Maintenance; Replacing Carbon Brushes - Makita 5007NB Instruction Manual

Hold the tool firmly. The tool is provided with both a front
grip and rear handle. Use both to best grasp the tool. If
both hands are holding saw, they cannot be cut by the
blade. Set the base on the workpiece to be cut without
the blade making any contact. Then turn the tool on and
wait until the blade attains full speed. Now simply move
the tool forward over the workpiece surface, keeping it
flat and advancing smoothly until the sawing is
completed.
To get clean cuts, keep your sawing line straight and your
speed of advance uniform. If the cut fails to properly
follow your intended cut line, do not attempt to turn or
force the tool back to the cut line. Doing so may bind the
blade and lead to dangerous kickback and possible
serious injury. Release switch, wait for blade to stop and
then withdraw tool. Realign tool on new cut line, and start
cut again. Attempt to avoid positioning which exposes
operator to chips and wood dust being ejected from saw.
Use eye protection to help avoid injury.
Rip fence (Guide rule) (optional accessory)
1
001480
The handy rip fence 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 screw on the front of the base. It also makes repeated
cuts of uniform width possible.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
•
like. Discoloration, deformation or cracks may
result.
Adjusting for accuracy of 90° cut (vertical cut)
This adjustment has been made at the factory. But if it is
off, adjust the adjusting screw with a hex wrench while
squaring the blade with the base using a triangular rule,
try square, etc.

Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps.
