4 Maintenance
• Proper maintenance of the machine can extend the service life. Always keep tools and cables clean
(especially the air vents).
• The mixing tools should be cleaned when the process is complete or no use is planned for an extended
period of time. Normally, running water or silica sand can clean the mixing tools.
• Do not inflict mechanical stress on the machine during maintenance. This will inevitably damage the
stirrer.
• The hole of the hexagon socket must always be provided with a protective cover. The vent of the motor
housing cannot be covered during the operation of the machine and there must be no flammable
materials in the machine. The vent must be cleaned regularly
• Only original parts may be used in this machine.
• The carbon brush must be checked and maintained when the machine operation exceeds 60 hours. Please
change the brush in time when the brush is worn out.
• The handle switch must always be in perfect function and maintenance.
CAUTION
Unplug before cleaning.
