TM 10-3930-669-10 2-12.  UNUSUAL ENVIRONMENT/WEATHER (CONT). (3) Drain fuel filter and fuel/water separator before filling fuel tank to prevent any water in fuel from freezing. This will also prevent fuel filter from clogging. (4) Keep fuel tank as full as possible during cold operations. (5) Press glow plug button and hold for 10 to 15 seconds.  In severely cold weather 0°  and below, increase glow plug time up to 60 seconds before attempting to start engine. NOTE If  engine  fails  to  start  within  10  seconds,  discontinue  cranking  and  wait  15  seconds  before  next attempt to allow starter motor to cool.  Repeat Step (5). (6) Start engine (Para 2-10.  d.) and allow it to warm up to normal operating temperature. (7) Slowly raise and lower mast assembly to allow hydraulic fluid to warm up. WARNING Icy roads and surfaces are common during periods of severe cold.  Care should be exercised when operating on icy surfaces.  Sudden movements or lack of attention can cause accidents and injury or death to personnel. (8) Operate forklift on icy surfaces as follows: (a) Turn steering wheel right and left to allow hydraulic fluid in steering system to warm up.  Do this until steering feels normal.  This should be done with the forklift moving slowly to avoid creating flat spots on the tires. (b) Avoid making sudden turns and stops. (c) When slowing or stopping, pump brake pedal to avoid sliding. (d) Begin stopping sooner than normal to avoid sliding. (e) Steer away from ruts and snow banks. (f) Steer forklift straight up and down grades when possible. CAUTION During periods of extreme cold, damage will occur if tires are allowed to freeze to the ground.  If a sheltered area is not available when temperatures are forecast to be below 32°F (0°C), the forklift should be parked in a high, dry area. (9) Park forklift in sheltered area out of wind.  If a sheltered area is not available, park forklift so it does not face into wind. (10) Drain water from fuel/water separator immediately after operating. 2-44
