A forklift must be inspected correctly and given a test run before purchasing it. This applies specifically to trucks being bought online. It is vital to detect possible issues with trucks purchased 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 too much smoke. This is especially crucial with IC engine trucks.
The test run should include an inspection of the truck's performance in challenging situations. A driver who is trained can operate the truck in reverse and forward, up the ramp.
You could check an IC engine truck yourself. On a clear part of floor, run the truck around for a few minutes while a qualified driver tests the hydraulic functions. Afterward, examine the ground underneath for signs of fluid leakage. Even seemingly insignificant leaking can result in serious issues that would be costly to repair later on.
A trained person should 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 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 could be signs of problems with seals, ram or valve.
If the truck is not new, the mast may have been changed at some time. 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 wear or damage. The manufacturer of the truck specifies minimum thickness. A loose fit might mean the carriage or hanger points are worn. Look for cracks on the arms at heels and mountings.
