1.5 Safety requirements for maintenance and repair work
Safety requirements before commencing maintenance and repair work
Have maintenance or repair work carried out by qualified and authorized personnel only.
Allow the product to cool down to less than 50°C (risk of explosion for oil vapors, fluids and lubricants,
risk of burning).
Relieve pressure in fluid and lubricant systems and compressed-air lines which are to be opened. Use
suitable collection vessels with a sufficient filling volume.
Ensure that the operating room is adequately ventilated when changing the oil or working on the fuel
system.
Do not perform maintenance or repair work when the product is running unless:
• expressly instructed to do so.
• the product is running in the low load range and only for as long as necessary to complete the task.
Lock-out the product to preclude undesired starting, e.g. start interlock.
Tag-out the product with a “Do Not Start” sign in the operation room or on the control facility.
Disconnect the battery. Lock the contactor.
Close the main valve on the compressed-air system and vent the compressed-air line when pneumatic
starters are fitted.
Disconnect the control facility from the product.
For starters with pinions made of copper-beryllium alloy:
• Wear a respirator mask (filter class P3). Do not blow out the interior of the flywheel housing or the
starter with compressed air. Clean the interior of the flywheel housing with a class H dust extractor.
• Observe the safety data sheet.
Safety requirements during maintenance and repair work
Take special care when removing vent plugs or plug screws from the product. Hold a cloth over the
screw or plug to prevent discharge of highly pressurized liquids.
Take care when draining hot fluids and lubricants (risk of burning).
Use suitable and calibrated tools only. Observe the specified tightening torques during assembly or dis-
assembly.
Carry out work only on assembles and/or installations which are properly secured.
Never climb up on the lines.
Keep fuel injection lines and connections clean.
Always seal connections with caps or covers if a line is removed or opened.
Fit new seals when re-installing lines.
Avoid damaging lines, particularly the fuel lines.
Ensure that all retainers and dampers are installed correctly.
Ensure that all fuel injection and pressurized oil lines are installed with enough clearance to prevent
contact with other components. Never route fuel or oil lines in the vicinity of hot components.
Do not touch elastomeric seals (e.g. Viton sealing rings) with your bare hands if they have a carbonized
or resinous appearance.
Observe the cooling time for components which have been heated for installation or removal (risk of
burning!).
Always use suitable ladders and work platforms when working above head-height. Ensure that compo-
nents or assemblies are placed on stable surfaces.
