12. Adjustments.
Before cutting be sure depth and bevel
adjustments are tight.
13. Use Only Correct Blades In Mounting.
Don’t use blades with incorrect size holes.
Never use defective or incorrect blade wash-
ers or bolts.
14. Avoid Cutting Nails.
Inspect for and remove all nails from lumber
before cutting.
15. When operating the saw, keep the cord away
from the cutting area and position it so that it
will not be caught on the workpiece during
the cutting operation.
Operate with proper hand support, proper
workpiece support, and supply cord routing
away from the work area.
WARNING:
It is important to support the workpiece prop-
erly and to hold the saw firmly to prevent loss
of control which could cause personal injury.
Fig. 4 illustrates typical hand support of the
saw.
16. Place the wider portion of the saw base on
that part of the workpiece which is solidly
supported, not on the section that will fall off
when the cut is made.
As examples, Fig. 5 illustrates the RIGHT way
to cut off the end of a board, and Fig. 6 the
WRONG way. If the workpiece is short or
small, clamp it down. DON’T TRY TO HOLD
SHORT PIECES BY HAND! (Fig. 6)
17. Never attempt to saw with the circular saw
held upside down in a vise. This is extremely
dangerous and can lead to serious accidents.
(Fig. 7)
18. Before setting the tool down after completing
a cut, be sure that the lower (telescoping)
guard has closed and the blade has come to
a complete stop.
19. Using manufacturer data
• Ensure that the diameter, thickness and
other characteristics of the saw blade are
suitable for the tool.
• Ensure that the saw blade is suitable for the
spindle speed of the tool .
20. Do not use any abrasive wheel.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Removing or installing saw blade
The following blade can be used with this tool.
The thickness of the riving knife is 1.8 mm for Models
5603R and 5703R or 2.0 mm for Model 5903R and
5103R or 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 riving knife.
To remove the saw blade, depress the shaft lock fully
to prevent shaft rotation, then use the hex wrench to
loosen the hex socket head bolt. (Fig. 8)
Now remove the outer flange, raise the safety cover
as much as possible, and remove the saw blade.
(Fig. 9)
Install the saw blade using the reverse of the removal
procedure. Install the inner flange, saw blade, outer
flange and hex socket head bolt, in that order. Be
sure to secure the hex socket head bolt tightly with
the shaft lock fully depressed. (Fig. 8 &10)
CAUTION:
• Make sure that the blade teeth point forward in the
same direction as the tool rotation (the arrow on the
blade should point in the same direction as the
arrow on the tool).
• Never depress the shaft lock while the saw is run-
ning.
• Use only the Makita socket wrench to remove or
install the blade.
Riving knife adjustment (Fig. 11)
Use the socket wrench to loosen the hex head socket
bolt for the riving knife adjustment, then raise the
safety cover. Move the riving knife up or down over
the two protuberances for settings indicated in the
illustration, so as to obtain the proper clearance
between the riving knife and saw blade.
CAUTION:
Ensure that the riving knife is adjusted such that: The
distance between the riving knife and the toothed rim
of the saw blade is not more than 5 mm. The toothed
