Prior to purchasing a forklift truck, you should make sure that it is correctly inspected and given a test run. This applies especially to trucks being purchased online. It is vital to detect possible problems with trucks acquired 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 IC engine trucks.
Testing the performance of the truck in challenging situations must be included in the test run. A skilled operator could maneuver the truck in reverse and forward, up the ramp.
You could perform your own inspection of an IC engine truck. On a clear part of floor, run the truck around for a few minutes while a qualified driver tests the hydraulic functions. After that, look at the ground underneath for indications of fluid leakage. Even seemingly insignificant leaking could indicate serious issues which would be really expensive to fix later on.
The masts and chains must be checked by a qualified person. 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 fork carriage and mast. One more is creeping down or creeping forward of the mast when loaded. These could be signs of problems with valve, seals or ram.
If the truck is not new, 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.
When inspecting the forks, look closely at the heel thickness for wear or damage. The truck's manufacturer specifies minimum thickness. A loose fit can mean the carriage or hanger points are worn. Look for cracks on the arms at mountings and heels.
