1 Foreword
This operator's manual contains information and procedures for the safe opera-
tion and maintenance of your Wacker Neuson machine. In the interest of your
own safety and to prevent accidents, you should carefully read through the safety
information, familiarize yourself with it and observe it at all times.
This operator's manual is not a manual for extensive maintenance and repair
work. Such work should be carried out by Wacker Neuson service or authorized
specialists.
The safety of the operator was one of the most important aspects taken into con-
sideration when this machine was designed. Nevertheless, improper use or in-
correct maintenance can pose a risk. Please operate and maintain your Wacker
Neuson machine in accordance with the instructions in this operator's manual.
Your reward will be troublefree operation and a high degree of availability.
Defective machine parts must be replaced immediately!
Please contact your Wacker Neuson representative if you have any questions
concerning operation or maintenance.

objects can easily get caught or be drawn in by moving machine parts.
Personal protective gear
Wear personal protective gear to avoid injuries or health hazards:
Non-skid, hard-toed shoes.
Work gloves made of durable material.
Overalls made of durable material.
Hardhat.
Ear protection.
Ear protection
This machine generates noise that exceeds the country-specific permissible
noise levels (individual rating level). It may therefore be necessary to wear ear
protection.
WACKER recommends that you always wear ear protection.
2.4 Transport
Switching off the machine
Before you transport the machine, switch it off and pull the mains plug out of the
plug receptacle.
Transporting the machine
Secure the machine on the transport device against tilting, falling or slipping.
Restarting
Machines, machine parts, accessories or tools that were detached for transport
purposes must be re-mounted and fastened before restarting.
Only operate in accordance with the operating instructions.
External vibrators
SV00079GB.fm 10

The load-carrying capacity of the ground.
The measures needed to cordon off the construction site from public traffic.
The measures needed to secure walls and ceilings.
Options available in the event of an accident.
Starting the machine
Observe the safety information and warnings symbols located on the machine.
Never attempt to start a machine that requires maintenance or repairs.
Start the machine as directed in the operator's manual.
Vertical stability
Always make sure that you maintain a safe distance when working with the
machine. This applies particularly when working on scaffoldings, ladders, etc.

Electric power supply with residual current protective device (42 V AC)
Note: The rated voltage is indicated on the nameplate of your machine.
The machine may only be connected to an electric power supply with all machine
parts in proper working condition:
Mains plug.
Power cable over the entire length.
There must be at least one of the following safety devices if connected to a
stationary or mobile generator:
Transformer with safe separation in accordance with EN 60742.
Motor generator with equally separated windings.
Note: Observe the respective national safety regulations!
Power supply with residual current protective device (> 50 V AC)
Note: The rated voltage is indicated on the nameplate of your machine.
The machine can be connected to a 15 A/16 A shock-proof plug receptacle
(continental type) with a corresponding overload protection.
One of the following fault current protective switches is required:
Standard fault current protective switch (AC sensitive, type A).
AC/DC sensitive fault current protective switch (type B).
The machine may only be connected to an electric power supply with all machine
parts in proper working condition:
Mains plug.
Power cable over the entire length.
The machine may only be connected to an electric power supply with the
protective earth (PE) connector intact.
There must be at least one of the following safety devices if connected to a
stationary or mobile generator:
Fault current protective switch
Isolation (earth leakage) monitor
IT-net
Note: Observe the respective national safety regulations!
Extension cable
The machine may only be operated with undamaged extension cables!
Only use extension cables with grounded conductor and correct connection of
the grounded conductor to the plug and coupling (not for 42 V machines).
Only use extension cables which are suitable for use at construction sites:
Average rubber hose line H05RR-F or better – WACKER recommends
H07RN-F.
Immediately replace damaged extension cables (e.g. tears in the sheathing) or
loose plugs and couplings.
External vibrators
SV00079GB.fm 12
Protecting the power cable
Do not use the power cable to pull or lift the machine.
Do not unplug the mains cable by pulling on the cable.
Protect the mains cable from heat, oil and sharp edges.
If the power cable is damaged or the plug is loose, have it replaced immediately
by your WACKER representative.
2.7 Safety during the operation of external vibrators
Attaching the safety strap
If using the external vibrator in conjunction with a clamp, always attach the clamp
to the formwork using the safety belt supplied.
Attach the safety belt above the external vibrator securely to the formwork. The
safety belt should be taut without slack to ensure the clamp and the external
vibrator are caught by the safety belt in the event of a fall and stopped from falling
too far.
Motor protection against overload
To protect the motor against overload, WACKER recommends the use of a
motor-protective circuit-breaker.
Using stable formwork
Only use stable molds and formwork for attaching the external vibrator. Tighten
the fastening screws.
Molds and formworks that are not firm enough or loose connections may
overload the motor or result in being damaged themselves.
Check whether your formwork is suitable for receiving external vibrators:
Attachment possibility.
Sufficient stability for the used external vibrator type (dependent on the
performance).
Your WACKER representative will be happy to assist you.
Using the correct clamp
Attach the external vibrator using the clamp which is suitable for the external
vibrator and the formwork.
2.8 Maintenance
Maintenance work
Service and maintenance work must only be carried out to the extent described
in these operating instructions. All other procedures must be performed by your
WACKER representative.
For further information, please see the chapter Maintenance.

Selection of required cross section for extension of cables and power lines
This procedure takes into consideration:
1. The ohmic and inductive resistance of the line with an admissible loss of voltage of 5% and cos phi = 0,8
as per voltage-frequency-curves.
2. The admissible warming-up of the lines as per VDE standard (table of required minimum cross section).
ATTENTION! The larger one of both cross sections has to be chosen.
Example:
Nominal voltage 3 ~ 400 V, 200 Hz
