Before purchasing a forklift truck, you should make sure that it is correctly inspected and given a test run. This applies specifically to trucks being bought on the World Wide Web. It is really vital to find potential issues with trucks purchased from companies on the Web.
Starting the engine from cold is a great idea. Note whether there is too much smoke and the ease with which the engine turns over. This is especially vital with trucks which have IC engines.
Testing the performance of the truck in tough situations should be included in the test run. A skilled driver can drive the truck in forward and reverse, up the ramp.
You can perform your own inspection of an IC engine truck. On a clear area of floor, run the truck around for a few minutes while a skilled driver tests the hydraulic functions. After that, look at the ground beneath for signs of fluid leakage. Even seemingly minor leaking can result in serious problems that will be costly to repair later on.
The masts and chains should be checked by a skilled person. Check with and without a load that the mast operates well. Watch for sticking or 'binding' of the mast. A warning indication is play in the mast channels or between the fork carriage and mast. One more is creeping forward or creeping down of the mast when loaded. These can be symptoms of problems with valve, seals or ram.
The mast may have been changed at some time if the truck is used. 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 hanger points or carriage are worn. Look for cracks on the arms at heels and mountings.
