Dear Customer!
The POLIRET TWIN is a powerful stainless steel polishing unit with two spindles and two
maintenance-free motors. Separate stainless steel spindle speed control. The comfortable
housing width enables working on both sides. Variable speed control 270 - 4.500 rpm –thus
speed is perfectly adapted to your requirements. The powerful brushless motors are
maintenance free and extremely durable. The POLIRET TWIN offers economic and precise
grinding, polishing, cleaning and brushing of metal and plastic material The integrated and
silent suction absorbs dust directly at the spindle. The textile filter bags are washable and
reusable. Closing one ventilation flap maximum suction power is achieved on the other side.
Since the exhaust air outlet is located on top of the housing the device can be placed directly
at a wall without losing suction power. Connection to an external central suction is not
provided, however it’s available on request.
Any other use or use beyond this is deemed improper. For resulting damage the
user/operator of this device is solely responsible.
Prior to installation of the device operating instructions and especially the safety instructions
must be read and followed by all personnel who use this device.
After having unpacked the device, please check carefully whether transportation damages of
any kind have occurred. If that is the case, the carrier or manufacturer must be notified within
3 days. The company will not be responsible for any damages found after that.
These operating instructions must be read and followed by all personnel who use this device.
To ensure quick access we recommend to keep it at a safe place near the device. In case of
loss it can be ordered from the manufacturer.
