Metal cUttiNG
This saw has different metal cutting capacities depending upon the
type of blade being used and metal being cut.
alWayS clamp the work down to prevent it from slipping.
Use a finer blade for ferrous metals and a coarse blade for non-
ferrous metals.
When cutting thin gauge sheet metals, alWayS clamp wood on
both sides of the sheet. This will give you a clean cut without excess
vibration or tearing of the metal.
Do Not force the cutting blade. Forcing the blade will reduce blade
life and cause the blade to break.
Note: We recommend that you spread a thin film of oil or other
coolant along the line of cut ahead of the saw. This will allow easier
operation and help extend blade life. When cutting aluminum, use
kerosene.
Pocket cUttiNG (Soft materials only) (See fig. J, k)
Mark the pocket or internal hole to be cut out. Insert the special
cutting blade with blade teeth facing down and clamp securely. Angle
the saw so that the back edge of the blade guard is resting on the
work surface. Use a slow speed to start the cut to avoid breaking the
blade but increase to correct speed once the cut has started. With
the blade guard held firmly against the work surface, start a slow
but controlled upward swing of the saw. The blade will cut into and
through the material. Always ensure the blade is completely through
the material before cutting the remainder of the pocket.
