When taking a break
♦
During all breaks you must place the machine in
such a way that there is no risk for it to be
unintentionally started. Make sure to place the
machine on the ground, so that it can not fall.
♦
In the event of a longer break or when leaving the
workplace: Switch off the power supply and then
bleed the machine by activating the start and stop
device.
Maintenance
Regular maintenance is a basic requirement for the
continued safe and efficient use of the machine.
Follow the maintenance instructions carefully.
♦
Before starting maintenance on the machine, clean
it in order to avoid exposure to hazardous
substances. See "Dust and fume hazards"
♦
Use only authorised parts. Any damage or
malfunction caused by the use of unauthorised
parts is not covered by warranty or product liability.
♦
When cleaning mechanical parts with solvent,
comply with appropriate health and safety
regulations and ensure there is satisfactory
ventilation.
♦
For major service of the machine, contact your
nearest authorised workshop.
♦
After each service, check that the machine's
vibration level is normal. If not, contact your
nearest authorised workshop.
Every day
♦
Clean and inspect the machine and its functions
each day before the work commences.
♦
Check the tool retainer for wear and function.
♦
Conduct a general inspection for leaks and
damage and wear.
♦
For the machine to maintain the specified vibration
values, always check the following:
Too big a clearance between the insertion tool's
shank and the chisel bushing will generate
increased vibrations. To avoid exposure to
excessive vibrations, check the chisel bushing for
wear every day.
♦
Check that the handle is moving freely (up and
down) and does not jam.

Original instructions
Safety and operating instructions
Change damaged parts immediately.
♦
Replace damaged and worn components in good
♦
time.
Make sure that all the attached and related
♦
equipment, such as hoses and flow dividers are
properly maintained.
Every week
♦
Check that the springs are not damaged.
Every three month
♦
Check tightness of nuts, bolts, screws and hose
fittings. When retightening see the correct torque
settings in the spare part list.
♦
Check the bushing in the nose for wear and
damage.
♦
If the breaker is equipped with Ergonomic handles
check the adjustment of the handles. When the
trigger lever is pressed fully down you should be
able to move the trigger pawl (with a screwdriver)
approximately 1 millimetre further.
Every 600 hours of operation
or every year
♦
Check moving parts, seals and bolts for wear and
cracks. Replace if necessary.
♦
Check the function of the machine.
Storage
♦
Disconnect the machine's hoses from the power
source, see "Start and stop".
♦
Make sure that the machine is properly cleaned
before storage.
♦
In case of long-term storage, the striking piston
must be protected against corrosion. This is done
by pushing it (through the bushing) to its upper
position while the machine is placed up-side-down.
As the quick-release couplings are blocked when
disconnected, the striking piston must be pushed
upwards with the hoses mounted but the power
pack inactivated.
♦
Store the machine in a dry place.
