Safety and Environment Guidelines
Safety and Environment Guidelines
Note: The safety advice listed below is applicable to general service and diagnostic work on pneumatic systems. Also observe
any recommendations from the axle or vehicle manufacturer concerning towing, jacking-up and securing the vehicle.
Before and during working on or around compressed air systems and devices, the following precautions should be observed:
1
Always wear safety glasses when working with air pressure.
2
Never exceed the vehicle manufacturer’s recommended air pressures.
3
Never look into air jets or direct them at anyone.
4
Never connect or disconnect a hose or line containing pressure; it may whip as air escapes.
5
When removing or servicing a product, ensure all pressure related to the specific system it is contained in has been depleted
to 0 bar. Be aware that if the vehicle is equipped with an air dryer system, it can also contain air pressure along with its purge
reservoir, if fitted, even after pressure has been drained from the other reservoirs.
6
If it is necessary to drain the air pressure from reservoirs, etc., keep away from brake actuator push rods and levers since
they may move as system pressure drops. On vehicles fitted with air suspension, it is advised when undertaking such work,
to support the chassis from sudden lowering and therefore prevent any possibility of being trapped between the chassis and
axle or ground.
7
Park the vehicle on a level surface, apply the parking brakes, and always chock the wheels as depleting vehicle air system
pressure may cause the vehicle to roll.
8
When working under or around the vehicle, and particularly when working in the engine compartment, the engine should
be shut off and the ignition key removed. Where circumstances require that the engine be running, EXTREME CAUTION
should be taken to prevent personal injury resulting from contact with moving, rotating, leaking, heated or electrically charged
components. Additionally, it is advisable to place a clear sign on or near the steering wheel advising that there is work in
progress on the vehicle.
9
When working on vehicles equipped with air suspension, to guard against injury due to unexpected downward movement
of the chassis caused by sudden pressure loss in the suspension system, ensure that the vehicle chassis is mechanically
supported with a ‘prop’ between the chassis and the axle or between the chassis and the ground.
10 Examine all pipework for signs of kinks, dents, abrasion, drying out or overheating. Be aware that kinks in pipework may
result in air pressure being trapped in the pipework and associated equipment. Replacement hardware, tubing, hose, fittings,
etc. must be of equivalent size, type and strength as original equipment and be designed specifically for such applications
and systems. Check the attachment of all pipework; it should be installed so that it cannot abrade or be subjected to
excessive heat.
11 Components with stripped threads or damaged/corroded parts must be replaced completely. Do not attempt repairs
requiring machining or welding unless specifically stated and approved by the vehicle or component manufacturer.
12 Never attempt to install, remove, disassemble or assemble a device until you have read and thoroughly understood the
recommended procedures. Some units contain powerful springs and injury can result if not properly dismantled and
reassembled. Use only the correct tools and observe all precautions pertaining to use of those tools.
13 Before removing any device note its position and the connections of all pipework so that the replacement/serviced device
can be properly installed. Ensure that adequate support or assistance is provided for the removal/installation of heavy
items.
14 Only use genuine replacement parts, components and kits as supplied by Knorr-Bremse or the vehicle manufacturer. Only
use the recommended tools as specified in related service instructions.
15 The serviced or replaced product must be checked for correct function and effectiveness.
16 If products have been dismantled, serviced or replaced, whose performance could affect braking performance or system
behaviour, this should be checked on a roller dynamometer. Bear in mind that a lower performance may be experienced
during the bedding-in phase if new brake pads/linings and/or brake discs/drums have been fitted.
17 Prior to returning the vehicle to service, make certain that all components and the complete brake systems are leak free and
restored to their proper operating condition.
Safety and Environment Guidelines
Welding
To avoid damage to electronic components when carrying out electrical welding, the following precautions should be observed:
1
In all cases, before starting any electrical welding, remove all connections from any electronic control units or modules, noting their
position and the order in which they are removed.
2
When re-inserting the electrical connectors (in reverse order) it is essential that they are fitted to their correct assigned position - if
necessary this must be checked by PC Diagnostics.
Disposal of Waste Equipment by Business Users in the European Union
This symbol on the product, packaging or in user instructions, indicates that this product must not
be disposed of with other general waste. Instead, it is your responsibility to dispose of the waste
electrical and electronic parts of this product by handing them over to a company or organisation
authorised for the recycling of waste electrical and electrical equipment. For more information about arrangements for waste equipment disposal please contact your Knorr-Bremse distributor or local Knorr-Bremse
representative.

Description and Function
3.2 Description of Operation
Clutch Engaging Phase
Clutch Disengaging Phase
(Driver releases the clutch pedal)
(Driver pushes the clutch pedal)
As the driver allows the clutch pedal to lift, hydraulic
pressure decreases and the control piston (6) moves
under the influence of compression spring (7) and
of pressurized air. However, since the valve head (12) is
not able to move, due to being in contact with the valve
seat (11), a gap is created between control piston (6) and
valve head (12) and air is released to the exhaust port.
As both hydraulic and pneumatic pressure decrease, the
push rod assembly (22) moves backwards and hence the
clutch starts to engage. If the driver holds the clutch pedal
at any mid position, hydraulic pressure stops decreasing.
Air pressure will however continue to decrease resulting
in a reduction in force on the control piston. The latter will
therefore eventually move forward until it reaches the valve
head (12) and the exhaust of air is stopped. At this point,
the clutch is therefore only partly engaged.
As the driver pushes the clutch pedal, hydraulic pressure
increases on both the push rod assembly (22) and the
control piston (6). At a certain pressure, the control piston (6)
overcomes the compression spring (7) and moves forward,
therefore exhaust gap between control piston (6) and valve
head (12) is closed. As the valve head (12) continues to
move it is lifted from valve seat (11), pressurized air can
therefore enter the pneumatic space and act on piston
(23); thus assisting the forward load on the push rod and
helping the driver to disengage the clutch (servo effect).
When the driver stops pushing the clutch pedal further,
hydraulic pressure no longer increases. However, the gap
between valve head (12) and valve seat (11) is still open
and air pressure continues to rise, eventually moving the
control piston (6) backwards until the gap between valve
head (12) and valve seat (11) is closed. No further increase
of air pressure therefore takes place, an equilibrium state
is reached and the push rod assembly (22) stops moving.
Depending on the height of the clutch pedal, the clutch is
therefore partly disengaged. Further pushing of the clutch
pedal will repeat the above process. Full depression of the
clutch pedal will of course fully disengage the clutch
If the driver subsequently allows the clutch pedal to lift further,
the above process will be repeated until hydraulic pressure
becomes zero. When this happens, the control piston (6)
moves fully backwards and the gap between control piston
(6) and valve head (12) is continuously open. The clutch is then
fully engaged.
