RULES FOR SAFE OPERATION

KNOW THE TOOL

To operate this tool safely, carefully read this operating manual and all the labels affixed to the Compound Mitre Saw before using it, and follow all instructions contained therein. Retain this manual for future reference.

MPORTANT

This tool should only be serviced by a qualified service technician.

READ ALL INSTRUCTIONS THOROUGHLY

SAFETY PRECAUTIONS FOR LASERS

This Mitre Saw has a built-in laser light. The laser is ClassIIlA and emits output power of a maximum 2.5mW and 635-650nm wavelengths. These lasers do not normally present an optical hazard. However, DO NOT stare at the beam, as this can cause flash blindness.

CAUTION: The following label is on the tool. It indicates the location from which the saw emits the laser light. Be aware of the laser-light location when using. Always make sure that any bystanders in the vicinity of use are made aware of the dangers of looking directly into the laser.

Do not

remove or deface any product labels. Removing product labels increases the risk of exposure to laser radiation.

The laser beam can be harmful to the eyes. Always avoid direct eye exposure.

Do not look directly into the laser-beam-output aperture during operation.

Do not project the laser beam directly into the eyes of others.

Turn the laser on only when making cuts. The laser on the Mitre Saw is not a toy.

Always keep it out of the reach of children. The laser light emitted from this device should never be directed toward any person for any reason.

Be sure that the laser beam is aimed at a work piece (such as wood or a roughcoated surface) that does not have a reflective surface.

Do not use on materials, such as sheet steel, that have shiny, reflective surfaces.

The reflective surface could reflect the beam back at the operator. Be aware that laser light reflected off of a mirror or any other reflective surfaces can also be dangerous.

Always

turn the laser beam off when it is not in use. Leaving the tool on increases the risk of someone inadvertently staring into the laser's beam.

CAUTION: Always follow the instructions contained in this manual when using this laser. Use of this feature in any manner other than which is directed in this manual may result in a hazardous radiation exposure.

Always wear laser-protective eyewear when working on or near reflective surfaces

GENERAL SAFETY PRECAUTIONS

Read and become familiar with the entire Operating Manual.

Learn the tool’s application, limitations, and possible hazards.

Keep the guard in place and in working order.

Remove all adjusting tools before turning tools on. Form the habit of checking to see that keys and adjusting wrenches are removed from the tool before turning the tool ON.

Keep the work area clean. Cluttered areas and benches invite accidents.

Do not use the tool in wet locations. Do not use power tools in damp locations or expose them to rain or snow.

Keep the work area well lit.

Keep children away. All visitors & bystanders should be kept a safe distance from the work area.

Make the workshop childproof with padlocks, master switches, or by removing starter keys.

Do not force the tool. The tool will do the job better and more safely at its designed rate.

Only use the correct tool. Do not force the tool or an attachment to do a job that it was not designed to perform.

Use proper extension cords. Make sure that extension cords are in good condition.

When using an extension cord, be sure to use a cord heavy enough to carry the drawn current needed by the Compound Mitre Saw. An undersized cord will result in a drop in line voltage and in loss of power, which will cause the tool to overheat. The table on Page 5 shows the correct size to use, depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge: the smaller the gauge number, the heavier the cord.

Wear proper apparel. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewellery that may get caught in moving parts. Non-slip footwear is recommended. Wear a protective hair covering to contain long hair

Wear a facemask or a dust mask. Sawing operations produce dust.

Secure the work. Use clamps or a vise to hold the work; it is safer than using the hand/body and it allows both hands to operate the Compound Mitre Saw.

Disconnect tools before servicing the tool and when changing accessories, such as blades, bits, and cutters.

Reduce the risk of the tool unintentionally starting.

Make sure that the switch is in the OFF position before plugging in the tool.

Only use recommended accessories. Consult this Operating Manual for recommended accessories. The use of improper accessories may cause risk of injury to the operator or to others.

Never stand on the tool.

Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted.

WARNING: The operation of any tool can result in foreign objects being propelled into the eyes, which could result in severe eye damage. When operating a power tool, always wear safety goggles or safety glasses with side shields, or a fullface shield, if necessary.

Check for damaged parts. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect the operation of the tool. A guard or other part that is damaged should be properly repaired or replaced.

Never leave the tool unattended while the power is “on.” Turn the power “off.” Do not leave the tool until the blade has come to a complete stop and the Mitre Saw has been unplugged.

Do not over-reach. Keep proper footing and balance at all times.

Maintain tools with care. Keep tools sharp and clean for optimum performance.

Follow instructions for lubricating and changing accessories.

