Maintenance And Service Instructions - stayer CD125 Manual De Instrucciones

The machine may only be used for dry cutting.
Always guide the machine with both handles.
Do not guide or carry the machine by the
elbow.
Adjust the cutting depth.
To compensate inaccuracies that occur when breaking
away the fin, the cutting depth must be set approx. 3 mm
deeper than the requested slot depth.
– Place the power tool in such a manner on both rear
chaser rollers 3, that the diamond cutting discs do not
touch the workpiece.
– Switch the machine on and slowly plunge into the
material.
– Guide the machine with both handles, applying moderate
feed, suited to the material being worked.
– The machine must always work in an upgrinding
motion. Otherwise, the danger exists of it being pushed
uncontrolled out of the cut.
– The machine can be both pushed or pulled in the cutting
direction. Vertical slots can easily be cut by pulling the
machine from top to bottom.
– After finishing the working procedure, swivel the diamond
cutting discs out of the slot with the machine still running.
– Switch the power tool off.
Do not brake coasting diamond cutting discs by applying
sideward pressure.
Never set down a coasting machine on the
chaser rollers 3, but always aside, so that the
diamond cutting discs can rotate freely and do
not face toward your body.
Diamond cutting discs become very hot during
operation; do not touch them until they have
cooled down.

Remove the remaining fin of the material with the break-
out tool 21.
Curved cuts are not possible, as the diamond cutting discs
could jam in the material.
When cutting through plate materials, ensure that the
materials are firmly backed on a surface or supported.
When breaking through walls, e. g. with a rotary hammer,
most of the chipping-off of the surface material can be
avoided by first cutting in a slot with maximum cutting
depth.
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, or
country-specific regulations.
These regulations are to be observed under all
circumstances.
Before beginning work, consult the responsible structural
engineer, architect or the construction supervisor. The
permitted slot depth and width depends on the slot length,
wall thickness and the building material used.

5. Maintenance and service instructions

Before any work on the machine itself, pull the
mains plug.
For safe and proper working, always keep the
machine and ventilation slots clean.
