Lower Guard Function - Dremel 670 Original Instructions Manual

of the blade, but not in line with the blade. Kickback could cause the
saw to jump backwards, but kickback forces can be controlled by the
operator, if proper precautions are taken.
b. 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.
c. When restarting a saw in the workpiece, centre the saw blade in
the kerf so that the saw teeth are not engaged into the material. If
a saw blade binds, it may walk up or kickback from the workpiece as
the saw is restarted.
d. Support large panels to minimise 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.
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 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.
SAFETY INSTRUCTIONS FOR SAWS WITH PENDULUM
GUARD AND SAWS WITH TOW GUARD

LOWER GUARD FUNCTION

a. Check the lower guard for proper closing before each use. Do
not operate the saw if he lower guard does not move freely and
close instantly. Never clamp or tie the lower guard into the open
position. If the saw is accidentally dropped, the lower guard may
be bent. Raise the lower guard with the retracting handle and make
sure it moves freely and does not touch the blade or any other part, in
all angles and depths of cut.
b. Check the operation of the lower guard spring. If the guard and the
spring are not operating properly, they must be serviced before
