A forklift should be checked properly and given a test run prior to purchasing it. This applies particularly to trucks being acquired on the World Wide Web. It is important to detect possible problems with trucks purchased 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 too much smoke. This is specifically vital with IC engine trucks.
The test run should include an inspection of the truck's performance in challenging situations. A driver who is qualified can drive the truck in forward and reverse, up the ramp.
You could perform your own inspection of an IC engine truck. On a clear part of floor, run the truck around for several minutes while a skilled operator tests the hydraulic functions. After that, examine the ground underneath for signs of fluid leakage. Even seemingly minor leaking could result in serious problems which will be very expensive to repair later on.
A qualified person should inspect the chains and masts. Check with and without a load that the mast operates well. 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 signs of issues with ram, valve or seals.
The mast might have been changed at some time if the truck is used. Make certain 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 inspecting the forks, look closely at the heel thickness for damage or wear. The manufacturer of the truck specifies minimum thickness. A loose fit could mean the hanger points or carriage are worn. Look for cracks on the arms at heels and mountings.
