Haldex Turbo-Saver DQ6031 Guia De Inicio Rapido página 2

When working on air system components the following precautions
should be observed.
1. Stop engine when working under a vehicle. Always block the vehicle
wheels to prevent a fore or aft roll. Bleeding off system air pressure
may cause the vehicle to roll. Keep hands away from brake chamber
push rods and brake adjusters; they may apply as system pressure
drops.
2. Never connect or disconnect a hose or line containing air pressure.
It may whip as air escapes. Never remove a component or a pipe
plug unless you are certain all system air pressure has been
exhausted.
3. Never exceed recommended working air pressure and always wear
safety glasses when working with air pressure. Never look directly
into component ports or direct a pressurized air flow at anyone.
4. Never attempt to disassemble a component until you have read and
understood all recommended procedures. Some components contain
powerful springs and injury can result if not properly disassembled.
Use only proper tools and observe all precautions pertaining to the
use of those tools.
