Starting & Stopping
Make sure that the following steps have been taken before starting the machine:
• Check the packing list to ensure that all necessary items have been
received.
• The machine and workstation is in a thermally stable environment (see
Specifications).
• The machine has been leveled such that the bridge does not drift when all
axis lock switches are unlocked and the probe holder is not being held.
• Check to ensure the machine was installed according to the specifications
in the Installation Manual.
• Verify that all shipping brackets have been removed.
• Check the input air supply pressure. It should be between 4.8 to 8.3 BAR
(70 and 120 psi) and should provide for a minimum consumption of
21L/min (.74 CFM). The pressure should be relatively constant and not
subject to drastic changes. The air supply should also be relatively free of
contaminants. NOTE: The maximum air pressure is 8.3 Bar (120 psi)
• The air supply is connected and the regulator is factory set to the correct
pressure. The pressure gage displays 3.7 BAR (55±1 psi). The pressure has
been preset at the factory. If the pressure is not correct, unlock the knob at
the bottom of the regulator, adjust the pressure, and relock the knob.
• All cables from the machine to the MH3D controller (ie. encoder, ground,
ZMouse and, if included, TTP, etc.) are connected (reference the
schemtatics).
• Ensure that the power supply and, if included, the printer is properly
connected. For additional information about the printer, refer to the
manufacturer’s technical publications for operating procedures.
• Verify that all machine guards and covers are in place.
• Wipe all exposed ways and the table work surface with alcohol and a
clean, soft cloth to remove dust or residue. (Reference the Cleaning
Bearing Surfaces in Preventive Maintenance Section)
