1. Foreword
Dear customer,
Please read this user manual carefully before first using your truck-mounted concrete pump, so as to ensure that
you use it safely and effectively.
We have written this user manual to familiarise you with the design, use, operation and operating conditions, and
to list the servicing and maintenance work required, together with information on safe working.
Before starting to use the truck-mounted concrete pump, be sure that all the safety conditions have been
satisfied.
This user manual forms part of the total documentation package for the truck-mounted concrete pump. It relates
exclusively to the superstructure that is fitted to the truck. For the truck itself see the separate user manual issued
by the truck manufacturer. There may be separate user manuals for certain components and options. These user
manuals should also be read and complied with.
All repair work should be performed only by authorised skilled staff.
If maintenance work is neglected or improperly performed, we may no longer be liable to perform our warranty
obligations under our conditions of supply.
Only original WAITZINGER spare parts ensure quality and interchangeability.

墌We reserve the right to make technical changes and improvements to
the equipment and its components from the illustrations and data set
out in this user manual.
墌This user manual is applicable only insofar as the truck-mounted
concrete pump corresponds to the version and equipment described.
墌In the following sections the truck-mounted concrete pump is also
referred to as the “machine” or “equipment”.
Only qualified and trained personnel over 18 years of age may work on and with the truck-mounted concrete
pump.
Our customer service department will be pleased to offer you further information and advice if despite consulting
this user manual you encounter any problem with your truck-mounted concrete pump.
We wish you all the best in trouble-free driving and use of your truck-mounted concrete pump.

墌Work on or with the machine may be performed only by suitably instructed reliable personnel and/or technical
staff.
墌Before starting work it should be determined which personnel shall perform the necessary operating and
maintenance work.
墌When operating the machine the legislation and regulations applicable at the place of use should be observed.
In the interests of safe working procedures, the user, supervision and equipment operator are responsible for
complying with regulations.
墌Before starting work, all necessary functional checks should be performed on the machine.
墌Items not required in the immediate working process (tools, lubricants, cleaning materials, etc.) must be stowed
only in their proper places, since otherwise they may obstruct safe operation.
墌During cleaning work, especially with solvents or petrol washes, safety gloves and safety glasses must be
worn. No naked lights or smoking when cleaning is being performed! Disposal of consumable materials to TA
waste code 524.02 should be to EC directive 91/689/EWG.
墌Consumables such as lubricants, cleaning materials during maintenance, repair and oil change should be
collected in suitable containers and disposed of in accordance with regulations (to EC directive 75/439/EWG
and statutory instruments under §§ 5a, 5b AbfG and AltölV).
2.6 Information on risks of injury
Improper use of the truck-mounted concrete pump may lead to the following injuries:
墌Injuries to the eyes due to splashes of concrete, concrete mixing water or other chemical substances.
墌Injuries to the eyes and other injuries due to hydraulic oil spurting out if the system is not depressurised.
墌Injuries due to centrifugal forces of bursting couplings, bursting pipework or plugs blown out of the concrete
conveying pipework.
墌Hazards of touching electrical cables.
墌Electric shock (which can be fatal) from machines with electrical drives, if electrical connections are not properly
made or the connecting cables are defective.
墌Danger of tipping over due to collapse of the outriggers.
墌Injuries due to burns if hot parts are touched.
墌Injuries due to falling pipes.
墌Injuries to personnel due to inadvertent operation of the machine controls and hence inadvertent operation of
the machine.

墌Head and shoulder injuries due to concrete discharging from the discharge hose or concrete conveying pipes.
墌Injuries due to parts falling from the concrete conveying pipes, if these are not properly aligned.
墌Injury to the hose operator from the discharge hose if this was secured in the catch and then suddenly swings
out on release.
墌The truck-mounted concrete pump can roll away if the brakes or outriggers are released.
墌Injuries due to opening the conveying pipes when they are under pressure due to a blockage.
墌Injuries due to reaching into the agitator hopper, or falling into it.
墌Injuries due to slipping from or on the oily and slippery walkways on the machine.
墌Injuries during pumping operations due to reaching into the water tank at the same time as the piston is in
motion.
墌Amputation of the hand if the arm is trapped in the S-valve when cleaning with the flap elbow open.
墌Injuries due to tripping over cables, hoses or reinforcing rods.
墌Injuries due to being caught in the mixing hopper or its parts (chute).
墌Injuries due to unsecured conveying pipes slipping down or falling down.
墌Risk of crushing at the complete outriggers.
墌Injuries due to unintended movement of the distributor boom following inadvertent operation of the controls.

2.7 Safety information for setting up
DANGER:
墌The distributor boom should not be moved before all the outriggers
have been fully extended and all support cylinders correctly set!
墌The truck-mounted concrete pump must not be driven with the
distributor boom deployed!
墌The safety regulations for the country in which the truck-mounted
concrete pump is being operated must be complied with!
2.7.1 Set-up location
When selecting the set-up location, the following aspects should be considered:
墌Check the route to the set-up location, if necessary have someone guide the driver to the location.
墌Keep a safe distance from obstacles such as site cranes, buildings and equipment.
墌Check there is sufficient room to extend the outriggers.
墌Check there is sufficient room to deploy the distributor boom.
墌Check there is sufficient ventilation to clear the vehicle exhaust gases.
2.7.2 Hazard area
The hazard area is the area around the truck-mounted concrete pump within which a person could encounter
movements of the distributor boom, the truck and the outriggers, and thus be at risk.
DANGER:
墌The is a risk of crushing when slewing and extending the outriggers
and when extending the support cylinders!
墌The operator must continually monitor the hazard area!
墌The outriggers must not be extended when personnel are in their area of movement. Interlock the outriggers
hydraulically or mechanically.

墌Press the Emergency Stop button immediately if anyone approaches the hazard area.
墌Extending the outriggers on only one side may be performed only of the manufacturer has approved this after
consideration of the stability of the arrangement, and the distributor boom is restricted so that it can only move
within the slewing arc specified for the situation.
2.7.3 Setting up
2.7.3.1 General
•Set up the truck-mounted concrete pump so that stability is assured.
•It must be at a sufficient distance from embankments, pits, excavations and other holes so that the pressure
of the outriggers on the ground does not cause it to break into the hole.

2.7.3.3 Underground
The ground must be flat, horizontal and without voids.
On sloping ground the outriggers can slip from timber
baulks.
2.7.3.4 Quality of ground
The ground must be of a quality sufficient to ensure the stability of the machine and the distributor boom. The
outriggers exert a surface pressure up to 260 N/cm2(26 kg/cm2). If the ground quality is insufficient to accept this
the bearing area should be enlarged with two crossed layers of support plates. See DIN 1054 for recommended
values.
