A forklift must be checked well and given a test run before buying it. This applies specifically to trucks being purchased online. It is really essential to find possible issues with trucks purchased from businesses on the Internet.
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 specifically essential with trucks which have IC engines.
Testing the performance of the truck in tough situations must be included in the test run. An operator who is trained can drive the truck in reverse and forward, up the ramp.
You could check an IC engine truck yourself. On a clear area of floor, run the truck around for several minutes while a skilled operator tests the hydraulic functions. Then, look at the ground beneath for indications of fluid leakage. Even seemingly insignificant leaking could lead to serious issues that would be pricey to repair later on.
A skilled individual should inspect the chains and masts. Check with and without a load that the mast operates well. Watch for 'binding' or sticking of the mast. A warning indication 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 symptoms of issues with valve, seals or ram.
If the truck is used, the mast might 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.
Looking closely at the thickness of the heel for wear or damage must be included in the inspection. The truck's manufacturer 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.
