Before buying a forklift truck, you must make sure that it is properly checked and given a test run. This applies particularly to trucks being bought on line. It is very essential to find 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 especially essential with trucks which have IC engines.
Testing the performance of the truck in tough situations should be included in the test run. An operator who is qualified could operate the truck in forward and reverse, up the ramp.
You could inspect an IC engine truck yourself. On a clear part of floor, run the truck around for several minutes while a qualified operator tests the hydraulic functions. After that, examine the ground beneath for signs of fluid leakage. Even seemingly minor leaking could result in serious problems that will be really expensive to fix later on.
The masts and chains should be inspected by a qualified individual. 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 ram, valve or seals.
The mast may have been changed at some time if the truck is not new. 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 checking the forks, look closely at the heel thickness for damage or wear. The manufacturer of the truck specifies minimum thickness. A loose fit might mean the carriage or hanger points are worn. Watch for cracks on the arms at mountings and heels.
