SPECIFIC SAFETY RULES FOR THE BATTERY & CHARGER
8
WARNING:
Do not let comfort or familiarity with the product replace strict adherence to
product safety rules. Failure to follow the safety instructions may result in serious personal injury.
Despite all the safety precautions, caution must always be exercised when handling batteries. The
following points must be obeyed at all times to ensure safe use. Safe use can only be guaranteed if
undamaged cells are used. Incorrect handling of the battery pack can cause cell damage.
1. TOOL PURPOSE. This charger is designed for recharging WEN 40V Max Lithium Ion batteries (mod-
el numbers 40401 and 40404). Charging any other battery or using a different charger to charge these
batteries could result in fire, injury, or damage. Using the charger for any other purpose for which it is
not designed may result in serious injuries, machine damage and voiding of the warranty.
2. AVOID DANGEROUS ENVIRONMENTS. Do not charge the battery pack in rain, snow or in damp or
wet locations. Do not use the battery pack or charger in the presence of explosive atmospheres (gas-
eous fumes, dust or flammable materials) because sparks may be generated when inserting or remov-
ing the battery pack, which could lead to a fire.
3. CHARGE IN A WELL-VENTILATED AREA. Do not block the charger vents. Keep them clear to allow
for proper ventilation. Do not allow smoking or open flames near a charging battery pack. Vented gases
may explode.
NOTE:
The safe temperature range for charging the battery is 50°F to 104°F. Do not charge the battery
outside in freezing weather; charge it at room temperature.
4. MAINTAIN CHARGER CORD. When unplugging the charger, pull the plug, not the cord, from the
receptacle to reduce the risk of damage to the electrical plug and cord. Never carry the charger by its
cord or yank it by the cord to disconnect it from the receptacle. Keep the cord away from heat, oil and
sharp edges. Make sure the cord will not be stepped on, tripped over or subjected to damage or stress
when the charger is in use. Do not use the charger with a damaged cord or plug. Replace a damaged
charger immediately.
5. DO NOT USE AN EXTENSION CORD UNLESS IT IS ABSOLUTELY NECESSARY. Using the wrong,
damaged or improperly wired extension cord poses a risk of fire and electric shock. If an extension
cord must be used, plug the charger into a properly-wired 16AWG or larger extension cord with the
female plug matching the male plug on the charger. Make sure that the extension cord is in good elec-
trical condition.
6. CHARGER IS RATED FOR 120V, 60Hz AC ONLY. The charger must be plugged into an appropriate
receptacle.
7. USE ONLY RECOMMENDED ATTACHMENTS. Use of an attachment not recommended or sold by
WEN Products may result in risk of fire, electric shock or personal injury.
