1 Introduction
1.1 Introduction
For you to get the most out of your Gremo machine as an
owner or an operator, it is very important that you maintain
and handle the machine correctly.
It is also very important that you familiarise yourself with
the performance and the restrictions of the machine.
It is especially important that the owner, the operator and
those who service the machine are familiar with the
contents of this Instruction Manual and study it thoroughly
before starting and driving, or before any preventive
maintenance work is done.
The responsibility for start, driving and service belongs to
the persons performing these steps! Please make yourself
well familiar with the controls and instructions before the
machine is used. It is too late to start looking in the
Instruction Manual when an accident has already
happened.
NOTICE
In order to find out about manual updates, it is important
to inform Gremo AB of any change of address or owner.

1.3.1 General description of the machine
Fig. 1 Gremo 1250F/1450F
Gremo 1250F/1450F
• is a robust and versatile 12 to 14 tonne forwarder that
easily navigates all types of terrain. The forwarder is
designed and adapted for forwarding timber, the weight
of which does not exceed the machine's maximum load
capacity, from felling site in the forest to the roadside
stacking area.
• is driven by a Cummins QSB 6-cylinder, turbo-charged
6.7 litre diesel engine with intercooler and common rail
fuel system that complies with stage 3B environmental
requirements and is approved for running on
environmentally-friendly fossil-free diesel that complies
with the requirements in EN 15940, e.g. HVO diesel.
• is fitted with Gre-VT, a continual and variable
hydrostatic transmission with 2 speeds that are
controlled by GreControl. Full traction (18.4 tonnes) is
available from the start whatever program is run.
• has electric/hydraulic brakes. Four multi-disc brakes in
oil bath in the front and rear differentials.
• has a load-sensing hydraulic system with hydraulically-
driven variable fan with reversing option to blow out the
coolers controlled by GreControl; the oil is cleaned by a
return filter and a microfilter.
• has a 24 volt electrical system with dual 145 Ah
batteries.

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.

1.5 Operator requirements Gremo 1250F/1450F Workshop 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.
