INTENDED USE
These heavy-duty rotary hammers have been designed for professional drilling and hammer-
drilling, screwdriving and light chipping at various work sites (i.e., construction sites). DO NOT 
use under wet conditions or in presence of flammable liquids or gases.
These heavy-duty rotary hammers are professional power tools. DO NOT let children come into 
contact with the tool. Supervision is required for those under 16 years of age.

both hands to maximize control.
A side handle (A) is supplied with this rotary hammer. It clamps to the front of the gear case 
without depth rod (B) as shown in Figure 1 and can be rotated 360° to permit right- or left-hand 
use. The side handle can be tightened by rotating the black plastic portion of the side handle 
clockwise and loosened by rotating it counterclockwise.

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

VARIABLE SPEED TRIGGER
The variable speed trigger switch (D) permits speed control. The farther the trigger switch is 
depressed, the higher the speed of the drill. 
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.

power supply. Failure to do so will cause the hammerdrill to start immediately the next time it is 
plugged in. Damage or personal injury could result.
The lock-on button is for use only when the rotary hammer is stationary, mounted in a drill press 
stand or for chipping applications.
Before using the tool each time, be sure that the lock-on button release mechanism is working 
freely.

points to the corresponding symbol as shown.

HAMMER-ONLY MODE
For light chiseling, depress the button and turn the mode selector so the yellow arrow points to 
the corresponding symbol as shown. 
NOTE: The yellow arrow on the mode selector MUST be aligned with the one of the symbols 
at all times. There are no operable positions between the positions.

on the tool and bits may get extremely hot during operation. Small bits of broken material may 
damage bare hands.
CAUTION: Do not use chipping bits in this tool. Using chipping bits may cause the tool to bind-
up and damage to the tool may occur.
To insert bit, insert shank of bit about 3/4" (19 mm) into chuck. Push and rotate bit until it locks in 
place. The bit will be securely held.
To release bit, pull the sleeve (J) back and remove the bit.

If the drill bit becomes jammed or caught, the drive to the drill spindle is interrupted. Because 
of the forces that occur as a result, always hold the machine securely with both hands and take 
a firm stance.

The machine is intended for hammerdrilling in concrete, brick and stone. It is also suitable for 
drilling without impact in wood, metal, ceramic and plastic. Machines with electronic control and 
right/left rotation are also suitable for screw driving and thread cutting.

The machine is intended for chipping in concrete, brick and stone. 

or clamped firmly. If drilling thin material, use a wood “back-up” block to prevent damage to the 
material.
  1. Always unplug the drill when attaching or changing bits or accessories.
  2. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits, power auger bits, or 

hole saws. For METAL, use steel twist drill bits or hole saws. For MASONRY, such as brick, 
cement, cinder block, etc., use carbide-tipped bits rated for percussion drilling. Be sure the 
material to be drilled is anchored or clamped firmly. If drilling thin material, use a wood “back-
up” block to prevent damage to the material.

  3.  Always apply pressure in a straight line with the bit. Use enough pressure to keep drill biting, 

but do not push hard enough to stall the motor or deflect the bit.

  4. Hold tool firmly to control the twisting action of the drill.
 5. IF DRILL STALLS, it is usually because it is being overloaded or improperly used. RELEASE 

TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO 
NOT CLICK TRIGGER ON AND OFF IN AN AT TEMPT TO START A STALLED DRILL 
— THIS CAN DAMAGE THE DRILL.

  6. To minimize stalling or breaking through the material, reduce pressure on drill and ease the 

bit through the last fractional part of the hole.

  7. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent 

jamming.

  8.  With variable speed drills there is no need to center punch the point to be drilled. Use a slow 

speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep 
enough to drill without the bit skipping out.

The D25314 is equipped with a removable quick change SDS chuck as well as a removable 
three jaw keyless chuck. The hammer mechanism  does not function when the three jaw keyless 
chuck is used.
Both the SDS and three jaw keyless chuck can be easily removed by turning the collar (K) into 
the unlocked position (L) to release the chuck (Fig. 6).
The SDS and three jaw keyless chuck can be easily attached by inserting the chuck into the 
spindle of the tool and turning the collar to the locked position (M). The chuck will click when 
properly installed.

DRILLING IN METAL 
(D25113, D25213, D25313, D25314)
An SDS to round shank adaptor chuck is required. Ensure that tool is in drill-only mode. 
(D25111, D25211 has no drill-only mode). Start drilling with slow speed and increase to full 
power while applying firm pressure on the tool. A smooth even flow of metal chips indicates the 
proper drilling rate. Use a cutting lubricant when drilling metals. The exceptions are cast iron and 
brass which should be drilled dry. The cutting lubricants that work best are sulphurized cutting 
oil or lard oil; bacon-grease will also serve the purpose.
NOTE: Large [(5/16" to 1/2") (7.9 mm to 12.7 mm)] holes in steel can be made easier if a pilot 
hole [(5/32" to 3/16") (4 mm to 4.8 mm)] is drilled first.

DRILLING IN WOOD 
(D25113, D25213, D25313, D25314)
An SDS to round shank adaptor chuck is required. Ensure that tool is in drill-only mode. D25111, 
D25211 have no drill-only mode). Start drilling with slow speed and increase to full power while 
applying firm pressure on the tool. Holes in wood can be made with the same twist drills used 
for metal. These bits may overheat unless pulled out frequently to clear chips from the flutes. For 
larger holes, use spade bits, power auger bits, or hole saws. Work that is apt to splinter should 
be backed up with a block of wood. 

DRILLING IN MASONRY
(D25113, D25213, D25313, D25314)
When drilling in masonry, use SDS carbide tipped bits rated for percussion drilling and be 
certain that the bit is sharp. Use a constant and firm force on the tool to drill most effectively. A 
smooth, even flow of dust indicates the proper drilling rate.

TO ADJUST THE DEPTH ROD 
  1. Push in and hold the button on the side handle. 
  2. Move the depth rod (B) so the distance between the end of the rod and the end of the bit 

equals the desired drilling depth. 

  3.  Release the button to lock rod into position.  When drilling with the depth rod, stop when end 

of rod reaches surface of material.

Your tool was properly lubricated before leaving the factory. In from two to six months, depending 
upon use, take or send your tool to an authorized service center for a complete cleaning, 
inspection and lubrication. Tools used constantly on production jobs will need relubrication more 
often. Also, tools “out of service” for long periods should be relubricated before being put back 
to work.
