21. The saw blades body must be thinner than the
riving knife and the width of cut, or kerf (with
teeth set) must be greater than the thickness of
the riving knife.
22. Never operate the circular saw with the saw blade
turned upward or the side.
23. Ensure that the material is free of foreign matters
such as nails.
24. The riving knife should always be used except
when plunging in the middle of the workpiece.
25. The saw blades range should be from 165 mm
to 150 mm.
26. Be careful of brake kickback.
This circular saw features an electric brake that
functions when the switch is released. As there
is some kickback when the brake functions, be
sure to hold the main body securely.
27. Avoid cutting in the state where the base has
floated up from the material.
When blade is binding, or when interrupting a cut
for any reason, release the trigger and hold the
saw motionless in the material until the blade
comes to a complete stop. Never attempt to
remove the saw from the work or pull the saw
backward while the blade is in motion or KICKBACK
may occur. Investigate and take corrective actions
to eliminate the cause of blade binding.
28. Support large panels to minimize the risk of blade
pinching and KICKBACK. Large panels tend to sag
under their own weight. Supports must be placed
under the panel on both sides, near the line of
cut and near the edge of the panel as shown in
Fig. 1.
To minimize the risk of blade pinching and kickback.
When cutting operation requires the resting of the
saw on the work piece, the saw shall be rested
on the larger portion and the smaller piece cut
off.
29. Use extra caution when making a “Pocket Cut”
into existing walls or other blind areas. The
protruding blade may cut objects that can cause
KICKBACK.
NEVER place your hand or fingers behind the saw
(Fig. 3). If kickback occurs, the saw could easily
jump backwards over your hand, possibly causing
severe injury.
30. WARNING: It is important to support the work
piece properly 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.
31. Place the wider portion of the saw base on that
part of the work piece 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 board, and Fig. 6 the
WRONG way. If the work piece is short or small,
clamp is down.
DON’T TRY TO HOLD SHORT PLACES BY HAND!
32. 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)
33. When the brake becomes ineffective, replace the
carbon brushes with new ones.
