HIKOKI WE 25SE, Handling Instructions Manual

English

1.  Switch operation (Fig. 3)

  The switch (2) in this machine functions as a motor 

switch and rotational direction selector switch. When 

the switch is set to R indicated on the handle cover, the 

motor rotates clockwise to tighten the bolt.

  When the switch is set to L, the motor rotates 

counterclockwise to loosen the bolt. When the switch is 

released, the motor stops.

2.  Operating time

  The tightening torque increases when the operating time 

increases. But the tightening torque does not increase 

above a certain value even if the tool is driven for a long 

time (See 

Fig. 5

).

3.  The protection function

  To protect the tool, the protection function will be 

activated, automatically shutting down the unit in the 

event of any problems. (

Table 1

)

Table 1

Cause of Shutdown

Automatic shutdown initiated by excessive load (*1)

Automatic shutdown initiated due to the tool’s internal 

temperature exceeding the specified temperature level (*2)

*1  Excessive load protection function

  For excessive load conditions, the tool will shutdown to 

prevent damage.

  Discontinue the heavy load task, unplug the power 

supply cord from the electrical outlet and plug it back in 

to reset.

*2  Increased temperature protection function

  Automatic shutdown is activated to prevent damage 

from high temperatures.

  The  tool’s  internal  temperature  will  increase  for  tasks 

involving the use of large currents of electricity, or when 

used in high temperature environments.

  Please allow the tool to rest for 10 to 15 minutes before 

continuing a task.

MAINTENANCE AND INSPECTION

1.  Inspecting the socket

  A worn or deformed hex or a square-holed socket will 

not give an adequate tightness to the fitting between the 

nut or anvil, consequently resulting in loss of tightening 

torque. Pay attention to wear of socket holes periodically, 

and replace with a new one if needed.

2.  Inspecting the mounting screws

  Regularly inspect all mounting screws and ensure that 

they are properly tightened. Should any of the screws be 

loose, retighten them immediately. Failure to do so could 

result in serious hazard.

3.  Maintenance of the motor

  The motor unit winding is the very “heart” of the power tool.

  Exercise due care to ensure the winding does not 

become damaged and/or wet with oil or water.

4.  Replacing supply cord

  If the replacement of the supply cord is necessary, this 

has to be done by the manufacturer of this agent in order 

to avoid a safety hazard.

CAUTION

  In the operation and maintenance of power tools, the 

safety regulations and standards prescribed in each 

country must be observed.

GUARANTEE

We  guarantee  HiKOKI  Power  Tools  in  accordance  with 

statutory/country  specific  regulation.  This  guarantee  does 

not cover defects or damage due to misuse, abuse, or 

normal wear and tear. In case of complaint, please send 

the  Power  Tool,  undismantled,  with  the  GUARANTEE 

CERTIFICATE found at the end of this Handling instruction, 

to a HiKOKI Authorized Service Center.

IMPORTANT

Correct connection of the plug

The wires of the main lead are coloured in accordance

with the following code:

Blue: — Neutral

Brown: — Live

As the colours of the wires in the main lead of this tool may 

not correspond with the coloured markings identifying the 

terminals in your plug proceed as follows:

The wire coloured blue must be connected to the terminal 

marked  with  the  letter  N  or  coloured  black.  The  wire 

coloured brown must be connected to the terminal marked 

with  the  letter  L  or  coloured  red.  Neither  core  must  be 

connected to the earth terminal.

NOTE:

This  requirement  is  provided  according  to  BRITISH 

STANDARD 2769: 1984.

Therefore, the letter code and colour code may not be 

applicable to other markets except The United Kingdom.

Information concerning airborne noise and vibration

The measured values were determined according to 

EN62841 and declared in accordance with ISO 4871.

Measured A-weighted sound power level:

106 dB (A) (WR22SE)

108 dB (A) (WR25SE)

Measured A-weighted sound pressure level:

95 dB (A) (WR22SE)

97 dB (A) (WR25SE)

Uncertainty K: 3 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined 

according to EN62841.

Impact tightening of fasteners of the maximum capacitiy of 

the tool:
Vibration emission value 

a

h = 15.2 m/s

2

Uncertainty K = 1.5 m/s

2

The declared vibration total value has been measured in 

accordance with a standard test method and may be used 

for comparing one tool with another.

It may also be used in a preliminary assessment of exposure.

WARNING

○  The  vibration emission during actual use of the power 

tool can differ from the declared total value depending in 

the ways in which the tool is used.

○ 

Identify safety measures to protect the operator that are 

based on an estimation of exposure in the actual conditions 

of use (taking account of all parts of the operating cycle 

such as the times when the tool is switched off and when it 

is running idle in addition to the trigger time).

NOTE

Due  to  HiKOKI’s  continuing  program  of  research  and 

development,  the  specifications  herein  are  subject  to 

change without prior notice.
