rim does not extend more than 5 mm beyond the
lower edge of the riving knife.
Adjusting depth of cut (Fig. 12)
Loosen the lever on the depth guide and move the
base up or down. At a desired depth of cut, secure
the base by tightening the lever.
CAUTION:
• Use a shallow depth of cut when cutting thin work-
piece for cleaner, safer cuts.
• After adjusting the depth of cut, always tighten the
lever securely.
Adjusting for bevel cuts (Fig. 13)
Loosen the thumb nuts in front and back, and tilt the
tool to the desired angle for bevel cuts (0 – 45°).
Secure the thumb nuts tightly in front and back after
making the adjustment.
Sighting (5603R, 5703R) (Fig. 14)
For straight cuts, align the right notch on the front of
the base with your cutting line on the workpiece. For
45° bevel cuts, align the left notch with it.
Top guide (5903R, 5103R) (Fig. 15)
Align your sight line with either the 0° notch for
straight cutting or the 45° notch for 45° angle cuts.
Top guide (5143R) (Fig. 16)
Align your sight line with either the 0° notch for
straight cutting or the 30° notch for 30° angle cuts or
the 45° notch for 45° angle cuts or the 60° notch for
60° angle cuts.
Switch action (Fig. 17)
CAUTION:
• Before plugging in the tool, always check to see
that the switch trigger actuates properly and returns
to the "OFF" position when released.
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided. To start the tool,
depress the lock-off button and pull the switch trigger.
Release the switch trigger to stop.
Operation (Fig. 18)
Hold the tool firmly. Set the base plate on the work-
piece 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.
CAUTION:
• The riving knife should always be used except
when plunging in the middle of the workpiece.
• Do not stop the saw blade by lateral pressure on
the disc.
Guide rule (Fig. 19)
The handy guide rule allows you to do extra-accurate
straight cuts. Simply slide the guide rule 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.
Joint assembly (Fig. 20 & 21)
(for connecting a vacuum cleaner)
When you wish to perform clean cutting operation,
connect a vacuum cleaner to your tool. Install the
joint on the tool using the screw. Then connect a
hose of vacuum cleaner to the joint.

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. 22 & 23)
Replace carbon brushes when they are worn down to
the limit mark. Both identical carbon brushes should
be replaced at the same time.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by
a Makita Authorized Service Center.
