f)When ripping always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding.
g)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.
h)Never use damaged or incorrect blade washers or bolts. The blade washers and bolts were specially designed for your saw, for optimum performance and safety of operation.
2.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 mis- aligned 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 operator.
KICKBACK is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precau- tions as given below:
work or pull the saw backward while the blade is in motion or KICKBACK may occur. Investigate and take cor- rective actions to eliminate the cause of blade binding.
c) | When restarting a saw in the work- |
| piece, center the saw blade in the |
| kerf and check that saw 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. |
d) Support large panels to minimize | |
| the risk of blade pinching and KICK- |
| BACK. 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 blade. |
| Unsharpened or improperly set blades |
| produce narrow kerf causing excessive |
| friction, blade binding and KICKBACK. |
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 protruding |
| blade may cut objects that can cause |
| KICKBACK. |
3. | 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 |
5.Lower guard should be retracted manually only for special cuts such as "Plunge Cuts" and "Compound Cuts". Raise lower guard by retract- ing handle and as soon as blade enters the material, the lower guard must be released. For all other saw- ing, the lower guard should operate automatically.
6.Always observe that the lower guard is covering the blade before plac- ing 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.
7.Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free replacement.
8.WARNING: Some dust created by power sanding, sawing, grinding, drill- ing, and other construction activities contains chemicals known to cause cancer, birth defects or other reproduc- tive harm. Some examples of these chemicals are:
•lead from
•crystalline silica from bricks and cement and other masonry products, and
•arsenic and chromium from chemically- treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ven- tilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
9.Do not touch material after it has been cut. Cut material may be very hot.
10.Do not use cutting oil. The use of cut- ting oil may cause a fire.
11.Do not use tool near flammable mate- rial. Sparks may cause fire.
12.Do not cut workpieces covered or stained with gas, oil, solvents, thin- ners, etc. Exposure to these materials may damage the transparent guard.
13.Do not remove the transparent front guard. If the transparent front guard is damaged or missing, return tool to authorized service station for replace- ment.
14.Do not start the blade when in contact with workpiece. Wait for blade to reach full speed before beginning cut.
a)Maintain a firm grip with both hands on the saw and position your arms to resist KICKBACK forces. Posi- tion your body to either side of the blade, but not in line with the blade. KICKBACK could cause the saw to jump backwards, but kickback 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 attempt to remove the saw from the
or tie the lower guard into the open po- |
sition. 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. |
4. Check the operation and condition |
of the lower guard spring. If the |
guard and the spring are not operat- |
ing properly, they must be serviced |
before use. Lower guard may operate |
sluggishly due to damaged parts, gum- |
my deposits, or a buildup of debris. |
