A forklift must be checked well and given a test run before purchasing it. This applies especially to trucks being bought on-line. It is vital to find potential issues with trucks bought from companies on the Internet.
Be sure to start the engine from cold, and note the ease with which the engine turns over and whether there is too much smoke. This is specifically crucial with trucks which have IC engines.
Testing the performance of the truck in tough situations should be included in the test run. A trained operator could maneuver the truck in forward and reverse, up the ramp.
You can perform your own inspection of an IC engine truck. On a clear area of floor, run the truck around for several minutes while a skilled operator tests the hydraulic functions. After that, examine the ground underneath for signs of fluid leakage. Even seemingly minor leaking can result in serious issues that will be pricey to repair later on.
The chains and masts must be inspected by a skilled individual. Check with and without a load that the mast works well. Watch for sticking or 'binding' of the mast. A warning indication is play in the mast channels or between the mast and fork carriage. Another is creeping down or creeping forward of the mast when loaded. These could be symptoms of issues with ram, valve or seals.
If the truck is used, the mast may 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 damage or wear should be included in the inspection. The truck's manufacturer specifies minimum thickness. A loose fit might mean the carriage or hanger points are worn. Look for cracks on the arms at heels and mountings.
