To keep moisture from building up inside air reservoir (5) and freezing, air should be drained from air
reservoir after each operation. Turn air reservoir valve (6) and drain air from air reservoir, close valve.
Park in shelter when possible. Place planks or brush under FRS so it will not freeze in
place.
Keep fuel tank as full as possible during cold operations. Water forms in empty fuel tank
as it cools. Water in fuel system could freeze and block fuel system.
(5)
Place the FRS on high, dry ground if possible. If high, dry ground is not available, spread out planks or
brush to make raised and dry area so the FRS will not freeze in snow, water, ice, or mud.
(6)
Place the FRS on level ground so body does not twist.
(7)
Keep FRS free of snow and ice. Use broom or applicable material to remove snow and ice from shelter,
as soon as possible.
