persons only. The marshaller giving the instructions must be within sight or sound of the operator.
Carry out maintenance and repair work only if the machine is positioned on stable and level ground
and has been secured against inadvertent movement and buckling.
If the machine is completely shut down for maintenance or repair work, it must be secured against
inadvertent restarting.
Clean the machine, especially connections and threaded unions, of any traces of oil, fuel or
preservatives before carrying out maintenance or repair. Never use aggressive detergents. Use lint-
free cleaning rags.
Before cleaning the machine with water or other cleaning agents cover or tape up all openings which -
for safety and functional reasons- must be protected against the ingress of water/ steam/ cleaning
agents. After cleaning, remove all covers and tapes applied for that purpose.
After cleaning, examine the machine for leaks, loose connections, chafe marks or damage. Any
defects found must be rectified without delay.

safety devices removed for set-up, maintenance or repair purposes must be refitted and checked
immediately upon completion of the maintenance and repair work.
2.6 Information about special risks electrical energy
Observe the relevant national regulations or standards. Electrical connections must always be kept
free from dirt and moisture. Use only original fuses with the specified rating! Switch off the machine
immediately, if trouble occurs in the electric power supply!
When working with the machine, maintain a safe distance from overhead electric lines. If work is to be
carried out close to overhead lines, the working equipment must be kept well away from them.
Caution, danger! Check out the prescribed safety distances.
If your machine comes into contact with a live wire:
• warn others against approaching and touching the machine
• have the live wire de-energized
Work on the electrical system or equipment may only be carried out by a skilled electrician himself or
by specially instructed personnel under the control and supervision of such electrician and in
accordance with the applicable engineering rules.
If provided for in the regulations, the power supply to parts of machines and plants, on which

mounted check the tension after 8 working hours.
Deflexion in the middle approx. 4 mm (0.16") - maximum deflexion force 19 N. Always use a set of V-
belts. Loosen the counter nut (1) WS 24 of the spindle (3) and tense the V-belts with the adjusting nut
(2) WS 24 until the correct tension is reached and fasten the counter nut (1).
Use always a set of V-belts!

electrician
Lowering
Machine does not fully lower! Undercarriage or threaded spindle
tight Check undercarriage and threaded spindel
Cutting
Dull diamond blade Sharpen or use softer

Damaged centering of the blade
shaft Replace blade shaft
Warped blade shaft Replace
Non circular abrasion of the
diamond blade! Loose or damaged blade shaft
bearings Tighten or replace
No free cut because of siedwards
wear-out of segments Replace diamond blade
Diamond blade jams in the cut Damaged diamond blade core Replace diamond blade
Insufficient water flow Check hoses for fracture free
laying
Wrong type of diamond blade Choose different diamond
blade
Feed too high Reduce feed
Abnormal wear-out of
segments
Cutting in loose underground Reduce cutting depth
Insufficient water flow Check hoses for fracture free
laying
Abnormal blade wear-out at
sides of core! Cutting in loose underground Reduce cutting depth
