8 OPERATION
Always hold the drywall sander with both hands! Keep your hands away
from the sanding head. Otherwise, your hand could become caught, as the
sanding head swivels in different directions.
▪
Attach sanding pad.
▪
Attach sanding tool.
▪
Set power tool to the required length.
▪
Connect dust extraction system.
▪
Insert mains plug.
▪
Switch on the device.
▪
Press the drywall sander gently against the work surface (the pressure should be just
enough to ensure that the sanding head is flush with the work surface).
8.1
Starting and stopping tool
Make sure that the power circuit voltage is the same as that shown on the specification plate
of the machine and that switch (9
) is “OFF” before connecting the tool to the power circuit.
8.2
Switching the machine on and off
Turn on/off the drywall sander by switch.
8.3
Adjusting the rotation speed (Fig. 7)
The speed of the machine is variable to suit different tasks. It can be adjusted from 600 min
-1
up to 2600 min
-1
by using the thumb wheel (10). Turn in the counter clockwise direction to
increase the speed and in the clockwise direction to decrease the speed. Generally, you
should use the higher speed for fast stock removal and the lower speed for more precise
control.
8.4
Constant speed (Fig. 8)
Keep the machine running at the same speed a selected. Do not overload by excessive
pressure.
9 SANDING OPERATIONS
Once the machine and vacuum cleaner are set up and all safety measures and equipment are
in place, begin by turning on the vacuum cleaner and then the machine. (If you are using a
vacuum cleaner with integrated switching, then simply turn the machine on.)
9.1
Round sanding head (Fig. 9)
▪
Begin sanding and carefully contact the work surface as lightly as possible-just enough to
keep the sanding head flat against the surface.
▪
The pivot point in the sanding head allow the sanding disc (7) to follow the contours of the
work surface.
▪
The best technique is to use overlapping sweeps and keep the head in constant motion.
Never stop too long in any one place or there will be swirl marks. With experience it will be
very easy to create excellent results.
9.2
Polish the ceiling (Fig. 10)
Put the rubber band into the pothook to fix the head. Keep the sanding pad and handle
vertical, keep the sanding pad and ceiling in the same level. Then you can use to sand the
ceiling.
