TM 5-3895-373-20 15.6. REPLACE HOPPER LIFT CYLINDER - Continued A. REMOVE - Continued. The hopper wing weighs 875 lbs (397 kg).    Ensure  hoist  and  slings  are  in good    working    condition    and    have adequate   lifting   capacity   to   support hopper wing.  Failure to use adequate lifting equipment may result in serious injury or death. e. Using the hoist, raise hopper wing as needed to provide access to hopper lift cylinder (6). 2. DISCONNECT HOPPER LIFT CYLINDER HOSES. Cleaning  solvent,  P-D-680,  is  TOXIC and     flammable.          Wear     protective goggles  and  gloves.    Use  only  in  a well   ventilated   area.      Avoid   contact with  skin,  eyes,  and  clothes,  and  do not breathe vapors.  Keep away from heat   or   flame.      Never   smoke   when using solvent; the flashpoint for Type III cleaning solvent is 2000F (93,30C). Failure  to  do  so  may  result  in  injury or death to personnel. If     personnel     become     dizzy     while using   cleaning   solvent,   immediately get   fresh   air   and   medical   help.      If solvent    contacts    skin    or    clothes, flush    with    cold    water.        If    solvent contacts  eyes,  flush  eyes  with  water and get immediate medical attention. Thoroughly  clean  hoses  and  fittings before  disconnecting.    Always    plug or    cap    off  disconnected  fittings  to prevent    intrusion    of    contaminants. Failure  to  properly  clean  and  cap  off connectors    may    result    in    system contamination and equipment damage. a. Use    cleaning    cloth    moistened    with    cleaning solvent  to  clean  all  dust,  dirt,  and  oil  or  grease residue from hose ends and fittings at hopper lift cylinder (6). b. Tag  lower  cylinder  hose  "inlet"  and  upper  hose "outlet". c. Place drip pan (7) below hydraulic hoses (8 and 9). Hydraulic oil can be moderately flammable  and  can  be  an  irritant  to the skin, eyes, and respiratory system.    Avoid  prolonged  exposure. Eye    protection    and    rubber    gloves must   be   worn   when    working    with hydraulic oil. d. Disconnect    hydraulic    hoses    (8    and    9)    from hopper   lift   cylinder.      Drain   hydraulic   oil   from hoses into drip pan.  Dispose of waste hydraulic oil in accordance with local procedures.
