Walk around the truck and take note of any obvious damage or
maintenance problems.
Check to be sure all capacity, safety, and warning plates are
attached and legible.
NOTICE
NAME PLATES AND DECALS: Do not operate a lift truck
with damaged or lost decals and nameplates. Replace
them immediately. They contain important information.
Inspect the truck, before and after starting the engine, for any sign of
external leakage of fuel, engine coolant, transmission fluid, etc.
Check for hydraulic oil leaks and loose fittings.

HYDRAULIC FLUID PRESSURE: Do not use your hands to
check for hydraulic leakage. Fluid under pressure can
penetrate your skin and cause serious injury.
Changing the Engine Oil and Oil Filter
Remove the filter cartridge.
Lightly grease the sealing ring on the
new filter cartridge and screw in the
cartridge until it is hand tight.
Remove the oil pan drain plug to
drain old oil after the truck has been
in operation and the engine (oil) is at
operating temperature.
Carefully check for leaks after changing oil and installing new filter.
