Accidental re-start preventive function
When plugging in the tool while the switch is ON, the
tool does not start.
At this time, the indication lamp blinks in red and shows
that the accidental re-start preventive function works.
To start the tool, turn off the switch, and turn it on again.
Constant speed control
Possible to get fine finish, because the rotating speed is
kept constantly even under the loaded condition.
Soft start feature
Soft start feature reduces starting reaction.
Overload protector
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 lev-
els, the tool will operate as normal.
Level planing
Only for model PC5001C
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.
► Fig.4: 1. Base 2. Hex wrench 3. Front roller
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
the front roller and the diamond wheel.
The difference is the stock removal amount.
Then secure the hex socket head bolts very carefully.

NOTE: Maximum stock removal should be less than
4.0 mm.
Tilting base for smoother planing
Only for model PC5001C
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 which secure the base on either side.
► Fig.6: 1. Base 2. Hex wrench 3. Hex socket head bolt
Use a hex wrench to lower the three hex socket head
bolts on the base by turning them clockwise.
► Fig.7: 1. Hex wrench 2. Hex socket head bolt
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.

NOTICE:
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 them gently, or base adjustment will be thrown
off.
Base adjustment to compensate for
wheel wear
Only for model PC5001C
With long use, the diamond wheel will wear and thus
create a gap with the planing surface so that perfor-
mance 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.9: 1. Raise 2. Lower 3. Dust cover 4. Screw
Loosen the screw, and adjust the dust cover brush
level.
The dust cover brush should be either flush with the
diamond wheel surface or up to 0.5 mm above the
diamond wheel surface (when the tool is inverted).
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.
ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and unplugged before carrying out
any work on the tool.
Installing or removing loop handle
CAUTION:
Always install the loop handle
before operation.
CAUTION:
Always be sure the bolts on the
loop handle is securely tightened before use.
CAUTION:
Hold the gripping area of the loop
handle specified in the figure. Also, keep the
hand away from the metal part of the tool during
operation. Touching the metal part may result in
electric shock, if the cutting attachment cuts live wire
unexpectedly.
To install the loop handle, mount it onto the tool as
illustrated and tighten two bolts to fix it.
To remove the loop handle, follow the installation proce-
dure in reverse.
