Packing, transportation and storage information
ATTENTION: All operations concerning packing, lifting, moving,
transporting and unpacking must be carried out by qualified personnel only.
Packing
The wheel balancer is sent as a complete piece of equipment (quick change holder,
wheel balancer, protective hood, operating manual). The wheel balancer can be
packed in a few different ways:
-pallet + stretch foil + carton box
-pallet + stretch foil
-palet + carton box
Transport
The package can be lifted or displaced by fork-lift or pallet trucks. Once the cargo arrives

machine.This manual is an integral part of the wheel balancer and should always
accompany the machine even if it is going to be sold.
ATTENTION: It is strongly advised to read carefully and repeatedly chapter
3 in which very important information and warnings concerning safety are
contained.
1.2 Preliminary work with the wheel balancer
ATTENTION: Lifting, transportation, unpacking, assembly, installation,
putting in motion, preliminary adjustment and testing, maintenance repairs,
technical inspections, do not require the presence of service personnel but
must be carried out with extreme precaution.
The manufacturer does not bear any responsibility for personnel injuries or
vehicle and other object damages if any of the above mentioned operations
will be performed not according to the service manual or the balancing
machine was used in an improper way.
In the manual only the aspects of the servicing and security which can help operators and
servicing personnel in a better understanding of the construction and working of the
wheel balancer and to allow them to use it the best way possible were enumerated.
To understand the vocabulary used in the manual, operators must possess specific
experience in servicing, maintenance, repairs, workshop works and ability to correctly
decode all drawings and descriptions contained in the manual. Operators must also know
general and detailed safety requirements obligatory in the installation country. The word
"operator" used in this manual should be understood in the following manner: Operator: a
person licensed to service a wheel balancer.

2. Description of the wheel balancer
DWC-9-E wheel balancer are designed for balancing of car and motorcycle wheels
in a single measurement cycle. Original construction solutions assure safe, simple and
comfortable operating of the machine as well as reliability and fast wheel balancing.
The wheel balancer is equipped with:
•quick mounting holder
•hood
•LCD display
•sound speaker
•automatic calibration program
•"Hidden weight" program
•optimisation program
•imbalance recalculation
•ALU program for working with aluminum rims
•user memory bank
The wheel balancer has following attributes:
•modem measurement system with a computer system for data processing to ensure
fast and complete measurement with great accuracy,
•the possibility to choose a program for wheel handling (also for light aluminium
rims) with every type of balancing weights - hammered or adhesive,
•the possibility of regulating balancing accuracy, according to the wheel’s mass and
state,
•easy programming and measurement with an ergonomic keyboard design,
versatility of special holders enabling attachment of almost all wheel types,
•automatic calibration system that allows the machine to regulate the measurement
system on its own if operator assumes incorrect imbalance indications of the
•machine,

3. Safety
WARNING: This chapter should be read carefully because it contains
important information for operators and other persons concerning hazards of
using the wheel balancer in an inappropriate way.
Below are explanations concerning hazards and risks which can occur during balancing
machine operating and maintenance. General and detailed precautions are given for
avoiding potential hazards.
WARNING: The DWC-9-E wheel balancer was designed for the
balancing of car and motorcycle wheels in one measurement cycle. Any work
with the wheel balancer should be preceded by comprehensive reading
and understanding of this manual. Any other type of usage of this balancing
machine is not allowed. In particular, the wheel balancer is not intended
for balancing other elements.
ATTENTION: The manufacturer and the dealer do not bear any
responsibility for personnel injuries or vehicle and other objects' damages in
case of improper or unauthorized use of the wheel balancer!
Any operation of the wheel balancer is not allowed without prior closing
of tiie hood. Not satisfying the above mentioned recommendations can result
in serious human injuries and irreparable wheel balancer's damages and
wheel damages.
3.1 General precautions
It is required that the operator and the maintenance technician adapt safety rules obligatory
in the country of installation. Moreover, the operator and the maintenance staff should read
all the information regarding safety placed on the machine and all the information included
in this manual.
Risk of electric shock - hazard of electric shock can occur in those wheel balancer
areas, where electric cables are placed. Use of water sprayers, vapour sprayers (high
pressure washing units), dissolvers and painting equipment is not allowed in vicinity of the
wheel balancer and in particular they should not be in contact with the control unit.
Impact risk - during operation of the machine here is a risk of some parts of the balancing
machine hitting the operator. With the protective screen open, personnel must preserve all
precautions to avoid hitting against machine parts.
Risk of wheel easing - before balancing starts, one should check if the wheel is properly
and firmly fixed in the machine's holder.
