Battery
CAUTION
RISK OF EXPLOSION IF BATTERY IS REPLACED
BY AN INCORRECT TYPE.
DISPOSE OF USED BATTERIES ACCORDING
TO THE INSTRUCTIONS.
This device contains a Lithium-Ion (Li-ion) Rechargeable Battery. This battery may be forbidden
aboard passenger aircraft and is not to be transported via air with a charge greater than 30%
capacity per ICAO Packing Instructions 965.
Damage to a Li-ion battery may result in a flammability hazard.
Only batteries manufactured by Guardhat are safe to use with this model.
Only a Guardhat charger should be used to charge the batteries. Charging must take place only
in an environmentally safe location because any intrinsic safety or ingress protection ratings
held by the hard hat assembly are not applicable to a battery with exposed terminals.
Fit
The hat must be worn snugly to prevent slipping off. Always adjust the suspension to fit the
user before wearing into a work zone. (see Wearing the Hard Hat, page 13)
