McHale W2020 Round Bale Wrapper

Introduction

This product is designed to wrap, with plastic stretch film, cylindrical section bales of

forage for the purpose of storage as fodder for livestock. The design has been

developed based on years of extensive research and development in the field of round

bale wrappers. Given proper care and attention, the machine will provide years of

reliable and dependable performance.

Please do not assume that you know how to operate and maintain your machine before

reading this manual carefully. In order to prevent misuse, damage and accidents, it is

very important that everybody who will operate the machine is a fully trained operator.

(See ‘Trained operator criteria’). They must read and fully understand all of the

contents of this manual, before operating the machine, paying particular attention to the

following:

Safety instructions

Functions

Controls (hydraulic & electrical)

It is highly recommended to get acquainted with any new machinery slowly. Take time

to learn and understand all of the features of the machine. Proficiency will increase as

more experience is obtained.

If you have any questions in relation to the instructions in the manual, please contact

your McHale dealer. It is highly recommended that training be sought from your local

McHale dealer.

The operator is solely responsible for the safe use and maintenance of the machinery,

in accordance with this manual. Keep this manual safe and make sure it remains with

the machine, at all times.

Product information

The machine is protected against many dangers to itself while being operated.

However, it is of the utmost importance for the safety of the operator and for others,

that the operator pays attention to all warnings and instructions given in this manual. In

particular all safety devices, decals, guards and controls must be in place and in fully

functioning condition. Never try to clear any malfunction when the tractor is switched

on or while the machine is running. Keep the ‘Danger Zone’ (an area around the

machine) free of all persons and animals at all times, while the machine is in operation

(See ‘Danger Zone’). This manual must be read and fully understood by anyone who

will operate the machine.

2.1 Designated use of the machine

The machine is exclusively designed for normal use in agricultural applications. The

machine has been designed to wrap cylindrical bales of forage with plastic stretch film

for the purpose of storing as fodder for feeding livestock. This designation includes the

movement of the machine, between fields by track or road, incidental to the wrapper’s

main use. The machine is designed to be used on a tractor three-point linkage or

mounted on an industrial type loader. The manufacturer will not be held responsible for

any loss or damage resulting from machine applications other than those specified

above. Any other use the machine may be put to is entirely at the owner/operator’s risk.

The designated use of the machine includes that:

The operating, maintenance and repair instructions given by the manufacturer

will be strictly fulfilled.

Exclusively persons who are familiar with it and instructed about the risks are

entitled to operate, maintain and/or repair the machine.

The relevant health and safety requirements that may be in force in the

country of use will be strictly followed.

No other equipment or accessories, other than released by McHale, are

installed in the machine. The use of any other equipment or accessory is

entirely at the owner/operator’s risk. In such cases, unauthorised

modifications/changes exclude any liability of the manufacturer.

WARNING: Loss of machine validity

By any alteration of safety equipment, the declaration of conformity and

the CE sign loses its validity for this machine.

(*) May not be available in all countries, check with your McHale dealer for availability

in your country.

Side-tip option

The side-tip option is used for knocking the bale onto its side and is very useful for

coarse ground with strong stubble (which may have a tendency to puncture the film),

as it allows the bale to land on its edge, which has a much higher degree of film

coverage. It is also very useful on hilly/sloping ground as it can prevent bales from

rolling, when they land on their side.
