A forklift must be checked properly and given a test run before purchasing it. This applies particularly to trucks being purchased on-line. It is essential to find potential problems 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 specifically essential with trucks that have IC engines.
Testing the performance of the truck in tough situations should be included in the test run. A skilled operator can 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 part of floor, run the truck around for a few minutes while a trained driver tests the hydraulic functions. Afterward, examine the ground underneath for signs of fluid leakage. Even seemingly minor leaking could indicate serious problems which would be expensive to repair later on.
The masts and chains should be inspected by a trained individual. Check with and without a load that the mast operates smoothly. Watch for sticking or 'binding' of the mast. A warning indication is play in the mast channels or between the mast and fork carriage. One more is creeping down or creeping forward of the mast when loaded. These can be symptoms of problems with ram, valve or seals.
If the truck is not new, the mast might have been changed at some time. Make certain 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 carriage or hanger points are worn. Watch for cracks on the arms at heels and mountings.
