It is our policy and that of our suppliers to constanlly
review the design and capacity of our products. With this
in mind we would remind our customers that while the
dimensions and pertormance data contained herein are
correct at the time of going to press, It is possible that due
to the incorporation of the latest developments to enhance
performance, dimensions and suppliers may vary from
those illustrated.
w
Th is manual is written as a general guide . A typical
machine is shown to illustrate the main features. For
reason of clarity certain guards, safety devices and
machine p~rts may not be shown on particular illustrations
but MUST be fixed to the machine, correctly set and
working before operating.
Failure to comply With instrucllons in this
manual may invalidate the guarantee.
HEALTH AND SAFETY
The CE mark on this maehillC signifies that
an EC dedaration of oonformily is drawn up
indicating that the machine ia manufactured
in accordance with the Essential Health and

Reguletions are not only that the machine
satlslies the relevant assentla l health and
safety requi re men ts, Dut also that 'the

Tho Provision and Uso 01 Work Equipment
Regulations also indude requirements as
PGr sons who install this machine have duties
under Ihe 'Provisi on and Use 01 Work
Equipment Regulations 1992'. An indication
o f these duties Is given In the following
extracts, but lt1e user should be familiar with
the lull Implications ollhe regulations.
REGULATION 5 requires that;
Every employer shall ensure Ihat work
equipment is 50 constrocted Of adapted as to
be suitable for the purpose lor which it is
used or provided.

In selecting work equipment, every employer
shall heve regard to the working conditions
and to the risks to heallh end safety 01
pe rs ons whleh exist in Iho prom i"o" or
undertakings in which tha\ work equ ipment is
to be used and any additional risk posed by
the USII of that work equ ipment.
Every employer shall ensure that work
equipment is used only for the operations lor
which, and under cond itions lor which, it is
suitable.
In lhls regulation 'suitabte' means suitable in

regulation 9 - train ing
Note:-
Attention is drawn 10 those requirements of
the 'Woodworking Machines Regulations
1974' which are 1"101 replaced by the Supply of
M achln ~ry (Safety) Re9ulations or oth~r, ~.g.:
Regulation 13 of the Wooctworking Machinery
Rsgulation, - 'Training', still appj ies.
Whilst the prime duly for Bf1suring health and
safely res ts with emptoyers, employoes too
have legal duties, particularly under sections
7 and a of the Health and Safety at Work Act.
They Include:

correctly all work items provided by the ir
employer in acco rdance with their training
and Ihe Instructions they receive to enabte
them to use the items safely.
Noise
Du s t
Noise levels can vary widely lrom machine to
machine depending 0fI the condilions 01 use.
Persons e~po5ed 10 high noise levels, even
for a short time, may e~perience lemporary
paftial hearing loss and continuous e~posure
to high levels can resu lt i n permanent
hearing damage.
Wood dust can be harmful to hea lth by
and skin contact
and
inhala ti on
cOrlcentratlons cf small particles in the air
can form an explosive mixture.

Heatth Reg ulations (COSHH) 1989 place
legal duties on employers to ensure that:-
The Noi~e at Work RegulatiOns 19139 piece
legal oolies on employers to prevent damage
to hearing.
There are three action levels Of noise delined
in regulatiOfl 2:
The first action lowl:·
a daily personal noise
85dB(A)
e~posure
(LEP'd) of
The second action level;·
a daily personal noise exposure (LEP'd) 01
9()(jB(A)
The peak action level:·
A peak sound pressure of 200 pascals
(14006 re 2Opa)
The exposure level is obviously influenced by
the emission level of all the equipment in use,
w
Emissions levels fOl machines are provided
in the particular madline instruction manual.
These levels are measured in accordallce
with ISO 7960 under certain speclflea test
conditions , they do not necessarily represent
the hlghesl noise level, which is influenced by
many !actors, e,g. number ot epindles in
operalion, type and condition of work piece,
spindle speeds etc.
For regu lations and information on re levant

A flexible pipe con nected the mact1ine to the
dust extraction.
Whilst there is a correlation between
emission levels and e){posure levels. this
cannot be I.lsed reliably 10 determine whether
er net furlher precautions are required 10
ach ieve sElle working levels.
There was no enclosure around the mact1ine.
Machine cunlng criteria
The machine was fitted with a 400mm main
saw rotating at 3000 rpm. The saw blade
had 48 carb ide tipped teeth and a cutting
width of 3,2mm, The blade thickness was
2.2mm.
Facters that illfluence the Elctual leyel of
exposure 10 the werk 10lce include the
durati on of ~posure, Ihe characteristics of
the work room, sources ef noise etc, i.e, the
number of machines and othe r adjacent
prrn;esses. Also the parmissible axposu,e
lavels can vary from country to COl.lntry,
Emissien levels, however, will enable the user
of the mact1ine to make a beller evaluation of
the 'hazard and risk'.
