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
