WOOD CUTTING (FIGURE H)

Before cutting any type of wood, be sure the work piece is firmly anchored or clamped to prevent slipping.

Place blade and shoe lightly against work to be cut.

Switch on saw motor before applying pressure.

Always hold saw firmly with both hands while cutting. Whenever possible, the shoe must be held firmly against the material being cut. This will prevent the saw from jumping or vibrating and minimize blade breakage.

METAL CUTTING (FIGURE I)

Use a finer blade for ferrous metals and a coarse blade for non-ferrous materials.

In thin gauge sheet metals it is best to clamp wood to the underside of the sheet. This will ensure a clean cut without excess vibration or tearing of metal.

Avoid forcing cutting blade as this reduces blade life and causes costly blade breakage.

NOTE: You should spread a thin film of oil or other coolant along the line ahead of the saw cut for easier operation and longer blade life. For cutting aluminum, kerosene is preferred.

POCKET CUTTING - WOOD ONLY (FIGURE J)

Measure the surface area to be cut and mark clearly with a pencil, chalk or scriber.

Insert blade in blade clamp and tighten blade clamp securely.

Tip the saw backward until the back edge of the shoe is resting on the work surface.

Switch motor on, permitting blade to attain maximum speed.

Grip handle steadily and begin a slow, deliberate upward swing with the handle of the saw.

The blade will begin to feed into material. Always be sure blade is completely through material before continuing with pocket cut.

NOTE: In areas where blade visibility is limited, use the edge of the shoe as a guide.

PROJECT TIPS

Cut only with sharp blades; they cut cleaner, faster and put less strain on the motor while cutting.

When cutting, always ensure that the shoe is resting against the workpiece. This will improve operator control and minimize vibration.

For longer blade life, use bi-metal blades. These utilize a carbon steel back welded to high speed steel teeth making the blade more flexible and less prone to breaking.

MAINTENANCE

REMOVE BATTERY FROM SAW WHEN PERFORMING ANY CLEANING OR OTHER MAINTENANCE. WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS.

Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to various types of commercial solvents and may be damaged by their use. Use only mild soap and damp cloth to clean the tool. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

When electric tools are used on fiberglass boats, sports cars, drywall etc.,they are subject to accelerated wear and possible premature failure, as the fiberglass chips and grindings
