Preparing the Saw
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.
INSTALLING A BLADE
!WARNING Unplug tool from power source before changing
blade or making any adjustments.
The CLIC™ wrenchless blade change clamp can only be operated when the plunger is fully extended. To fully extend plunger, while blade is mounted, hook the blade teeth on a scrap workpiece or hidden area and pull the tool backwards. If no blade is in the plunger, gently press trigger switch to position plunger to it's fully extended position.
Simply rotate the blade release knob clockwise to open the clamp; insert the blade until it stops and release the knob. The spring loaded mechanism will lock the clamp against the blade. Push in and pull out on the blade to be sure it is held securely. The blade may be inserted with the teeth facing up or down.
!WARNING Some specialty blades (such as 7º kant) cannot be used in
the inverted position. Always check to be sure blade does not contact footplate in any stroke position or footplate position.
NOTE: If you require a standard blade clamp for any reason (extra thick blades, very thin blades, etc.) a packet is available for the saw which contains a clamp, hex key, screw and lockwasher. To use the standard clamp, remove the quick change clamp assembly by unscrewing the set screw which holds it onto the draw bar. Then assemble the standard clamp with the screw and lockwasher provided.
Operating Instructions
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.
2-SPEED SELECTOR LEVER
In addition to the variable speed trigger switch, the saw is also equipped with a two speed switch which is controlled with a selector lever .
When the selector lever is pointed to the left, the saw will operate up to its maximum speed of 2700 SPM (strokes per minute). This speed setting is generally used when cutting softer materials such as wood.
When the selector lever is pointed to the right, the saw will operate up to the lower speed of 1900 SPM. This speed setting is generally used when cutting harder materials such as steel.
FOOTPLATE ADJUSTMENT
The footplate pivots in order to keep a relatively large surface in contact with the work. It can be locked into 1 of 3 positions to optimize blade life and/or to limit blade protrusion beyond the end of the footplate when cutting into large diameter pipe or into walls. To adjust the footplate position, simply push the area 4 indicated by the symbol on the boot and move the footplate into the desired position. The locking mechanism is spring loaded to lock into one of the 3 notches on the footplate bracket.
! WARNING | Pushing the footplate release |

cause the foot to release from the desired settings.
ORBIT SELECTOR
To obtain the best cutting advance in various types of materials, your saw has a blade orbit selector to adjust the swing of the saw blade. When cutting into wood and plastic, as well as other soft materials, a larger swing of the blade is desired. There are two orbit selector positions (see figure page 6). The
