Maintenance And Service; Maintenance And Cleaning - BTI WKS 125-2 Originalbetriebsanleitung

For cutting expecially hard material, e. g., concrete
with high pebble content, the diamond cutting disc
can overheat and become damaged as a result. This
is clearly indicated by circular sparking, rotating with
the diamond cutting disc.
In this case, interrupt the cutting process and allow
the diamond cutting disc to cool by running the
machine for a short time at maximum speed with no
load.
Noticeable decreasing work progress and circular
sparking are indications of a diamond cutting disc that
has become dull. Briefly cutting into abrasive material
(e. g. lime-sand brick) can resharpen the disc again.
Information on Structures
Slots in structural walls are subject to the Standard
DIN 1053 Part 1, or country-specific regulations.
These regulations are to be observed under all cir-
cumstances. Before beginning work, consult the
responsible structural engineer, architect or the con-
struction supervisor.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
In extreme conditions, always use dust
extraction as far as possible. Blow out venti-
lation slots frequently and install a residual
current device (RCD). When working metals,
conductive dust can settle in the interior of the
power tool. The total insulation of the power tool
can be impaired.
Please store and handle the accessory(-ies) carefully.
If the machine should fail despite the care taken in
manufacturing and testing procedures, repair should
be carried out by an after-sales service centre for BTI
power tools.

Switch on the
machine and place
the front part of the
cutting guide on the
workpiece. Slide the
machine with moder-
ate feed, adapted to
the material to be
worked.
In all correspondence and spare parts orders, please
always include the 7-digit order number given on the
nameplate of the machine.
Disposal
The machine, accessories and packaging should be
sorted for environmental-friendly recycling.
Do not dispose of power tools into household waste!
Only for EC countries:
According the European Guideline
2002/96/EC for Waste Electrical and
Electronic Equipment and its imple-
mentation into national right, power
tools that are no longer usable must be
collected separately and disposed of
in an environmentally correct manner.
Subject to change without notice.
