Description

WARNING – READ OPERATOR’S MANUAL

Read, understand, and follow all instructions in the manual(s) 
before attempting to assemble and operate.

WARNING – DOUBLE INSULATION

 

The charger is double insulated; therefore no ground wire is 
required. Always check that the mains voltage corresponds to 
the voltage on the rating plate. Never attempt to replace the 
charger unit with a regular mains plug.

WARNING – INDOOR USE ONLY

This charger is intended for indoor use only.

WARNING – ELECTRONIC ITEMS DISPOSAL

Electrical and electronic items should not be disposed of with 
other household waste, but should be recycled.

SAVE ALL WARNINGS AND INSTRUCTIONS  

FOR FUTURE REFERENCE

SAVE THESE INSTRUCTIONS:

 This manual contains important safety and operating instructions for 

battery chargers.
Charger is engaged when charger connection is securely connected to the charger port on the machine 

and the charger connection latch is in the closed position.

Important Safety Instructions for All Battery Chargers

 WARNING

Read all safety warnings, instructions, and cautionary markings for the battery pack, charger, and 

machine. Failure to follow the warnings and instructions may result in electric shock, fire, and/or 

serious injury.

• 

This appliance is not intended for use by persons (including children) with reduced physical, 

sensory, or mental capabilities, or lack of experience and knowledge, unless they have been 

given supervision or instruction concerning use of the appliance by a person responsible for 

their safety.

• 

Children should be supervised to ensure that they DO NOT play with the appliance.

• 

Cleaning and user maintenance shall not be made by children without supervision.

• 

If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or 

similarly qualified persons in order to avoid a hazard.

• 

DO NOT attempt to recharge non-rechargeable batteries.

• 

DO NOT attempt to charge the battery pack with any chargers other than the ones 

in this manual. 

The charger and battery pack are specifically designed to work together.

• 

These chargers are not intended for any uses other than charging original 

manufacturer rechargeable batteries. 

Any other uses may result in risk of fire, electric 

shock or electrocution.

• 

DO NOT expose the charger to rain or snow.

• 

Pull by the plug rather than the cord when disconnecting the charger. 

This will 

reduce the risk of damage to the electric plug and cord.

• 

Make sure that the cord is located so that it will not be stepped on, tripped over or 

otherwise subjected to damage or stress.

• 

DO NOT use an extension cord unless it is absolutely necessary. 

Use of improper 

extension cord could result in risk of fire, electric shock or electrocution.

• 

An extension cord must have adequate wire size (mm2) for safety. 

The larger the size 

of the wire, the greater the capacity of the cable. An undersized cord will cause a drop in line 

voltage resulting in loss of power and overheating. When using more than one extension to 

make up the total length, be sure each individual extension contains at least the minimum 

wire size. The following table shows the correct size to use depending on cord length and 

nameplate ampere rating. If in doubt, use the next larger cord.

Not Recommended

• 

DO NOT place any object on top of the charger or place the charger on a soft surface 

that might block the ventilation slots and result in excessive internal heat. 

Place the 

charger in a position away from any heat source. The charger is ventilated through slots on the 

side of the housing.

• 

DO NOT operate the charger with a damaged cord or plug.

• 

DO NOT operate the charger if it has received a sharp blow, been dropped or 

otherwise damaged in any way. 

Take it to an authorized service center.

• 

DO NOT disassemble the charger; take it to an authorized service center when 

service or repair is required. 

Incorrect reassembly may result in a risk of electric shock, 

electrocution or fire.

• 

Disconnect the charger from the outlet before attempting any cleaning. This will 

reduce the risk of electric shock. 

Removing the battery pack will not reduce this risk.
