For a hydraulic installation/removal device with central expansion pressure supply, screw spindle into
shaft end until correct sealing is established.
During hydraulic installation/removal of components, ensure that no persons are in the direct vicinity of
the component being pressed on.
Working with batteries
Observe the safety instructions of the battery manufacturer when working with batteries.
Gases released from the battery are explosive. Avoid sparks and naked flames.
Do not allow electrolyte to come into contact with skin or clothing.
Wear protective clothing, goggles and protective gloves.
Do not place tools on the battery.
Before connecting the cable to the battery, check the battery polarity. Battery pole reversal may lead to
injury through the sudden discharge of acid or bursting of the battery body.
Working on electrical and electronic assemblies
Always obtain the permission of the person in charge before commencing maintenance and repair work
or switching off any part of the electronic system required to do so.
De-energize the appropriate areas prior to working on assemblies.
Do not damage cabling during removal work. When reconnecting, ensure that cabling cannot be dam-
aged during operation by:
• Contact with sharp edges
• Chafing on components
• Contact with hot surfaces.
Do not secure cables on lines carrying fluids.
Do not use cable straps to secure cables.
Always use connector pliers to tighten union nuts on connectors.
Subject the device as well as the product to a functional testing on completion of all repair work. In
particular, check the function of the engine emergency stop feature.
Store spare parts properly prior to replacement, i.e. protect them against moisture in particular. Pack-
age faulty electronic components or assemblies properly before dispatching for repair:
• Moisture-proof
• Shock-proof
• Wrapped in antistatic foil if necessary.
Working with laser devices
Laser work must only be performed by authorized and trained personnel. When working with laser
equipment, always observe the safety instructions in the manufacturer's Operating Instructions.
When working with laser equipment, always wear special laser-protection goggles (hazard due to heavi-
ly focused radiation).
Laser devices must be equipped with protective devices in accordance with their class and usage to
ensure safe operation.
Measuring deviations on components
At a reference temperature of 20 °C, workpieces, components and measuring instrument are within the
specified tolerances.
