Maintenance And Inspection - HIKOKI W 4YD Mode D'emploi

○ Driving blanks
During continuous screw tightening, you might not
notice you have run out of screws and continue to
operate the unit. Driving without any screws will cause
the bit to damage the lath or plaster board, so do the
screw tightening while checking the number of screws
remaining.
○ If the slider does not move smoothly, try cleaning the
sliding surfaces with an air gun, etc.
2. Using in corners (Fig. 9)
Unit can drive screws at positions as close as 15 mm
from the wall.
NOTE
○ Do not attempt to drive screws when closer to the wall
than 15 mm.
Do not drive screws while the slider case is in contact
with the wall. Damaging the screw head causes bit wear.
The proper tightening torque is not transmitted to the
screw if the screw head or bit is worn. This might also
cause the screw not to seat properly and might cause this
unit to break.
3. Using the hook
The hook can be installed on the right or left side and the
angle can be adjusted in 5 steps between 0° and 80°.
(1) Operating the hook
(a) Pull out the hook toward you in the direction of arrow
(A) and turn in the direction of arrow (B) (Fig. 10).
(b) The angle can be adjusted in 5 steps (0°, 20°, 40°,
60°, 80°).
Adjust the angle of the hook to the desired position for
use.
(2) Switching the hook position
CAUTION
Incomplete installation of the hook may result in bodily
injury when used.
(a) Securely hold the main unit and remove the screw
using a slotted head screwdriver or a coin (Fig. 11).
(b) Remove the hook and spring (Fig. 12).
(c) Install the hook and spring on the other side and
securely fasten with screw (Fig. 13).
NOTE
Pay attention to the spring orientation. Install the spring
with larger diameter away from you (Fig. 13).
4. Attaching the rubber cover (Fig. 14)
If concerned about wind coming in from the air vents,
install the accessory rubber cover over the holes to
change the direction of air fl ow.
To install the cover, press the protrusions fi rmly into the
air vents. To install easily, press inwards, in order from
the sides.
5. When the slider won't move smoothly
If the slider will not move smoothly, try cleaning the
sliding surfaces of the slider and slider case with an air
gun, etc. (Fig. 15).
NOTE
○ The unit tends to easily become covered with lath or
plaster board dust during jobs where it faces upwards.
Clean the sliding surfaces at regular periods during the
work task.
6. Attaching the sheet
If the sheet has been damaged and cannot be used,
please replace the sheet with attached one. Attach the
sheet by inserting the holes on the sheet on the two
protrusions on the stopper (Fig. 16).
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. Failure to do so may
result in serious hazard.
3. Inspecting the carbon brushes (Fig. 19)
The motor employs carbon brushes which are
consumable parts.
Since an excessively worn carbon brush can result in
motor trouble, replace the carbon brush with a new one
having the same carbon brush No. shown in the fi gure,
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.
4. Replacing carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
5. 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.
6. 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.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
