7.0 Repair and maintenance
Warning
Always disconnect from the mains before starting repair or maintenance work.
After any repair, the unit must be checked by a qualified electrician (legal
requirement pursuant to VBG4 since 1.1.1990).
7.1 Daily maintenance
Check that no water is leaking out of the unit. This may impair the electrical safety of the unit and lead to
damage to the gearbox. In this case, please contact an authorised service centre.
Visual inspection for damage to the switches, the lines, or the plug sockets.
Clean the units after completion of the work.
Check that no water gets into the units during cleaning.
Drain the cooling water after using the machine. (Open the tap and blow out the water using compressed
air). This is particularly important in case of frost formation in winter.
7.2 Service after 120 operating hours
A service is due after 120 operating hours. The machine counts the operating hours itself and tells you
when 120 operating hours are reached by a blue LED on the handle. All worn parts are replaced during this
service. The next service is carried out at further intervals of 120 operating hours. The service interval may
be extended by max. 10 %, so you can complete your work with the machine at your own convenience.
If the maximun service interval of 120 + 12 operating hours is exceeded, the warranty becomes null and
void.
7.3 Quarterly
Have the cables, switches, plugs checked by a qualified specialist (provision pursuant to VBG4) and record
this. Replacing the gearbox oil significantly increases the service life of the gearbox.
8.0 Speed setting depending on cutting speed
The drive units of the Beluga series allow stepless speed adjustment. You can thus set the best cutting
speed for your saw blade or drill bit. This also provides a perfect, quick cut and the service life of the tool is
also significantly extended.
