DISMOUNTING THE BRUSH-HOLDER OR WHEEL-HOLDER FROM THE UNIT SHAFT
The unit comes with two extractors (A) which enable brush-holders or wheel-holders to be removed
easily. Grip the handle of the extractor firmly and turn it anti-clockwise on the right-hand end of the shaft
or clockwise on the left-hand end. The pressure exerted by the extractor as it advances will smoothly
release the brush-holder or wheel-holder.

CONDITIONS OF USE

For best results use the unit as follows:
• Mount an appropriate brush-holder/wheel-holder as indicated above.
• Connect the unit to a 230 V, 50-60 Hz power source.
• On the R-080160 polisher, select the desired spin speed (1500/3000 rpm) via switch D.
• On the R-080150 polisher, switch on the main switch to start up the motor.
• Before polishing or grinding a workpiece, check the motor spin direction, as the initial workpiece
attack angle depends on this. Incorrect attack angles can be extremely dangerous.
• The following protective equipment is recommended for polishing or grind-ing:
- safety goggles;
- safety gauntlets;
- face-mask;
- proper exhausters;
- a protective screen suited to the characteristics and shape of the unit. TALLERES
MESTRAITUA, S.L. recommends R-080200 or R-080210 screens, which are especially
designed for use with R-080150 and R-080160 polishers.
• After using the unit, clean the inside of the protective screen.

MAINTENANCE AND CLEANING

To ensure a long, trouble-free useful life for your unit, proceed as follows:
• After using the unit, clean dust off the inside of the protective screen with a brush. Clean the whole
screen regularly with a cloth moistened in soapy water.
• To clean the motor and base used a cloth moistened in soapy water. Never use alcohol, solvents or
other inflammable liquids.
• Never immerse the unit in any liquid.
• If you notice unusual noises or vibrations, send the unit to your technical assistance service.
• This unit is designed to work correctly on the four suction caps on base G.
PRECAUTIONS
♦ Before connecting the unit to the mains, check that the power supply is 230 V, 50/60 Hz.
♦ Discard any cracked or damaged brush or grinding wheel: if these elements break during operation
they could cause serious accidents.
♦ Before starting work, ensure that the brush-holder/wheel holder is firmly attached to the motor shaft.
♦ When handling workpieces, use safety goggles, gauntlets, a face mask and a suitable safety screen.
We recommend MESTRA R-080200 or R-080210 screens.
♦ Do not allow children or unskilled personnel to handle the unit.
♦ If the motor shaft locks during normal operation, disconnect the unit from the mains before attempting
to release it by turning it manually.
♦ Never polish, brush or grind materials which may give off particles which are toxic if inhaled.
