also  u will on quite few times need 100ft hose, and u will need ext leads trust me, all my machines hav 50ft leads , do not use ord ext leads do not plug two machine plugs into one ext lead , the reasons for this is u will melt the plugs in the socket in the house,u will melt the ext lead socket ,  go buy yourself  2 lots of 50ft very heavy duty lead from a proper sparky shop and fit heavy duty sockets an plugs ,   remeber these machines leads each are drawing near on the max 3200 watts u can get out of a household socket 
p.s kev if u hav only 50ft of hoses  u need to phone your supplier asp and order 2 extra 25 ft lenghs  or u could be in trouble on u first job !!
