A forklift must be checked properly and given a test run before buying it. This applies particularly to trucks being acquired on-line. It is very vital to detect possible problems with trucks acquired from businesses online.
Starting the engine from cold is a good idea. Note whether there is too much smoke and the ease with which the engine turns over. This is specifically crucial with IC engine trucks.
The test run should include an inspection of the truck's performance in challenging situations. A qualified 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 a few minutes while a trained driver tests the hydraulic functions. Afterward, look at the ground beneath for indications of fluid leakage. Even seemingly insignificant leaking can lead to serious issues which would be costly to repair later on.
The chains and masts must be inspected by a qualified individual. Check with and without a load that the mast works well. Watch for sticking or 'binding' of the mast. A warning sign is play in the mast channels or between the fork carriage and mast. Another is creeping down or creeping forward of the mast when loaded. These can be symptoms of problems with seals, ram or valve.
The mast might have been changed at some time if the truck is not new. 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.
When checking the forks, look closely at the heel thickness for damage or wear. 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 heels and mountings.
