TO MOUNT IN REAR POSITION (FIG. 3)
1. Unscrew the side handle (C) and remove it from the side handle
mounting assembly. Leave the side handle mounting assembly in

Active Vibration Control (Fig. 1)
D25602, D25831, D25851
For best vibration control, hold the tool with one hand on the main
handle (D) and the other hand on the side handle (C). Apply just
enough pressure so the damping device on the main handle is
approximately midstroke. The hammer only needs enough pressure
to engage the active vibraton control. Applying too much pressure
will not make the tool drill or chip faster and active vibration control
will not engage.
Inserting and Removing Spline Drive

D25851
WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments
or accessories.
1. Insert the bit shank into the tool holder (M) as far as it will go. The
groove on the chisel shank (Q) must be aligned with the symbol
(R) on the toolholder. If inserted correctly, the locking sleeve (P)
moves back to the end position and shows a closed lock symbol.
2. Pull on the bit to be sure that it is properly locked.
