forces can be controlled by the operator, if proper
precautions are taken.
b) When blade is binding, or when inter rupting a
cut for any reason, release the trigger and hold
the saw motion less in the material until the
blade comes to a complete stop. Never at tempt
to remove the saw from the work or pull the saw
backward while the blade is in motion or kick-
back may occur. Investigate and take cor rective
actions to eliminate the cause of blade binding.
c) When restarting a saw in the work piece, cen-
tre the saw blade in the kerf and check that saw
teeth are are not engaged into the material. If
saw blade is binding 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 an kick-
back.
f) Blade depth and bevel adjusting lock ing 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 pro-
truding blade may cut objects than can cause
kick back.
5.4 Specific Safety Rules for HK 132 E Circular
Saws
Lower guard function
a) Before each use, check if the retract ing blade
guard closes properly. Do not operate the saw if
the retracting blade guard does not move freely
and retract immediately. Never clamp or tie the
retracting blade guard in the open position. If the
saw is accidentally dropped, the retracting blade
guard can be bent. Pull back the retracting blade
guard with the pull-back lever and ensure that it
moves freely and does not touch the saw blade or
other parts at any cut ting angles and depths-of-cut.
b) Check the spring function of the re tracting
blade guard. If the retract ing blade guard and
the spring do not operate properly, have the
machine serviced before using. The retracting
blade guard may operate sluggish due to dam-
aged parts, gummy deposits or build-up of chips/
sawdust.
c) Only pull back the retracting blade guard manu-
ally for special cuts, such as "plunge and bevel
cuts". Pull back the retracting blade guard with
the pull-back lever and release it as soon as the
saw blade has penetrated the work. For all other
sawing jobs, the re tracting blade guard must op-
erate auto matically.
d) Do not place down the saw on a work bench or
the ground without the re tracting blade guard
covering the saw blade. An unprotected, coast-
ing saw blade will move the saw in the op posite
direction of the cut, cutting what ever is in its path.
Pay attention to the run-on period of the saw.
Riving knife function
a) Use the matching riving knife for the saw blade
being worked with. The riving knife must be wid-
er than the thick ness of the blade back, but thin-
ner than the kerf width of the saw blade.
b) Adjust the riving knife as described in the oper-
ating instructions. Incor rect width, position and
alignment can be the cause that the riving knife
does not effectively prevent kickback.
c) Always use the riving knife, except when per-
forming plunge cuts. After the plunge cut, mount
the riving knife again. The riving knife interferes
when performing plunge cuts and can lead to
kickback.
d) In order for the riving knife to be ef fective, it
must be located in the cut. For short cuts, the riv-
ing knife is ineffec tive for the prevention of kick-
back.
e) Do not operate the saw with a bent riving knife.
Even a minor malfunction can lead to sluggish re-
traction of the re tracting blade guard.
