Operational Cautions; Maintenance And Inspection - Hitachi WM 14DBL Bedienungsanleitung

NOTE:
To prevent the battery power consumption caused
by forgetting to turn off the LED light, the light goes
off automatically in about 15 minutes.
8. Tightening and loosening screws
Install the bit that matches the screw, line up the bit in
the grooves of the head of the screw, then tighten it.
Push the tool just enough to keep the bit fitting the
head of the screw.
CAUTION:
Applying the tool for too long tightens the screw too
much and can break it.
Tightening a screw with the tool at an angle to that
screw can damage the head of the screw and the
proper force will not be transmitted to the screw.
Tighten with this tool lined up straight with the screw.

OPERATIONAL CAUTIONS

1. Continuous operation
When you perform the striking operation
continuously, the temperature protection circuit may
be activated early. (Refer to "2. Characteristics of
Electronic Pulse Driver" on page 12.)
When the activated temperature protection circuit
stops the tool, the LED light flashes to indicate that
the tool is heated to high temperature. The LED light
goes off automatically after approx. 30 seconds.
When you perform continuous operation, allow the
tool to rest for around 15 minutes at a replacement of
rechargeable battery.
NOTE:
When the tool is stopped by the activated temperature
protection circuit, allow the tool to cool sufficiently.
You can use the tool again when it cools down.
While the tool is not cooled sufficiently, it cannot
start up by turning the switch to on. The LED light
flashes while the switch is turned on. Please wait
until the tool cools down sufficiently.
Do not touch the nose part of the tool during
continuous operation. It is heated to high temperature.
2. Cautions on use of the speed control switch
This switch has a built-in, electronic circuit which
steplessly varies the rotation speed. Consequently, when
the switch trigger is pulled only slightly (low speed
rotation) and the motor is stopped while continuously
driving in screws, the components of the electronic
circuit parts may overheat and be damaged.
3. Holding the tool and applying the pressing force
Make sure to hold the tool securely with your both hands,
and keep the tool straight to a screw or bolt. There is no
need to press the tool excessively against materials.
Be careful not to apply excessive pressing/prying
force to the tool. It may damage the tool.
Operation
Bolt tightening
Woodwork drilling
Steel drilling
Mortar drilling
Use the bit that fits the cross recess on the screw head.
Make sure to use an appropriate bit especially when
tightening self drilling screws since using an
inappropriate bit can topple the screws.
9. Work amount possible with one charging
The following table shows the approximate amount
of work to be carried out by the tool with one charging.
(The number of screws tightened and that of boring
operations differ slightly according to the hardness
of wood or metal, the ambient temperature, the
charger properties, etc.)

MAINTENANCE AND INSPECTION

1. Inspecting the tool
Since use of a 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 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. Cleaning of the outside
When the tool 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.
5. Storage
Store the tool in a place in which the temperature is
less than 40°C, and out of reach of children.
6. Service parts list
CAUTION:
Repair, modification and inspection of Hitachi Power
Tools must be carried out by a Hitachi Authorized
Service Center.
This Parts List will be helpful if presented with the
tool to the Hitachi Authorized Service Center when
requesting repair or other maintenance.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
