Before purchasing a forklift truck, you should make certain that it is properly checked and given a test run. This applies particularly to trucks being purchased on-line. It is important to detect possible issues with trucks obtained from companies 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.
The test run should include a check of the truck's performance in challenging situations. A driver who is qualified could operate the truck in reverse and forward, up the ramp.
You can check an IC engine truck yourself. On a clear part of floor, run the truck around for several minutes while a skilled driver tests the hydraulic functions. Then, examine the ground beneath for indications of fluid leakage. Even seemingly minor leaking can lead to serious issues that will be very expensive to repair later on.
A qualified person must inspect the masts and chains. Check with and without a load that the mast operates 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 forward or creeping down of the mast when loaded. These can be symptoms of problems with valve, seals or ram.
The mast may have been changed at some time if the truck is not new. Make sure that the mast and any fitted attachments adhere to the rating plate on a truck. Make certain 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 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.