CAUTION: Do not attempt to operate this tool until having thoroughly read all instructions, safety rules, and warnings. Failure to comply can result in fire, electric shock, or serious personal injury. Retain the Operating Manual for future reference and review it frequently.

WARNING: Dust generated from certain materials can be hazardous to one’s health. Always operate the saw in a well-ventilated area, and provide for proper dust removal.

ELECTRICAL SAFETY

Ground instruction: In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet, have a proper outlet installed by a qualified electrician.

Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool’s plug.

Permanently connected tools: This tool should be connected to a grounded metal permanent wiring system or to a system having an equipment-grounding conductor.

GUIDELINES FOR EXTENSION CORDS

Use a proper extension cord . Make sure that extension cords are in good condition. When using an extension cord, be sure to use a cord heavy enough to carry the drawn current needed by the Compound Mitre Saw. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. The table below shows the correct size to use, depending on the cord length and nameplate ampere rating. If in doubt, use the next heavier gauge: the smaller the gauge number, the heavier the cord.

Be sure extension cords are properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it.

Protect extension cords from sharp objects, excessive heat, and damp or wet areas.

Use a separate electrical circuit for power tools. This circuit must not be less than

#6 wire and should be protected with a time-delay fuse. Before connecting the tool to the power line, make sure the switch is in the OFF position and the electric current is rated the same as the current stamped on the motor nameplate; running at a lower voltage will damage the motor.

Always hold the work firmly against the fence and table. Do not perform any operation free hand; use a clamp or vise whenever possible

Keep hands out of the path of the saw blade. If the work piece causes the hands to be within the “no hands” zone (3’’ (7.6 cm) from the blade), the work piece should be clamped in place before making the cut.

Be sure that the blade is sharp, runs freely, and is free of vibration.

6

Allow the motor to come up to full speed before starting a cut.

Keep the motor’s air slots clean and free of chips or dust.

Always make sure that all adjusting knobs are tightened before cutting, even if the table is positioned in one of the positive stops.

Be sure that both the blade and the flange are clean and the arbour bolt is tightened securely.

Use only flanges specified for this saw.

Never use blades larger or smaller in diameter than 12 inches (30.5 cm).

Never apply lubricants to the blade while it is running.

Always check the blade for cracks or damage before operation. Replace a cracked or damaged blade before further use.

Never use blades recommended for operation at less than 4500 RPM.

Use the blade guards at all times.

Always keep the blade guards in place.

Never reach around the saw blade.

Make sure that the blade is not contacting the work piece before the ON/OFF switch is turned ON.

IMPORTANT: After completing the cut, release the power switch and wait for the blade to stop before returning the saw to the raised position.

Make sure that the blade has come to a complete stop before removing or securing the work piece, changing the work-piece angle, or changing the angle of the blade.

Selection of Desired Angle

Follow the steps in “MITRE ADJUSTMENT” and “BEVEL ADJUSTMENT”

WARNING: The throat plate (see Fig.1, point 12) is factory-cut only for a 0º bevel cut; the first cut made with the tool in the 45° bevel position will create a slot on throat plate.

WARNING: Always make sure that the spindle-lock button is released, so that the blade will rotate freely.

WARNING:

Make sure that the stop latch is loose and that the saw head moves freely up and down. Ensure that all clamps and locks are tight, in place, and that there is no excessive movement of Mitre-Saw parts.

Selection of work piece

Be cautious with pitchy, knotty, wet, or warped work pieces. These materials are likely to create pinching conditions. Work pieces that bow and pinch may result in the saw blade kicking back.

Before cutting, inspect for and remove any nails from the work piece.

This tool is not recommended for cutting ferrous metals, such as iron and steel. Cut non-ferrous metals only if under the supervision of an experienced person.

14

Support the work piece

WARNING: Never use the help of another person as a substitute for a table extension, as support for a work piece that is longer or wider than the basic mitre table. Never have another person help feed, support, or pull the work piece instead of using table extensions.

Use the fence.

Align the work piece flush against the fence. This

Fig. 8 will help to eliminate the tendency of the blade teeth to bind. The fence can be used to support mitre, bevel, and compound cuts.

Work-piece clamp

saw arm to make sure that no problems will occur when the cut is made.

11. Hold the saw handle and use the index finger to turn on the laser switch by pushing it forward.

12. To turn on the saw, push the safety-lock button in with the thumb while squeezing the On/Off trigger switch located under the handle (Fig.1-1 and Fig.1-3). Allow several seconds for the blade to reach maximum speed.

