Avoid using the tool below temperatures of - 5°C.
If the tool is used in temperatures below - 5°C, no
torque may be generated even when it is switched
on, or the torque may be seriously reduced so that
the tool becomes overloaded which may lead to the
motor being damaged.
For continuous operations, no more than two batteries
should be used.
If the tool is operated continuously so that it becomes
excessively hot due to nonstop operations, the torque
will abruptly increase making it difficult to tighten the
screws.
If this situation occurs, shut the tool off and let it
rest for a half an hour or more.
MAINTENANCE AND INSPECTION
1. Inspecting the driver bit
Using a broken bit or one with a worn out tip is
dangerous because the bit can slip. Replace it.
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. 13)
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.
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. 15.
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. 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.
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.
