    What is kickback?

    The term kickback is used to describe the sudden reaction that causes the Quickie Saw and

    cutting blade to be thrown from an object when the upper quadrant of the blade touches anobject.

    Warning: Tool kickback can happen very suddenly and violently, kicking the Quickie Saw

    and cutting blade back at the user. This can cause very serious or even fatal injuries.

    1. It is vital that you understand what causes kickback and that you can avoid it by operatingthe saw properly and carefully at all times.

    1. When cutting an object from the bottom to avoid pinch points it is essential that wemaintain a controlled manageable speed when we are using the portion of the blade

    closest to the upper quadrant.

    1. Always hold the saw in a firm grip with both hands. Hold it so that the thumbs andfingers grip round the handles.

    1. Keep a good balance and firm foothold.

    1. Always cut at an appropriate speed for the material and type of cut you are making.

    Stand at a comfortable distance from the work piece,(not reaching and not to close to

    your body).

    1. Take extreme care when inserting the blade in an existing cut. (Appropriate speed) Never

    wedge or jam the running blade into the cut.

    1. NEVER cut above shoulder height.

    1. Be alert to the movement of the work piece or anything else which might cause the cut to

    close and pinch the blade

    Pinching/Rotation

    1. If the cut is pressed together this can lead to jamming, the machine can be pulled down

    suddenly with a very powerful jerk.

    1. To avoid pinching support the work piece in such a way that the cut remains open during

    the cutting operation and when the cut is finished.

    utting Technique1. When starting a cut, with the throttle at a slow speed move the blade slowly forward and

    backwards in small increments to achieve a small contact area between the blade and the

    material to be cut.

    1. Once the saw is making a distinct cut and not bouncing bring the throttle up toappropriate cutting speed (cutting and not burning, allow saw to do the work).

    1. Feed down the machine in line with the blade. Pressure from the side can damage the

    blade and is very dangerous.

    1. The guard for the cutting equipment should be adjusted so that the rear section is flush

    with the work piece. Debris and sparks from the material being cut are then collected up

    by the guard and directed away from the user.

    Warning: The blade can become out-of-round and vibrate if excessive force

    pressure is used on the saw, if the saw begins to vibrate, stop the saw immediately

    and take the blade out of service.

    1. Operating a Quickie Saw must be done with firm solid footing, using any type of make

    shift scaffolding is grounds for dismissal.

    1. Keep a firm, but steady hold on the saw, applying the correct pressure, the "right touch".

    1. You can get tired, without realizing it, and lose control of the saw; so be sure to take

    periodic breaks.

    1. Hand and wrist stretches should be performed at regular intervals when cutting for

    lengthy periods of time.

    Sawing/Cutting Procedure

    1. Check Blade for Condition and tightness (mark blade and retaining nut with marker) thiswill allow you to quickly ensure blade has not moved during operation.

    1. Check abrasive blades for damages (cracks, chips, gouges) or worn out.

    1. Warning: Never use any blade with any Damage.

    If Saw is damaged of defective, take it out of service and place red tag on it, and let

    foreman know so it can be repaired.

    How to Cut Asphalt Paving

    Instructions

    1.o 1

    Measure the section of asphalt to be cut and mark it with a construction crayon.

    Once the marks are in place, connect them using a chalkline filled with red chalk.You may need to double-snap the lines so that they remain visible during cutting.

    o 2

    Prepare the masonry cutting saw by connecting a water hose to the hose

    connection located on the rear of the saw. This water connection will provide

    water to the blade of the saw, keeping the amount of sawdust to a minimum. Thissaw resembles a large chainsaw but has a round blade attached rather than a

    chain. You can rent this saw at any tool rental store, and it can be operated using

    two-cycle oil and gas. This tool requires a bit of strength to operate, and it shouldnever be used without gloves, eye goggles and a dust mask.

    o 3

    Cut into the asphalt slowly, allowing the saw blade to cut gently into the asphalt.

    The saw will pump water up to the blade and dampen the amount of dust that isgenerated. Don't try to cut too much of the asphalt at once. Cut about half of the

    depth of the asphalt on the first pass, then make a second pass to finish cuttingcompletely through the material.

    o 4

    Remove the asphalt paving with a pick. Break the asphalt into smaller pieces

    using the flat end of the pick, and remove these pieces with a shovel. This method

    will allow you to complete the job without sustaining overuse injuries from heavyloads. If the asphalt is relatively thick and you have a hard time breaking it up

    with a pick, use a jack hammer to break it into smaller pieces. Cut cross-hatches

    into the asphalt using the masonry saw. These hatches will help weaken the

    asphalt, causing it to crumble.
