LUBRICATION INSTRUCTIONS
1. GENERAL
NOTE
These instructions are mandatory.
at recommended intervals in order to be mission-ready at all times.
b. The Lubrication Chart shows lubrication points, items to be lubricated, the required lubricants,
and recommended intervals for lubrication. Any special lubrication instructions required for
specific components are contained in the NOTES section of the chart.
c. The KEY provides information needed to select the proper lubricant for various temperature
ranges and uses, and identifies the capacities and intervals.
d. Recommended intervals are based on normal conditions of operation, temperature, and
humidity. When operating under extreme conditions, lubricants should always be changed more
frequently. When in doubt, notify your supervisor.
2. SPECIFIC LUBRICATION INSTRUCTIONS
a. Keep all lubricants in a closed container and store in a clean, dry place away from extreme heat.
Keep container covers clean and do not allow dust, dirt, or other foreign material to mix with
lubricants. Keep lubrication equipment clean and ready for use.
b. Maintain a record of lubrication performed and report any problems noted during lubrication.
Refer to DA Pam 738-750 for maintenance forms and procedures to record and report any
c. Keep all external parts of equipment not requiring lubrication free of lubricants. After lubrication,
wipe off excess lubricant to prevent accumulation of foreign matter.
3. ARCTIC PROCEDURE
NOTE
This procedure is to be used from -20F to -50F.
As oil viscosity varies with temperatures, it will be required to change the hydraulic fluid to
OHA 5606 Arctic hydraulic fluid. Following the oil change procedures (ref: WP 0056) it will be necessary
to adjust the hydraulic flow valve for the boom and the mast functions located on the vertical slide section.
Turn the control knob of the hydraulic flow valve clockwise to restrict flow; counter-clockwise to increase
volume size to obtain 300-800 lbs. system hydraulic pressure while the boom function is lowered with no
load attached. In the same way, adjust the mast hydraulic flow valve when the mast is being lowered with
no load attached. This may need to be readjusted as necessary as temperatures vary from -50F to
120F or when OHA 5606 is replaced with standard hydraulic fluid.
When the fifth wheel towing device is exposed to a temperature increase from -25F or below to
10F, the functions should not be left under pressure and it is recommended that each function be
operated at 10F to release pressure created by expansion caused by an increase in temperature.
