CLEANING LIMESCALE
Over time, limescale deposits (mainly calcium carbonate) can build up in the motor’s cooling jacket, resulting
in less and less water flow as the limescale increases. If it is apparent that water flow through the motor is
reduced, descaling is necessary.
To descale the motor, prepare a 5% citric acid descaling solution. To make a 5% solution, add 50 g (30 ml) of
pure citric acid powder for every liter of water (16 tablespoons of powder to every gallon of water).
Using a portable pressurized water supply tank, pump the descaling solution into the motor and allow it to
soak for 15 minutes or so. After soaking, allow the remaining solution to circulate through the motor and
collect in a bucket. Repeat until the solution flows freely. Once descaled, allow fresh water to flow through the
motor for a few minutes to neutralize any acidity from the descaling solution.
Maintenance which should be performed by an authorized service center, include the following:
• Replace water seals as needed.
• Change the gear oil about every 100 hours of operation
• Replace the clutch discs and spring as needed.
If the replacement of the power supply cord is necessary, this has to be done by the manufacturer or
their agent in order to avoid a safety hazard.
WARNING: All repairs must be entrusted to an authorized service center. Incorrectly performed repairs
could lead to injury or death.
Do not throw electric power tools into the household waste! In accordance with the European Directive
2002/96/EG on Waste Electrical and Electronic Equipment and transposition into national law, used electric
power tools must be collected separately and recycled in an environmentally friendly manner.
