Before buying a forklift truck, you must make sure that it is correctly inspected and given a test run. This applies especially to trucks being purchased on line. It is very essential to detect potential problems with trucks acquired from businesses on-line.
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 particularly essential with IC engine trucks.
Testing the performance of the truck in challenging situations should be included in the test run. An operator who is qualified can maneuver the truck in reverse and forward, up the ramp.
You can perform your own inspection of an IC engine truck. On a clear area of floor, run the truck around for a few minutes while a qualified driver tests the hydraulic functions. Afterward, examine the ground beneath for indications of fluid leakage. Even seemingly insignificant leaking could indicate serious issues which would be costly to fix later on.
A trained person must inspect 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. One more is creeping down or creeping forward of the mast when loaded. These could be signs of issues with valve, seals or ram.
The mast might have been changed at some time if the truck is used. Make sure that the mast and any fitted attachments follow the rating plate on a truck. Make certain that the sideshift is not sticking when loaded.
When checking the forks, look closely at the heel thickness for wear or damage. The manufacturer of the truck specifies minimum thickness. A loose fit can mean the carriage or hanger points are worn. Watch for cracks on the arms at mountings and heels.
