5. Hold the charger fi rmly 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 the 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.

CAUTION

• If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the charge indicator lamp of the charger lights for 0.3 seconds, does not light for 0.3 seconds (off for 0.3 seconds). In such a case, first let the battery cool, then start charging.
• When the charge indicator lamp fl ickers (at 0.2-second intervals), check for and take out any foreign objects in the charger’s battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.

MOUNTING AND OPERATION

*1 Adjusting operating speed
This can be performed even while working. Adjust the speed together with the amount that the switch is pulled.

CAUTION
If the diameter of the cross-section of the nozzle is 3 mm or smaller, or if there is an attempt to abruptly dispense at high speed while under low- temperature conditions, the sealing material may leak out on the piston side.
Begin at low speed, and gradually increase speed to suit the hardness of the sealing material.

2 Switch operation
Immediately after the switch is released, the piston retracts slightly to prevent sealing material remaining at the end of the nozzle from dripping.
3 How to use the Hook
The hook can be used to hang up the unit temporarily during operations.

CAUTION
The hook should never be used to hang the unit on your person.
When using the hook, check to make sure that the main unit will not slip and fall, or become unstable by the wind, etc.
Never hang the unit from your belt or trousers as this could cause accidents.

*4 Exchanging the rack (push-out rod)
NOTE
Install the rack (push-out rod) with its teeth facing downward.
The rack (push-out rod) for 300 ml can also be used for 400 ml.
*5* Types of pistons
There are 3 types of pistons for diff erent sealing materials.
a: Cartridges
b: Sausages
c: Buckets
Choose a holder and piston according to the sealing material.
6 Exchanging the piston
The piston can be detached from the rack (push-out rod) by twisting the piston counter-clockwise. To attach it, twist it in the opposite direction to screw it in. Exchanging it does not require any tools.
7 Using cartridges, sausages, and buckets
CAUTION
Do not make the diameter of the cut cross-section of the nozzle 3 mm or smaller. Doing so may cause leakage of sealing material on the piston side or damage to the holder or holder cap.
8 Temporarily setting down the tool while working
NOTE*
The tool can be temporarily set down upside-down while working. When doing so, set it down on a stable surface.
9 Removing hardened sealing material
