STARTING UP
Before starting-up the tool ensure that:
- the packaging is complete and does not show signs of having been
damaged during storage or transport;
- the tool is complete; check that the number and type of components
comply with that reported in this instruction booklet;
- the power supply and socket outlet can support the load reported in the
table and that indicated on the tool identification plate reproduced and
explained on page 11.
ASSEMBLING THE TOOL
Assemble the handle (6) and auxiliary hand protection (12); these can be
positioned either on the left or right of the tool body.
MOUNTING THE VULCOFIX PAD AND BUFFER PAD
If working with machines (LH31N - LH32EN - LH232N):
1. Insert the vulcofix pad (8A) on the spindle (5) (fig. 1).
2. Insert the abrasive disc;
3. Screw on the tapered ring nut (7) and tighten it using the pin spanner,
preventing the spindle from moving using the 17 mm. spanner (fig. 2).
If working with machines (LH22N - LH22EN):
1. Screw the buffer pad (8) on the spindle (5).
2. Lock the spindle by pressing button (11), while at the same time
rotating the pad until it locks position.
WARNING: never press the button to lock the pad orpas until the tool
has stopped moving and is perfectly stationary; the gear box or the
push button pin could be broken and the guarantee would be
invalidated.
3. Firmly tighten the disk.
4. Unlock the spindle by releasing the button and rotate the disc pad by
hand to ensure that it runs freely.
BEFORE STARTING THE TOOL
Ensure that:
- the power supply conforms with the characteristics of the tool;
- the power supply cable and plug are in perfect condition;
- the ON/OFF switch works properly though with the power supply
disconnected;
- all the parts of the tool have been assembled in the proper manner and
that there are no signs of damage;
- the ventilation slots are not obstructed.
STARTING AND STOPPING
- Starting:move the switch lever (2) up; to lock it in "engaged" position,
move the switch block (3) forward towards the machine body.
- Stopping: : release the switch lever (2); if the switch is in "engaged"
position, move the switch lever (2) up in order to release the switch
block (3).
Warning! The tool continues to rotate after it is turned off.
Wait until it has come to a full stop before laying it down.
TEST RUN
Start the tool and check that there are no unusual vibration, no
dismatching of the buffer pad or of the abrasive disc.
Otherwise, switch-off the tool immediately and eliminate the cause.
ELECTRONIC SELECTING RPM (LH22EN - LH32EN)
The rpm can be adjusted by rotating the wheel (3). The choice of speed
depends on the characteristics of the abrasive disc and the material to be
worked.
