SWITCHING ON AND OFF (Fig. 3)
• To switch the machine on, push the ON/ OFF button (b)
to the right and simultaneously push button (a) forward.
• To switch the machine off, push the ON/ OFF button (1)
backwards.
• While sanding, always make sure to hold the machine
firmly with both hands and ensure that you are standing
firmly on the ground. It is more secure to control the
machine with two hands.
• Apply only little pressure when sanding.
Applying too much pressure can result in uneven sanding.
• Choose the appropriate grain, depending on the state of
the surface and the material. Do not sand down for too
long on the same spot.
• Use finer sanding paper for the second round of sanding,
until you have reached the desired level of smoothness.
• To reduce the risk of injury, always disconnect the main
power plug before cleaning the device.
• Cle an your device with a damp cloth.
• For stubborn dirt, you can moisten the cloth with a mild
detergent or soft soap. Other cleaning products often
contain chemicals that can damage the plastic parts of the
device.
• Make sure that air vents always remain clean and open.
• Make sure that no liquids get into the machine and never
immerse the device in liquid.
• Repairs, inspections of the machine interior, adjustments,
and the replacement of carbon brushes should only be
performed by a qualified electrician. Only identical
replacement parts should be used. For more information,
please contact customer service.
• Disconnect the main power plug prior to performing any
maintenance work!
• Always keep the ventilation openings open and clean.
After each use, remove the dirt and dust with a paintbrush
or with compressed air from the ventilation openings.
• Never clean the sander with water or other liquids.
• If an increased brush sparking occurs, it is a sign that the
carbon brushes must be replaced. Have the carbon
brushes replaced by a professional.
The desired speed can be set with the speed control dial (2).
The appropriate speed depends on the material that will be
sanded and the sanding paper used and needs to be
determined through testing.
WARNING! When using the machine continuously, do not
run it on the lowest speed. This could cause overheating of
the motor.
The figures in the table below are advised values:
1-2 Low speed
3-4 Medium speed
5-6 High speed
Check the accessories prior to use. The accessories must
be perfectly mounted and be able to rotate freely. Let the
machine run without any load for at least 1 minute. Do not
use damaged, non-circular or vibrating accessories.
Damaged accessories can rupture and cause injuries.
Prior to removing the sanding sleeve: turn the sanding
sleeve counter-clockwise and at the same time pull it off the
shank.
All other kinds of accessories can be placed directly onto
the drive shaft, making the Maxx-Roll ready for use.
