If the forklift you are referring to is in your profile picture and it is a high lift model then it is in violation of 29 CFR 1910.178(e)(1).
I can't even go on a service call on those old, non-compliant trucks. I highly advise you to get rid of it by way of a salvage yard and find an up to date truck that will keep its operator from getting killed and keep its owner from being sued.
