The operator must be able to remove the backpack battery 
quickly in the event of an emergency. In an emergency, 
open and remove the waist belt and chest strap quickly 
before dropping the battery to the ground.
To ensure a proper fit:
► Put the backpack battery on your back.
► Fasten and adjust the waist belt (2) so that it rests 
comfortably but securely on your hips. 
► Fasten the chest strap (1) and adjust it so that it fits 
comfortably but securely across your chest.
► Adjust the harness straps so that the back padding fits 
snugly and securely against your back.
► Always wear the battery harness over both shoulders.
► Thread the end of the waist belt through the loops (3) 
and (4).
► To remove the harness, open the quick-release fasteners 
on the waist belt and chest strap and loosen the harness 
straps by lifting the sliding adjusters.
To help reduce the risk of injury in the event of an 
emergency, practice quickly opening the fasteners on the 
waist belt and chest strap, loosening the shoulder straps and 
removing the battery.
NOTICE
To avoid damage, ease the battery to the ground when 
practicing. Do not allow the battery to drop to the ground and 
do not throw it.
