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 may
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. Inspecting the carbon brushes (Fig. 12)
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 within the brush holders.
NOTE:
When replacing the carbon brush with a new one, be sure
to use the Berner Carbon Brush Code No. 999054.
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. 14.
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. 15. 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 driver 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 driver in a place in which the temperature
is less than 40°C, and out of reach of children.
