ROTATING / CHANGING THE CUTTERS
Always unplug the tool from the power source
before changing accessories or making any
adjustments.
The upper and lower cutters and are identical,
each has four cutting edges and can be
interchanged or rotated.
When the cutting performance is
unsatisfactory, rotate each cutter 90° or
replace.
Loosen the screw of the respective cutter,
rotate the cutter 90° and re-tighten the screw.
Ensure that the lower cutter rests against the
adjustment screw.
ADjUSTING THE CUTTER CLEARANCE
The cutter clearance a has been
adjusted at the factory to 0.008"
and does not need to be
changed.
For working primarily with ductile, brittle or thin
sheet metal, the following values/cutter
clearance gives optimum cutting results:
Metal
Metal thickness
Cutter clearance
a
Thin/ductile
0.012"- 0.024"
0.004"
Brittle
0.031" - 0.047"
0.010"
Brittle
0.051" - 0.063"
0.012"
Loosen screw of the lower cutter and adjust
with the adjustment screw to the required
clearance
a
. Check the clearance with a
gauge. Retighten the screw (Fig. 1).
The cutters must not touch
each other.
The use of any accessory or
attachment
other
than
recommended in this instruction manual or the
BOSCH Catalog may present a risk of personal
injury.

CAUTION
GENERAL INFORMATION
Following a few simple tips will reduce wear
on the tool and the chance of injury to the
user.
With the tool unplugged from the power
supply and the ON/OFF Switch in the “OFF”
position, become familiar with handling the
shear and learning the location of its parts.
Secure or clamp small workpieces to be cut to
prevent slippage.
Inspect the blades for excessive wear, rotate
or replace if necessary.
Always direct the cord toward the rear, and
away from the shear. Keep it away from
sharp edges.
Never start the shear with the blades in
contact with the material being cut.
Do not exceed recommended capacities for
this shear. Premature blade failure will occur
when the shear is over-gaged.
To extend blade life and prevent corrosion,
occasional light lubrication of the blades is
recommended. Any light weight machine oil
can be used for this purpose.
SLIDE ON-OFF SWITCH WITH LOCK
The tool is switched “ON” by the switch
button located at the side of the motor
housing. The switch can be locked in the
“ON” position, a convenience for long cutting
operations.
TO TURN THE TOOL “ON” without locking
it, slide the switch button forward by applying
pressure ONLY at the REAR portion of the
button. When pressure is released the switch
button will snap to “OFF” position.
TO LOCK THE SWITCH “ON”, slide the
switch button forward and press “IN” the
FRONT portion.
TO UNLOCK THE SWITCH, simply press
and release the REAR portion of the button.
Switch is spring loaded and will snap back
automatically.
Upper and Lower Cutters are the same. Reorder #2 608 635 243.
