Proper Hand Position (Fig. 1)

WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand position as shown.

WARNING: To reduce therisk of serious personal injury, ALWAYS hold securely in anticipation of a sudden reaction.

Proper hand position requires one hand on the side handle (C), with the other hand on the main handle (D).

NOTE: Operating temperature of this tool is 19˚ to 104˚ F (-7 to +40˚ C). Using the tool outside of this temperature range will decrease the life of the tool.

Trigger Switch (Fig. 1)

To turn the tool on, depress the trigger switch (A). To stop the tool, release the trigger switch.

D25602

In chipping mode only, lock the trigger switch on, push the lock-on slider (B) upwards while depressing the trigger switch.

To deactivate the lock-on slider, depress the trigger switch once then release.

The lock-on slider may only be activated in chipping mode. The machine will stop running when trying to engage the lock-on slider in hammerdrilling mode. The motor will stop if the lock-on slider is activated when changing from chisel mode into hammerdrilling mode.

D25820, D25831, D25851

For continuous operation, move the toggle switch to the on position. To stop continuous operation, move the toggle switch to the off position.

SOFT START FEATURE

The soft start feature allows you to build up speed slowly, thus preventing the drill bit from walking off the intended hole position

when starting. The soft start feature also reduces the immediate torque reaction transmitted to the gearing and the operator if the hammer is started with the drill bit in an existing hole.
