A forklift must be checked well and given a test run prior to purchasing it. This applies specifically to trucks being bought on the Internet. It is very essential to detect potential issues with trucks obtained from businesses on the Web.
Be sure to start the engine from cold, and note the ease with which the engine turns over and whether there is excessive smoke. This is especially essential with trucks that have IC engines.
The test run must include a check of the truck's performance in tough situations. An operator who is trained can drive the truck in forward and reverse, up the ramp.
You could inspect an IC engine truck yourself. On a clear area of floor, run the truck around for a few minutes while a trained operator tests the hydraulic functions. Then, look at the ground beneath for indications of fluid leakage. Even seemingly insignificant leaking can result in serious problems which will be costly to fix later on.
The chains and masts should be checked by a qualified person. Check with and without a load that the mast operates smoothly. Watch for sticking or 'binding' of the mast. A warning sign is play in the mast channels or between the fork carriage and mast. One more is creeping forward or creeping down of the mast when loaded. These could be signs of problems with ram, valve or seals.
If the truck is used, the mast might have been changed at some time. Make sure that the mast and any fitted attachments follow the rating plate on a truck. Check that the sideshift is not sticking when loaded.
Looking closely at the thickness of the heel for wear or damage should be included in the inspection. The truck's manufacturer specifies minimum thickness. A loose fit can mean the hanger points or carriage are worn. Watch for cracks on the arms at heels and mountings.
