I'd really appreciate a little help. When I turn on my Caterpillar M50 forklift, the red "lockout" light on the battery life gauge stays red and none of the functions are responding, except the forward lights.

We are a one man business and this is my first and only forklift, and I quite simply might be forgetting a simple step (turn the forklift on in neutral, with the hand brake on, and standing on the foot brake. Release the hand brake then switch to forward or reverse and all fork operations should respond- right? Or did I quite simply forget a basic start up step?).

Thanks so much,
Joe, Denver, CO
