CAUTION:
Failure to use a dust collection bag will increase the presence of dust particles in the
work area. Continuous and prolonged exposure to high concentrations of dust may affect the
respiratory system.
5. OPERATION
5.1 SWITCHING THE WALL SANDER ON AND OFF
Ensure that the power supply voltage is identical to that shown on the sander nameplate. Also
ensure that the sander switch is in the OFF position. Connect the sander to the power supply.
The wall sander is equipped with a rocker switch. The lower end of the switch button is marked
OFF and the lower end is marked ON.
To start the sander: Push down the lower end of the switch (ON); to stop, push down the upper
end of the switch (OFF).
5.2 SPEED ADJUSTMENT
The speed of the sanding disc can be adjusted to suit different conditions and work requirements.
The wall sander is equipped with a variable speed controller. Speed is set by turning the control
knob. The control knob is numbered from "min" to "max", with "min" being the lowest speed.
(approx. 1000 rpm) and "max" being the highest speed {approx. 1850 rpm).
Use high speed settings for chip removal. Use lower speed to reduce removal rate for precise
control.
5.3 COAL REPLACEMENT
The sander is supplied with replacement brushes. When the brushes reach normal wear, replace
them with the spare parts supplied. Use a screwdriver to unscrew the carbon brush cover. Move
the tension spring to the side and remove the old brushes. Fit the new carbon brushes supplied
and carefully close the carbon brush cover with the screwdriver.
