For grips with rechargeable system, a 2.5 V lithium-ion battery is used (code 31587), which is included in the
set.

that the poles point in the right direction as indicated.

• Do not use the equipment in case it is damaged. Apply to your retailer.
• Periodically check the battery conditions, making sure that no sign of corrosion or oxidation is pres-
ent. In case of necessity replace them with new alkaline ones.
• Carefully handle the batteries as the liquids they contain can irritate skin and eyes.
• Before being used, thoroughly check the product. The same operation shall be carried out after
cleaning.
