructions

2.1.1 Drilling and breaking hammers may only be operated by persons who

∗ are at least 18 years of age,
∗ are physically and mentally fit for this job,
∗ have been instructed in operating drilling and breaking hammers and

proven their ability for the job to the employer

∗ may be expected to carry out the job they are charged with carefully.

The persons must be assigned the job of operating drilling and
breaking hammers by the employer.

2.1.2 Drilling and breaking hammers are to be applied for their proper use.

Both the manufacturer’s operating instructions and these safety
instructions have to be observed.

2.1.3 The persons charged with the operation of these hammers have to be

made familiar with the necessary safety measures relating to the
machine. In case of extraordinary uses, the employer shall give the
necessary additional instructions.

2.1.4 It is possible that these drilling and breaking hammers exceed the

admissible sound level of 89 dB(A). Operators must wear personal
hearing protection if the admissible assessment sound level equals or
exceeds 89 dB (A).

2.2 Operation

2.2.1 The function of operation levers or elements is not to be influenced or

rendered ineffective.

2.2.2 Make sure that the machine is connected only to voltage and

frequency as indicated on its name plate. Choose correct cross section
for extension cord.

Safety instructions Drilling and breaking hammers

SV00046GB.fm 4

2.2.3 The operator has to switch off drilling and breaking hammers, to

disconnect them from the electric mains and to store them in such a
manner that they do not turn over be fore leaving the machines or

4. Description

4.1 Application

4.1.1 Wacker’s breaking hammer is commonly used in building construction,

civil engineering, facilities construction, municipal projects, concrete
plants, artificial stone plants, foundries, installation projects, and many
other applications. The breaking hammer is very well suited for
handling natural and artificial stone and every type of masonry and
concrete. Various quick-change tools facilitate chasing, chiseling,
breaking, digging, puddling, knocking, ramming, and deburring.

4.2 Putting into operation

4.2.1 Placing and removing of tool.

∗

Pull plug from electric socket.

∗

Snap out holder spring.

∗ Insert tool as far as it will go.
∗ Snap back holder spring.

Only use perfectly sharp tools with tool shank in perfect conditions. It
is advisable to lightly grease or oil tool shank and tool holder to avoid
dry running and premature excessive wear.

4.2.2 Connection

This electric hammer is powered by A. C. (single phase) (see technicla
data). A suitable plug is provided for connection.

4.3 During operation

4.3.1 Percussion rate and impact control

To reduce the power of the hammer turn knurling wheel in handle in
anti-clockwise direction (-). Turn wheel as far as it will go. To set
hammer to full power turn knurling wheel in clockwise direction (+).

Description

T00755GB.fm 10

4.3.2 Lock button

Lock control lever by means of lock button when using the hammer for
long breaking operations. When pression on control tongue, lock
button is released.

4.3.3 Handle system at tool holder (consisting of two handle pieces)

∗ Offset handle

Than handle can be turned perpendicularly to the tool shaft direction
and according to the application requirements by approx. 270o.
Loosen the adjusting ring for turning of handle. The handle can be
adjusted in 22,5o steps by tightening the adjusting ring.

∗ Radial handle

This handle can be screwed into either the additional handle or at the
side of the housing.

4.3.4 The complete handle system can additionally be turned by 360o,

perpendicularly to the tool shaft direction. It must be tightened with the
SW13 hex of the radial handle before starting any application (approx.
14 Nm).

4.4 Disassembly

4.4.1 Tool holder/Cylinder housing

emove pin. Remove supplementary handle with holder spring from tool
holder. Remove cheese head screws. Remove tool holder, tool holder
bush and damping sleeve. Remove cylinder housing from crankcase.
Remove percussion piston.

Description

T00755GB.fm 11

4.4.2 Crankcase

Access to rotor circlip: Remove screws, take bearing cover and crank
mechanism out of crankcase.

4.4.3 Disassembly of handle

Remove screws. Remove handle half and back handle.

4.4.4 Motor

Access to stator pack and rotor: Remove screws, remove bearing
bracket from crankcase. Remove stator pack. Then pull out O-ring and
air guiding bushing. Remove circlip and force out rotor.

4.5 Assembly

For assembly proceed in the reverse order to dismantling. The
following has to be observed in particular:

∗ All parts must be carefully cleaned and checked. Grease bearings,

crank mechanism and percussion system with special grease (see
technicla data).

∗ Clean front surfaces of cylinder housing and crankcase and seal with

Omni Visc, model 1002.

∗ Use Omnifit 230L to glue outer race of deep groove ball bearing.
∗ After completion of any kind of repairs, test-run with increasing load.

5.1 Maintenance schedule

5.2 Maintenance and lubrication

5.2.1 General instructions

Keep hammer and tools clean.

5.2.2 Mechanical part

∗ Every 20 hours of operation moderately grease crank mechanism and

percussion system via lubricating nipple situated on crankcase. Use
special grease (see technicla data).

∗ Check tool holder brushing for wear. The tool may have a play of max.

6 mm at a distance of approx. 200 mm from the entrance. If the
bushing is worn to a greater degree, replace it to avoid damages and
operational failures.

Malfunction

T01040GB.fm 13

6. Malfunction

6.1 Equipment failure

Cause Remedy

for 115V machines:
Input voltage to high (>150V) or to low (<45V)

Make sure to have the correct voltage.
Check extension cable for sufficient
conductor cross section

for 230V machines:
Input voltage to high (>300V) or to low
(<170V)

Let equipment cool off

Converter temperature to high

Check supply cable incl. clamp contacts
and replace if necessary.

Supply cable interruption Replace

Switch defect

Replace cable (incl. plug) with converter­switch repair set

Broken cable between converter and switch Replace converter

Defect the converter electronics

Replace cable (incl. plug) with converter­stator repair set

Broken cable between converter and stator Replace stator

Stator defect

* Let equipment run warm in warmer

environment (e.g. warm room)
* remove excessive grease from
percussion system
* replace defective components

Blocked percussion system:
* due to high grease resistance because of

low external termperatures

* due to over-greasing

* due to seizing of moving parts (e.g. due to
prolonged dry running)

Make sure to have the correct voltage.
Check extension cable for sufficient
conductor cross section
