Security
WARNING!
- Ensure that the operator has read and understood this manual before the unit is in use.
- For security reasons, any modification of the drilling/tapping unit and it’s accessories, which may affect
product safety, must be approved by the manufacturers technical manager.
- The unit is intended for drilling, countersinking, reaming and tapping and should not be used for
any other application, unless approved by the manufacturers technical manager.
- Always follow local security regulations regarding installation, operation and maintenance.
- The unit must be securely fixed and the installation instructions must be strictly observed.
- The drilling/tapping unit must be protected against splash of emulsions, etc. This is to ensure the
units function as the lid for the micro-switches is not sealed against dust or liquid.
- When installing the unit on a stand or in a complete machine tool, necessary protective devices must
be fitted to prevent injury caused by crushing (squeezing) or any other type of personal injury that
might be caused by the unit or its rotating tool.
- In order to avoid personal injury, the unit's quill must not be run with compressed air in any direction
without first mounting safety plates over the limit switches and linear transducer. When changing
settings with these plates removed, measures must be taken prevent unintentional movement of the
quill, e.g. disconnecting control current or depressurizing the unit's feed cylinder.
- All protective devices that are designed to prevent personal injury must be mounted in their intended
position during the operation.
- When servicing or repairing the unit, the electrical system must be switched off and the pneumatic
system depressurized.
- Prior to disassembling the unit to change seals etc., the hydrocheck must be fully depressurized.
This is most easily accomplished using the bleed screw, See Fig. 15. Pos. 3, on page 14.
- When disassembling the end cover from the hydrocheck, be careful of the spring loaded piston inside
the hydrocheck.
- Beware of hands, gloves, hair and loose fit clothing – Watch out for rotating parts.
- Never operate the unit without any eventual safety arrangements – Beware of squeeze risk.
- Make sure that all hoses and electrical wires are safely fastened – Beware of squeeze risk.
