MAINTENANCE AND LUBRICATION
Your MPL has been designed to give you excellent service and long life but
like all equipment, it requires proper and periodic maintenance. The truck
chassis itself is on a maintenance schedule recommended by the
manufacturer. Follow these guidelines and protect your vehicle warranty.
There are a number of different lubricants used on your MPL and the following
chart details the proper lubricant and the most common brands and
specification which meet the requirements.
Use only safe practices when maintaining this equipment. Always shut off
the engine before reaching into pinch areas.
Inspect the vehicle and underlift system periodically for damage or evidence
of pending failure. Damaged or broken parts should be replaced immediately.
Never operate a machine which is known to be defective or operating
improperly. The cause of any binding or leakage should be determined
immediately and the problem promptly fixed.
Your MPL has Jerr-Dans “No-Lube” maintenance-free pivot joint system.
Most of the pivot joints utilize high strength composite bearings with
hardened and plated pins to drastically reduce maintenance, down-time
and the cost of lubrication over the life of the product. There are however a
few areas that still require some lubrication or maintenance. Sliding surfaces
should be cleaned periodically. The following chart and diagram shows the
location of these points, and when and what type of lubricant to use.
Check the hydraulic oil level bi-monthly or after any leakage. A visual sight
gauge has been located on the driver’s side of the hydraulic tank. The proper
oil level is best checked with all cylinders fully retracted. Use a Super
Premium Grade Multi-Viscosity hydraulic oil. (See Chart) (Automatic
transmission fluid may be used in the hydraulic system if necessary.)
The hydraulic filter located on the return side of the hydraulic tank comes
equipped with a restriction indicator gauge. This gauge shows the operator
the condition of the filter element. When the needle reaches the red band
(25 psi), the filter is starting to bypass and the element needs to be changed.
Failure to change the element will result in premature wear and/or failure of
any or all of the hydraulic components. Check gauges when the hydraulic
fluid is at operating temperatures. Cold oil is more dense and will
give a false indicator gauge reading.
