SAFETY INSTRUCTIONS
As the following instructions cannot cover all possibly
occurring cases, sound common sense must be employed
when working with the hammer and in the vicinity of this
machine.
Do not touch the trigger until you are ready to operate.
Always hold the hammer with both hands while
operating.
Stay on a safe and stable platform while operating.
Do not put the hammer close to your face and do not
rest it on your leg.
Do not use your leg to push the hammer down while
operating. The tool can break and cause serious
injury.
Stand with your legs safe out of the way of the tool
while maintaining balance.
Compressed air is dangerous! Do not aim an air hose
at yourself or other people. Do not use pressurized air
to clean the site or your clothing.
Make sure all hose connections are firm and airtight
and secure hoses to prevent loss of air or injury if a
hose gets loose or bursts.
Secure hoses using the prescribed number of
recommended hose clips and sockets prescribed for
the type of hose.
Do not release any joints that are under pressure.
Always switch off the air supply and bleed hoses first.
3
Only operate the hammer
with recommended,
approved tools. Work with
the recommended air
pressure and avoid heavy
impacts.
Do not get distracted –risk
of accident is always
present.
Make sure there is no
plumbing or wiring
(electricity, gas, ...) in place
of operation.
If you come across a
foreign object while
operating, put the hammer
aside and uncover the
object carefully to identify
it.
If you cannot produce
sufficient thrust on the
hammer (e.g. while
operating horizontally or
upward), choose another
type of machine or
technology. Insufficient
thrust increases vibrations
and risk of injury.

MATERIAL AND CONSTRUCTION
Main parts of the hammer are constructed of SAE grade 11,
12 and 14 carbon steels. No materials susceptible to
ignition spark formation are used on external parts.
The hammer is also free of materials with hazardous
electrostatic charging properties. The galvanized steel
surface also meets all of the requirements above.
APPLICATION
The pick hammer is a versatile tool. It is designed for
breaking up low to medium strength rock and material
(concrete, bituminous roadways, coal etc.), in construction
works and mining or surface operations.
The SKA line is designed to reduce vibrations, putting less
stress on operator's hands.

TECHNICAL DESCRIPTION
The hammering section (cylinder, distribution and piston) is
slidably mounted to a controlling section (handle, nut, pipe)
and does not come into contact with hands of the operator.
A pneumatic and a mechanical springs are positioned
axially inbetween the controlling and hammering sections.
The two sections are prevented from relative rotation by a
pen and held together by a nut. Compressed air is in turns
filling spaces below and above a floating piston head in the
hammer cylinder, setting piston into linear reciprocating
motion. In power stroke, piston transfers its kinetic energy
to a tool that disrupts the material. Exhaust air leaves the
hammer through a series of holes in silencer. The silencer
can be rotated into arrested positions, directing the exhaust
air to ensure safety and comfort. The sliding mounting of
the cylinder to the handle and the two springs inbetween
prevent vibrations from transferring onto the handle in full
force. An integrated oiler ensures proper lubrication.
MODEL LABELLING
Machines are fitted with labels containing important
information. Keep these labels clean and readable at all
times and order new ones as necessary.
The main label should be found on the handle.
The 'CE' symbol states that the product is EC-approved
(see EC-Declaration of conformity).
Maximum permitted compressed air pressure is stated in
the top right corner.
The opened book symbol states that user has to read and
understand the manual before using the machine for the
first time.
The headset symbol reminds user to wear effective ear
defenders.
The last symbol reminds user to wear safety goggles.

