A forklift should be checked correctly and given a test run prior to buying it. This applies especially to trucks being bought online. It is important to find possible issues with trucks bought from businesses on the World Wide Web.
Be sure to start the engine from cold, and note the ease with which the engine turns over and whether there is excessive smoke. This is specifically essential 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 drive the truck in reverse and forward, up the ramp.
You can check an IC engine truck yourself. On a clear area of floor, run the truck around for several minutes while a qualified operator tests the hydraulic functions. Then, examine the ground underneath for signs of fluid leakage. Even seemingly minor leaking can indicate serious problems that will be costly to fix later on.
The chains and masts should be inspected by a qualified person. Check with and without a load that the mast works smoothly. Watch for 'binding' or sticking 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 symptoms of issues with valve, seals or ram.
If the truck is not new, the mast may have been changed at some time. Make certain 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 damage or wear should be included in the inspection. The manufacturer of the truck specifies minimum thickness. A loose fit can mean the hanger points or carriage are worn. Look for cracks on the arms at mountings and heels.
