TM 5-3805-260-10 7. Transmission  oil  should  show  on  the  dipstick.    Add oil if necessary. 8. Check  the  hydraulic  oil  level  with  the  bowl  lowered. The  level  must  be  above  the  ADD  mark  on  the  sight gauge, or on the dipstick in the fill opening. 9. Visually check the tires  for  cuts,  gouges  and  proper inflation. WARNING Improperly  inflated  tires  can  cause  excessive  heat buildup, resulting in blowouts. CAUTION Over  or  under  inflated  tires  can  cause  excessive  or uneven tire wear, or rim damage. Keep the valve caps on to prevent dirt from entering the valve stems.  Otherwise valve damage can occur. Consult   your   tire   dealer   for   the   correct   operating   tire pressure for your operating conditions. Measure  the  tire  pressure  if  a  tire  appears  improperly inflated.        Check    the    tire    pressure    cold,    at    outside operating temperature. WARNING Use a self attaching air chuck and stand behind  the tread of the tire when inflating.
