Prior to purchasing a forklift truck, you should make certain that it is properly checked and given a test run. This applies especially to trucks being obtained on-line. It is important to detect possible issues with trucks bought from businesses online.
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 vital with IC engine trucks.
The test run must include a check of the truck's performance in challenging situations. An operator who is qualified can drive the truck in reverse and forward, up the ramp.
You could 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 trained driver tests the hydraulic functions. Then, look at the ground beneath for indications of fluid leakage. Even seemingly minor leaking could result in serious issues that would be very expensive to repair later on.
The masts and chains must be checked by a trained individual. Check with and without a load that the mast works smoothly. Watch for 'binding' or sticking of the mast. A warning sign 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 can be symptoms of issues with valve, seals or ram.
If the truck is used, the mast might have been changed at some time. Make certain that the mast and any fitted attachments follow 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 might mean the carriage or hanger points are worn. Watch for cracks on the arms at mountings and heels.
