(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3
.
Table 3
Charging time (At 20°C)
NOTE:
The charging time may vary according to temperature
and power source voltage.
4. Disconnect the charger’s power cord from the
receptacle.
5. Hold the charger firmly and pull out the battery.
NOTE:
After operation, pull out batteries from the charger
first, and then keep the batteries properly.
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.
CAUTION:
䡬
When the battery charger has been continuosly 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.
䡬
If the battery is recharged when it is warm due to battery
use or exposure to sunlight, the pilot lamp map light in
green.
The battery will not be recharged. In such a case, let the
battery cool before charging.
䡬
When the pilot lamp flickers in red (at 0.2-second intervals),
check for and take out any foreign objects in the charger’s
battery installation hole. If there are no foreign objects, it is
probable that the battery or charger is malfunctioning.
Take it to your authorized Service Center.
PRIOR TO OPERATION
1. Setting up and checking the work environment
Check if the work environment is suitable by following
the precautions.
2. Preparing the screws
Select screws appropriate to the application.
3. Bit checking and replacement
A No. 2 Plus bit is installed on this machine as a
standard accessory. Always inspect the bit to make
sure it is not damaged. Using worn bits can cause
screw-in malfunctions. Inspect the bit before work
and quickly replace it with a new one when it starts
to wear out. When the bit must be replaced due
to bit damage or any other reason, replace it
according to the instructions in Bit installation and
removal.
SWITCH ACTION (FIG. 4)
CAUTION
Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the “OFF” position when
released.
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop.
Reversing switch action (Fig. 5)
This tool has a reversing switch to change the
direction of rotation. Depress the reversing switch
lever from the
R
side for clockwise rotation or
from the
L
side for counterclockwise rotation.
When the reversing switch lever is in the neutral
position, the switch trigger cannot be pulled.
Pulling the switch trigger rotates the motor, but the
bit does not rotate. The bit rotates and tightens a
screw when the tip of the bit is pressed against
the groove on the screw head.
CAUTION
䡬
Always check the direction of rotation before
operation.
䡬
Use the reversing switch only after the tool comes to
a complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
䡬
When not operating the tool, always set the reversing
switch lever to the neutral position.
ADJUSTING THE SCREW LENGTH AND
SCREW-IN DEPTH
1. Set the screw length (Fig. 6)
Set the screw length on this unit by sliding the guide
block.
(1) Slide the guide block while holding down the lever
and align the arrow on the guide block with the
number on the stopper to match the screw length.
(2) Find the screw length and screw guide position by
checking the table below.
