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.
BEFORE USE
Check the work area to make sure that it is clear of debris and clutter.
Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.

prescribed precautions.
2. Attaching the side handle (Fig. 7)
(1) Turn the grip of the side handle to loosen it and
push it in until it comes in contact with the housing.
(2) Adjust the side handle to the angle that allows the
