6 Cleaning, maintenance and repair
6.1 Cleaning
WARNING
Caution Unplug the electric supply cable.
▶ Unplug the electric supply cable from the power outlet and disconnect the
compressed air supply line.
WARNING
Caution Keep gripping surfaces clean and dry.
▶ Keep the machine, especially its grip surfaces, clean and free from oil and grease.
Do not use cleaning agents containing silicone.
Thorough, regular cleaning and maintenance of the equipment helps ensure smooth,
easy movement of moving parts and controls and protects the equipment from damage
caused by a build-up of slurry and dirt.
We recommend that the wire saw and pulley stands are cleaned quickly after each cut.
Pay particular attention to the running surfaces and the toothed rack on the guide rail as
well as all moving parts and operating controls.
Use plenty of water and a medium-hard brush to clean the entire system at the end of the
day, with the exception of the electrically powered components such as the compressor
and the control unit. Plan this cleaning work as part of your daily work schedule.
6.2 Care
WARNING
Caution Allow the machine to warm up before use at low temperatures.
▶ At temperatures below freezing, allow the machine to warm up slowly before
operation under load and blow all water out of the cooling system before long
pauses between use.
After cleaning, check that all parts are undamaged and that they operate smoothly, easily
and function correctly. Check that the drive unit, when under no load, can be moved
smoothly over its entire stroke with an air pressure of 1 bar. In the interest of avoiding
accidents and expensive consequential damage, damaged or incorrectly functioning
parts must be replaced before further use of the machine.
Spraying the cleaned machine with concrete form release agent reduces the amount of
dirt adhering to the surfaces and makes subsequent cleaning easier.
The air filters located at top right and on the floor inside the control unit should be
checked for cleanliness at regular intervals and replaced if necessary.