Guaranteed noise level in accordance with Directive
2000/14/EC is indicated by a label under silencer, and a
mark on the silencer marks the group and category the
machinery falls under in accordance with Directive 94/9/EC
–ATEX.
MAINTENANCE PRINCIPLES
Only personnel properly acquainted with the structure and
function of the hammer can service the tool.
All repairs are to be performed by the manufacturer or
authorized trained personnel.
Dry, clear air of the appropriate overpressure
(see Technical data) must be available in
sufficient volumes.
Supply hose must match the prescribed dimensions.
To avoid excessive frictional pressure loss, do not use
hoses of over 15 meters in length (in case of a Js16
hose). If necessary, hose of a larger diameter can be
used over greater distances.
Protect the hammer from dirt and other harmful
particles getting in. Always keep the input and output
openings clean.
Blow the hose clear to get rid of potentially harmful
particles before attaching it to the hammer.
Properly tighten all joints and re-tighten after 3-5 hours
of first operation.
Check-up on the state of the hammer regularly.
Hexagonal chuck in SKA 12-D and 12-DZ makes use
of chisel type tools possible. The open screw retainer
can be used for wider chisels and facilitates faster tool
replacement. If the hammer operates without sufficient
thrust, the screw retainer can crack under heavy
impacts of the tool!
LUBRICATING
Lubricate the hammer properly to secure maximum service
life of sealing rings of the handle. Damaged rings let air
escape the handle body, limiting vibration dampening or
rendering it virtually ineffective. Sufficient lubrication is
secured with an oiler integrated in the handle. The oiler
needs to be re-filled before every work shift.
Alternatively, pour about 100 cm3of oil into the air supply
hose (at the entry point) by the compressor unit and 5 cm3
into the air inlet at the beginning of each work shift and
repeat every 2-3 hours of operating.
Thrust
With regards to vibrations
and manipulation of the
hammer, the optimal thrust is
between 150 –200 N.
The thrust must prevent the
hammer from working idly,
which increases wear and
chance of breakdown.
Tool insertion
Unscrew retainer with ring.
Always check the state of
rubber ring. Insert tool into
cylinder and screw retainer
back on.
The SKA 12-DZ version with
latch retainer comes without
a ring. Insert tool by tilting
the latch and then close the
retainer.
Never start a hammer
without a tool inserted!

SKA 12-B, D, DZ
Do not use hydraulic oils or unstabilized coleseed oils
for lubrication.
Before storing the tool for over three weeks, conserve
it using mineral oil (see Storing).
Do not use ecological oils for conservation.
Recommended ecological oils:
BP BIOHYD SE 46, ÖMV BIOHYD M 32,
TOTAL HYDROBIO 46, TopOil BIO UNI
Recommended mineral oils:
PARAMO PNEUMAT 46
STORING
Before storing the tool for over three weeks, it needs to be
conserved.
Conserve the hammer by pouring cca. 50 cm3(0.5 dcl)
of mineral oil into the air inlet and running it shortly to
coat its internal parts with oil.
Oil may leak from the oiler during prolonged storing.
Empty the oiler before storing.
Store the hammer in dry conditions –protected from
weather factors and relative humidity below 75%.
Do not store the hammer close to corrosive chemicals
or gases.
In proper storage conditions, the hammer can be stored for
a year and spare parts for a year and a half without re-
conservation.
DELIVERING
The hammer is delivered separately, including this manual
and a certificate of warranty.
By default, we deliver the ¾'' Quick Coupling as the joint
for the supply hose. Alternatively, the quick coupling can be
replaced by a cap nut with a socket, which can be attached
to the ¾“ threaded socket.
The cap nut (item no. 319 257) can be combined with:
Ø13 socket (item no. 319 264)
Ø16 socket (item no. 319 255)
Ø20 socket (item no. 319 256)
Low temperatures
Presence of condensate in
air coupled with low
temperatures can cause the
hammer to freeze up.
Add an AOV 6 water
separator or the SOOR unit
before the hammer and as
far away from the
compressor unit as possible
(min. 20 m).
Ordering spare parts
All hammers are
manufactured in accordance
with drawing documentation
to ensure interchangeability
of all components.
Please state the hammer
type, name, quantity and
item no. of the desired
component in your order
form.
