operation, pull the switch trigger (A) and then push in the
lock lever (B). To stop the tool from the locked position,
pull the switch trigger (A) fully, then release it.
For tool with the lock-off switch
To prevent the switch trigger from accidentally pulled, a
lock lever is provided. To start the tool, push in the lock
lever (B) and then pull the switch trigger (A). Release the
switch trigger to stop.
For tool with the lock on and lock-off switch
To prevent the switch trigger from accidentally pulled, a
lock lever is provided. To start the tool, push in the lock
lever (B) and then pull the switch trigger (A). Release the
switch trigger to stop. For continuous operation, push in
the lock lever (B), pull the switch trigger (A) and then
push in the lock lever (B) further. To stop the tool from
the locked position, pull the switch trigger (A) fully, then
release it.
Electronic function
Constant speed control
Possible to get fine finish, because the rotating
•
speed is kept constantly even under the loaded
condition.
Additionally, when the load on the tool exceeds
•
admissible levels, power to the motor is reduced to
protect the motor from overheating. When the load
returns to admissible levels, the tool will operate as
normal.
Soft start feature
Soft start because of suppressed starting shock.

Indication lamp
Fig.2
The indication lamp lights up green when the tool is
plugged. If the indication lamp does not light up, the
mains cord or the controller may be defective. The
indication lamp is lit but the tool does not start even if the
tool is switched on, the carbon brushes may be worn out,
or the controller, the motor or the ON/OFF switch may be
defective.
Unintentional restart proof
Even locking lever keeping the switch trigger depressed
(Lock-on position) does not allow the tool to restart even
when the tool is plugged.
At this time, the indication lamp flickers red and shows
the unintentional restart proof device is on function.
To cancel the unintentional restart proof, pull the switch
trigger fully, then release it.
Level planing (for PC5001C only)
Fig.3
To level a surface, the base of the planer should be
aligned with the diamond wheel. The front roller should
be adjusted (use hex wrench) upward to the level
required for the desired stock removal amount.
To change the amount of stock (concrete) removed,
loosen the hex socket head bolts on the base holder with
the hex wrench. Raise or lower the front roller to adjust
the gap between it and the diamond wheel. The
difference is the stock removal amount. Then secure the
hex socket head bolts very carefully.
Fig.4
NOTE:
Maximum stock removal should be less than 4.0
•
mm.
Tilting base for smoother planing ( for
PC5001C only)
Fig.5
For smooth removal of a given surface roughness or
texture, tilting the base is helpful. Use the hex wrench to
loosen the two hex socket head bolts securing the base
on either side.
Use a hex wrench to lower the three hex socket head
bolts on the base by turning them on the base clockwise.
Fig.6
Use a square or ruler to obtain the desired base angle in
relation to the diamond wheel. Then secure carefully the
hex socket head bolts on either side of the base. Adjust
center of base near wheel so that it is on the same level
as the wheel.
Fig.7
NOTE:
After base adjustment, turn the three hex socket
•
head bolts on the base counterclockwise until the
heads are flush with the back side of the base.
Turn gently or base adjustment will be thrown off.
Base adjustment to compensate for wheel
wear (for PC5001C only)
With long use, the diamond wheel will wear and thus
create a gap with the planing surface so that
performance becomes poor. Check the tool after every 4
or 5 hours of use.
If the wheel and base surfaces are not aligned, loosen
two hex socket head bolts securing the base. Turn three
hex socket head bolts on the base clockwise and adjust
the base so as to be level with the wheel surface.
Retighten firmly the hex socket head bolts securing base
and then lightly turn the hex socket head bolts
counterclockwise so that the hex socket head bolts do
not come loose during operation.
Dust cover adjustment
Fig.8
Loosen the screw. and adjust the dust cover's brush
level. The dust cover's brush should be either flush with
the diamond wheel surface or very slightly above (when
tool is inverted) 0.5 mm. Suction/pickup will be poor if
they are not approximately on the same level. After
adjusting, be sure to tighten the screw firmly.
To adjust the dust cover, grip it on the outside; turn
clockwise to raise, counterclockwise to lower.
