PLUNGE CUTTING

Plunge cutting is useful and time-saving in
making rough openings in softer materials. It
is not necessary to drill a hole for an inside or
pocket cut. Draw lines for the opening, hold
the saw firmly, tilt it forward so that the toe of
the saw foot rests on the work, but with the
blade well clear of the work. Start the motor,
and then very gradually lower the blade.
When it touches, continue pressing down on
the toe of the saw foot slowly pivoting the saw
like a hinge until the blade cuts through and
the foot rests flat on the work. Then saw
ahead on the line of cut line. We do not
recommend plunge cutting with a scroll blade
(Fig. 13).
To make sharp corners, cut up to the corner,
then back up slightly before rounding the

To prevent damage to the

tool when bevel or angle
cutting, the scroll mechanism must be locked
in place with the cutting edge of the blade
facing the front of the tool. If tool shifts while
cutting you may loose control and be injured.
Disconnect the cord from the power source.
Your tool is equipped with quick reference
detent stops. The foot can be adjusted and
locked to cut angles only at 0˚, 15˚, 30˚, and
45˚.
TO ADJUST: Lift foot adjustment lever in the
bottom of foot as shown, move foot slightly
backward to disengage the locking tab
(Fig. 14).
Position foot to desired angle, then push
forward to engage locking tab and lower
adjustment lever to maintain adjustment. After
adjusting foot make a sample cut to check the
angle, (Fig. 14).

METAL CUTTING

When cutting metal clamp material down. Be
extra certain that you move the saw along
slowly. Use lower speeds. Do not twist, bend,
or force the blade. If the saw jumps or
bounces, use a blade with finer teeth. If the
blade seems clogged when cutting soft metal,
use a blade with coarser teeth.
For easier cutting, lubricate the blade with a
stick of cutting wax, if available, or cutting oil
when cutting steel. Thin metal should be
sandwiched between two pieces of wood or

corner. After the opening is complete, go back
to each corner and cut it from the opposite
direction to square it off. Do not try to plunge
cut into hard materials such as steel.
Note: If the foot becomes loose you can use a
screwdriver to tighten screw located on the
foot adjustment lever, then re-adjust the foot
adjustment lever.

tightly clamped on a single piece of wood

When cutting aluminum extrusion or angle
iron, clamp the work in a bench vise and saw
close to the vise jaws.
When sawing tubing and the diameter is
larger than the blade is deep, cut through the
wall of the tubing and then insert the blade
into the cut rotating the tube as you saw.
