DANGER
Batteries.
Risk of explosion.
Battery charging produces highly explosive hydrogen gas. Keep the tank assembly open during battery
charging and perform this procedure in well-ventilated areas and away from naked flames.
To reduce the risk of fire, electric shock, or injury, do not leave the machine unattended when it is
plugged in. Before performing any maintenance procedure, disconnect the battery charger cable from the
electrical mains.
Do not smoke while charging the batteries.
The use of non-genuine spare parts, accessories, batteries and chargers can impair the safety of the
appliance. Only use spare parts and accessories from Viper and use batteries and chargers which VIPER
recommend. When using non-certified and not recommended batteries and chargers, VIPER will not
cover the cost of damages (warranty) caused of this.
CAUTION
Battery charger.
Electric shock due to faulty mains connecting lead or charger cable.
Touching a faulty mains connecting lead or charger cable can result in serious or even fatal injuries.
Keep the battery away from sparks, flames and incandescent material. During the normal operation
explosive gases are released.
Before using the battery charger, ensure that frequency and voltage values, indicated on the machine
serial number plate, match the electrical mains voltage.
Do not damage the mains power lead (e.g. by driving over it, pulling or crushing it).
