Cleaning Surfaces; Electrical Connection - HOLZMANN MASCHINEN GBM25 Manual De Instrucciones

Anchor the gearbox drill underground using the continuous drilling in the base. The specific depth
of anchoring required depends on the hardship/consistency of the subsoil – the harder the less
depth is required. Attach the machine with suitable screws. To level, use discs to avoid harmful
stresses when tightening the screws (nuts).

14.1.3 Cleaning Surfaces

Remove the corrosion repellent applied to the bare parts of the machine for transport and storage
and oil that machine parts with an acid-free lubricant oil.

14.2 Electrical Connection

Working on an ungrounded machine can result in serious injury or even death.
Ground the machine! Operation is only allowed with safety switch against stray
current (RCD max. stray current of 30mA). Use only suitable extension cables with
appropriate cross section (see table below)!
Check the direction of the engine immediately after installation of the electrical
connection. In the „R" (right-hand) position of the switch, the drill spindle must
rotate clockwise!

Note that work on electrical components or equipment may only be carried out by an electrical
professional or carried out under the guidance and supervision of an electrical specialist.
Furthermore please take note of the following points:
• The connector, if any, must not be manipulated.
• The grounding wire is yellow-green.
• The main supply must be secured with 16 amps.
Check that the power voltage matches the requirements of the machine.
Check the correct direction of running (3 phases) after the electrical connection.
• If the machine is going in the wrong direction, change two phases (400 V)
• Make sure that any extension cable is in good condition and suitable for power transfer. An
undersized cable reduces power transmission and heats up a lot.
•
A damaged cable must be replaced immediately
