Dust Extraction; Overload Protection - Wurth Master MSF 30 Instrucciones De Servicio

Fitting single diamond cutting disc (for single
cut, Fig. IV)
· Fit collar 15 in the correct position on the drive
shaft (shoulder to the outside) and turn until it is
locked.
· Fit diamond cutting disc to the collar 15. During
this process it is imperative you pay attention to
the direction of rotation information on the
diamond cutting disc and the product!
· Fit clamping nut 11 and the spacers to the drive
shaft on the product. During this process tighten
the clamping nut 11 by turning it clockwise.
· Press in locking knob 12
· Slowly rotate diamond cutting disc until the locking
knob 12 engages.
· Tighten the clamping nut 11 using the flange
spanner supplied.
Never press in locking knob 12 with the
product running; also not when the
product is running down!
Placing device in operation (Fig. I and II)
After the diamond cutting discs have been fitted, the
guard 9 and the guide shoe 10 must be re-fastened.
For this purpose push the two parts together and fasten
using hex socket head screw 3. Re-tighten hex socket
head screw 7.
Adjusting cutting depth
Slightly undo star-shaped knob 4 and adjust to suit the
required cutting depth (as per scale 1).
Re-tighten star-shaped knob 4.

Dust extraction

The product can be connected directly to the socket
on a WÜRTH industrial vacuum cleaner with automatic
operation. The vacuum cleaner is started automatically
when the product is switched on.
For extraction, connect suction hose to adaptor and
insert in the opening on the extraction feature 5. Use
special adaptor (702 400 042, accessory) for this
purpose.
Never work with the product without
dust extraction, as otherwise the motor
may become clogged with dust very
quickly and damaged.

Switching on and off product
To switch on the product, push the slider switch 13
forward until it engages ('I' symbol). Readiness for use
is indicated by the brief illumination of the light emitting
diode 6.
To switch off the product, press down the rear end of
the slider switch 13. The slider switch 13 automatically
jumps to its initial position ('0' symbol).
Notes on use
Adjusting auxiliary handle
Undo hex socket head screw 14, adjust auxiliary
handle 2 and engage. Re-tighten hex socket head
screw 14.
Cutting guide
At the rear end of the guide shoe 10 there is a red
triangular marking 8. The marking is in line with the
rear diamond cutting disc and is used as a cutting
guide when cutting channels.
Positioning product for cutting
Place the product (with the motor switched on) with the
guide shoe 10 on the surface in which the channel is to
be cut and slowly guide downward until the required
cutting depth is reached. Then pull the product in the
cutting direction, e.g. from top to bottom; or – for
horizontal cuts – sideways.
The waste left between the two cuts can be removed
with the tool provided.
Channels at larger depths in a hard material
(e.g. concrete) cannot be cut in one pass.

Overload protection

Safety clutch
An automatic safety clutch is fitted in the product's
gearbox.
This feature protects the operator from the high torque
that, e.g., can occur if the diamond cutting discs are
tilted when working. The safety clutch protects and at
the same time removes the load from the motor and the
product's gearbox.
If the safety clutch is tripped, immediately switch
off the motor (do not allow the clutch to continue
slipping!)
