Hitachi WR14VBNS [7/52] English

English

2. Extension bar

The extension bar is convenient for working in very

restricted spaces or when the socket provided cannot

reach the bolt to be tightened.

CAUTION

When the extension bar is used the tightening torque

is reduced slightly compared with the ordinary

socket. So it is necessary to operate the tool a little

longer to get the same torque.

3. Universal joint

The universal joint is convenient for impacting nuts

when there is an angle between the socket and

wrench, or when working in a very narrow space.

4. Corner attachment (Model EW-14R)

Use this attachment only when the machine is

applied to the nut or bolt at a right angle.

Optional accessories are subject to change without notice.

APPLICATIONS

䡬 Tightening and loosening various kinds of bolt and

nut.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms

to the power requirements specified on the product

nameplate.

2. Power switch

Ensure that the power switch is in the OFF position.

If the plug is connected to a receptacle while the

power switch is in the ON position, the power tool

will start operating immediately, which could cause

a serious accident.

3. Extension cord

When the work area is removed from the power

source, use an extension cord of sufficient thickness

an rated capacity. The extension cord should be

kept as short as practicable.

4. Fixing the side handle

The position of the side handle attached to the

hammer case can be changed by unscrewing the

handle. (Right hand screw) Turn the handle to the

desired position for the job and secure the handle

by screwing up tight.

5. Mounting the socket

(1) Pin, O-ring type (Fig. 1)

Select a socket matched to the bolt to be tightened

or loosened. Insert the socket on the anvil of the

wrench, and secure it with the pin and ring. When

dismantling the socket, reverse the sequence.

(2) Plunger type (Fig. 2)

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

1. Check the rotational direction

The socket rotates clockwise (viewed from the rear

side) by pushing the R-side of the push button.

The L-side of the push button is pushed to turn the

socket counterclockwise (See Fig. 4) (The

and

marks are provided on the body).

CAUTION

The push button can not be switched while the

impact wrench is turning. To switch the push button,

stop the impact wrench, then set the push button.

2. Switch operation

䡬 When the trigger switch is depressed, the tool

rotates. When the trigger is released, the tool stops.

䡬 The rotational speed can be controlled by varying

the amount that the trigger switch is pulled. Speed

is low when the trigger switch is pulled slightly and

increases as the trigger switch is pulled more.

3. Using the speed change lever

As shown in Fig. 4, slide the speed change lever to

the right for high speed or slide to the left for low

speed. Use the low speed side when you want to

lower the maximum applied torque (See Fig. 5).

4. Tightening and loosening bolts

A hex socket matching the bolt or nut must first

be selected. Then mount the socket on the anvil,

and grip the nut to be tightened with the hex socket.

Holding the wrench in line with the bolt, press the

power switch to impact the nut for several seconds.

If the nut is only loosely fitted to the bolt, the bolt

may turn with the nut, therefore preventing proper

tightening. In this case, stop impact on the nut and

hold the bolt head with a wrench before restarting

impact, or manually tighten the bolt and nut to

prevent them slipping.

OPERATIONAL CAUTIONS

1. Confirm the line voltage (Fig. 5)

The available tightening torque is influenced by line

voltage. Reduced line voltage lowers the available

tightening torque.

For example, if you use a 220 V type wrench on

a 200 V line the available tightening torque will be

reduced to 70 to 90 %. When extending the power

cord, use an extension cord which is as short as

possible. When the line voltage is low and a long

extension cord is needed a step up transfomer

should be used. The relation between the line voltage

and the tightening torque are shown in the figures.
