I would also like to note that no one should ever attempt to operate a forklift until you have been _properly_ trained, and since one of the OSHA requirements of proper operator training is how to replenish the power supply [either correctly refuel and internal combustion powered unit or correct (safe) recharging and servicing batteries in a motive battery powered unit] I would hope you would insist that your employer provide you with a -full- course in safe forklift operation. 29CFR1910.178(l)(3)(i)(K) and 29CFR1910.178(g)
