Troubleshooting checklist
Warning!
The compressed air supply must be
shut off or disconnected before
starting any work on the device.
Information
Suitable and recommended assembly
tools must be used for all
maintenance work on the device.
Information
Troubleshooting may only be done
by trained specialists.
Device not working or working intermittently
•
Clogged filter in the compressed air hose
connection.
►
Clean/change the filter.
•
Engine
dirty
as
a
result
of
poor-quality
compressed air (oil; water; dirt particles).
►
Disconnect the outlet hose and fill the air hose
with a little petroleum. Connect the device to the
compressed air supply until no more petroleum
comes out of the silencer. Repeat this process
multiple times if necessary.
•
Engine broken.
►
Engine must be overhauled.
Blade holder/detachable blade comes loose
during operations
•
Blade holder/detachable blade was not firmly
attached to the piston rod during assembly.
►
Reattach the blade holder/detachable blade and
check how far it slides into the assembly slot: the
clamping screw should be in the centre of the slot.
•
The clamping screw was not done up tightly
enough to the required 3 Nm.
►
Use the 3-Nm
torque wrench provided.
•
Drive piston bangs (audible as the device is
starting up or running).
►
If the piston only bangs
audibly once as the device is starting up then try
to pull the control lever a little more slowly.
►
If
the piston keeps banging while the device is
running then the engine must be overhauled
immediately
(engine
wear).
Device losing power
•
Clogged filter in the compressed air hose
connection.
►
Clean/change the filter.
•
System air pressure too low.
►
Test/set the air
pressure (6 bar dynamic).
•
Too much oil or condensation in the compressed
air.
►
Regulate the quantity of oil and/or filter out
the condensation.
•
Blade holder/detachable blade stuck or not
moving freely.
►
Depressurise the system and
check that the blade holder/detachable blade is
moving freely.
►
If the blade holder is not moving
freely, the plastic guide on the blade holder or the
blade holder guide on the handle should be
replaced.
►
If the detachable blade is not moving
freely, the blade holder guide on the handle must
be checked/replaced or the plastic blade guide
filed down using a fine sandpaper.
•
If the error has not been caused by the above, the
problem will be down to worn engine parts.
►
Engine
must
be
overhauled.
