6.2 MAINTENANCE AND LUBRICATION
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 vehicle. The following
Lubricant Chart shows the proper lubricant and the most common brands and
specification which meet the requirements. Refer to Section 6.3.
The hydraulic filter located on the return side of the hydraulic tank comes equipped
with restriction indicator gauges. The gauge shows 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 filter element will result in
premature wear and/or failure of any or all of the hydraulic components. Only check
gauge when hydraulic fluid is at operating temperature. Cold oil is more dense and
will give a false indicator gauge reading. Refer to Section 6.6.
For all sling, strap, chain and lifting components refer to the manufacturer inspection
and maintenance schedules.
