CAUTION:
To prevent accidents, make sure to turn the switch off and disconnect to the plug from the power receptacle.
Assembling the auxiliary side handle (Fig 1 & 2)
The auxiliary side handle (8) can be positioned on the right or left side of the machine.
- Simply tighten the side handle (8) by turning it.
Connecting the dust hose (Fig 3)
- Insert the hose (6) into the dust ejector (7) of the machine.
- The dust bag(5) is already connected to the hose.
- Make sure to empty and clean the dust bag in due time.
Installing/changing the sanding disc (Fig 4)
- Stick the sanding disc (14) on the sanding pad (13).
- Make sure the sanding disc is stuck properly and in a flat position.
- If you install a sanding disc with holes, please make sure they fit the holes on the sanding pad.
CAUTION:
Do not work without a sanding disc mounted on the sanding pad.
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 (10), 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 1200rpm to full speed 2000rpm.
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.
Switching On and Off (Fig 5)
- To start the machine, press the On/Off switch (11) and keep it pressed.
- To switch off the machine, release the On/Off switch (11).
- To work continuously, press the On/Off switch (11), then press the lock-on button (12). To switch off the machine,
press the On/Off switch (11) and then release it.
Adjusting air flow (Fig 6)
- Adjust the air flow by sliding the pressure plate (9):it will reduce or increase the suction power.
Operation
- Do not control the machine's head: hold the machine with both hands by using the two handles.
- Before switching on the machine, keep the sanding head slightly away from the work surface.
- 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.
