Circular saw safety warnings Cutting procedures
-
DANGER: Keep hands away from cutting area and the blade. Keep your second hand on auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
-
Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.
-
Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below the workpiece.
-
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.
-
Hold the power tool by insulated gripping surfaces only, 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 could give the operator an electric shock. -
When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding.
-
Always use blades with correct size and shape (diamond versus round) of arbour 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 bolt. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation. Kickback causes and related warnings
-
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 saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given 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. Kickback could cause the saw to jump backward, but kickback forces can be controlled by the operator, if proper precautions are taken. -
When the 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 those saw teeth are not engaged into the material. If saw blade is binding, it may walk up or kick back 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 may cause binding and kickback.
-
15. Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.
-
ALWAYS hold the tool firmly with both hands. NEVER place your hand or fingers behind the saw. If kickback occurs, the saw could easily jump backwards Over your hand, leading to serious personal injury.
-
Never force the saw. Push the saw forward at a speed so that the blade cuts without slowing. Forcing the saw can cause uneven cuts, loss of accuracy, and p0ssible 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.
-
To check lower guard, open lower guard by hand, then release and watch guard closure.
Also check to see that retracting handle does not touch tool housing. Leaving blade exposed is VERY DANGEROUS and can lead to serious personal injury.
Additional safety warnings
-
Use extra caution when cutting damp wood, pressure-treated lumber, or wood containing knots. Maintain smooth advancement of tool without decrease in blade speed to avoid overheating the blade tips.
-
Do not attempt to remove cut material when blade is moving. Wait until the blade stops before grasping cut material. Blades coast after turn off.
-
Avoid cutting nails. Inspect for and remove all nails from lumber before cutting.
-
Place the wider portion of the saw base on that part of the workpiece which is solidly supported, not on the section that will fall off when the cut is made.
-
DO NOT TRY TO HOLD SHORT PIECES BY HAND!
-
Before setting the tool down after completing a cut, be sure that the lower guard has closed and the blade has come to a complete stop.
-
Never attempt to saw with the circular saw held upside down in a vise. This is extremely dangerous and can lead to serious accidents.
-
Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.
-
Do not stop the blades by lateral pressure on the saw blade.
-
Always use blades recommended in this manual.
Do not use any abrasive wheels. -
Keep blade sharp and clean. Gum and wood pitch hardened on blades slows saw and increases the potential for kickback. Keep the blade clean by first removing it from tool, then cleaning it with gum and pitch remover, hot water or kerosene. Never use gasoline.
-
Wear a dust mask and hearing protection when use the tool.

Functional description
CAUTION: Always be sure that the tool is switched off and unplugged
before adjusting or checking function on the tool.
Adjusting depth of cut (Fig. 1)
CAUTION: After adjusting the depth of cut, always tighten the lever.
Loosen the lever on the depth guide and move the base up or down. At the
desired depth of cut, secure the base by tightening the lever.
For cleaner, safer cuts, set cut depth so that no more than one blade tooth
projects below workpiece. Using proper cut depth helps to reduce potential for
dangerous KICKBACKS which can cause personal injury.
Bevel cutting (Fig. 2) Loosen two clamping screws on the bevel plates on the front and back of the base. Set for the desired angle (0-45°) by tilting accordingly, then tighten the clamping screws securely.
Sighting (Fig. 3) For straight cuts, align the A position on the front of the base with your cutting line. For 450 bevel cuts, align the B position with it.
Switch action (Fig. 4) CAUTION: Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.
For tool with lock button
To start the tool, simply pull the switch trigger. Release the switch trigger
to stop.
For continuous operation, pull the switch trigger and push in the lock button
and then release the switch trigger.
To stop the tool from the locked position, pull the switch trigger fully, then
release it.
For tool with a lock-off button
To prevent the switch trigger from being accidentally pulled, a lock-off
button is provided. To start the tool, push in the lock-off button and pull
the switch trigger.
Release the switch trigger to stop.
For tool without lock button and lock-off button
To start the tool, simply pull the switch trigger. Release the switch trigger
to stop.
Assembly
CAUTION: Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.
Removing or installing saw blade (Fig. 5 & 6) **CAUTION:** Be sure the
blade is installed with teeth pointing up at the front of the tool.
Use only the Bormann wrench to install or remove the blade.
To remove the blade, press the shaft lock so that the blade cannot revolve and
use the hex wrench to loosen the hex bolt counter-clockwise. Then remove the
hex bolt, outer flange and blade.
For tool with the inner flange for a 15.88mm hole diameter saw blade (Fig.
7) Mount the inner flange with its recessed side facing outward onto the
mounting shaft and then place saw blade, outer flange and hex bolt.
BE SURE TO TIGHTEN THE HEX BOLT CLOCKwISE SECURELY.
For tool with the inner flange for a other than 15.88 mm hole-diameter saw
blade (Fig. 8) The inner flange has a certain diameter protrusion on one
side of it and a different diameter protrusion on the other side. Choose a
correct side on which protrusion fits into the saw blade hole perfectly.
Next, mount the inner flange onto the mounting shaft so that the correct side
of protrusion on the inner flange faces outward and then place saw blade and
outer flange.
BE SURE TO TIGHTEN THE HEX BOLT CLOCKWISE SECURELY.
CAUTION: Make sure that the protrusion “a” on the inner flange that is
positioned outside fits into the saw blade hole “a” perfectly. Mounting the
blade on the wrong side can result in dangerous vibrations.
Hex wrench storage (Fig. 9) When not in use, store the hex wrench as shown in the figure to keep it from being lost.
Operation
CAUTION: Be sure to move the tool forward in a straight line gently.
Forcing or twisting the tool will result in overheating the motor and
dangerous kickback, possibly causing severe injury.
Always use a front grip and rear handle and firmly hold the tool by both the
front grip and rear handle during operations. The tool is provided with both a
front grip and rear handle. If both hands are holding the saw, they cannot be
cut by the blade. Set the base on the workpiece to be cut without the blade
making any contact. Then turn the tool on and wait until the blade attains
full speed. Now simply move the tool forward over the workpiece surface,
keeping it flat and advancing smoothly until the sawing is completed.
To get clean cuts, keep your sawing line straight and your speed of advance
uniform. If the cut fails to properly follow your intended cut line, do not
attempt to turn or force the tool back to the cut line. Doing so may bind the
blade and lead to dangerous kickback and possible serious injury. Release
switch, wait for blade to stop and then withdraw tool. Realign tool on a new
cut line, and start cut again. Attempt to avoid positioning which exposes the
operator to chips and wood dust being ejected from saw.
Use eye protection to help avoid injury.
Rip fence (guide rule) (not included with all models) (Fig. 11) The handy rip fence allows you to do extra-accurate straight cuts. Simply slide the rip fence up snugly against the side of the workpiece and secure it in position with the screw on the front of the base. It also makes repeated cuts of uniform width possible.
Maintenance
CAUTION:
Always be sure that the tool is switched off and unplugged before attempting
to perform inspection or maintenance.
Never use gasoline, benzene, thinner, alcohol or the like. Discoloration,
deformation or cracks may resut.
Replacing carbon brushes (Fig. 12 & 13) Remove and check the carbon
brushes regularly.
Replace when they wear down to the limit mark. Keep the carbon brushes clean
and free to slip in the holders.
Both carbon brushes should be replaced at the same time. Use only identical
carbon brushes.
Use a screwdriver to remove the brush holder caps. Take out the worn carbon
brushes, insert the new ones and secure the brush holder caps.
