Air Cleaner NOTE Air    cleaner    should    not    be    serviced    unless    the    air restriction  indicator   shows   service   is   required.   Do   not “over-service”. 1.    Check air cleaner mounting and connections. Be sure the air cleaner hose is securely connected (not loose or leaking). 2.    Inspect the engine air filter element for damage and  contamination  (excessive  dirt  build-up  and clogging). When replacing the  air  filter  element, always   inspect   the   air   intake   passages   for evidence  of  dirt.  Clean  (wipe  out)  the  housing. Change  the  engine  air  filter  every  50  to  250 hours,    depending    upon    the    application    and operating conditions, except as noted below. Battery Do  not  smoke  or  have  open  flames  or sparks  in  battery  charging  areas  or  near batteries.   An   explosion   can   result   and cause injury or death. This battery contains corrosive acid which can   cause   injury.   If   acid   contacts   your eyes or skin, flush immediately with water for 15 minutes and get medical assistance. 1.    Inspect the battery and mounting. Check battery cables for wear. Be sure the cable terminals are tight and clean. 2.    Inspect   the   battery   for   any   damage,   cracks, leaking    condition,    etc.    If    the    terminals    are corroded, clean and protect them. If your battery has removable vent caps, check to be  sure  the cells  are  all  filled.    Refill  with  distilled  water  to bottom of vent cap opening. 3.    Be  sure  vent  caps  (as  applicable)  are  properly sealed in battery top to avoid spillage. Functional Tests Check   that   all   controls   and   systems   are   functioning correctly. Safety Equipment Damage  to  the  truck  can  result  if  any  of  the  warning indicators illuminate when the engine is running. Stop the engine. Do not operate the truck. Report any failures. NOTE To  avoid  starting  engine  when  checking  warning  lights, move  directional  control  lever  from  'N"  (neutral)  briefly only, while turning key switch to START position. 1.    Test horn, lights, and all other safety equipment and   accessories.   Be   sure   they   are   properly mounted and working correctly. 2.    Press horn button to check horn function.
