Before buying a forklift truck, you should make sure that it is properly inspected and given a test run. This applies especially to trucks being bought on-line. It is really important to detect possible problems with trucks obtained from companies online.
Starting the engine from cold is a great idea. Note whether there is excessive smoke and the ease with which the engine turns over. This is specifically crucial with IC engine trucks.
The test run should include an inspection of the truck's performance in challenging situations. A driver who is qualified can drive the truck in forward and reverse, up the ramp.
You can inspect an IC engine truck yourself. On a clear area of floor, run the truck around for several minutes while a skilled driver tests the hydraulic functions. Afterward, look at the ground underneath for signs of fluid leakage. Even seemingly insignificant leaking could indicate serious issues which would be costly to fix later on.
The masts and chains must 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 sign is play in the mast channels or between the mast and fork carriage. Another is creeping forward or creeping down of the mast when loaded. These can be signs of issues with ram, valve or seals.
The mast might 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 sure that the sideshift is not sticking when loaded.
When checking the forks, look closely at the heel thickness for damage or wear. The manufacturer of the truck 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.
