General
• Use only tools in perfect condition.
• Do not work on engines or components which are held only by lifting equipment or crane. Always support them
on suitable trestles or stands before beginning any maintenance or repair work.
• Before barring the engine, ensure nobody is within the danger area. After working on the engine, check that all
guards have been re-installed and that all tools and loose components have been removed from the engine.
• Fluids emerging under high pressure can penetrate clothing and skin and cause serious injury. Before starting
work, relieve pressure in systems and H.P. lines which are to be opened.
• Never bend a fuel line and do not install bent lines. Keep fuel injection lines and connections clean. Always seal
connections with caps and covers if a line is to be removed or opened.
• During maintenance or repair work, do not hit fuel lines with wrenches or other tools. To tighten connections
when installing lines, use the correct tightening torque and ensure that all retainers and dampers are installed
correctly.
• Ensure that all fuel injection lines and compressed-oil lines have sufficient play to avoid contact with other
components. Do not position fuel or oil lines near hot components.
• The H.P. lines for hydraulic installation and removal are tested at 3,800 bar.
• Do not attempt to bend or apply force to lines while under pressure.
• In order to avoid burns, pay special attention to hot spots on components just removed and when working with
hot liquids in pipelines, pipes and chambers.
• Do not open the breather cap until the engine has cooled. Turn the cap to the stop and allow the pressure to
escape; then remove the cap!
• Take special care when removing plugs or vent plugs from engine. In order to avoid being sprayed with highly-
pressurised liquids, hold a cloth over the plugs. There is increased danger if the engine has only recently been
shut down as the liquids can still be hot.
• Take special care when draining hot liquids - risk of injury. Drain the liquids into a suitable container and wipe up
any spillage.
• When changing engine oil or working on the fuel system, ensure that the engine room is adequately ventilated.
• When working high up on the engine, always use suitable ladders and work platforms. Make sure components
are placed on stable surfaces.
• To avoid back injuries when lifting components weighting 25 kg (50 lb) or more, use lifting gear or request aid
from other workers. Ensure that all chains, hooks, slings, etc. are in good condition, are sufficiently strong and
that hooks are correctly positioned. Lifting eyes are not to be unevenly loaded.
• When operating electrical equipment, remember that certain components of this equipment are live.
• Non-compliance with warning notices could result in serious bodily harm or damage to property.
• Work must be carried out by qualified personnel only. Prior to working on electrical equipment, switch off live
units.
• Gases released from the battery are explosive. Avoid sparks and naked flames. Do not allow battery acid to
come into contact with skin or clothing. Wear protective goggles. Do not place tools on the battery. Check
polarity before connecting the cables to the battery. Battery pole reversal may lead to injury through the sudden
discharge of acid or bursting of the battery casing.
