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.

Gremo 1250F/1450F Workshop manual
• If there are any unauthorised people or vehicles within
the machine's operating area.
• 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.

2.10 Driving
2.10 Driving
The working speed is set between 1,200-1,500 rpm in the
Control System GreControl/IQAN monitor.
As soon as you start to use the crane levers the working
speed is activated, and when you release the crane levers
the revs reduce to an increased idle after the time delay
selected in GreControl. This occurs when the seat is facing
backwards towards the crane/gate.
Driving on public roads
When driving on public roads with other traffic, the steering
wheel must always be used, and the terrain driving
function must be turned off.
Driving speed
A Gremo 1050F is designed to manage a maximum load
of 10,500 kg, even on difficult terrain. Off-road driving
causes large dynamic forces on the machine. The
machine’s own weight, plus the load, increases the stress
in its construction if driven carelessly over difficult terrain.
By driving gently, with feeling and understanding, you can
avoid costly repairs and downtime.
Fig. 19 Overload
Uphill
When driving uphill, the centre of gravity of the payload is
shifted backwards, exerting a lifting force on the front
carriage. If the machine is angled severely in this situation,
it can tip over..
Downhill
The load’s centre of gravity is moved forward when driving
down a slope, and exerts a pushing force on the engine. If
the machine is angled severely in this situation, it can tip
over..
NOTICE
Never load over the top of the gate!
Overloading leads to worse stability, and during downhill
driving the timber may slide over the gate and damage
the machine.
