I have just got a Hymac 270 (least I presume it is a 270 as serial number is 178-270) and am trying to find an operator manual and/or workshop manual.

Does anyone have any ideas where I might be able to get one?

Engine c439510
Power unit no: B916197
Chassis number: 68

Any advice or information would be appreciated.

Thanks,

Rob
