5. Hold the charger firmly and pull out the battery.
   NOTE
   Be sure to pull out the battery from the charger after use, and then keep it.

Regarding electric discharge in case of new batteries, etc
As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2–3 times.

How to make the batteries perform longer.

1. Recharge the batteries before they become completely exhausted. When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.
2. Avoid recharging at high temperatures. A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

MOUNTING AND OPERATION

1. Installing the hose LED and replacing the battery. Remove 2 button cells CR1620 and insert new batteries CR1620 into the cover. Pay attention to the polarity!
2. Adjusting the discharge pressure and speed (by means of the shift knob) and discharge amounts (by means of the dial)

   The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

3. Inspection of terminals (tool and battery)
   Check to make sure that swarf and dust have not collected on the terminals.
   On occasion check prior, during and after operation.

4. Cleaning on the outside
   When the power tool is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline or paint thinner, for they melt plastics.

5. Storage
   Store the power tool and battery in a place in which the temperature is less than 40°C and out of reach of children.

NOTE

• Storing lithium-ion batteries.
• Make sure the lithium-ion batteries have been fully charged before storing them.
• Prolonged storage (3 months or more) of batteries with a low charge may result in performance deterioration, significantly reducing battery usage time or rendering the batteries incapable of holding a charge. However, significantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to five times.
• If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries.

CAUTION : In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed.
