Operation - Sparky Group EX 150E Original Instructions Manual

Operation

These power tools are supplied from single-phase al-
ternating current mains only. They are double insulated
according to EN 60745-1 and IEC 60745 and can be
connected to grounded or not grounded sockets. This
power tool is radio suppressed in compliance with EMC
Directive.
This power tool is designed for sanding and polish-
ing flat and convex metal, plastics and wood surfaces.
The speed can be adjusted smoothly in a wide range to
achieve optimum operation mode for different materials.
PRIOR TO INITIALOPERATION
▪ Make sure the power supply voltage corresponds to
the value indicated on the name plate with technical
data of the tool.
▪ Always check the position of ON/OFF switch. The
power tool must be connected to the power supply
socket only when this switch is in OFF position. If the
plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.
▪ Make sure that the cord and the plug are in order. If the
replacement of the supply cord is necessary, this has
to be done by the manu-facturer or his agent in order
to avoid a safety hazard.
WARNING: Before using the sander with
metal, always remove the dust bag from the outlet as
sparks may ignite the dust or the bag.
WARNING: Always switch off and unplug the
power tool prior to any adjustment, servicing or main-
tenance or in case of mains drop-out.

MOUNTING THE SANDPAPER
Use only hook-and-loop sandpaper.

up the sanding disk (12). Press the sandpaper (11) to the
disc (12). Ensure the alignment of the disk and the sand-
ing sheet apertures to achieve proper dust extraction.

DISMOUNTINGTHE SANDING DISC
Withdraw the plug from the power supply socket. Dis-
mount the sandpaper (11) from the disc (12). Support-
ing the disc by hand remove the four screws (14) and
dismount the disc. Mounting the disc is performed in
reverse order.
SANDING
Place the power tool flat on the machined piece. Efficien-
cy and quality of work depends on the applied pressure,
sandpaper grit and rotation speed. Rotation speed can
be adjusted smoothly, by rotating the dial of the elec-
tronic regulator (3).
Rough sanding
Thicker layer will be removed when using sandpaper
with coarse grit and by applying less pressure on the
machine.
Fine sanding
For this purpose fine sandpaper is used. When increas-
ing the pressure on the machine the grinding disc runs
slowly, preserving its eccentric movement, and high
quality of the surface is achieved.
SPEED ADJUSTMENT
The desired speed can be pre-selected, by rotating the
dial of the electronic regulator (3).
