A forklift should be inspected correctly and given a test run prior to buying it. This applies especially to trucks being acquired online. It is important to find possible problems with trucks bought from businesses online.
Starting the engine from cold is a great idea. Note whether there is too much smoke and the ease with which the engine turns over. This is specifically essential with trucks that have IC engines.
The test run should include a check of the truck's performance in challenging situations. A skilled driver can maneuver the truck in reverse and forward, up the ramp.
You can carry out your own inspection of an IC engine truck. On a clear area of floor, run the truck around for several minutes while a trained operator tests the hydraulic functions. Afterward, look at the ground underneath for indications of fluid leakage. Even seemingly insignificant leaking can indicate serious problems that will be very expensive to repair later on.
The masts and chains should be checked by a qualified individual. 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 signs of issues with valve, seals or ram.
The mast may have been changed at some time if the truck is used. 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 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. Watch for cracks on the arms at mountings and heels.
