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.

PREPARATION PRIOR TO OPERATION

CAUTIONS
No flammable gas, liquid or other flammable objects
at worksite.
Use outside or well–ventilated areas.
Do not inhale.
Keep the tool, fuel cell and battery away from sunshine
and from temperature exceeding 50°C.
Keep away from ignition sources. No smoking.
Clear the area of children or unauthorized personnel.
Do not store the tool, fuel cell and battery in a cold
weather environment. Keep the tool, fuel cell and
battery in a warm area until beginning the work.
If the tool, fuel cell and battery are already cold, bring
it in a warm area and allow the tool to warm up before
use.
Observe temperature limit of max. 50°C .
Do not expose to an open flame and sparks!
This tool may not drive completely below when;
– at low temperature fuel cell loose the required
propellant force,
– at high temperature fuel cell overdose.
Do not use the tool in the rain or where excessive
moisture is present.
This tool is not recommended for use at altitudes
above 1,500 m, or in temperature below 0°C.

1. Fuel cell

To attach the metering valve to a fuel cell:
(1) Separate the metering valve and the cap from the gas
cartridge (See Fig. 3 (1)).
(2) Press forward (stem side) and downward on the front
side of the metering valve (See Fig. 3 (2)).
(3) Press downward on the rear of the metering valve
until it seals (See Fig. 3 (3)).
Check the metering valve:
Press the metering valve stem on fuel cell two or three
times against a stationary object and release.
If gas is not dispersed, fuel cell is empty. Replace it.
Observe Safety Regulations
CAUTION
If the gas leaks from the metering valve or the gas
cartridge after attached the metering valve, replace
with the new metering valve.
Do not attempt to reuse the metering valve.
Replace with the new metering valve.
2. Battery
You must charge the battery before use.
The charging method of battery is shown in page 46.

3. Check on safety
CAUTIONS
Unauthorized persons (including children) must be
kept away from the equipment.
Wear eye protector.
Check the retaining screws which fix the top cover,
etc. for tightness.
Check the tool for defective or rusty parts.
Check whether or not the push lever works correctly
without nails, fuel cell and battery. Also check whether
or not any dirt has adhered to the moving parts of the
push lever.
Recheck on operational safety.

BEFORE USE

1. Insert battery into the tool (See Fig. 4)
Do not operate the push lever or trigger while
installing the battery.
Make sure the battery indicator light is flashing GREEN
(See Fig. 5).
If the battery indicator light is flashing RED, the battery
doesn't have enough power and it needs to be
charged.
BATTERY INDICATOR LIGHT
– Flashing GREEN: Enough power remaining (The
– Flashing RED: Insufficient power remaining (The
light turns steady during operation).
– OFF: The battery is extremely empty. Charge the
battery.
Power saving mode
If the tool has not been used for about an one hour
with the battery still installed, Power saving mode
turns on to minimize unnecessary consumption of
battery power. Power saving mode is also activated
when the battery power is extremely low or there's
an abnormality in the machine so please pay attention
to the battery indicator light after deactivating Power
saving mode (by removing the battery and reinstall
it).
2. Insert fuel cell into the tool
(1) Pulling the latch and open the cell cover (See Fig. 6).
(2) Insert the fuel cell into the tool (See Fig. 7).
(3) Insert the stem of fuel cell into the hole of adaptor
(See Fig. 8).
(4) Close the cell cover.
3. Load nails
(1) Insert nail strip into rear of magazine (See Fig. 9).
(2) Slide the nail strip forward in the magazine (See Fig. 10).
(3) Pull the nail feeder (B) back to engage the feeder knob
to the nail strip (See Fig. 11).
NOTE
Use nail strip of more than 10 nails.
The Nailer is now ready to operate.
Removing the nails:
1 Pull the feeder knob backward (See Fig. 12).
2 Return the feeder knob forward quietly while pushing
the nail feeder (B).
3 Pull out nails from the back of the magazine (See Fig.
13).
