4. Inspecting the carbon brushes (Fig. 9)
The motor employs carbon brushes which are
consumable parts. Since and excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with new ones when it becomes worn to or
near the "wear limit". In addition, always keep carbon
brushes clean and ensure that they slide freely whthin
the brush holders.
NOTE:
When replacing the carbon brush with a new one, be
sure to use the Hitachi Carbon Brush Code No. 328481.
5. Replacing carbon brushes
Take out the carbon brush by first removing the
brush cap and then hooking the protrusion of the
carbon brush with a slotted head screw driver, etc.,
as shown in Fig. 11.
When installing the carbon brush, choose the direction
so that the nail of the carbon brush agrees with the
contact portion outside the brush tube. Then push it
in with a finger as illustrated in Fig. 12. Lastly, install
the brush cap.
CAUTION:
Be absolutely sure to insert the nail of the carbon
brush into the contact portion outside the brush
tube. (You can insert whichever one of the two
nails provided.)
Caution must be exercised since any error in this
operation can result in the deformed nail of the
carbon brush and may cause motor trouble at an
early stage.
6. Cleaning of the outside
When the impact wrench is stained, wipe with a soft
dry cloth or a cloth moistened with soapy water. Do
not use chloric solvents, gasoline or paint thinner, as
they melt plastics.
7. Storage
Store the impact wrench in a place in which the
temperature is less than 40°C, and out of reach of
children.
NOTE:
Make sure that the battery is fully charged when
stored for a long period (3 months or more). The
battery with smaller capacity may not be able to be
charged when used, if stored for a long period.

Information concerning airborne noise and vibration
The measured values were determined according to
EN60745 and declared in accordance with ISO 4871.
Measured A-weighted sound power level: 105 dB (A)
Measured A-weighted sound pressure level: 94 dB (A)
Uncertainty KpA: 3 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN60745.
Impact tightening of fasteners of the maximum capacity
of the tool:
Vibration emission value
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
on 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).
