Safety measures

WARNING
During assembly work, especially within the engine compart‐
ment, due to the lack of space, bear in mind the following:
♦ All hoses (e.g. fuel, hydraulics, activated charcoal filter
system, cooling system and cooling gas, brake fluid, vac‐
uum) and electric cables must be restored to their original
positions.
♦ Provide easy access to all moving or hot parts.
If during a test drive it is necessary to use test and measuring
equipment, observe the following:
♦ Always install test and measuring equipment on the back seat
to be operated by someone from there.
If test and measuring equipment are operated from the passenger
seat, the person seated there may be injured should the airbag
activate in case of accident.
To prevent injuries to persons and/or damages to the injection
system and glow plugs, the following must be noted:
♦ The ignition must be switched off before connecting or dis‐
connecting test cables for injection and glow plugs.
♦ If the engine is to be turned over at starting speed, without
starting, e.g. to check compression, disconnect injector con‐
nector on cylinder head.
♦ Check if the vehicle has code radio; if so, request respective
anti-theft code before disconnecting the battery.
♦ Only disconnect and connect the battery when the ignition is
switched off; otherwise, the direct injection diesel command
system unit may be damaged.
