Supports must be placed under the panel on both sides, near the
line of cut and near the edge of the panel.
e) Do not use dull or damaged blades. Unsharpened or
improperly set blades produce narrow kerf causing excessive
friction, blade binding and kickback.
f) Blade depth and bevel adjusting locking levers must be
tight and secure before making cut. If blade adjustment shifts
while cutting, it may cause binding and kickback.
g) Use extra caution when making a “plunge cut” into
existing walls or other blind areas. The protruding blade may
cut objects that can cause kickback.
SAFETY INSTRUCTIONS FOR PLUNGE- TYPE SAW
a) Check guard for proper closing before each use. Do not
operate the saw if guard does not move freely and enclose
the blade instantly. Never clamp or tie the guard with the
blade exposed. If saw is accidentally dropped, guard may be bent.
Check to make sure that guard moves freely and does not touch
the blade or any other part, in all angles and depths of cut.
b) Check the operation and condition of the guard return
spring. If the guard and the spring are not operating properly,
they must be serviced before use. Guard may operate sluggishly
due to damaged parts, gummy deposits, or a build-up of debris.
c) Assure that the guide plate of the saw will not shift while
performing the “plunge cut” when the blade bevel setting
is not at 90°. Blade shifting sideways will cause binding and likely
kick back.
d) Always observe that the guard is covering the blade before
placing saw down on bench or floor. An unprotected, coasting
blade will cause the saw to walk backwards, cutting whatever is
in its path. Be aware of the time it takes for the blade to stop after
switch is released.
GENERAL SAFETY WARNINGS FOR YOUR LASER
WARNING: Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in serious
injury.
Save all warnings and instructions for future reference.
These lasers do not normally present an optical hazard although
staring at the beam may cause flash blindness.
Do not stare directly at the laser beam. A hazard may exist if you
deliberately stare into the beam, please observe all safety rules as
follows:
The laser shall be used and maintained in accordance with the
manufacturer’s instructions.
Never aim the beam at any person or an object other than the work
piece.
The laser beam shall not be deliberately aimed at another person
and shall be prevented from being directed towards the eye of a
person for longer than 0.25 seconds area.
Always ensure the laser beam is aimed at a sturdy work piece
without reflective surfaces, e.g. wood or rough-coated surfaces
are acceptable. Bright shiny reflective sheet steel or similar is not
suitable for laser applications as the reflective surface may direct
the laser beam back at the operator.
Do not change the laser device with a different type. The
manufacturer or an authorized agent must carry out repairs.
CAUTION: Use of controls or adjustments other than those
specified herein may result in hazardous radiation exposure.
