Hilti SCM 22-A Original Operating Instructions page 10

▶ 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.
▶ Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf
causing excessive friction, blade binding and kickback.
▶ 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.
▶ Use extra caution when sawing into existing walls or other blind areas. The protruding blade may
cut objects that can cause kickback.
Lower guard function
▶ Check lower guard for proper closing before each use. Do not operate the saw if lower guard does
not move freely and close instantly. Never clamp or tie the lower guard into the open position. If
saw is accidentally dropped, 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.
▶ Check the operation of the lower guard spring. If the guard and the spring are not operating
properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
▶ Lower guard may be retracted manually only for special cuts such as "plunge cuts" and "compound
cuts". Raise lower guard by retracting handle and as soon as blade enters the material, the lower
guard must be released. For all other sawing, the lower guard should operate automatically.
▶ Always observe that the lower 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.

▶ Do not touch the clamping flange or the clamping screw while the power tool is running.
▶ Never press the drive spindle lock button while the saw blade is rotating.
▶ Never direct the power tool toward persons.
▶ Adjust the pressure applied to the saw blade and the material being cut so that the blade does not
stall, possibly causing kickback.
▶ Metal chips / cuttings are sharp and may cause injury. Keep your clothing closed so that no metal
chips or cuttings can find their way into your gloves, footwear or any other part of your clothing.
▶ Pay attention to where the metal cuttings are flying. The cuttings are hot and could cause a fire or

kinds of dust are classified as carcinogenic such as oak and beech dust, especially in conjunction with
additives for wood conditioning (chromate, wood preservative). Material containing asbestos may be
handled only by specialists. Use a dust removal system whenever possible. To achieve a high level
of dust collection, use a suitable vacuum cleaner. When indicated, wear a respirator appropriate
