Does anyone have an operators manual loaded on their computer and could e-mail it to me. It would be greatly appreciated. Thanks, CEC271
I don't have one on computer but may have a paper version at work I'll try to remember to check on Monday and let you know. Are there any questions I could answer for now? most of ours were 1845's but should be very close to your 1840. 1840 is a gas engine version if I recall.
