TM 5-3895-373-10 2.27.2 Cold Weather Operations. a. Use    the    following    steps    to    start    the    paving machine at temperatures below 50°F (10°C). (1) Turn   the   ignition   switch   to   the   preheat position  and  hold  for  10  seconds  to  heat the induction heater. CAUTION Starter motor may overheat if operated  longer  than  30  seconds.    If engine   does   not   start,   allow   starter motor     to     cool     for     two     to     three minutes before trying again.  If engine fails    to    start    after    three    attempts, notify Unit Maintenance. (2) Turn the ignition switch to the start position and immediately release when the engine starts.  The switch will spring return to the ON position. b.    Maximum extreme cold temperature for machine operation is -50°F (-46°C). NOTE Paving    machine    operation    will    be sluggish until the hydraulic oil reaches normal operating temperature. c.    If  the  machine  will  start  at  temperatures  higher than    -50°F    (-460C),    the    machine    can    be operated  after  the  engine  coolant  temperature starts  to  rise  at  the  gauge  panel  temperature gauge.  Other non-propulsion hydraulic functions cannot be operated until hydraulic oil temperature  reaches  100°F  (38°C).    No  other special operating procedures are required. 2-98 2.27.3  Extreme Dusty and Sandstorm Conditions. a.    Under   extreme   wind   driven   dust   conditions, check   air   cleaner   service   indicator   every   1/2 hour of operation. b.    Service  the  air  cleaner  per  table  2-1,  Operator PMCS, twice daily. c.    Replace air cleaner filter element per paragraph 3.3.7    after    every    50    hours    of    continuous operation in extreme dusty conditions. WARNING Death or serious injury could occur if compressed   air   is   directed   against skin.    Do  not  use  compressed  air  for cleaning or drying unless the pressure   is/was   reduced   to   30   psi (207 kPa) or less.  When working with compressed    air,    always    use    chip guards,    eye    protection,    and    other personal protective equipment. d.    Use   compressed   air   to   blow   out   all   dirt   and debris from hydraulic oil cooler and radiator. e.    The  paving  machine  shall  not  be  operated  in  a sandstorm.    Take  the  following  precautions  to protect   the   machine   from   damage   during   a sandstorm. (1) Ensure  extension  screeds  are  retracted, hopper  wings  are  open,  and  screed  is  in travel   position   to   protect   cylinder   shafts from abrasive blowing sand. (2) Coat  chrome  guide  shafts  on  screed  with a  heavy  coat  of  automotive  and  artillery grease (Item 5, Appendix D). (3) Cover    air  cleaner  cap    assembly    with sheet plastic. (4) Install     protective     covers     on     operator console and screed crew control boxes. (5) Close all access doors and covers. 2.27.4    High  Altitude  Operation.    The  paving  machine diesel   engine   has   a   considerable   amount   of   reserve horsepower   to   compensate   for   machine   operation   at altitudes up to 10,000 ft (3050 m).  If engine bogs down at  high  altitude,  reduce  paving  speed  until  engine  runs smoothly. 2-98
