8-8. Cutting Work

Precautions on cutting work are provided in the Instruction Manual. Read them carefully and advise the user on
correct operation. In this section, important items and the items not described in the Instruction Manual are
explained to help you advise the user.
(1) For cutting work, be sure to use the saw blade guard and check that everything functions properly.
1 Check that the saw blade guard rises smoothly.
2 Remove wood chips in the guard and wipe off the swarf on the guard with a soft cloth.
3 Check that the dislodging preventive claw (anti-kickback pawls) works normally and is sharp at the tip.
(For the U.S.A., Australia and New Zealand)
4 Check that the screw fastening the spreader is not loose.
(2) When using the miter gauge and rip fence, be sure to secure them firmly before starting operation.
(3) Before starting operation, be sure to tighten the tilt lock handle for raising and tilting saw blade.
(4) Remove the swarf in the miter-gauge groove.
(5) Do not raise the saw blade excessively.

(6) The standard precision values are provided in 10-5. Product Precision.
Advise the user to check the precision before starting cutting work. If the precision is insufficient, it may cause
dislodging of the workpiece or other unexpected accidents, resulting in poor cutting precision.
(7) The set nut securing the saw blade is naturally tightened.
Advise the user to check the set nut is firmly tightened before starting operation, and also to remove the plug
at this time.
(8) Use of work helpers.
Assembling and procedures for use of work helpers:
Work helpers are essential for safe operation. Give careful advice on this point. Many books are available on
the market relating to work helpers and use of table saws. Recommend the user to purchase such books.
