WARNING - continued

TM 55-4920-438-13&P

When all equipment and materiel is stored on the stationary side of the shelter, the limited floor

space presents a safety hazard to operating personnel. This is most critical during the raising

and lowering of the roof panel. Failure to observe supplemental instructions could result in

serious injury to personnel. Personnel inside the shelter could become trapped between the roof

panel and equipment bolted to the floor.

The two upper lockout pins must be installed at the cable housing prior to raising the shelter

floor from its lower position to its level position. If the lockout pins are not in place, the

counterbalance cable will remain under tension. DO NOT attempt to remove cable if the upper

lockout pins are not installed. Removing cable while under tension could cause serious injury to

personnel.

HIGH VOLTAGE exists in the electrical system of the shop. All electrical inspections, repairs or

replacement will be performed with the power off and only by qualified electricians. Serious

shock hazards exist which could result in injury or even death to personnel.

Methylethylketone (MEK), used to clean replacement inserts, is flammable and toxic. Use only

in well ventilated areas. Breathing vapors can cause headaches and nausea. Repeated contact

with skin can cause irritation. If irritation persists see a doctor. Contact with eyes, wash

immediately with water for 15 minutes and seek medical attention.
