Removing or installing saw blade (Fig. 14 & 15)
The following blade can be used with this tool.
006481
The thickness of the riving knife is 1.8 mm for Model
5705R, 2.0 mm for Models 5903R and 5103R, and
2.5 mm for Model 5143R.
CAUTION:
• Do not use saw blades which do not comply with the
characteristics specified in these instructions.
• Do not use saw blades the disc of which is thicker or
the set of which is smaller than the thickness of the riv-
ing knife.
CAUTION:
• Be sure the blade is installed with teeth pointing up at
the front of the tool.
• Use only the Makita wrench to install or remove the
blade.
• Never depress the shaft lock while the saw is running.
To remove the blade, press the shaft lock fully so that the
blade cannot revolve and use the hex wrench to loosen
the hex bolt counterclockwise. Then remove the hex bolt,
outer flange and blade.
To install the blade, follow the removal procedure in
reverse. BE SURE TO TIGHTEN THE HEX BOLT
CLOCKWISE SECURELY.
When changing blade, make sure to also clean upper
and lower blade guards of accumulated sawdust. Such
efforts do not, however, replace the need to check lower
guard operation before each use.
Connecting a vacuum cleaner (Fig. 16)
When you wish to perform clean cutting operation, con-
nect a Makita vacuum cleaner to your tool. Install the joint
on the tool using the screws. Then connect a hose of the
vacuum cleaner to the joint as shown in the figure.
OPERATION
CAUTION:
• Be sure to move the tool forward in a straight line
gently. Forcing or twisting the tool will result in
overheating the motor and dangerous kickback,
possibly causing severe injury.
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 fol-
low 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 a 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.
(Fig. 17)
CAUTION:
• The riving knife should always be used except when
plunging in the middle of the workpiece.
Rip fence (Guide rule) (Fig. 18)
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.
Replacing carbon brushes (Fig. 19 & 20)
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.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
