Maintenance And Inspection - Hitachi DV 14DL Bedienungsanleitung

English
Use batteries correctly in accordance with the battery
specifications and indications.
14. Using the bit holder
CAUTION
Stow the bit in the specified location on the tool. If
the tool is used with the bit stowed improperly, the
bit may fall and cause bodily injury.
Do not stow bits that are of a different length, gauge
or dimension than the plus driver bit (65 mm long)
included in the STANDARD ACCESSORIES.
The bit may fall and cause bodily injury.
(1) Removing the bit
Securely hold the main unit and pull out the bit by
holding the tip with your thumb (Fig. 20).
(2) Installing the Bit
Install the bit with steps opposite of when removing.
Insert the bit so that the right and left sides are equal,
as shown in Fig. 21.
15. Installing/Removing the side handle
CAUTION
Firmly install the side handle. If loose, the side handle
may gyrate or fall out and cause bodily injury.
(1) Install the side handle so that the protrusions on the
main unit and grooves on the side handle interlock.
Tighten the grip after checking that the side handle is
not riding on the slip prevention protrusion (Fig. 22).
(2) Loosen the grip to remove the side handle.

MAINTENANCE AND INSPECTION

1. Inspecting the tool
Since use of as dull tool will degrade efficiency and
cause possible motor malfunction, sharpen or replace
the tool as soon as abrasion is noted.
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. Inspecting the carbon brushes (Fig. 23)
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 Hitachi 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 flat head screw driver, etc., as
shown in Fig. 25.
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. 26. Lastly, install
the brush cap.
13
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 on the outside
When the Impact driver drill is stained, wipe with a
soft dry cloth or a cloth moistened with soapy water.
Do not use chloric solvents, gasoline or paint thinner,
for they melt plastics.
7. Storage
Store the Impact driver drill in a place in which the
temperature is less than 40°C and out of reach of children.
