STROKE LENGTH/LOCK-OFF SWITCH
Your tool is equipped with a dual stroke-length
/ lock-off switch located on the top of the saw.
This lever is designed for choosing the stroke
length and for locking the trigger in the "OFF"
position to help prevent accidental starts and
accidental battery discharge. The tool should
be at a complete stop before changing stroke
lengths. For the 3/4" (19 mm) stroke, move
the switch to the far left. For the 1-1/4" (32
mm) stroke, move the switch to the far right.
To activate the trigger lock, move the switch to
the center position (Fig 2).
The 1-1/4" (32 mm) stroke is useful for fast,
aggressive cutting, especially in wood.
The 3/4" (19 mm) stroke offers a wide
variety of benefits:
• Reduced vibration of workpiece when
cutting thin or fragile workpiece materials,
such as sheet metal, thin plywood, or
plaster-and-lath walls.
• Reduced depth-of-cut and blade projection
beyond the far edge of the workpiece, such
as when cutting into a wall or when cutting
a pipe that runs along a wall.
• Easier pocket/plunge cutting.
• Precise starts of cuts.
• Increased pulling power (like a drill has
more torque in low gear).*
• Less heat from lower blade travel speed,
thus longer blade life.*
*These characteristics are especially
beneficial when cutting metal.
BRAKE
When the trigger switch is released it activates
the brake to stop the saw quickly. This is
especially useful when making repetitive cuts.
VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
Your tool is equipped with a variable speed
controlled trigger switch. The tool can be
turned "ON" or "OFF" by squeezing or
releasing the trigger. The blade plunger
stroke rate can be adjusted from the minimum
to maximum nameplate stroke rate by the
pressure you apply to the trigger. Apply more
pressure to increase the speed and release
pressure to decrease speed.
Higher speed settings are generally used for
fast cutting or when softer cutting materials
such as wood, composite materials, and
plastics. Slower speed settings are generally
used when precision is required or when
cutting harder materials. Materials typically cut
using slower speeds include sheet metal,
conduit, and pipe.

BLADE SELECTION
No one blade can be efficient on all cutting
jobs. Different materials require specially
designed blades. Since your reciprocating
saw can cut so many materials, many types of
BOSCH blades are available. Be sure to use
the proper blade to insure proper cutting
performance.
