Assembly
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
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
a 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" |
Upper and Lower Cutters are the same. Reorder #2 608 635 243.
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).
! CAUTION | The cutters must not touch | |
each other. | ||

!WARNING 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.
Operating Instructions
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
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.
