4. Electrical safety
The electric motor has been designed for one voltage only. Always check that the power supply corresponds to
the voltage on the rating plate.
This machine is double insulated in accordance with EN 60745 ; therefore no earth wire is required.
5. Work surface
Take care to avoid pointed projections and nails, etc.
This will wipe out the sandpaper and probably damage
the sponge pad as well.
OPERATION
1. Switching On and Off (Fig 5)
To switch on
:
- Hold the soft grip handle (
2
) or the front D-Handle (
1
) with one hand, and the main handle (
3
) with the other hand.
- Press the rocker switch (
10
) in position “
I
” (
ON
).
- Anticipate and be ready for the start up torque when the machine first starts.
To switch off
:
- Press the rocker switch (
10
) in position “
O
” (
OFF
).
CAUTION
: After the machine has been switched off, the sanding disc will still rotate for a time. Take care that parts
of your body do not come into contact with the disc and do not set the machine down while it is still rotating!
2. Selecting the speed (Fig 5)
This machine is equipped with a built-in electronic control circuit that can adjust and regulate the number of
rotations. Generally, you should use the higher speed for fast stock removal and the lower speed for more precise
control.
- Adjust the speed with the adjuster knob (
11
), depending upon the contents of operation: this can be done even
while the machine is running.
- The speed can be adjusted from the lowest speed 650rpm to full speed 1600rpm.
NOTE:
- If the tool is operated at low speeds for a long period of time, run the machine at the fastest speed for few ten
seconds when the work is finished in order to cool down the motor.
- If the tool is operated continuously at low speeds for a long period of time, the operation life of the motor will be
reduced.
- The speed adjusting dial can be turned only as far as full speed
Max
and lowest speed
Min
. Do not force to pass
full speed or lowest speed, or the speed adjusting function may no longer work.
3. Operation
- Effective control of this machine requires two-handed operation for maximum safety and control. Do not control
the machine’s head: hold the machine with both hands by using the two handles.
- It is vitally important to keep stable footing at all times, especially when standing on scaffolding or stilts.
- Before switching on the machine, keep the sanding head slightly away from the work surface.
- 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.
- Bring carefully the sanding head in contact with the work surface, as lightly as possible: just enough to keep the
sanding head flat against the surface.
- Do not over-press the machine in order to avoid overloading! Press with proper pressure for better grinding
effects.
- Make overlapping sweeps and keep the head in constant motion.
CAUTION
:
Never stop too long in the same place or there will be wave marks
.
- Good grinding effects and quality are mainly decided by choosing the right abrasive material. Ensure that the
sanding disc is suited to the task: coarse grit paper may remove material quickly, and fine grit paper may clog too
often and not shape down the surface.
- Once finishing the sanding task, switch off the machine.
