controlled restarting of the machine after an
interruption in the power supply.
To restart the operation , switch the On/Off
switch to the Off position and start the ma-
chine again.
Note: Check the function of the restarting pro-
tection feature regularly by having the mains
plug pulled during operation and plugged in
again afterwards.
Working Advice
► Exercise caution when cutting slots in
structural walls; see Section “Informa-
tion on Structures”.
► Do not strain the machine so heavily
that it comes to a standstill.
► Clamp the workpiece if it does not re-
main stationary due to its own weight.
► The machine may only be used for dry
cutting.
►
Always guide the machine with both
handles. Do not guide or carry the ma-
chine by the elbow.
– Adjust the cutting depth, see section
“Pre-selecting the Cutting Depth”. To
compensate inaccuracies that occur when
breaking away the fin, the cutting depth
must be set approx. 3mm deeper than the
requested slot depth.
– Place the power tool in such a manner on
both rear chaser rollers, 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, ap-
plying moderate feed, suited to the materi-
al being worked.
– The machine must always work in an
up-grinding 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, but always aside, so
that the diamond cutting discs can ro-
tate 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 fi n of the material with
the break-out tool.
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 fi rmly backed on a sur-
face or supported.
When breaking through walls, e.g. with a rota-
ry hammer, most of the chipping-off of the sur-
face material can be avoided by fi rst cutting in
a slot with maximum cutting depth.
For cutting especially hard material, e.g., con-
crete with high pebble content, the diamond
cutting disc can overheat and become dam-
aged 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.
Noticeably 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.
Maintenance and Cleaning
► Before any work on the machine itself
(e. g. maintenance, tool change, etc.) as
well as during transport and storage,
remove the battery from the power tool.
There is danger of injury when unintention-
ally actuating the On / Off switch.
►
For safe and proper working, always
keep the machine and ventilation slots
clean.
When the battery is no longer operative,
please refer to an authorised after-sales ser-
vice agent for P.I.T. power tools.
Storage
► The specified storage period for the ma-
chine is 2 years.
► During the specifi ed period, store the ma-
chine at an ambient temperature of 0 ° C
to + 40 ° C and a relative humidity of no
more than 80%.
Transportation
To transport the product, use the original or
other packaging to prevent damage to the
instrument and its components during trans-
portation.
