Blade Sharpening Ass'y; Maintenance And Inspection - Hitachi P 14DSL Mode D'emploi

English
(2) As shown in Fig. 21, slide the blade in the direction
indicated by the arrow to disassemble the blade.
2. Blade assembly
CAUTION
○ To prevent accidents, ensure that the power tool is
switched off and pull out the battery.
○ Prior to assembly, thoroughly wipe off all swarf
accumulated on the blade.
(1) Insert a turned portion of set plate (A) attached to the
blade into a groove on the fl at portion of the cutter block.
(Fig. 24, 27)
Set the blade so that both sides of the blade protrude
from the width of the cutter block by about 1 mm (Fig. 28)
(2) Place the blade holder on the completed assembly,
as shown in Fig. 29, and fasten it with the three bolts.
Ensure that the bolts are securely tightened.
(3) Turn the cutter block over, and set the opposite side in
the same manner.
3. Adjustment of blade height
(1) Loosen the 2 screws holding on the blade and set plate
(A). (Fig. 30)
(2) Press the turned surface of set plate (A) to the wall surface
b while adjusting the blade edge to the wall surface a of
the set gauge. Then, tighten them with the 2 screws. (Fig.
22, 31)
SHARPENING THE RESHARPENABLE BLADES
Use of the accessory Blade Sharpening Ass'y is
recommended for convenience.
1. Use of Blade Sharpening Ass'y
As shown in Fig. 32, two blades can be mounted on the
blade sharpening ass'y to ensure that the blade tips are
ground at uniform angles. During grinding, adjust the
position of the blades so that their edges simultaneously
contact the dressing stone as shown in Fig. 33.
2. Blade sharpening intervals
Blade sharpening intervals depend on the type of wood
being cut and the cutting depth. However, sharpening
should generally be eff ected after each 500 meters of
cutting operation.
3. Grinding allowance of the cutter blades
As illustrated in Fig. 34, a grinding allowance of 3.5mm
is provided for on the cutter blade. That is, the cutter
blade can be repeatedly sharpened until its total height
is reduced to 24.5 mm.
4. Grinding Stone
When a water grinding stone is available, use it after
dipping it suffi ciently in water since such a grinding
stone may be worn during grinding procedures, fl atten
the upper surface of the grinding stone as frequently as
possible.
ATTACHING AND DETACHING THE DUST
ADAPTER (OPTIONAL ACCESSORY)
CAUTION
○ To prevent accidents, ensure that the power tool is
switched off and pull out the battery.
○ Follow the procedure below to mount the dust adapter
securely. Failure to do so may result in the adapter
coming off , causing injury.
1. Attaching the dust adapter
(1) Remove the screw D4 × 16 in the chip cover and remove
the chip cover as shown in Fig. 35.
(2) Mount the dust adapter and secure with the screw D4 ×
16. (Fig. 36)
NOTE
Take care not to break the catch when attaching or
detaching the dust adapter and chip cover.

2. Removing the dust adapter
To remove the dust adapter, follow the procedure above
in reverse order.

MAINTENANCE AND INSPECTION

1. Inspecting the blades
Continued use of dull or damaged blades will result in
reduced cutting effi ciency and may cause overloading
of the motor. Sharpen or replace the blades as often as
necessary.
2. Handling
CAUTION
The front base, rear base, and cutting depth control
knob are precisely machined to obtain specifi cally high
precision. If these parts are roughly handled or subjected
to heavy mechanical impact, it may cause deteriorated
precision and reduced cutting performance. These parts
must be handled with particular care.
3. 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
4. Inspecting the carbon brushes (Fig. 37)
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. 999017.
5. Replacing carbon brushes
After removing the chip cover, take out the carbon brush
by fi rst removing the brush cap and then hooking the
protrusion of the carbon brush with a slotted head screw
driver, etc., as shown in Fig. 38.
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 fi nger as illustrated in Fig. 39. 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. 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.
7. Cleaning on the outside
When the planer is stained, wipe with a soft dry cloth or
a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
