CLEANING
Components of the SPH-5 helmet assembly can be cleaned as follows:
Helmet shell and visor assembly (including visors, housing, tracks, and knobs):
Wipe with clean, soft cloth dampened with mild soap solution; rinse with clean
water and allow to air dry.
Earcups, cords, retention assembly: Wipe with damp cloth; allow to air dry
thoroughly.
TPL cloth cover: Machine wash (gentle cycle) or hand wash with warm water and
soap; allow to air dry.
TPL plastic layers: Hand wash with soap and water; allow to air dry.
REPLACEMENT PROCEDURE 1:
ENERGY-ABSORBING LINER AND TPL
1. Squeezing the sides of the TPL together to clear the earcups as shown in
Figure 13, remove the TPL from the helmet.
2. Remove at least one earcup from the retention assembly as in Replacement
Procedure 3, Steps 1-3 (Page 16).
3. Insert a flat-tip screwdriver or a tongue depressor between the energy-
absorbing liner and the helmet shell in the front and rear and disengage the
hook-and-pile fasteners holding the liner in place.
4. Apply slight pressure to the energy-absorbing liner from the rear and slide it
out through the front of the helmet.
NOTE
Before you install the replacement energy-absorbing liner, ensure that
its hook-fastener tabs are in place in the front and rear.
5. Install the replacement energy-absorbing liner by inserting the rear of the
liner into the front of the helmet and applying slight pressure to position the
liner in the helmet. Ensure that the hook-and-pile fasteners are engaged.
6. Reinstall the earcup(s) as in Replacement Procedure 3, Steps 10 -11
(Page 17).
7. Referring to Figure 13, squeeze the sides of the TPL together to clear the
earcups and attach the TPL to the energy-absorbing liner in the helmet.
Ensure that the label and holes in
the plastic layers (as well as the
double leg of the “Y” seam on the
cloth cover) are positioned toward
the front of the helmet. Center the
TPL in the energy-absorbing liner.
The TPL should protrude
approximately 1/4" past the front
edge of the energy-absorbing
liner.
8. Recheck the helmet fit.