13. Slowly lower the blade into and through the work piece.

14. Release the safety lock and the trigger switch, and turn off the laser switch. Allow the saw blade to stop rotating before raising the blade out of the work piece

CAUTION: Always perform a “dry run” cut to determine if the operation being attempted is possible before power is applied to Mitre Saw.

COMPOUND MITRE CUTTING

(Fig. 14)

A compound mitre cut is a cut made using a mitre angle and a bevel angle at the same time. This type of cut is used for decorative mouldings, picture frames, and other fine joinery.

To make this type of cut, the mitre table must be rotated to the correct mitre angle and the saw arm must be tilted to the correct bevel angle.

Fig. 14

Always take special care when making compound mitre cuts, due to the interaction of the two angle settings.

Adjustments of mitre and bevel settings are dependent on one another. Each time the mitre setting is adjusted, the effect of the bevel setting also changes. Each time the bevel setting is adjusted, the effect of the mitre setting is changed.

It may take several settings to obtain the desired cut. The first angle setting should be checked after setting the second angle, since adjusting the second angle affects the first.

Once the two correct settings for a particular cut have been obtained, always make a test cut in scrap material before making a finish cut in good material.

To Make a Compound Mitre Cut with the Mitre Saw

1. Unplug the saw.

WARNING: Failure to unplug the saw could result in accidental starting, causing serious injury.

2. Pull out the locking pin to release the saw arm.

3. Loosen the mitre-lock knob to loosen the mitre table.

4. Hold the base of the saw arm firmly and use it to rotate the mitre table while holding the saw base steady.

5. The 0

°

, 15

°

, 22.5

°

, 31.6°, and 45

°,

left and right settings are quickly identifiable with the stops at the angle settings.

6. When the desired mitre-table setting is achieved, tighten the mitre-lock.

19

WARNING: To avoid serious personal injury, always securely tighten the mitre-lock lever before making a cut. Failure to do so could result in movement of the control arm or mitre table while making a cut.

7. To set the bevel angle, loosen the bevel-lock knob (Fig. 1-22) by turning the knob counter clockwise.

8. Tilt the saw arm to the desired bevel angle, as shown on the bevel scale. Bevel angles can be set from 0

° to 45

° left bevel.

9. Once the saw arm has been set at the desired angle, securely tighten the bevellock knob.

10. Place the work piece flat on the mitre table with one edge securely against the fence. If the board is warped, place the convex side against the fence. If the concave edge of the board is against the fence, the board could collapse on the blade at the end of the cut and jam the blade (Figs. 15 and 16).

11. Align the red laser line to touch the right edge of the pencil line on the work piece.

12. Use the hold-down clamp to secure the work piece against the saw table and fence.

13. When cutting long work pieces, support the opposite end of the work piece with a roller stand or with another work surface that is level with the saw table.

CAUTION: NEVER use another person as an additional support for a work piece that is longer or wider than the basic saw table, or to help feed, support, or pull the work piece.

WARNING: To avoid serious personal injury, always keep hands outside the

“no hands zone”, as marked on the saw table, which is at least 3 inches (7.6 cm) from the blade. Also, never perform any cutting operation “freehand” (i.e. without holding the work piece against the fence); the blade could grab the work piece, causing it to slip and twist.

14. Make sure that there will be no obstructions to interfere with making the cut.

15. Hold the saw handle and use the index finger to turn on the laser switch by pushing it forward.

16. To turn on the saw, push the safety-lock button in with the thumb while squeezing the On/Off trigger switch located under the handle (Fig.1-1 and 1-3). Allow several seconds for the blade to reach maximum speed.

17. Slowly lower the blade into and through the work piece.

18. Release the safety lock and trigger switch, and turn off the laser switch. Allow the saw blade to stop rotating before raising the blade out of the work piece

20

CUTTING WARPED MATERIAL (Fig. 15 and 16)

WARNING: To avoid kickback and to avoid serious personal injury never position the concave side of bowed or warped material against the fence.

When cutting warped material, be certain that the material to be cut is positioned on the mitre table with the convex side against the fence, as shown (Fig. 15).

If the warped material is positioned the wrong way, (Fig. 16), it will pinch the blade near the end of the cut.

Fig. 15 Fig. 16

MAINTENANCE

Before cleaning or performing any maintenance, make sure that the Mitre Saw has been disconnected from the power supply. Keep all ventilation openings clean. Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use a clean cloth to remove dirt, oil and grease.

WARNING: Do not allow improper materials, such as brake fluids, gasoline, petroleum-based products, penetrating oil, etc., to come in contact with plastic parts as improper materials contain chemicals that can damage, weaken or destroy plastic.

WARNING:

To ensure safety and reliability, all repairs should be performed by a qualified service technician.
