Operational Cautions; Maintenance And Inspection - Hitachi WF 4DY Bedienungsanleitung

English

OPERATIONAL CAUTIONS

1. After continuous work, allow the screwdriver to
rest
When you replace the battery after continuously
using the screwdriver to tighten screws, let the
screwdriver rest for about 15 minutes.
If you continue using the screwdriver immediately
after replacing the battery, the motor and switch
etc. may become very hot, and may burn out.
2. To screw in screws, hold the driver straight against
the workpiece.
If the driver is slanted relative to the screw, the
screw head can be damaged and the bit worn.
Moreover, the prescribed torque is not transmitted
to the screw, resulting in screws left sticking out.
3. When screwing in, press the main body firmly until
the screw is completely screwed in.
Relaxing your pressure on the driver while screwing
in can leave the screw sticking out.
4. Do not you screw in a screw on top of another
screw.
If you do, the screw falls over and the next screw
can not be fed.
5. Precautions for empty strikers:
When you are screwing in colleted screw strips, you
might continue to use the driver without noticing
that you have run out of screws. If you try to screw
in when you are out of screws, the bit can damage
the gypsum board, so while working, keep an eye
on how many screws you have left.
6. 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.
7. When the slider does not move smoothly
Clean the slider, sliding surface of the slider case
and roller of the upper part of the slider. (Fig. 20)

NOTE:
The operator may become covered with plaster
dust quite easily when operation is performed in
an upward direction. Clean the slide surface and
roller periodically during operation.

SCREW HANDLING
NOTE:
Handle both the packed box of screws and the collated
screw strips with care. If you drop them, screws can
come out of the collated tape and cause screw feed
malfunctions. Do not expose the screws to prolonged
periods of direct sunlight or outside air. They can cause
rust and collated tape problems, so when you will not
be using the screws for awhile, put them in the screw
packing box or the like.

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 by
a new one.
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. Fail-
ure to do so may result in serious hazard.
3. Cleaning of the outside
When the automatic screwdriver 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.
4. Storage
Store the automatic screwdriver in a place in which
the temperature is less than 40°C, and out of reach
of children.
