Before buying a forklift truck, you must make sure that it is well inspected and given a test run. This applies specifically to trucks being purchased on line. It is very essential to find possible problems with trucks obtained from businesses online.
Be certain to start the engine from cold, and note the ease with which the engine turns over and whether there is too much smoke. This is especially crucial with trucks that have IC engines.
Testing the performance of the truck in tough situations should be included in the test run. A skilled driver could drive the truck in reverse and forward, 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 several minutes while a qualified operator tests the hydraulic functions. Afterward, examine the ground underneath for signs of fluid leakage. Even seemingly minor leaking can lead to serious problems that would be really expensive to repair later on.
A qualified individual should inspect the chains and masts. Check with and without a load that the mast works smoothly. Watch for sticking or 'binding' of the mast. A warning indication is play in the mast channels or between the fork carriage and mast. Another is creeping forward or creeping down of the mast when loaded. These could be symptoms of issues with ram, valve or seals.
If the truck is used, the mast may have been changed at some time. Make sure that the mast and any fitted attachments adhere to 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 truck's manufacturer specifies minimum thickness. A loose fit can mean the hanger points or carriage are worn. Watch for cracks on the arms at heels and mountings.
