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

at its destination, it is recommended to check if its contents have not been damaged during

transportation. It is also recommended to check the conformity of the delivery with its bill

of landing. In case of non-conformity or transportation damages it is necessary to inform

important information concerning personal security of the operators and

maintenance personnel as well as wheel balancer’s operation.

1.1 The manual

For proper usage of this manual, the following should be applied:

-The manual must be kept in the proximity of the machine in a place of easy access.

-The manual must be kept in a dry place.

-The manual must be used properly with care not to damage it.

It is forbidden for operators who have not studied this manual to work with a balancing

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.
