BATTERY & CHARGER SAFETY WARNINGS

ABOUT THE BATTERY

1. The battery pack has to be charged completely before you use the tool for the first time.
2. For optimum battery performance, avoid low discharge cycles by charging the battery pack frequently.
3. Lithium-ion batteries are subject to a natural aging process. The battery pack must be replaced at the latest when 

its capacity falls to just 80% of its capacity when new. Weakened cells in an aged battery pack are no longer capable 

of meeting the high power requirements needed for the proper operation of your tool, and therefore pose a safety 

risk.
4. Do not throw battery packs into an open fire as this poses a risk of explosion. Do not ignite the battery pack or 

expose it to fire.
5. Do not exhaustively discharge batteries. Exhaustive discharge will damage the battery cells. The most common 

cause of exhaustive discharge is lengthy storage or non-use of partially discharged batteries. Stop working as soon 

as the performance of the battery falls noticeably or the electronic protection system triggers. Place the battery pack 

in storage only after it has been fully charged.
6. Protect batteries and the tool from overloads. Overloads will quickly result in overheating and cell damage inside 

the battery housing even if this overheating is not apparent externally.
7. Avoid damage and shocks. Immediately replace batteries that have been dropped from a height of more than 

one meter or those that have been exposed to violent shocks, even if the housing of the battery pack appears to be 

undamaged. The battery cells inside the battery may have suffered serious damage. In such instances, please read 

the waste disposal information for proper battery disposal.
8. If the battery pack suffers overloading and overheating, the integrated protective cutoff will switch off the equip-

ment for safety reasons.
9. Use only original battery packs. The use of other batteries poses a fire risk and may result in injuries or an explo-

sion.

ABOUT THE CHARGER

Protect battery charger and cord from damage. Keep the charger and its cord away from heat, oil and sharp edges.
Electrical plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with ground-

ed appliances. Unmodified plugs and matching outlets will reduce the risk of electric shock.
Keep the battery charger, battery pack(s), and the cordless tool out of the reach of children.
Do not use the supplied battery charger to charge other cordless tools.
During periods of heavy use, the battery pack will become warm. Allow the battery pack to cool to room temperature 

before inserting it into the charger to recharge.
Do not overcharge batteries. Do not exceed the maximum charging times. These charging times only apply to dis-

charged batteries. Frequent insertion of a charged or partially charged battery pack will result in overcharging and 

cell damage. Do not leave battery in the charger for days on end.
Never use or charge a battery if you suspect that it has been more than 12 months since last time they were charged. 

There is a high probability that battery pack has already suffered dangerous damage (exhaustive discharge).
Do not use battery that have been exposed to heat during the charging process, as the battery cells may have suf-

fered dangerous damage.
Do not use battery that have suffered curvature or deformation during the charging process or those that exhibit 

other atypical symptoms (gassing, hissing, cracking, etc.)
