Operation Manual

VIBRATION
The Eur
opean Physical Agents (Vibration) Directive has been brought in to help reduce
hand
arm vibration syndrome injuries to power tool users. The directive requires power tool
manufacturers and suppliers to provide indicative vibration test results to enable users to make
informed decisions as to the period of time a power tool can be used safely on a daily basis and the
choice of tool. Further Advice can be found at www.hse.gov.uk
Vibration total values (triax vector sum) determined according to EN60335-2-92 and EN13683
Vibration level for operation
Vibration emission value ah = 3.591m/s²
Uncertainty K = 1.5 m/s²
The declared vibration emission value should be used as a minimum level and should be used with
t
he current guidance on vibration.
Calculating the actual period of the actual period off use can be difficult and the HSE website
has further information.
The declared vibration emission been measured in accordance with a standard listed test stated
above and may be used to compare one tool with another. The declared vibration emission value
may also be used in a preliminary assessment of exposure.
WARNING! The vibration emission value during actual use
of the power tool can
differ from the declared value depending on the ways in which the tool is used and
dependant on the following examples and other variations on how the tool is used:
•
How the tool is used and the materials being ground or cut.
•
The tool being in good condition and well maintained.
•
The use of the correct accessory for the tool and ensuring it is sharp and in good
condition. The tightness of the
grip on the handles.
•
And the tool is being used as intended by its design and these instructions.
This tool may cause hand-arm vibration syndrome if its use is not adequately
managed. This tool should not be used for extended periods of time.
WARNING! Identify safety measures to protect the operator that are based on an
estimation of exposure in the actual conditions of use (taking account of all parts of the
operating cycle such as the times when the tool is switched off and when it is running idle in
addition to the trigger time). Note: The use of other tools may reduce or increase the user’s
total working period on this tool. Using another tool with a similar vibration emission would
be equivalent to working for a longer period with this tool, while working with a machine with
no vibration emission might be equivalent to taking a break.
Helping to minimise your vibration exposure risk
Maintain this tool in accordance with these instructions and keep well lubricated (where appropriate).
Avoid using tools in temperatures of 10°C or less.
Plan your work schedule to spread any high vibration tool use across a number of days, or at least
allow for breaks, or time spent using other tools that do not vibrate.
Health Surveillance
All employees should be part of an employer’s health surveillance scheme to help identity any
vibration related diseases at an early stage, prevent disease progression and help employees
stay in work.
