Safety and operating instructions
Before starting maintenance on the machine, clean
♦
it in order to avoid exposure to hazardous
substances. See "Dust and fume hazard".
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 the
nearest authorised workshop.
After each service, check that the machine's
♦
vibration level is normal. If not, contact the nearest
authorised workshop.
Every day
Before undertaking any maintenance or changing
the insertion tool on pneumatic machines, always
switch off the air supply and bleed the machine by
depressing the start and stop device. Then
disconnect the air hose from the machine.
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. Pay extra attention to leaks around the
Top cover. Ensure there is no air leaks around the
top cover, if so immediate action must be taken
to rectify before use.
Check that the air inlet nipple is tightened and that
♦
the claw coupling is free from damage.
Check regularly that the oil plug is tightened.
♦
Check that the O-ring on the oil plug is undamaged
♦
and that it closes tightly.
Check the threads in the machine lubricator and
♦
on the oil plug. Make sure they are not damaged
or worn out.

Too big clearance between the insertion tool's
♦
shank and the chisel bushing will generate
increased vibrations. To avoid getting exposed to
excessive vibrations, check the chisel bushing for
wear using the gauge that corresponds to the
insertion tool's shank dimension. If it is possible
to push the gauge (point A) fully into the chisel
bushing (to point B) then immediately replace the
chisel bushing. See also "Checking for wear on
the tool shank" for checking the insertion tool's
shank.
♦
Change damaged parts immediately.
♦
Replace worn components in good time.
♦
Make sure that all the attached and related
equipment, such as hoses, water separators and
lubricators are properly maintained.
Periodic maintenance
After each operating period of approximately 150
impact hours or twice a year the machine must be
dismantled and all parts be cleaned and checked.
This work must be performed by authorised staff who
are trained for this task.
