Maintenance

general

Regular maintenance is a fundamental prerequisit
for the machine to continue to be safe and efficient.
Do not use a machine that is due for regular
service. Rectify any defects found during regular
maintenance before clearing the machine for use.
Note! Maintenance must only be done by suitably
qualified and competent persons. Before
doing any maintenance, make sure that the
machine is safe and correctly sited on the
ground.

Every week

► Clean and inspect the machine.
► Grease the handle guides with Silicone (E-type
handles only).
► Check hoses and fittings for cracks or leaks.
Replace if necessary.
► Inspect the working tool for wear and damage.
Do not use an excessively worn or damaged
tool.
► Check generally for damage.
For the machine to maintain the specified
vibration values, this should always be
checked:
► Too big a clearance between the working 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. Use the gauge
that corresponds to the working tool's shank
dimension. If the gauge´s part (1) can be pushed
fully into the chisel bushing, the bushing is worn
out and must be replaced! See also "Checking
for wear" for checking the working tool's shank.

Safety and operating instructions
If it is possible to push the gauge to point A fully into
the chisel bushing (point B) then the chisel bushing or
fronthead should immediately be replaced.
► If the machine is equipped with vibration-
absorbing handles their function should be
checked.
► Check that the handles are moving freely (up
– down) and do not jam.
► Check that the springs are not damaged.

Every 3 months

► Check tightness of nuts, bolts, screws and hose
fittings.
► Check the chisel bushing in the nose for wear
and damage.

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.
