Maintenance - Makita 4101RH Betriebsanleitung

Installing or removing diamond wheel
Important:
Always be sure that the machine is switched off and
unplugged before installing or removing the wheel.
Hold the outer flange with the wrench and loosen the
hex socket head bolt in clockwise direction with the
hex wrench. Then remove the hex socket head bolt
and outer flange. (Fig. 3)
Install the diamond wheel, outer flange and hex
socket head bolt onto the spindle. Hold the outer
flange with the wrench and tighten the hex socket
head bolt in counterclockwise direction with the hex
wrench. BE SURE TO TIGHTEN THE HEX SOCKET
HEAD BOLT SECURELY. (Fig. 4)
CAUTION:
Use only the Makita wrench and hex wrench to install
or remove the wheel.
Adjusting depth of cut (Fig. 5)
Loosen the wing bolt on the depth guide and move the
base up or down. At the desired depth of cut, secure
the base by tightening the wing bolt.
Adjusting bevel angle
Loosen the wing nut on the bevel scale plate on the
front of the base. Set for the desired angle (0 - 45°) by
tilting accordingly, then tighten the wing nut securely.
(Fig. 6)
Loosen the wing bolt on the depth guide and move the
base so that the end of the blade case is above the
red line on the depth guide. Then tighten the wing bolt
to secure the base. (Fig. 7)
NOTE:
If the end of the blade case is under the red line on the
depth guide, the outer flange may hit the workpiece
when you perform the bevel cut.
Portable residual current device (Fig. 8)
Connect the machine to a power supply and test the
portable residual current device (PRCD) before using
the machine. Push the ''ON'' button and confirm that
the pilot lamp lights. Push the ''TEST'' button and
confirm that the pilot lamp goes out. Push the ''ON''
button again to use the machine.
WARNING:
Do not use the machine if the pilot lamp does not go
out when the ''TEST'' button is pushed.
Switch action (Fig. 9)
CAUTION:
Before plugging in the machine, always check to see
that the switch trigger actuates properly and returns to
the ''OFF'' position when released.
To prevent the trigger from being accidentally pulled,
a lock-off button is provided. To start the machine,
press the lock-off button and pull the trigger. Release
the trigger to stop.
Sighting (Fig. 10)
For straight cuts, align the left edge of the base with
your cutting line on the workpiece. For 45° bevel cuts,
align the left edge of the top guide with it.
Operation (Fig. 11)
Adjust the amount of water flow. Hold the machine
firmly. Set the base plate on the workpiece to be cut
without the wheel making any contact. Then turn the
machine on and wait until the wheel attains full speed.
Now simply move the machine forward over the
workpiece surface, keeping it flat and advancing
smoothly until the cutting is completed. Keep your
cutting line straight and your speed of advance uni-
form.
CAUTION:
• THIS MACHINE SHOULD ONLY BE USED ON
HORIZONTAL SURFACES.
• Be sure to move the machine forward in a straight
line and gently. Forcing and exerting excessive
pressure or allowing the wheel to bend, pinch or
twist in the cut can cause overheating of the motor
and dangerous kickback of the machine.
• Since excessive cutting may cause overload of the
motor, the depth of cut should not be more than 20
mm at a pass. When you wish to cut more than 20
mm deep, make a couple of passes with progres-
sively deeper settings.

MAINTENANCE

CAUTION:
Always be sure that the machine is switched off and
unplugged before carrying out any work on the
machine.
After use
Blow away dust from the inside of the machine by
running the machine at an idle for a while. Brush off
accumulation of dust on the base. Accumulation of
dust in the motor or on the base may cause a
malfunction of the machine.
Cleaning covers
When accumulation of dust on the cover (A) looks
excessive, loosen the clamp and remove the cover
(A). Wash off accumulation of dust inside the cover
(A) and wipe it. Then place its brim below, install it as
far as it will go and secure it by tightening the clamp.
(Fig. 12)
When changing the wheel, clean the cover (B) at the
same time. Loosen the screw securing the cover (B)
and remove the cover (B). Wash off accumulation of
dust inside the cover (B) and wipe it. Then attach the
cover (B) to the machine by tightening the screw.
Accumulation of dust inside the covers may cause a
mulfunction of the machine. (Fig. 13)
CAUTION:
When using the machine, be sure to attach the covers
(A) and (B).
