CAUTION
Equipment damage. Before backing the launch vehicle in mud, sand or snow, the mud
flaps must be pinned on the stowage hook located on mud flap bracket. If the mud flap is
not pinned, damage may result.
Equipment damage. The tail-lift should be in raised position to avoid damage if sinking
occurs. Suitable ground conditions should always be established prior to bridge build or
retrieval.
Equipment damage. Blowing sand may scratch glass/plastic surfaces. Glass/plastic
surfaces should remain covered as much as possible in these conditions to prevent
scratching.
Equipment damage. Electrical panel doors should always be fastened when not in use.
Keep dust caps on all unused electrical and hydraulic connection points.
Equipment damage. Extreme care should be taken when building or retrieving the bridge
in poor visibility.
NOTE
Driving in mud can degrade launch vehicle braking and speed up brake shoe wear. If
braking degrades while operating in mud, dry brakes by driving launch vehicle
approximately 500ft. (153m) with service brakes frequently applied. This must be done
with brake drums totally out of mud so that drying action can take place. If drying brakes
does not restore adequate braking, notify Unit Maintenance.
12.3.1.1
Leave glass/plastic surfaces covered if not needed for operations. Extra care should
be taken when cleaning glass surfaces to prevent scratching surfaces. Electrical
panel doors should always be fastened when not in use. Keep caps on all unused
electrical and hydraulic connection points.
