PREFACE w in w fo .w @ a w dk ad in ki .co n. m co m IMPORTANT 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 Sa fety Requirements of the 'Supply of Machinery (Safely) Regulations 1992.' follows: regulation 6 · malntell3.noo regulation 7 - specific risks regulaMn a - information and insttuc~ons w in w fo .w @ a w dk ad in ki .co n. m co m The 'requirements 101 supply of relevent machinery' in the General Requ irement 01 the Reguletions are not only that the machine satlslies the relevant assentla l health and safety requi re men ts, Dut also that 'the manulacture ..... carries out the necessary research or lests on components , fittings or the complete machine 10 determine wh(lth\!r by its design or construction Ih\! machine is capabts of bslng erected and put Into service safely.' 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. w 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 any respect whi(:h it is reasonab ly foreseaable will affect health or safely of any person. 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: Tak ing reasonabl ~ CSr8 for their own heallh and safety and that 01 oth ers who may be affected by what they do or don't do; co-operating with Iheir employer and safely: on health nol interfering with Of misusing anythi ng provided for their health, safely and welfare. Those dutie6 on employaes have been supp le mented by rogu la\ion 12 ot the Management of Health and Safely at Work Regu lalions '992. One 01 the new raquirements is that employees should use 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. w in w fo .w @ a w dk ad in ki .co n. m co m The COlltrol 01 Substances Hal:ardous to 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 personal protective equipment i. e. ear defenders, employers should reler to the Pe rson a l Protective Equ ipment al Work Regulations 1992. the exposure of his employees to SUbSIElnces hazardous to health is either prevented Of, where this is flOt reasonably prac ticable, adequately controlled. .. .. ad e quate control to e~posure of employees to a sub$tance hazardous to health Shall be secured by measures other than the provision of personal protective equ ipment. where the measures taken in accordance with the para9raph above do not prevant or provide adequate contro l of, exposure to subs tances hal:ardous to tile health of emptoyees, then In addition to tacking those mothods, tho employor shall provide thoso emp loyees with suc h suitab le personal protective equipment as will adequately control their expo sure to substances hazardous to health. In st r uc lfons for Use Machinery manufactures el e required by tile Supply of Machinery Safety Regulations to provide eomprehens ive 'Instruct ions for Use" of equ ipment, it is important that this Information Is transmitted to the person using the machine.
