USING THE SAW

STARTING WORK

Consult the Blade Selector Charts for the blade best suited for the material to be cut. For greatest economy, use the shortest blade suitable for the thickness of the material to be cut.

Be sure the material to be cut is rigid. Small work pieces should be securely clamped in a bench vise or to a work table. As the work progresses in scroll or curved cut-out pieces, the material may be adjusted to accommodate the movement of the saw. If the work is large enough, it may be hand held across saw horses. The saw cuts freely with only slight feed pressure. Forcing the saw will not make it cut faster.

SAWING WOOD

The saw is used much the same as a hand saw in that it is moved toward the operator during the cutting operation. However, since the blade cuts on the up-stroke instead of the down-stroke as in the case of the hand saw, the good or finish side of the work should face down during the cut- ting operation.

PLUNGE CUTS

The saw can be used for plunge cutting wood, plywood, wallboard, and plastic materials. DO NOT attempt to plunge cut metal.

Clearly mark line of cut on the work. Grasp front housing with one hand and rear handle with the other hand. To start cut, rest saw on shoe bracket, align blade with the marked line of cut, (blade NOT touching work), as shown in Fig. 4. Start saw. Using bracket as a pivot point, roll saw forward by raising rear handle, as shown in Fig. 5. When blade has cut through the work, continue raising the rear handle until saw is perpendicular to the work surface. Keep saw in this position and move blade along line of cut.

SAWING METAL

When cutting angle, H-beam, I-beam, channel, etc., start the cut on the surface where the greatest number of teeth will contact the work. To make a pocket cut, drill a starting hole first. To extend blade life, cutting oil can be applied to the work surface along the line of the cut.

MAINTENANCE

KEEP TOOL CLEAN

Periodically blow out all air passages with dry compressed air. Remove build up of grime resulting from working green or sappy wood. The rubber boot may be cleaned with a soft damp cloth. NEVER use solvents, as they could pos- sibly dissolve or otherwise damage the material.

LUBRICATION

An automatic in-line filter-lubricator is recommended as it increases tool life and keeps the tool in sustained operation. The in-line lubricator should be regularly checked and filled with a good grade of 10W machine oil. Proper adjustment of the in-line lubricator is performed by placing a sheet of paper next to the exhaust ports and holding the throttle open approximately 30 seconds. The lubricator is properly set when a light stain of oil collects on the paper. Excessive amounts of oil should be avoided.

STORAGE

In the event that it becomes necessary to store the tool for an extended period of time (overnight, weekend, etc.), it should receive a generous amount of lubrication at that time and again when returned to service. The tool should be stored in a clean and dry environment.
