Pay particular attention to cleanliness at all times.
Safety requirements after completing maintenance and repair work
Ensure that all personnel is clear of danger zones before cranking.
Check that all access ports/apertures which have been opened to facilitate working are closed again.
Check that all safety equipment has been installed and that all tools and loose parts have been re-
moved (especially the barring gear).
Ensure that no unattached parts have been left in/on the product (e.g. including rags and cable straps).
Welding work
Do not perform welding on the product or its attachments. Cover the product when performing welding
work in the vicinity.
Before commencing welding work:
• Switch off the master power supply switch.
• Disconnect the battery.
• Disconnect electronic and genset grounds.
Do not perform maintenance or repair work on the product when welding is in progress in its vicinity.
Risk of explosion or fire due to oil vapors and highly flammable process materials.
Do not use the product as a grounding terminal.
Do not route the welding cable over or near the wiring harnesses of the product. The welding current
may otherwise induce an interference voltage in the wiring harnesses which could conceivably damage
the electrical system.
Remove components (e.g. exhaust pipe) from the product before performing necessary welding work .
Hydraulic installation and removal
Check function and satisfactory condition of the jigs and fixtures to be used. Use only the specified jigs
and fixtures for hydraulic removal/installation.
Observe the max. permissible force-on pressure specified for the installation/removal jig.
Do not attempt to bend or exert force on HP lines.
Before starting work, pay attention to the following:
• Vent the installation/removal jig, the pumps and the pipework at the relevant designated points.
• For hydraulic installation, screw on the jig with the piston retracted.
• For hydraulic removal, screw on the jig with the piston extended.
For hydraulic installation/removal jigs with central expansion pressure supply, screw the spindle into
the shaft end until correct sealing has been established.
During hydraulic installation and removal, ensure that nobody is standing in the immediate vicinity of
the component to be installed/removed.
Working with batteries
Observe the safety requirements of the battery manufacturer when working with batteries.
Gases released from the battery are explosive. Avoid sparks and naked flames.
Do not allow electrolyte (battery acid) to come into contact with skin or clothing.
Wear goggles and protective gloves.
Do not place tools on the battery.
Check polarity before connecting the cable to the battery. Battery polarity reversal may lead to injury by
the sudden discharge of acid or bursting of the battery unit.
