Maintenance And Inspection - Hitachi G 14DSL Bedienungsanleitung

English
As the remaining battery indicator shows somewhat
differently depending on ambient temperature and
battery characteristics, read it as a reference.
NOTE
Do not give a strong shock to the switch panel or
break it.It may lead to a trouble.
To save the battery power consumption, the
remaining battery indicator lamp lights while
pressing the remaining battery indicator switch.
ASSEMBLING AND DISASSEMBLING THE
DEPRESSED CENTER WHEEL (Fig. 6)
CAUTION: Be sure to turn off the switch and pull out the
battery.
1. Assembling (Fig. 6)
(1) Turn the disc grinder upsidedown so that the spindle
is facing upward.
(2) Align the across flats of the wheel washer with the
notched part of the spindle, then attach them.
(3) Fit the protuberance of the depressed center wheel
onto the wheel washer.
(4) Screw the wheel nut onto the spindle.
(5) While pushing the push button with one hand, lock
the spindle by turning the depressed center wheel
slowly with the other hand.
Tighten the wheel nut by using the supplied wrench
as shown in Fig. 6.
2. Disassembling
Follow the above procedures in reverse.
CAUTIONS
Confirm that the depressed center wheel is mounted
firmly.
Confirm that the push button is disengaged by
pushing push button two or three times before
switching the power tool on.

MAINTENANCE AND INSPECTION

1. Inspecting the depressed center wheel
Ensure that the depressed center wheel is free of
cracks and surface defects.
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. 8)
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 slotted head screw driver, etc.,
as shown in Fig. 10.
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.
11. 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 cordless disc grinder 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 cordless disc grinder 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.
NOTE
Storing lithium-ion batteries
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage of batteries with a low charge
may result in performance deterioration, significantly
reducing battery usage time or rendering the
batteries incapable of holding a charge.
However, significantly reduced battery usage time
may be recovered by repeatedly charging and using
the batteries two to five times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries
dead and purchase new batteries.
8. Service parts list
