thrust pressure and on reaching the cutting depth, push it forward
against
the
direction of the arrow (14) because otherwise the cutting disc could lift uncon-
trolled out of the cut. Make sure that the diamond cutting disc does not twist/
jam. After cutting the workpiece, switch off the ROLLER’S Groove and wait
until the diamond cutting disc has come to a complete standstill. Do not lift off
the workpiece until the drive unit is at a standstill. Switch off the safety vacuum
cleaner/dust extractor.
CAUTION
Diamond cutting discs get very hot. Let them cool down before touching or
removing.
Make sure that the suction hose of the safety vacuum cleaner/dust extractor
does not kink and impair the dust extraction. Also make sure that no fragments
of stone or other objects jam in the suction nozzle (15) and/or suction hose.
Empty the dust bag of the safety vacuum cleaner/dust extractor early and clean/
renew the filter regularly. Observe the operating instructions of the safety vacuum
cleaner/dust extractor.

4. Maintenance
WARNING
Pull out the mains plug before doing maintenance work!
4.1. Maintenance
The gear of ROLLER’S Groove diamond slitting and cutting machines is
maintenance-free. It runs in a life-long grease filling and therefore needs no
lubrication. Keep the power tool and the mount of the diamond cutting discs
clean. Blow out the air vents on the motor from time to time with the machine
running. Clean plastic parts (e.g. housing) only with machine cleaner or a mild
soap and a damp cloth. Do not use household cleaners. These often contain
chemicals which can damage the plastic parts. Never use petrol, turpentine,
thinner or similar products for cleaning. Make sure that liquids never get inside
the electric power tool. Never immerse the power tool in liquid.
CAUTION
Check the diamond cutting discs regularly for cracks or damage. Cracked and/
or damaged diamond cutting discs may not be used.
