1.5 Safety precautions when working on the engine Safety regulations prior to 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).
Page 11
Never bend lines and avoid damaging lines, particularly the fuel lines. Ensure that all retainers and dampers are installed correctly. Ensure that O-rings are not installed in a slanted/twisted condition. Ensure that all fuel injection and pressurized oil lines are installed with enough clearance to prevent contact with other components.
Page 12
During hydraulic installation/removal of components, ensure that no persons are in the direct vicinity of the component being pressed. 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 battery acids to come into contact with skin or clothing.
Compressed air Observe special safety precautions when working with compressed air: • Unauthorized use of compressed air, e.g. forcing flammable liquids (hazard class AI, AII and B) out of con- tainers, risks causing an explosion. • Wear goggles when blowing dirt off workpieces or blowing away swarf. •...
