GUARD FUNCTION
a) Check the guard for proper closing before each use. Do not operate the
saw if the guard does not move freely and enclose the blade instantly. Never
clamp or tie the guard so that the blade is exposed. If the saw is accidentally
dropped, the guard may be bent. Check to make sure that the 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.
The guard may operate sluggishly due to damaged parts, gummy deposits, or a
build-up of debris.
c) Assure that the base plate of the saw will not shift while performing a
“plunge cut”.Blade shifting sideways will cause binding and likely kick back.
d) Always observe that the guard is covering the blade before placing the
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 the switch is released.
The following information applies to professional users only but is good practice
for all users:
f) Blade depth and bevel adjusting locking levers must be tight and secure
before making the cut. If blade adjustment shifts while cutting, it may cause
binding and kickback.
g) Use extra caution when sawing into existing walls or other blind areas.
The protruding blade may cut objects that can cause kickback.
ADDITIONAL SAFETY WARNING FOR CONSTRUCTION DUST
The updated Control of Substances Hazardous to Health Regulations 1st
October 2012 now also targets to reduce the risks associated with silica, wood
and gypsum dusts.
Construction workers are one of the at-risk groups within this because of the
dust that they breathe: silica dust is not just a nuisance; it is a real risk to your
lungs!
Silica is a natural mineral present in large amounts in things like sand, sandstone
and granite. It is also commonly found in many construction materials such as
concrete and mortar. The silica is broken into very fine dust (also known as
Respirable Crystalline Silica or RCS) during many common tasks such as
cutting, drilling and grinding Breathing in very fine particles of crystalline silica
can lead to the development of:
