Cleaning

Clean off mud or other foreign matter with brush, damp or dry cloth, or scrub the exceedingly
dirty areas with limited amounts of water that will not saturate the insulation; then rinse off and dry.

CAUTION

Do not starch, bleach, or dry clean. Discoloration and degradation of infrared protection
capacity of the material will result.

Field Laundry

The sleeping bags will be laundered using formula II of FM 42-414. Bivy Cover will be laundered using
formula Vlll of FM 42-414.

CAUTION

Do not starch, bleach, or dry clean. Discoloration and degradation of infrared protection
capacity of the material will result.

Machine/Hand Laundering

Sleeping Bags, may be machine laundered using the delicate/ gentle fabric cycle or by hand, using cold
water (Up to 85° F/30°C) and cold water laundry detergent. Wash and rinse the bivy cover in a standard
commercial washing machine at less than 100 F using low cycle. Rinse thoroughly in clean warm water.

CAUTION

Drying temperature for sleeping bag must not exceed 130°F (54°C). Degradation of the
component materials will result.

Do not press. Degradation of the component materials will result.

Drying

Tumble dry the sleeping bags at lowest fabric cycle delicate/gentle. Do not exceed 90°F (32°C) at no
more than 2/3 capacity. Remove immediately at end of drying. Avoid over drying. To drip dry, remove
from water and place on rustproof hanger. Tumble dry the bivy cover at low temperature (100° F/38°C)
and remove immediately from dryer. Avoid over drying. To drip dry, remove from water and place on
rustproof hanger.

MODULAR SLEEP SYSTEM REPAIR

Filling Material Repair

The filling material (batting) of the MSBS sleeping bags is so constructed that it will not separate or fall
out unless tears or holes are large. If the bag lining cannot be patched as described below, the item
should be classified code H.

Iron-on Patches

1. Cut patches to the desired size and shape such that the patch, when applied, will extend

approximately 3/4 inch (1.9 CM) in all directions from the tear or damaged area. Patches will have
rounded corners.

2. With the sleeping bag unzipped, place the area to be patched on a wooden or other nonmetallic

surface not affected by heating or ironing.

3. Smooth out by hand. Remove any feathers on the area to be patched.

4. Pre-warm the area to be patched by pressing with a household electric dry or steam iron. Use a dry

iron set at “cotton” or high as possible without scorching the fabric for about 5 seconds.

5. Immediately cover with patching material previously cut in the desired size and shape.

6. Hold the iron on the patch for about 8 seconds. Use only a slight rotating or reciprocal motion of the

iron.

7. Allow to cool about 5 seconds or long enough so that the patch will not drift off when the patched bag

is removed from the table. Adjust the heating, pressing, and cooling times as required for the specific
iron being used.

8. Check the quantity of the adhesive bond periodically as follows and adjust heating times and

temperatures of the iron accordingly.

NOTE

A bonded patch which has a lifted edge or which is suspected or found by the check test
to be weakly bonded may be re-ironed, e.g., replacement is not required.

A small amount of patch adhesive strike-through is not objectionable for sleeping bag
repair, provided the patch meets the check test.

9. Test a patch that has cooled for about 5 minutes by picking with the fingers at an edge of the patch

until a tab 1/4-to 1/2-inch (0.635 to 1.27 CM) long is formed. Pull hard on the tab with fingers. A well-
bonded tab will be difficult to peel off. This will indicate that iron adjustment and time heating the
patch is adequate.

10. Replace the test patch with a new patch or re-iron the old patch.

Re-stitching

CAUTION

Re-stitching of the bivy cover can only be done at the edge binding. Do not perform re-
stitching on any seam where you cannot see both sides of the existing stitching.

Re-stitch using sewing machine, thread and stitch listed in Table 1. Re-stitch directly over the original
stitch pattern as closely as possible. Lock each row of stitching by backstitching at least ¾ inch (1 .905
cm). Maintain thread tension to prevent loose stitching.

from end.

7. If necessary, run drawcords through appropriate spring locks.

SKI SERVICE

Cleaning

Thoroughly clean each item, removing mud, dirt or other foreign matter, using brush, cloth, steel wool or
other type of suitable cleaners. To clean molded leather, wipe with a moist cloth; apply saddle soap
working lather well into leather, rinse with sponge and clean water, and allow to air dry. Apply in well-
ventilated area and thoroughly wash hands with cool water and soap after using.

Waxing Skis

Keep the running surfaces of skis well waxed at all times. This is necessary not only to help sliding and
climbing but also for waterproofing to avoid warping. Use appropriate wax, depending on type of snow on
which skis are to be used. For waxing, refer to FM 31-70.

END OF TASK

SKI REPAIR

The repair of skis (Type l), snowshoes, and accessories under normal conditions is usually of an
emergency type consisting of tightening and/or replacing screws, steel edge, and bindings. To facilitate
repair, the following items are necessary: repair kit, ski, replacement components, and bindings.

Ski Poles

Keep the steel point of ski poles sharp by filing. Turn in damaged poles for replacement.

END OF TASK

Binding Repair

1.  Use a tape to measure the ski in a straight line from the tail of the ski to the tip (Figure 1).

2. Divide the total distance in half (which gives you your center or mid-point); half of a 82 ¾-inch ski, for

example, would be 41 3/8 inches. Always measure from the tail of the ski.

3. Mount the binding so that the swivel point of the toe piece is on the mid-point of the ski.
