METAL CUTTING (FIGURE 8)
• 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: 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 9)
• 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
and the moving blade will clear the
surface.
• Switch motor on, permitting blade to
obtain 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 firmly 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
UNPLUG SAW AND REMOVE ACCESSORY WHEN PERFORMING ANY CLEANING
OR OTHER MAINTENANCE. WHEN SERVICING USE ONLY IDENTICAL
REPLACEMENT PARTS.
Use only mild soap and a damp cloth to clean the tool. Never let any liquid get inside the
tool; never immerse any part of the tool into a liquid.
• 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 clean
cloths to remove dirt, carbon dust etc.
• 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 and drywall dust are highly abrasive to bearings, brushes,
commutator, etc. During any use on fiberglass or drywall it is extremely important
that the tool be cleaned frequently by blowing with an air jet.
LUBRICATION
Porter Cable tools are properly lubricated at the factory and are ready for use. Tools
should be lubricated regularly every year depending on usage. (Tools used on heavy
duty jobs and tools exposed to heat may require more frequent lubrication.) This
lubrication should be attempted only by trained power tool repairperson's such as those
at Porter Cable service centers or in other qualified service personnel.
