(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 5.
Table 5 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 charging, 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
If the battery has been heated right after operation
(or due to sunlight, etc.), the charger’s pilot lamp may
not light in red. In such a case, first let the battery
cool, then start charging.
䡬
When the pilot lamp flikers in red quickly (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.
䡬
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged with
UC14YFA is taken out, wait for a minimum of 3
seconds before reinserting it to continue charging. If
the battery is reinserted within 3 seconds, the battery
may not be properly charged.
PRIOR TO OPERATION
1. Preparing and checking the work environment
Make sure that the work site meets all the conditions
laid forth in the precautions.
2. Checking the battery
Make sure that the battery is installed firmly. If it is at
all loose it could come off and cause an accident.
3. Selecting the socket matched to the bolt
Be sure to use a socket which is matched to the bolt
to be tightened. Using an improper socket will not
only result in insufficient tightening but also in
damage to the socket or nut.
A worn or deformed hex. or square-holed socket will
not give an adequate tightness for fitting to the nut or
anvil, consequently resulting in loss of tightening
torque.
Pay attention to wear of socket hole, and replace
before further wear has developed.
Finally, install the socket prescribed in Item 4. The
section on “Optional Accessories” details the
relationship between bolt sizes and sockets. Sockets
are named according to the dihedral width of the
hexagonal hole.
4. Installing a socket
Select the socket to be used.
䢇
Pin, O-ring type (Fig. 5 and 6)
(1) Align the hole in the socket with the hole in the anvil
and insert the anvil into the socket.
(2) Insert the pin into the socket.
(3) Attach the ring to the groove on the socket.
䢇
Plunger type (Fig. 7)
Align the plunger located in the square part of the
anvil with the hole in the hex. socket. Then push the
plunger, and mount the hex. socket on the anvil. Check
that the plunger is fully engaged in the hole. When
removing the socket, reverse the sequence.
HOW TO USE
CAUTION
䡬
When using the hook, pay sufficient attention so that
the main equipment does not fall. If the tool falls, there
is a risk of accident.
䡬
Do not attach the tip tool except phillips bit to the tool
main unit when carrying the tool main unit with the
hook suspended from a waist belt.
Injury may result if you carry the equipment
suspended from the waist belt with sharp tipped
components such as drill bit attached.
1. Using the hook
The hook can be installed on the right or left side and
the angle can be adjusted in 5 steps between 0
°
and
80
°
.
(1) Operating the hook
(a) Pull out the hook toward you in the direction of
arrow (A) and turn in the direction of arrow (B)
(Fig. 8).
(b) The angle can be adjusted in 5 steps (0°, 20°, 40°,
60°, 80°).
Adjust the angle of the hook to the desired position
for use.
