Experience is very important when running the 50 Handheld saw. A skilled worker is highly recommended. Always do an inspection of the saw before using it. Insure all guards are secure, undamaged, and properly installed and that the spring loaded lower blade guard swings open and closes freely with- out binding.

WARNING

Do not operate the saw unless all guards, safety equipment and the engine kill switch are in place and operational!

Position the power cord clear of the intended saw cut. Do not wrap the cord around your arm or wrist. Check for proper specification of blade and that the skid plate operates properly. Check that the blade and skid plate are in good condition. Make sure the work site is clean, well lit and hazard free.

Husqvarna Soff-Cut recommends the use of a vacuum system when using the 50 Handheld saw. The integrated dust extraction port (M) is designed for easy attachment of standard 1 1/2 (38 mm) vacuum hose. The vacuum system allows the saw to function at its peak efficiency, making for a high quality saw joint with the additional benefit of little or no cleanup required (of the saw and/ or saw joints) and marked reduction in breathable airborne dust.

The saw is factory set to full depth-of-cut, typically 1” (25.4

mm)with a brand new blade. If a shallower depth of cut is desired, such as for architectural scoring and decorative ap- plication, adjust blade depth by turning the depth adjust thumb screw (D) approximately one full turn counter-clockwise. Slide the depth adjust arm (E) to the desired depth using the depth indicator label (B). Tighten the depth adjust thumb screw (D) by hand to lock the depth arm in place. Rotate the front guide

(A) down to the forward position.

Line up the saw with the cut line using the “S” notch (F) on the lower guard (N) and the triangle pointer at the rear of the lower blade guard. Make sure the skid plate lies flat on the concrete with the rear wheel (J). Flip the lock-off button and simultane- ously squeeze the paddle switch (L) to turn “ON” the saw

NOTE: Pressure must be maintained continuously on the paddle switch to keep electric motor running.

Rotate the saw down slowly to plunge and lower the blade in the concrete. Push the saw forward to cut, keeping the front guide wheel on the cut line. Do not force the saw; let the dia- mond blade to work.

When approaching a wall, raise the front guide and use the “S” notch and the triangle guide at the rear of the blade guard to cut the last few inches.

At the end of the cut, rotate the saw up to raise the blade out of the cut, without lifting the skid plate off the concrete. The skid plate must remain flat on the concrete until the blade is completely out of the concrete. NOTE: Do not release the paddle switch or switch off the saw while the blade is in the concrete; doing so will cause the saw cut to ravel and spall. Do not walk on the joints or transport equipment across the joints until the concrete fully hardens.

WARNING

Do not leave the saw unattended while the engine is running! Always secure the saw from movement while unattended.

WARNING

Before each use, carefully inspect the 50 Handheld for any damage to any of its parts and components. Under no circumstance should the 50 Handheld or any of its attachments be operated if you find dam- age or are suspicious that something appears to be damaged.

GENERATORS AND EXTENSION CORDS

If an extension cord is necessary, a cord of adequate size conductors that is capable of carrying the current necessary for your tool must be used. Replace damaged or worn out cords immediately. Refer to the chart for the correct size to use. If in doubt, use the next heavier gauge. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. When using a generator, Husqvarna Soff-Cut recommends a generator with minimum rating of 2800 Watts and a 20 Amps circuit breaker.
