HOSS - Owner's Manual 25
Some chargers have a small cooling fan located inside the charger which is thermostatically con-
trolled and may come on when internal temperatures rise beyond design limits. This may or may not
operate at regular intervals. Do not rely on it’s operation as an indication of charger output.
Important Safety Instructions:
+++ Because you will be connecting and disconnecting AC voltage to the wheelchair,
DO NOT do so in the presence of moisture (i.e. rain, puddled water, snow, etc.). Electrical shock
hazard could be present. Observe caution and safety warnings.
a.) Observe the caution on lead-acid batteries being charged. Batteries can generate explosive gas-
ses during operation. It is for this reason that you must read and follow these safety precautions;
b.) To reduce risk of battery explosion;
i. never smoke or allow open flame or sparks around a charging battery;
ii. never charge a frozen battery;
iii. use charger for charging lead acid-type or AGM batteries only; it is not intended to charge dry cell
batteries, or act as a power source for low voltage circuits. Either of these conditions could harm the
charger or cause dangerous conditions to exist. This charger is recommended for use with deep cycle-
type batteries.
c.) Study all information supplied with batteries. Study battery precautions such as removing or not
removing caps during charging, as well as the recommended rate of charge.
d.) The user is instructed to NOT use the charger with a battery configuration not matching the output
voltage rating of the charger.
e.) Do not operate the charger in closed area or restrict ventilation around the charger in any way.
f.) Do not disconnect the DC portion of the charger circuit while the AC cord is still connected to
the electrical outlet.
Basic Safety Instructions:
1. Do not expose the charger to rain, snow or other moisture sources (i.e., sprinkler, car wash, etc.). When
storing wheelchair, keep inside a building.
2. Use of the charger in a manner not recommended by the manufacturer may result in the risk of fire,
electrical shock or personal injury.
3. To reduce the possibility of damage to the AC cord or the connector, disconnect the AC line cord by
grasping the plug and not the cord, when disconnecting from either the wheelchair or the wall receptacle.
4. Locate cord so that it will not be stepped on, tripped over or subjected to the possibility of damage.
5. An extension cord is not recommended for use with this equipment. Use of an improperly
rated extension cord could result in risk of fire or electrical shock. Should it be required to use
an extension cord, make certain that it is of 3-wire construction and has a wire size of 16-gauge,
and the cord must be in good electrical condition.
6. Do not operate this charger with damaged AC cord or receptacle. If they are damaged, replace
them immediately.
