Description

The SPH-5 Maxillofacial Shield (MFS), shown in Figure 1, protects the lower

facial area from ying debris. Latches on the right and left sides of the MFS

attach it to the helmet-mounted strikers.

This booklet includes instructions for installing the strikers on the helmet,

attaching the MFS to the strikers, maintaining the MFS, and replacing end caps.

NOTE: The MFS and mounting jigs are available in sizes Regular and X-Large.

They are used on SPH-5 helmet sizes as follows:

MFS and Mounting Jig Size Helmet Size

Regular Small and Regular

X-Large X-Large and XX-Large

Installation

In the procedure below, you will use the mounting jigs with the MFS to locate

and mark the hole locations for the attachment of the strikers to the helmet.

NOTE: Throughout the procedure, “left side” and “right side” refer to the helmet

as worn.

Tools and Materials Needed

• Drill with 0.185 and 0.040 bits

• Flat-tip screwdriver

• Phillips screwdriver

• Well-sharpened pencil

• White glue

Procedure

1. Prepare the helmet (Figure 2). Do the following:

a. Pressing the connector release button (hidden under shrink tubing),

unplug the microphone cord from the connector.

b. Detach the boom microphone by removing the outer hardware (center

screw or quick-disconnect bracket screws) from the helmet. (The inner

hardware, covered by foam, will remain in place. Attachment style may

vary.) Set the removed parts aside for reinstallation.

c. On one side of the helmet, remove the two lower outer screws that attach

the earcup cross straps to the inside of the helmet. (The rearward inner

post also will be removed. The forward inner post, covered by foam, will

remain in place.) Repeat for the other side.

2. Familiarize yourself with the mounting jigs (Figure 3). Note the following

features:

a. Each mounting jig is marked REG (Regular) or XL. Be sure to select the

correct size for your helmet.

b. Each mounting jig is marked LEFT or RIGHT. Be sure to install each one

on the correct side of the helmet.

c. Each mounting jig is marked FRONT (with an arrow). Be sure that the

arrow points toward the front of the helmet when the jig is installed.

d. Each mounting jig has four slots to allow for variations in cross strap

attachment on SPH-5 helmets. The upper two slots are marked A; the

lower two are marked B. You will attach each jig to the helmet with the

lower cross strap attachment hardware (which you removed in Step 1c)

via the jig slots at the lower helmet cross strap attachment points. Be

sure to use like-marked slots (AA or BB, not AB or BA). Choose the

slots (AA or BB) that will align most closely with the lower cross strap

attachment points.

or RIGHT) for each side of the MFS (left or right as worn). On one side of the

MFS, insert the pin of the latch into the striker feature on the jig and ip the

latch closed. Repeat to attach the other mounting jig to the other side.

4. Lower the inner visor (Figure 5). Push the visor knob outward, and lower

the inner visor to the lowest position. Ensure that the bottom edge of the visor

is level

5. Attach the MFS to the helmet (Figure 6). Do the following:

a. Align the MFS within the lower edge of the visor. Ensure that the lower

edge of the visor is aligned evenly with the upper raised edge of the MFS

b. Position each jig over the ear dome area of the helmet. Ensure that the

striker feature is within the ear dome — not on or past the edge of

the helmet. Determine which set of jig slots (upper or lower) will align

most closely with the lower cross strap attachment holes.

c. On one side of the helmet, use the cross strap screw and post (which you

removed in Step 1c) to attach the jigs to the helmet at the lower rear cross

strap attachment points via the selected jig slot

Repeat for the other side.

Tighten both screws snugly

6. Detach the MFS and install the front screws (Figure 7). With the jigs

attached to the helmet, unlatch the MFS from the jigs. Install both front cross

strap screws snugly. (The inner front posts remain in place behind the foam.)

7. Have the wearer don the helmet (Figure 8). Do the following:

a. Grasp the helmet in the earcup area, and carefully ex the helmet just

enough to clear the head. Be careful not to move the jigs.

b. Place the inside front of the helmet against the forehead, and rotate the

helmet downward onto the head.

c. Press the helmet rmly downward with both hands to ensure that the

helmet is properly seated on the head and the ears are surrounded by

the earcups.

d. Check the distance between the eyebrows and the edge of the helmet

shell. Generally, this distance should be approximately ¾ inch for

optimum eld of view. However, the helmet should be positioned as

normally worn.

8. Have the wearer tighten the nape strap (Figure 9). Adjust the hook-and-

pile closure and tighten the nape strap through the adjustment buckle.

9. Have the wearer fasten the chinstrap (Figure 9). Do the following:

a. If not already done, insert the snap end of the chinstrap through the

D-ring on the right side (as worn) of the retention assembly and fasten

the snap.

b. Feed the other end of the chinstrap through the D-rings on the left side of

the helmet.

c. Split the D-rings, loop the chin strap end back through inner D-ring, and

pull the chin strap through both D-rings.

d. Tighten the chinstrap to the desired tension. Once the desired tension is

achieved, you can fasten and unfasten the chinstrap via the snap.

For helmet stability, always tighten the nape strap and the chinstrap

as snugly as possible when wearing the helmet. Failure to do so may

result in injury.

12. Align the upper raised edge of the MFS within the lower edge of the visor

lens (Figure 12). Ensure that (1) the wearer’s eld of view is not obstructed for

the performance of duties and (2) the MFS does not touch the wearer’s nose.

13. Based on feedback from the wearer, evaluate the t of the MFS. Do the

following:

a. If the t seems good to the wearer, raise the visor, unlatch and remove

the MFS (Figure 12), and proceed to Step 14.

b. If the MFS contacts the nose, loosen the jig screws and adjust the jigs to

raise the MFS slightly (Figure 12). Ensure that the wearer’s eld of view

is not obstructed. Tighten the screws.

c. If the MFS still contacts the nose, adjust the visor upward to next detent

(Figure 12), and adjust the MFS upward. Ensure that the wearer’s eld of

view is not obstructed.

d. If the MFS still contacts the nose, adjust the visor upward one more

detent, and

adjust the MFS upward. E

nsure that the wearer’s eld of view

is not obstructed.

e. If the MFS still contacts the nose, notify your supervisor.
