How to Perform Planned Maintenance 7-23
Section 7. Planned Maintenance and Lubrication
Your lift truck cooling system is filled with a factory-
installed solution of 50% water and 50% permanent-type
antifreeze containing rust and corrosion inhibitors. You
should leave the solution in year around. Plain water may
be used in an emergency, but replace it with the specified
coolant as soon as possible to avoid damage to the sys-
tem. Do not use alcohol or methanol antifreeze.
Engine Oil and Filter
Locate the engine oil dipstick. Pull the dipstick out, wipe it with a
clean wiper, and reinsert it fully into the dipstick tube. Remove the
dipstick and check oil level.
It is normal to add some oil between oil changes. Keep the oil level
above the ADD mark on the dipstick by adding oil as required. Do not
overfill. Use the correct oil as specified under Lubricant Specifications.
It is recommended to:
• Drain and replace the engine crankcase oil every 500 oper-
ating hours. (depending on application). See NOTICE
• Engine Oil Filter must be changed at every PM when the oil
is changed.
• 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.
Engine oil at operating temperature is hot and can cause
burns. Beware of splashing oil.
• Carefully check for leaks after changing oil and installing
new filter.
The time interval for changing engine oil depends upon
your application and operating conditions. To determine
the correct schedule for your truck, it is suggested that
you periodically submit engine oil samples to a commer-
cial laboratory for analysis of the condition of the oil.
