• 

Store your battery pack and charger in a cool, dry 

place – Do not store the battery pack or charger where 

temperatures may exceed 104ºF (40ºC), such as in direct 

sunlight or inside a vehicle or metal building during  

the summer.

Information about the battery

1.  The battery pack supplied with your cordless pole chain 

saw is only partially charged. 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.  Store the battery pack in a cool place, ideally at 59°F 

(15°C) and charged to at least 40%.

4.  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 cordless pole 

chain saw, and therefore pose a safety risk.

5. 

Do not throw battery packs into an open fire as this poses 

a risk of explosion.

6. 

Do not ignite the battery pack or expose it to fire. Do not 

expose a battery pack or appliance to fire or excessive 

temperature. Exposure to fire or temperature above 130°C 

may cause explosion. The temperature of 130°C can be 

replaced by the temperature of 265°F.

7.  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 long-term storage only after it has been 

fully charged.

8.  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.

9.  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.

10. 

If the battery pack suffers overloading and overheating, 

the integrated protective cutoff will switch off the 

equipment for safety reasons.

IMPORTANT! 

Do not press the ON/OFF switch any more 

if the protective cut-off has been activated. This may 

damage the battery pack.

11. Use only original battery packs. The use of other batteries 

poses a fire risk and may result in injuries or an explosion.

Information about the charger and the 

charging process

1.  Please check the data marked on the rating plate of the 

battery charger. Be sure to connect the battery charger 

to a power supply with the voltage marked on the rating 

plate. Never connect it to a different mains voltage.

2.  Protect the battery charger and its cord from damage. 

Keep the charger and its cord away from heat, oil and 

sharp edges. Have damaged cords repaired without delay 

by a qualified technician at an authorized Snow Joe

3.  Electrical plugs must match the outlet. Never modify 

the plug in any way. Do not use any adapter plugs with 

grounded appliances. Unmodified plugs and matching 

outlets will reduce the risk of electric shock.

4.  Keep the battery charger, battery pack(s) and the cordless 

tool out of the reach of children.

5.  Do not use the supplied battery charger to charge other 

cordless tools.

6.  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.

7.  Do not overcharge batteries. Do not exceed the maximum 

charging times. These charging times only apply to 

discharged batteries. Frequent insertion of a charged or 

partially charged battery pack will result in overcharging 

and cell damage. Do not leave batteries in the charger for 

days on end.

8.  Never use or charge batteries if you suspect that it has 

been more than 12 months since the last time they were 

charged. There is a high probability that the battery pack 

has already suffered dangerous damage (exhaustive 

discharge).

9.  Charging batteries at a temperature below 50°F (10°C) will 

cause chemical damage to the cells and may cause a fire.

10. Do not use batteries that have been exposed to heat 

during the charging process, as the battery cells may have 

suffered dangerous damage. 

11. 

Do not use batteries that have suffered curvature or 

deformation during the charging process or those that 

exhibit other atypical symptoms (gassing, hissing, 

cracking, etc.)

12. Never fully discharge the battery pack (maximum 

recommended depth of discharge is 80%). A complete 

discharge of the battery pack will lead to premature aging 

of the battery cells.

13. Follow all charging instructions and do not charge the 

battery pack or appliance outside of the temperature 

range specified in the instructions. Charging improperly 

or at temperatures outside of the specified range may 

damage the battery and increase the risk of fire.

14. 

Have servicing performed by a qualified repair person 

using only identical replacement parts. This will ensure 

that the safety of the product is maintained.
