Thwaites Limited puts Safety First
It is the policy of Thwaites Limited to promote safety in the
operation of its machines and to create a general awareness of
site safety and safe working practices for the operators of its
machines.
This Operator’s Instruction Manual is intended for both new
and experienced machine operators. It should remain with
the machine at all times. All operators should be aware of its
location and contents.
It is important that all operators are fully trained and familiar
with the machine and that they have read and understood the
information contained within this book before they attempt
to operate in the site conditions for which the machine was
designed.
This book details practices and operations which Thwaites
Limited recommends. DO NOT operate this machine in ways
other than those detailed within this book.
This machine is designed for customary construction site
operations, and the transportation of bulk materials commonly
carried on such sites; that is their ‘intended use’. Under certain
controlled conditions the dumper may be used for towing
wheeled loads.
Due to the varied nature of the operation of site dumpers and
the absence of an agreed test standard, any gures quoted
by Thwaites in relation to vibration values and exposure are
for reference purposes only. It is the responsibility of the
employer to assess vibration exposure based on the actual site
conditions, and operating practices, at the point of use.
Hand Arm Vibration - The daily exposure Action/Limit Values
of between 2.5 - 5.0m/s2 (A8) are unlikely to be exceeded in an
eight-hour reference period.
Whole Body Vibration - The daily exposure can only be
accurately determined at the point of use. This exposure must
be managed in respect of the Action/Limit Values of 0.5 and
1.15 m/s2 (A8) respectively.
Employers should not rely solely on published vibration
gures when undertaking risk assessments. Depending on the
site conditions, cycle times may need to be adjusted in order
to reduce operator exposure levels.
Vibration values based on typical duty cycles are available
on request from Thwaites. These may be used for reference
purposes only.

VISIBILITY
The visibility maps show machines in standard build and travel
conguration.
The maps provide an approximate indication of what can be seen
by the operator and any blind spots when seated in the driving
position wearing a seatbelt.
The maps have been provided to assist the operator / user and
may be used as part of a risk assessment for the safe operation of
the machine.
The machines are compliant with the visibility requirement given
in EN 474-1 with regards to the rectangular boundary and a test
object of 1.2m high and 0.3m wide and the 12m circular boundary.
• Check all around the machine before operation.
• Be sure all mirrors are adjusted before operating the machine
(if tted).
• All cameras and mirrors must be kept clean (if tted).
• Be aware of all blind spots.
The blind spot areas marked on the plan views of these maps are
ground plane only
WARNING
Camera angles are factory set, any modications to the machine
conguration by any end user that my result in the restriction of
visibility and will require a new risk assessment to be performed. Operators eld of vision
