Gremo1050F4 Instruction manual 1 Introduction
1.4 Intended area of use
1.4 Intended area of use
The machine must only be used for what it has been
designed and adapted for, i.e. forwarding forest raw
materials, the weight of which does not exceed the
machine's maximum load capacity, from felling site in the
forest to the roadside stacking area. All other use is
prohibited.
It is not permitted to rebuild or modify the machine without
Gremo's approval.
It is not permitted to operate the machine on public roads if
it has not been adapted to comply with national road safety
rules.
1.4.1 Improper use
Do not under any circumstances use the machine for
anything it is not designed for, e.g.
The crane
• should never be used to lift loads greater than it was
designed to lift.
• should never be used to tow or push objects.
• should never be used to lift people.
The machine
• should never be used for anything other than it has
been designed for i.e. loading and unloading timber.
• should never be used if any safety feature is out of
order, e.g. if any safety sensor is disconnected.
• should never be used if a window is broken or with the
door open.
• should never be loaded with weights greater than it was
designed to handle.
• should never be parked on a slope, but must always be
parked on level ground to prevent the machine rolling
away or capsizing.
1.4.2 Prohibited operation
It is prohibited to operate the machine if:
• Protection and warning equipment is out of order or
disconnected.
• If brakes or steering system are faulty.
5

1 Introduction
1.5 Operator requirements Gremo1050F4 Instruction manual
• If there are any unauthorised people or vehicles within
the machine's operating area.
1.5 Operator requirements
• The machine can only be operated by operators with
permission from work supervisors and the necessary
knowledge.
• National laws and regulations relating to driving
licences, operator certificates, etc. must be complied
with at all times.
• Operators must be aware of and follow all local safety
rules.
• Operators must follow the manufacturer's instructions.
• Operators must read and understand the machine's
warning and information signs, as well as understand
and be able to use the machine's protection and
warning equipment.
1.6 Safety regulations
Each country has its own national and local safety
regulations, and it is the responsibility of both the owner
and the operator to know and follow these regulations. If
the recommendations in this Instruction Manual differ from
the national and local safety regulations, then the national
and local safety regulations take precedence over the
recommendations in this Instruction Manual.
During the design and testing of the machine, a great deal
of effort has been made to make the machine safe and
efficient. These efforts may be completely wasted if the
safety and maintenance regulations are not followed.
Accidents are usually caused by humans, not by the
machine. A well-maintained machine and a safety-aware
owner/operator is a profitable and safe combination.
A Gremo machine meets the requirements of the
Machinery Directive and the harmonised standards, plus
national requirements and provisions.

1.8 Construction of the machine
NOTICE
This Instruction Manual is designed to be valid in several
market areas and for most factory-installed equipment.
Please ignore the paragraphs which are not valid for
your machine. We reserve the right to change and
improve the design whenever we find it necessary,
without undertaking to implement these changes on
products which have already been delivered. We also
reserve the right to change data and instructions for
maintenance, service, environment and safety without
further notice.
1.9 Definitions
In this Instruction Manual, the concepts of ‘front’, ‘rear’,
‘right’ and ‘left’ on the machine are defined according to
the principal direction of travel on roads, i.e. the direction
the machine travels when it is steered using the steering
wheel.
Example: the serial number of the machine is punched on
the frame in the front end of the machine, to the right of the
engine compartment.
1.10 Environment
The interplay between human beings, machines and the
environment can be influenced, and is becoming
increasingly important. We have paid attention to this
during the design of the machine and the writing of this
manual, which has a section relating to this subject. By
following these instructions when you drive and maintain
your machine, you will show consideration for humans,
animals and nature in your environment.
