A forklift must be checked properly and given a test run before buying it. This applies specifically to trucks being acquired on line. It is important to find possible issues with trucks purchased from companies on the World Wide Web.
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 particularly crucial with IC engine trucks.
The test run should include an inspection of the truck's performance in challenging situations. An operator who is qualified could maneuver the truck in reverse and forward, up the ramp.
You could inspect an IC engine truck yourself. On a clear part of floor, run the truck around for several minutes while a skilled operator tests the hydraulic functions. Afterward, look at the ground beneath for indications of fluid leakage. Even seemingly insignificant leaking can lead to serious problems that would be costly to repair later on.
A skilled person must check the chains and masts. Check with and without a load that the mast works smoothly. Watch for 'binding' or sticking of the mast. A warning indication is play in the mast channels or between the fork carriage and mast. One more is creeping down or creeping forward of the mast when loaded. These could be symptoms of problems with valve, seals or ram.
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. Make sure that the sideshift is not sticking when loaded.
When checking the forks, look closely at the heel thickness for wear or damage. The truck's manufacturer specifies minimum thickness. A loose fit can mean the carriage or hanger points are worn. Look for cracks on the arms at mountings and heels.
