A forklift must be inspected correctly and given a test run before purchasing it. This applies particularly to trucks being acquired online. It is really important to find possible issues with trucks obtained from businesses on the Web.
Be sure 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 vital with IC engine trucks.
Testing the performance of the truck in tough situations should be included in the test run. A driver who is trained can maneuver the truck in reverse and forward, up the ramp.
You could inspect 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. Afterward, examine the ground beneath for indications of fluid leakage. Even seemingly insignificant leaking can result in serious problems which will be very pricey to fix later on.
A trained individual should check the chains and masts. 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 mast and fork carriage. Another is creeping down or creeping forward of the mast when loaded. These could be symptoms of problems with seals, ram or valve.
The mast may have been changed at some time if the truck is not new. Make certain that the mast and any fitted attachments follow the rating plate on a truck. Make sure 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 could mean the hanger points or carriage are worn. Look for cracks on the arms at heels and mountings.
