BRIEF DESCRIPTION

This straight grinder has been designed to dock,
rough grind or plane metal and stone materials without the
need for a water supply.
BEFORE USING THIS TOOL
Before using the tool, make sure the mains voltage
is correct: it must be the same as that on the specification
label.
DISCS AND WHEELS
WARNING! For safety reasons always disconnect
the machine from the mains before changing the grinding
wheel.
The discs and wheels must be protected from bangs
and knocks.
Before starting up the machine, check that the grinding
wheel is securely clamped (see Fig. 2).
WARNING! Use protective goggles while working.
Do not use wheels of a larger diameter than that
shown on the specifications plate.
The centrifugal force tends to break the grinding wheel
as its speed increases. Said centrifugal force increases
proportionately to the square of the peripheral speed, thus,
for example, while the increase in the speed of a wheel in
going from 30 m/s to 35 m/s is 17%, the increase in the
centrifugal force is 36%.
Owing to the many different shapes of grinding
wheels with shank, the type of bonding and the degree of
hardness, no exact diameter capacity can be given. For

example, a cylindrical wheel of diameter 25 and height 19,
with ceramic bonding, allows a speed of 35,100 r.p.m. yet
the same diameter with height 50 only allows a maximum
speed of 15,900 r.p.m. The values shown in table 1 are
approximate for general operations.
For special applications it is always best to consult the
manufacturer. It is advisable to insert the shank as far as
possible inside the clamp in order to avoid any bending or
possible vibrating of the grinding wheel.
MOUNTING GRINDING DISCS AND WHEELS
WARNING! For safety reasons, the machine should
always be unplugged from the mains before changing the
disc or wheel.
To mount the grinding wheel, insert the clip into the
machine's clip-holder shaft, insert the grinding wheel with
the shaft in the clip and turn the nut with a 17-mm spanner,
while holding the nut in place with a 13-mm spanner.
The grinding wheel is dismounted by carrying out this
procedure in reverse order.
PRECAUTION. The clip securing nut must not be
tightened unless a grinding wheel has been inserted into
the clip.
Protect discs and wheels from knocks and blows.
WARNING! Check that the mains voltage is the same
as that in the machine's specifications.
Plug the machine in with the switch off.
Start the machine by turning the switch to position 1
(«ON»). To switch off, do the same in reverse.
Speed adjustments (Mod. SG6/1000CE)
The built-in module permits:
- Soft start.
- The maintenance of a practically constant rated speed
up to rated power.
The control electronics allow continuous pre-setting of
the revolutions to adapt the machine to the type of material
to be worked on. Adjustment is made using the speed
adjustment switch C, which has 6 positions to regulate the
speed.
