6. Replacing carbon brushes
Take out the carbon brush by first removing the
brush cap and then hooking the protrusion of the
carbon brush
R
with a slotted head screw driver,
etc., as shown in Fig. 15.
When installing the carbon brush, choose the direction
so that the nail of the carbon brush
Q
agrees with the
contact portion outside the brush tube
S
. Then push
it in with a finger as illustrated in Fig. 16. 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.

Cleaning of the outside
When the impact driver and impact wrench are
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.
8. Storage
Store the impact driver and impact wrench in a place
in which the temperature is less than 40°C, and out of
reach of children.
