Preventing Kickbacks
Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing the saw to jar, bounce or judder. 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.
This potentially damaging or dangerous problem can occur 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 workpiece causing the blade to climb out of the kerf and jump back towards the operator.
Kickback is the result of saw misuse and or incorrect operating procedures or conditions and can be avoided by taking proper precautions as
described below:
•
Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces. Position your body to either side of the
blade, but not in line with the blade.
•
If the blades are binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the
blades come to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blades are 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, centre the saw blade in the kerf and check that the saw teeth are not engaged into the material. If
the saw blade is binding, it may walk up or kickback from the workpiece as the saw is restarted.
•
Support large workpieces and panels to minimise the risk of blade pinching and kickback. Large pieces tend to sag under their own weight.
Supports should be placed under them on both sides, near the line of cut and near the edge of the panel
•
Ensure blade depth and bevel adjusting locking levers are tight and secure before making a cut. If the blade adjustment shifts while cutting it
may cause binding and result in kickback.
•
Do not use dull or damaged blades. Unsharpened or improperly set blades produce a narrow kerf causing excessive friction, blade binding
and kickback.
•
Use extra caution when making a “plunge cut” into existing walls or other blind areas. The protruding blade may cut objects that can cause
kickback.
•
Check the lower guard for proper closing before each use. Do not operate the saw if the lower guard does not move freely and close
instantly. Never clamp or tie the lower guard into the open position. If the saw is is accidentally dropped, the lower guard may be bent. With
the saw disconnected from the power supply, check the lower guard and make sure it moves freely and does not touch the blade or any
other part, in all angles and depths of cut. If an issue is detected or the guard does not move freely the guard or blade may be damaged or
fitted incorrectly. Repair before reusing the saw.
•
Check the operation of the lower guard spring. If the guard and the spring are not operating properly, they must be serviced before use. The
lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
•
The lower guard may be retracted manually only for special cuts such as “plunge cuts” and “compound cuts.” Raise the lower guard 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 a bench or the 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.
UNPACKING
Upon receipt of the equipment, ensure all components are present and have remained undamaged in transit. Retain the packing materials and
packaging in case future transportation of the equipment is necessary.
We recommend that the packaging is kept, at least within the period of the warranty guarantee. Store the user manual in a safe location for future
reference.
PLEASE NOTE:
This packaging contains sharp objects. Take care when unpacking. The saw is also quite heavy and may require two individuals
to safely remove from the cardboard packaging.
