A forklift should be inspected correctly and given a test run before purchasing it. This applies especially to trucks being acquired on the World Wide Web. It is important to detect possible issues with trucks bought from companies on-line.
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 particularly crucial with trucks that have IC engines.
Testing the performance of the truck in tough situations must be included in the test run. A skilled driver could maneuver the truck in forward and reverse, up the ramp.
You can inspect an IC engine truck yourself. On a clear part of floor, run the truck around for several minutes while a trained driver tests the hydraulic functions. After that, examine the ground beneath for signs of fluid leakage. Even seemingly minor leaking could indicate serious problems that will be really costly to repair later on.
A skilled individual must inspect the masts and chains. Check with and without a load that the mast works well. Watch for sticking or 'binding' of the mast. A warning sign 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 can be signs of problems with seals, ram or valve.
The mast may have been changed at some time if the truck is not new. 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.
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 could mean the carriage or hanger points are worn. Watch for cracks on the arms at heels and mountings.
