carefully set it aside to prevent damage to the flat joint and flange gasket.
To avoid explosion, do not damage the flat joint surfaces. Do not use hammers or
prying tools to open covers. Do not handle covers roughly, or place them on
surfaces that might damage or scratch the flat joint surfaces.

plate and loosen the retaining screw of one (1) of the battery stop brackets. Remove
battery. Retain battery insulating sheet for use with replacement battery.
To avoid potential explosion, do not short circuit the battery or connector
terminals.
6. Cover replacement battery with insulating sheet and reinstall battery using hold-down
bracket and four (4) screws previously removed. Re-tighten battery stop bracket
screw. Reconnect black battery conductor and red conductor using wire nuts.
To avoid exposing battery terminals, insulating sheet must completely cover the
battery.
To avoid explosion, clean both flat joint surfaces of body and cover before
closing. Dirt or foreign material must not accumulate on flat joint surfaces.
Surfaces must seat fully against each other to provide a proper explosionproof
seal.

cell with conductive materials such as rings, bracelets, and keys. The cell or
conductor may overheat and cause burns.
2. Do not dispose of the cell/battery in open flame; cells may burst.
3. Do not open or mutilate cell/battery. Opened cells may release corrosive
electrolytes which may have harmful effects on the skin and eyes and may
be toxic if ingested.
