If the input rating of a battery charger is given in
watts rather than in amperes, the corresponding
ampere rating is to be determined by dividing the
wattage rating by the voltage rating-for example:
1,200 watts/120volt=10 Amperes
9. Do not operate battery charger with damaged
cord or plug，should replace them immediately.
10. Do not operate battery charger if it has received
a sharp blow, been dropped, or otherwise damaged
in any way; take it to a qualified serviceman.
11. Do not disassemble battery charger; take it to a
qualified serviceman when service or repair is
required.
Incorrect reassembly may result in a risk of
electric shock or fire.
12. To reduce risk of electric shock, unplug charger
from receptacle before attempting any maintenance
or cleaning. Removing the battery will not reduce
this risk.
13. Please read this Manual before using the battery
charger.

nailer and fuel cell indoor 30 minutes.
This Nailer is equipped with a FULL SEQUENTIAL
ACTUATION MECHANISM.
Explanation of FULL SEQUENTIAL ACTUATION
MECHANISM nailing operation:
First, press the push lever against the workpiece;
Next, press downward nailer;
Then, pull the trigger to drive a nail.
The machine employs a preventive mechanism
for unloaded operation.
The machine enters a state where the push lever
cannot be pushed up in place. This takes place
when the magazine is not loaded with nails or when
the remaining number of nails becomes less than 2
or 3.
CAUTION
Use caution not to press the nailer mouth tip
against to the workpiece when the nailer mouth
lever cannot be pushed up in place.
METHODS OF OPERATION
This Nailer is equipped with the nailer mouth and
does not operate unless the nailer mouth is
depressed upward top dead center position.
It is intermittent operation (Trigger fire) only.
(1) Position the nail outlet on the workpiece with finger
off the trigger.
(2) Depress the nailer mouth firmly until it is
completely depressed.
(3) Pull and squeeze the trigger to drive a nail.
(4) Remove finger from the trigger.
To continue nailing in a separate location, move
the nailer along the workpiece, repeating above
steps (1) -(4) as required.

NOTE: The battery charging time becomes longer
when a temperature is low or the voltage of
the power source is too low.
When the green pilot lamp does not light on
even if more than three hours has passed
after start of the charging, stop the charging
and contact your TOUA AUTHORIZED
SERVICE CENTER.
5. Disconnect battery charger from the power plug.
CAUTION
Do not pull the plug out of the receptacle by
pulling on the cord.
Make sure to grasp adapter plug when removing
from receptacle to avoid damaging adapter.
6. Remove the battery from the battery charger.
Supporting the charger base with hand, pull out
the battery from the charger base.
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 battery perform longer
1. Do not recharge the batteries after they become
completely exhausted.
When you find the power pilot lamp change from
green to red on ther nailer handle, should stop to
operate the nailer and recharge its battery. If you
continue to use the nailer 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
■ When the battery charger has been continuously
used, the battery charger will be heated, thus
constituting the cause of the failures. Once the
charging has been completed, give 15 minutes
rest until the next charging.
■ If the battery is recharged when it is warm due
to battery use or exposure to sunlight, the pilot
lamp may not light. The battery will not be
recharged. In such a case, let the battery cool
before charging.
■ If the battery charger does not work while the
battery is mounted correctly, it is probable that
the battery or charger is malfunctioning. Take
it to your TOUA authorized Service Center.

NOTE: The battery charging time becomes longer
when a temperature is low or the voltage of
the power source is too low.
When the green pilot lamp does not light on
even if more than three hours has passed
after start of the charging, stop the charging
and contact your TOUA AUTHORIZED
SERVICE CENTER.
5. Disconnect battery charger from the power plug.
CAUTION
Do not pull the plug out of the receptacle by
pulling on the cord.
Make sure to grasp adapter plug when removing
from receptacle to avoid damaging adapter.
6. Remove the battery from the battery charger.
Supporting the charger base with hand, pull out
the battery from the charger base.
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 battery perform longer
1. Do not recharge the batteries after they become
completely exhausted.
When you find the power pilot lamp change from
green to red on ther nailer handle, should stop to
operate the nailer and recharge its battery. If you
continue to use the nailer 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
■ When the battery charger has been continuously
used, the battery charger will be heated, thus
constituting the cause of the failures. Once the
charging has been completed, give 15 minutes
rest until the next charging.
■ If the battery is recharged when it is warm due
to battery use or exposure to sunlight, the pilot
lamp may not light. The battery will not be
recharged. In such a case, let the battery cool
before charging.
■ If the battery charger does not work while the

against to the workpiece when the nailer mouth
lever cannot be pushed up in place.
METHODS OF OPERATION
This Nailer is equipped with the nailer mouth and
does not operate unless the nailer mouth is
depressed upward top dead center position.
It is intermittent operation (Trigger fire) only.
(1) Position the nail outlet on the workpiece with finger
off the trigger.
(2) Depress the nailer mouth firmly until it is
completely depressed.
(3) Pull and squeeze the trigger to drive a nail.
(4) Remove finger from the trigger.
To continue nailing in a separate location, move
the nailer along the workpiece, repeating above
steps (1) -(4) as required.

1. Daily cleaning
Must regularly to clean nailer, remove the internal
accumulation of smeary, carbon and dust, and to
ensure the normal operate, extend nailer working
life. Please use TOUA designated cleaner
(504.6.04.001.01).
Follow the attachment Gas Concrete Nailer
Cleaning Guide-a steps and methods to clean
the nailer.
TOUA nailer cleaning intervals depends on the
nailer operating environment and the firing quantity
per week of nails. If using at the dirty environmental
and firing large quantity per week, nailer cleaning
intervals will be shorter.
Below is the cleaning time intervals form for you
reference. If you according to the cleaning time
intervals form to clean the nailer find the nailer is
extremely dirty, the cleaning time intervals should
be shorten, conversely, if find ther nailer is very
clean, extend cleaning time intervals.
