Changing the Grinding Tool
Before changing the grinding tool, pull the
mains plug from the socket.
Wear protective gloves to carry and handle
the grinding head.
The maximum allowable speed of the grinding tool
being used must correspond at least with the maxi-
mum speed of the machine.
The grinding tool may not vibrate or run out of bal-
ance; replace otherwise.
Use only original Protool grinding tools.
Inserting the Grinding Head
Use suitable grinding head depending on the applica-
tion and application range (see application table).
Place the machine on a level and sturdy support (e. g.
workbench).
Insert the pin (13) through the hole in the socket span-
ner, size 10 mm (14) as a lever extension and loosen the
clamping bolt (15) (see figure A).
Insert the grinding head (16) into the spindle (17) (see
figure B). Pay attention to the position of the fitting
key (18), it must not change its position.
Insert the second pin (13) through one of the extraction
holes on the grinding head and into the respective hole
of the machine (see figure C).
Lock the grinding head in place with the pin (13) and
tighten the clamping bolt (15) well with the socket
spanner (14).
Before starting operation, check the proper
run of the grinding tool by turning manually.
Pay attention that all screws/bolts are tight-
ened well. Do not leave any tool wrenches
attached
Removing the Grinding Head
Caution! The grinding head can become very
hot during the working process. Before
replacing, allow the grinding head to cool
down.
Loosen the clamping bolt (15) with the socket
spanner (14).
Screw in the extractor (19) and loosen the grinding
head by turning the lever in clockwise direction (see
figure D).
As soon as the grinding head has become loose it can
be removed.
Replacing Grinding Wheels
Decreasing removal capacity over the coarse of time is
an indicator of wear and the necessity for replacement
of the grinding head.
Grinding heads equipped with replaceable grinding
wheels that have become dull can be reused again with
a replacement set.
Place the removed grinding head on a clean and level
supporting surface.
Loosen the two stud bolts (20) and remove them (see
figure E).
Take off the inner ring (21).
Pull the bearing pin (24) toward the inside and take out
the grinding wheels to the top (see figure F). Repeat the
procedure for the other grinding wheels.
When assembling new grinding wheels, pay attention
to the correct assembly sequence.
When replacing, always replace the complete set of
grinding wheels.
Before inserting the grinding head, check the
proper run of the grinding wheels by turning
manually.
Operational Tips
Place the switched-on machine onto the material sur-
face and move it parallel and with circular motion in
length or traverse direction.
The removal capacity is determined mainly by the
choice of grinding tool as well as the applied pressure.
An overly increase of the applied pressure does not
lead to a higher removal capacity, but only to increased
wear of the machine and the grinding tool.
During the working procedure, pay attention that the
vacuum hose is not bent or damaged.
A malfunction of the extraction system leads to
increased strain through dust and increases the wear of
the grinding tool.
Please note: Check whether the milling disks always
rotate freely on the arbors during work. If deposits
of dust prevent this these deposists must be
removed from the milling head (e.g. by knocking
out). Never work without closed dust extractor
hood.
