Maintenance; Ec Declaration Of Conformity - Makita 4157KB Instruction Manual

Operation (Fig. 11)
Grasp the rear handle with your right hand, the front grip
with your left. Set the base plate on the workpiece to be
cut without the wheel making any contact. Then turn the
tool on and wait until the wheel attains full speed. Now
simply move the tool forward over the workpiece surface,
keeping it flat and advancing smoothly until the cutting is
completed. To get clean cuts, keep your cutting line
straight and your speed of advance uniform. Never use
water when cutting. Water may enter the tool, causing an
electric shock hazard.
CAUTION:
• Be sure to move the tool 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 kick-
back of the tool.
• 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 progressively
deeper settings.
Rip fence (guide rule) (Optional accessory)
(Fig. 12)
The handy rip fence (guide rule) allows you to do extra-
accurate straight cuts. Simply slide the rip fence up
snugly against the side of the workpiece and secure it in
position with the clamp screw on the front of the base. It
also makes repeated cuts of uniform width possible.
Dust extraction (Fig. 13)
This tool equipped with a dust box to collect dust and cut
chips. When the dust box is about two thirds full, empty
its contents. To do so, press the lever to unlock the dust
cap. Then open it. Cleaner cutting operations can be per-
formed by connecting this tool to a Makita vacuum
cleaner. Remove the rubber cap from the dust cap and
connect the vacuum cleaner hose to the dust cap.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Replacement of carbon brushes (Fig. 14 &15)
Replace carbon brushes when they are worn down to the
limit mark. Both identical carbon brushes should be
replaced at the same time.
Dressing diamond wheel
If the cutting action of the diamond wheel begins to
diminish, use an old discarded coarse grit bench grinder
wheel or concrete block to dress the diamond wheel. To
do this, tightly secure the bench grinder wheel or con-
crete block and cut in it.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
