SAFETY WARNINGS APPLICABLE TO POLISHING
OPERATIONS
If the use of an electrical tool in a damp area cannot be avoi-
ded, use a power supply fitted with a differential switch
(RCD).
This type of switch reduces the risk of electrical shocks
PARTS OF THE TOOL
1 - Identification plate
2 - ON/OFF switch
3 - Electronic speed control
4 - Disc pad fixing screw
5 - Disc pad Allen wrench
6 - Auxiliary handle (not supplied)
7 - Handle
8 - Buffer pad (not supplied)
9 - Handle fixing screws
10 - Velcro faced disc pad
11 - Motor ventilation slots
12 - Auxiliary protection (optional)
13 - Switch locking button (LHR 21E)
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
- Position the handle (7) on the gearbox such that the holes for
mounting the screws (9) are aligned with those on the gearbox.
MOUNTING THE DISC PAD
1. Place the disc pad (10) with the screw (4) in the centre (fig. 1);
2. slightly turn the disc pad (10) until it is fixed to the screw as in
fig 2;
3. tighten the screw using the supplied Allen wrench (5) (fig. 4).
Do not tighten the backing plate screw if it is in the wrong
position;
4. to remove, follow the same procedure in reverse order;
5. Assembre the buffer pad on the velcro surface of the pad.
ASSEMBLING THE BUFFER PAD
Press the buffer pad to attach it to the disc pad.
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 (LHR 15E)
- Starting: push the slide of the switch (2) forward; if the tool is to
be locked in the ON position, apply pressure to the front part of
the slide switch at the same time.
- Stopping: release the slide or, if locked in position, apply
pressure to the back part of the switch and allow it to return to
the stop position.
STARTING AND STOPPING (LHR 21E)
- Starting: push the lever of the switch (2) fowards the body of the
tool; if the tool is to be locked in the ON position, press button
(13) at the same time and keep it pressed while releasing lever
(2), thus locking the switch.
- Stopping: release the lever of the switch or, if locked in position,
push the lever to release the lock button.
TEST RUN
Start the tool and check that there are no unusual vibration, or no
dismatching of the buffer pad.
Otherwise switch-off the tool immediately and eliminate the
fault.
ELECTRONIC RPM REGULATION
The rpm can be adjusted by rotating the wheel (3). The choice of
speed depends on the characteristics of the buffers and the ma-
terial to be worked.
