ASSEMBLY AND ADJUSTMENTS

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. 

An accidental start-up can cause injury.

Side Handle (Fig. 2)

WARNING: 

To reduce the risk of personal injury, 

ALWAYS

 operate the tool with the side handle properly 

installed and securely tightened. Failure to do so may 

result in the side handle slipping during tool operation 

and subsequent loss of control. Hold tool with both 

hands to maximize control.
A side handle comes assembled with this rotary 

hammer. The side handle (C) can be fitted to suit both 

right-hand and left-hand users.

TO ADJUST THE SIDE HANDLE

  1. Loosen the side handle (C) by turning 

it 

counterclockwise.

  2. Rotate the side handle to the desired position.
  3. Tighten the side handle by turning it clockwise 

until you are sure the side handle won’t slip.

TO CHANGE SIDES

For right-hand users: 

slide the side handle clamp 

over the chuck, handle at the left. 

For left-hand users:

 slide the side handle clamp 

over the chuck, handle at the right. 

Trigger Switch (Fig. 1)

To start the rotary hammer, depress the trigger switch (A). To stop rotary hammer, 

release the switch. 

NOTE: 

Use lower speeds for starting holes without a centerpunch, drilling in metal, 

plastics or ceramics, or driving screws. Higher speeds are better for drilling in 
masonry for maximum efficiency.

VARIABLE SPEED

The variable speed trigger switch (A) permits speed control. The farther the trigger 

switch is depressed, the higher the speed of the drill. 

Reversing Lever (Fig. 3)

The reversing lever (G) is used to reverse the rotary 

hammer for backing out fasteners or jammed bits in 

drill-only mode. 

WARNING: 

When reversing to clear jammed bits, 

be ready for strong reactive torque. 
To reverse the rotary hammer, turn it off and align 

the reversing lever (G) with the yellow arrow pointing 

backward (viewed when holding drill in operating 

position). 
To position the lever for forward operation, turn the 

rotary hammer off and align the reversing lever (G) 

with the yellow arrow pointing forward (viewed when 

holding drill in operating position).
