A forklift should be checked correctly and given a test run prior to purchasing it. This applies particularly to trucks being acquired on the World Wide Web. It is really important to find possible issues with trucks obtained from companies on-line.
Be certain to start the engine from cold, and note the ease with which the engine turns over and whether there is excessive smoke. This is especially vital with trucks that have IC engines.
Testing the performance of the truck in tough situations must be included in the test run. An operator who is trained could maneuver the truck in forward and reverse, up the ramp.
You could carry out your own inspection of an IC engine truck. On a clear area of floor, run the truck around for a few minutes while a trained operator tests the hydraulic functions. Afterward, look at the ground beneath for signs of fluid leakage. Even seemingly minor leaking could indicate serious problems which would be really costly to fix later on.
The masts and chains must be checked by a skilled person. Check with and without a load that the mast works well. Watch for 'binding' or sticking of the mast. A warning indication 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 could be symptoms of problems with valve, seals or ram.
If the truck is not new, 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.
When inspecting the forks, look closely at the heel thickness for wear or damage. The truck's manufacturer specifies minimum thickness. A loose fit can mean the carriage or hanger points are worn. Look for cracks on the arms at mountings and heels.
