MAINTENANCE
1.
DANGER: Keep hands away from cutting area and the blades. Keep your second hand on auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blades.
2.Do not reach underneath the workpiece.
The guard cannot protect you from the blades below the workpiece.
3.Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blades’ teeth should be visible below the workpiece.
4.Never hold piece being cut in your hands or across your leg. Secure the workpiece to a stable platform. It is important to support the work properly to minimize body exposure, blade binding, or loss of control.
5.Hold power tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a ″live″ wire will also make exposed metal parts of the power tool ″live″ and shock the operator.
6.When ripping always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding.
7.Always use blades with correct size and shape (diamond versus round) of arbor holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
8.Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.
9.Causes and Operator Prevention of Kickback:
•Kickback is a sudden reaction to a pinched, bound or misaligned saw blades, causing an uncontrolled saw to lift up and out of the workpiece toward the operator;
•When the blades are pinched or bound tightly by the kerf closing down, the blades stall and the motor reaction drives the unit rapidly back toward the operator;
•If the blades become twisted or misaligned in the cut, the teeth at the back edge of the blades can dig into the top surface of the wood causing the blades to climb out of the kerf and jump back toward 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 given below:
a.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 blades, but not in line with the blades.
Kickback could cause the saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are taken.
b.When 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.
c.When restarting a saw in the workpiece, center the saw blades in the kerf and check that saw teeth are not engaged into the material. If saw blades are binding, they may walk up or kickback from the workpiece as the saw is restarted.
d.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.
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 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 protruding blades may cut objects that can cause kickback.
