Maintenance And Inspection - HIKOKI WF 18DSL Instrucciones De Manejo

English
○ Attempting to tighten one screw on top of another will
cause the screw to fall or stop the screw feed so use
caution.
○ 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. 16)
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. Removing the screws
The tightened screws can be removed by rotating them
for the reverse rotation
Properly install the bit against the groove on the screw
head, and pull the switch trigger while depressing the
bit against the groove vertically.
Or, depress the bit against the groove on the screw
head vertically while pulling the switch trigger.
4. 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. 17).
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.
5. 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. 18).
6. Using the hook
The hook is used to hang up the power tool to your waist
belt while working.
CAUTION
○ When using the hook, hang up the power tool firmly not
to drop accidentally.
If the power tool is dropped, it may lead to an accident.
○ When carrying the power tool with hooked to your waist
belt, do not fit any bit to the tip of power tool. If the sharp
bit such as drill is fitted to the power tool when carrying
it with hooked to your waist belt, you will be injured.
○ Install securely the hook. Unless the hook is securely
installed, it may cause an injury while using.
(1) Removing the hook.
Remove the screws fixing the hook with Philips screw
driver. (Fig. 19)
(2) Replacing the hook and tightening the screws.
Install securely the hook in the groove of power tool and
tighten the screws to fix the hook firmly. (Fig. 20)
7. About Remaining Battery Indicator
When pressing the remaining battery indicator switch,
the remaining battery indicator lamp lights and the
battery remaining power can be checked. (Fig. 21)
14
(counterclockwise).
When releasing your finger from the remaining battery
indicator switch, the remaining battery indicator lamp
goes off. The Table 4 shows the state of remaining
battery indicator lamp and the battery remaining power.
State of lamp
The battery remaining power is
enough.
The battery remaining power is
a half.
The battery remaining power is
nearly empty.
Re-charge the battery soonest
possible.
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.
8. Confirm that the battery is mounted correctly
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
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. 22)
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 HiKOKI Carbon Brush Code No.
