Container (1 qt [0.9 1] minimum capacity)
Engine running at low idle
General Safety Instructions
Hydraulic system at operating temperature
Avoid prolonged skin contact wit hydraulic oil.
Drum and wheels chocked
Work in a well-ventilated area.
· Do not drain hydraulic oil while oil is hot. Severe injury to personnel may result.
· Prolonged contact with lubricating oil, MIL-L-2104, may cause a skin rash. Skin and
clothing that come in contact with lubricating oil should be thoroughly washed
immediately. Saturated clothing should be removed immediately. Areas in which

· Oil is slippery and can cause falls. To avoid injury, wipe up all spilled oil with rags.
· There is no clearance for personnel between frame and yoke when Roller turns. Severe
injury or death from crushing could occur.
· Steering fame must be locked before lifting, transporting, or servicing Roller in
articulation area with engine running to prevent serious injury or death from crushing.
· Unlock steering frame before operation to prevent loss of steering that may cause serious
injury or death to personnel.
· When working on a running engine, provide shielding for exposed rotating parts. Tools,
clothing, or hands can get caught and cause serious injury to personnel.
Sample hydraulic oil with the oil warm, not HOT, to allow for draining of waste particles that
are suspended in oil. As oil cools, suspended particles settle on the bottom of the hydraulic
reservoir and cannot be removed by draining the oil. Failure to follow this recommendation
procedure can result in disproportionate sample collection.
