Operator’s Manual GLCS2055A
CAUTION:
Blades coast after turn off. Wait until blade stops before grasping cut material.
•
Check lower guard for proper closing before each use
.
Do not operate 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 Lever and
make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut. To
check lower guard, open lower guard by hand, then release and watch guard closure. Also check to see that
Retracting Lever does not touch tool housing. Leaving blade exposed is VeRY DANGeRouS and can lead to
serious personal injury.
•
Check the operation and condition 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 buildup of debris.
•
Lower guard should be retracted manually only for special cuts
such as “Pocket
Cuts” and “Compound Cuts.” Raise lower guard by retracting the lever. As soon as blade enters the material,
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.
•
NEVEr hold piece being cut in your hands or across your leg
. It is important to
support the work properly to minimize body exposure, blade binding, or loss of control.
•
When ripping, always use a rip fence or straight edge guide
. This improves the
accuracy of cut and reduces the chance for blade binding.
•
Always use blades with correct size
and shape (diamond vs. round) arbor holes. Blades that
do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
•
Never use damaged or incorrect blade washers or bolts.
The blade washers and
bolt were specially designed for your saw, for optimum performance and safety of operation.

Causes and operator prevention of Kickback:
Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled saw to lift
up and out of the workpiece toward the operator.
* When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor reaction
drives the unit rapidly back toward the operator.
* If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into
the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator.
* Kickback is the result of tool misuse and/or incorrect operating procedures of conditions and can be
avoided by taking proper precautions as given below:
> Maintain a firm grip on the saw and position your body and arm in a way that allows you to resist
KICKBACK forces. KICKBACK forces can be controlled by the operator, if proper precautions are taken.
> 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.
> When restarting a saw in the workpiece, center the saw blade in the kerf and check that teeth 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.
> Support large panels to minimize 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 will cause binding and KICKBACK.
> use extra caution when making a “Pocket Cut” into existing walls or other blind areas. The protruding
blade may cut objects that can cause KICKBACK.
