• Change hydraulic oil (HLP – 46, no.: 53649) every twelve months.
• To avoid malfunctions, regularly check the hydraulic unit for leaks, proper fit of connections
as well as the power cable for signs of damage or wear.
• Protect the fast-on couplings on both the hydraulic unit as well as the hydraulic hoses from
dirt and grime. Remove any dirt or foreign objects prior to connecting.
• The trimmer unit is equipped with two bi-directional blades. Rotate or replace blades
whenever trimming performance is no longer up to expectations.
• Always ensure that the pipe and workpiece ends, in particular the butt surfaces are clean.
Dirt or other foreign substances will shorten the serviceable life of the blades considerably
Pursuant to welding guidelines the welding machine must be inspected annually
by the manufacturer or an authorised service workshop. Machines subjected to
above average use or strain should be inspected at shorter intervals.
4.1 Machine and tool care
(Follow the maintenance instructions in item 4!)
Sharp and clean tools produce better work results and are safer.
Replace blunt, broken or lost parts immediately. Check whether the accessories are securely
connected to the machine.
Use only original spare parts from the manufacturer for maintenance work. Repairs must be
carried out only by professionally qualified personnel.
Disconnect the machine from the mains when it is not in use, prior to care and maintenance
work and before changing accessory parts.
Prior to reconnection to the mains, it must be ensured that the machine and the accessory tools
are switched off.
When extension cables are used, they must be checked for their safety and operativeness. Only
cables approved for outdoor use must be used.
Tools and machines whose housing or handles, especially those made of plastic, are cracked or
warped must not be used.
Dirt and moisture in such cracks conduct electric current. This can lead to an electric shock if the
insulation is damaged in the tools or in the machine.
Note: Furthermore, we refer to the accident prevention regulations.
