Operator and maintenance manuals for all Yale forklift models are available for order from the company, but they require orders to be placed through a Yale distributor. There is a distributor locating tool on the Yale website. Many manuals can be purchased online at places such as UManuals and eBay.
OSHA regulation 29 CFR 1910.178(q)(7) requires that all lift trucks be inspected before the start of each shift. A mandatory component of this inspection is that a legible operator manual be attached to every forklift. A replacement for any manual that has been lost, or damaged, should be procured to maintain compliance.
