dimensions are appropriate for the machine.
Utilization of reduction bushes or extensions to
adapt wheels with arbour exceeding the recom-
mended is forbidden.
Dismounting:
Unwind the screw 4 for fixing the groove depth
entirely. Rotate the arm until the chasing set
exits completely from the wheel guard. Fix the
spindle by pressing button 15 on the gear case
of the machine.
WARNING: Never press the lock
button while the spindle is still rotating!
With button 15 depressed, rotate the spindle
until the button sinks distinctly. Unscrew lock
nut 14 by the two-pin spanner. Remove and
clean from debris lock nut 14, spacer washers
13 and flange 11.
ASSEMBLY AND ADJUSTING THE
GROOVE WIDTH
Place flange 11 onto the spindle and rotate until
stop. Place the first wheel 12 onto flange 11.
Do not place spacer washers between flange
11 and the first wheel 12. Take care that the
arrows, indicating rotation direction on the ma-
chine gear case and the wheel coincide. The
total width of spacer washers 13, between the
wheels, specifies the groove width. There must
be at least one spacer washer between the
wheels 12. Regardless of the groove width,
all spacer washers 13 must be mounted. By
request it is possible to operate the machine
with one wheel 12 only, with all 6 spacer wash-
ers placed behind it. Screw lock nut 14. Fix the
spindle by pressing the spindle lock button.
Tighten lock nut 14 with two-pin spanner. Ro-
tate the arm until the chasing set is hidden into
the wheel guard. Place the screw 4 for fixing
the groove depth back and tighten it.
TESTING THE NEW WHEELS
Operate the wall chaser with new wheels for
one minute at no load. Vibrating or otherwise
improperly rotating wheels must be replaced
immediately.
ADJUSTING THE CUTTING DEPTH
To avoid unevenness during chasing, adjust
the cutting depth 2-3 mm deeper than the nec-
essary. Release screw 4 for fixing the cutting
depth, set the desired depth by scale 10, and
then tighten screw 4.

WHEEL GUARD
This power tool is delivered with a wheel guard;
never operate the power tool without the wheel
guard.
The wheel guard can be removed by screw 7.
The wheel guard position towards the driving
machine can be shifted within narrow limits.

AUXILIARY HANDLE

The auxiliary handle 8 is fastened by built-in
screw to the wheel guard. Operating the ma-
chine without the auxiliary handle is not al-
lowed.
The auxiliary handle for these models is con-
nected to the body of the machine through vi-
bration dampers, protecting the operator and
reducing fatigue.
ELECTRONIC DEVICE
This power tool is equipped with an electronic
device to accomplish the following functions:
- Soft start and restriction of the starting
current. This ensures starting the machine
without jerks and prevents occurring voltage
fluctuations in the supply network;
- Maintaining constant speed in a wide
range of loading;
- Protection from brief overloads. Upon
major brief overloads a current overload pro-
tection actuates, which reduces the rotation
speed. To resume normal operation withdraw
the machine from the material.
- Thermal overload protection. Upon minor
long overloads, the thermal overload protection
actuates and switches the motor off prior to
reaching critical temperature values. The ma-
chine switches from operation mode to safety
mode specified with low motor speed. The
machine is disabled. In safety mode the motor
rotates at low rpm to accelerate cooling, but the
machine is DISABLED. To resume operation
after cooling down for approximately 3-5 min,
switch the trigger off and on again.
- Safety upon mains drop-out. In case of
mains drop-out or unplugging for more than
0,5 s the power tool ceases operation even if
the ON/OFF switch is locked in ON position. To
resume normal function of the power tool, first
switch off and then switch on the lever of ON/
OFF switch.
GROOVE CHASING (Fig.2)
Always guide the tool with both hands. Place
the machine on the front roller guides (1), pull
the handle up, so both diamond wheels can
