Makita 5017RKB Instruction Manual page 7

11. Lower Guard.
Raise lower guard with the retracting handle.
12. Adjustments.
Before cutting be sure depth and bevel adjust-
ments are tight.
13. Use Only Correct Blades In Mounting.
Don't use blades with incorrect size holes. Never
use defective or incorrect blade washers 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 cut-
ting operation. Operate with proper hand sup-
port, proper workpiece support, and supply cord
routing away from the work area.
WARNING:
It is important to support the workpiece properly
and to hold the saw firmly to prevent loss of con-
trol 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 example, 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 vice. This is extremely danger-
ous 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 com-
plete 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.

OPERATING INSTRUCTIONS
Removing or installing saw blade
CAUTION:
Always be sure that the tool is switched off and
unplugged before installing or removing the saw blade.
The following blade can be used with this tool.
Max. dia. Min. dia.
190 mm 170 mm
The thickness of the riving knife is 1.8 mm.
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.
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. (Fig. 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).
• Use only the Makita hex wrench to remove or install the
blade.
Riving knife adjustment (Fig. 11)
Move the base and raise the safety cover. Then use the
hex wrench to loosen the hex head socket bolt for the riv-
ing knife adjustment. 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 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 side of rear handle 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 workpiece
for cleaner, safer cuts.
• After adjusting the depth of cut, always tighten the lever
securely.
