SAWING
:
To reduce the risk of personal injury, always hold saw firmly with both
hands on the handles.
:
Never attempt to use this tool by resting it upside down on a work
surface and bringing the material to the tool. Always securely clamp the workpiece and
bring the tool to the workpiece, securely holding the tool with two hands as shown in
Figure E.
Place the wider portion of the saw foot plate on that part of the work piece which is
solidly supported, not on the section that will fall off when the cut is made. As
examples, Figure E illustrates the RIGHT way to cut off the end of a board. Always
clamp work. Donʼt try to hold short pieces by hand! Remember to support cantilevered
and overhanging material. Use caution when sawing material from below.
Be sure saw is up to full speed before blade contacts material to be cut. Starting saw
with blade against material to be cut or pushed forward into kerf can result in kickback.
Push the saw forward at a speed which allows the blade to cut without laboring.
Hardness and toughness can vary even in the same piece of material, and knotty or
damp sections can put a heavy load on the saw. When this happens, push the saw
more slowly, but hard enough to keep working without much decrease in speed.
Forcing the saw can cause rough cuts, inaccuracy, kickback, and over-heating of the
motor. Should your cut begin to go off the line, donʼt try to force it back on. Release the
switch and allow blade to come to a complete stop. Then you can withdraw the saw,
sight anew, and start a new cut slightly inside the wrong one. In any event, withdraw
the saw if you must shift the cut. Forcing a correction inside the cut can stall the saw
and lead to kickback.
IF SAW STALLS, RELEASE THE TRIGGER AND BACK THE SAW UNTIL IT IS
LOOSE. BE SURE BLADE IS STRAIGHT IN THE CUT AND CLEAR OF THE
CUTTING EDGE BEFORE RESTARTING.
As you finish a cut, release the trigger and allow the blade to stop before lifting the saw
from the work. As you lift the saw, the spring tensioned telescoping guard will
automatically close under the blade. Remember the blade is exposed until this occurs.
Never reach under the work for any reason. When you have to retract the telescoping
guard manually (as is necessary for starting pocket cuts) always use the retracting lever.
NOTE: When cutting thin strips, be careful to ensure that small cutoff pieces donʼt hang
up on inside of lower guard.
HINTS FOR OPTIMUM USE
• As some splintering along the line of cut on the top side of the workpiece cannot be
avoided, cut on the side where splintering is acceptable.
• Where splintering is to be minimized, e.g. when cutting laminates, clamp a piece of
plywood onto the top of the workpiece.
POCKET CUTTING (FIGURE O)
:
Never tie the blade guard in a raised position. Never move the saw
backwards when pocket cutting. This may cause the unit to raise up off the work
surface which could cause injury.
A pocket cut is one that is made in a floor, wall, or
other flat surface.
• Adjust the saw foot plate so the blade cuts at
desired depth.
• Tilt the saw forward and rest front of the foot plate
on material to be cut.
• Using the retracting lever, retract lower blade
guard to an upward position. Lower rear of foot
plate until blade teeth almost touch cutting line.
• Release the blade guard (its contact with the work
will keep it in position to open freely as you start
the cut). Remove hand from guard lever and
firmly grip auxiliary handle (3), as shown in figure
O. Position your body and arm to allow you to
resist kickback if it occurs.
