A forklift must be inspected correctly and given a test run prior to buying it. This applies specifically to trucks being obtained on the World Wide Web. It is very important to find possible problems with trucks purchased from companies on-line.
Starting the engine from cold is a good idea. Note whether there is excessive smoke and the ease with which the engine turns over. This is particularly vital with IC engine trucks.
Testing the performance of the truck in challenging situations should be included in the test run. A driver who is trained could drive the truck in reverse and forward, up the ramp.
You can carry out your own inspection of an IC engine truck. On a clear area of floor, run the truck around for several minutes while a qualified operator tests the hydraulic functions. Then, look at the ground underneath for signs of fluid leakage. Even seemingly insignificant leaking can indicate serious problems that would be pricey to repair later on.
A trained person should check the chains and masts. Check with and without a load that the mast works well. Watch for 'binding' or sticking of the mast. A warning sign is play in the mast channels or between the mast and fork carriage. One more is creeping forward or creeping down of the mast when loaded. These can be signs of problems with ram, valve or seals.
The mast might have been changed at some time if the truck is used. Make certain that the mast and any fitted attachments follow the rating plate on a truck. Make certain that the sideshift is not sticking when loaded.
When inspecting the forks, look closely at the heel thickness for wear or damage. The truck's manufacturer specifies minimum thickness. A loose fit might mean the hanger points or carriage are worn. Watch for cracks on the arms at heels and mountings.
