A forklift should be checked correctly and given a test run prior to buying it. This applies especially to trucks being obtained on the Internet. It is really vital to detect possible problems with trucks obtained from businesses on-line.
Be certain to start the engine from cold, and note the ease with which the engine turns over and whether there is excessive smoke. This is particularly crucial with IC engine trucks.
Testing the performance of the truck in challenging situations must be included in the test run. A trained operator can operate the truck in forward and reverse, up the ramp.
You can carry out your own inspection of an IC engine truck. On a clear part of floor, run the truck around for a few minutes while a skilled operator tests the hydraulic functions. Afterward, look at the ground underneath for indications of fluid leakage. Even seemingly minor leaking could result in serious problems that will be very costly to repair later on.
A qualified person should check the masts and chains. Check with and without a load that the mast works well. Watch for sticking or 'binding' 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. Check that the sideshift is not sticking when loaded.
When checking the forks, look closely at the heel thickness for damage or wear. The truck's manufacturer specifies minimum thickness. A loose fit could mean the hanger points or carriage are worn. Watch for cracks on the arms at mountings and heels.
