(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

⅜ 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.

⅜ 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.

⅜ 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.

ⅷ 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.

ⅷ 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:

⅜ 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.

⅜ 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.
