Prior to purchasing a forklift truck, you should ensure that it is properly checked and given a test run. This applies specifically to trucks being purchased online. It is very vital to find potential issues with trucks acquired from companies online.
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 signs of fluid leakage. Even seemingly insignificant leaking can result in serious issues that will be very expensive to fix later on.
The chains and masts must be checked by a skilled person. Check with and without a load that the mast operates well. 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 forward or creeping down of the mast when loaded. These can be symptoms of issues with seals, ram or valve.
If the truck is not new, the mast might have been changed at some time. Make sure that the mast and any fitted attachments follow 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 damage or wear. The truck's manufacturer 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.
