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 NPC5001C 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 NPC5001C 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 NPC5001C 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.
ASSEMBLY
CAUTION:
•
Always be sure that the tool is switched off and
unplugged before carrying out any work on the
tool.
Installing or removing diamond wheel
Fig.9
To replace a worn diamond wheel with a new one, press
in the shaft lock to hold the shaft steady, then loosen the
lock nut counterclockwise with the lock nut wrench
provided.
Remove the worn diamond wheel.
To install a new one, follow the above removal
procedure in reverse.
When installing a diamond wheel, always make sure to
tighten the lock nut firmly.
NOTE:
•
The ordinary diamond wheels on the market have
no exhaust holes, so dust evacuation is poor. Also,
if the installing hole is not of the exact diameter,
tool vibration occurs and accidents can occur.
ALWAYS USE A MAKITA OFFSET DIAMOND
WHEEL.
Replacing dust cover's brush
To remove the dust cover's brush from the dust cover,
grab an end of the dust cover's brush and take it out
slowly.
Fig.10
To install the dust cover's brush, firstly align the both
ends of the brush with the groove of the dust cover.
Fig.11
And then insert the brush all the way into the groove of
the dust cover by using slotted driver or other
appropriate tool.
