For Your Own Safety Read Instruction Manual  
Before Operating This Equipment  
The purpose of safety symbols is to attract your attention to possible hazard-  
ous conditions. This manual uses a series of symbols and signal words which  
are intended to convey the level of importance of the safety messages. The  
progression of symbols is described below. Remember that safety messages by  
themselves do not eliminate danger and are not a substitute for proper accident  
prevention measures.  
Indicates an imminent hazardous situation which, if  
not avoided, WILL result in death or serious injury.  
Indicates a potentially hazardous situation which, if  
not avoided, COULD result in death or serious injury.  
Indicates a potentially hazardous situation which, if  
not avoided, MAY result in minor or moderate injury.  
It may also be used to alert against unsafe practices.  
This symbol is used to alert the user to useful infor-  
mation about proper operation of the equipment.

depth stop  
operation  
Use the depth stop to halt the advance of  
the bit at the desired drilling depth.  
to use the hammer drill:  
1. if desired, slide the dust cup onto the  
bit with the cupped side facing the work  
surface. install the drill bit as instructed  
on the previous page.  
to attach the depth stop:  
1. disConneCt tooL FroM poWer!  
2. Loosen the auxiliary handle and slide  
the depth stop into the hole on the  
handle bracket (see figure 5).  
2. adjust the depth stop for the drilling  
depth desired.  
3. put on the appropriate personal  
protective equipment.  
note: Make sure the bend in the depth  
stop is next to the bit. This will ensure  
that the gauge will contact the work  
surface next to the hole being drilled.  
4. Firmly hold the drill with one hand on  
the grip and the other on the auxiliary  
handle, then position the tip of the bit  
on the work surface with firm but not  
heavy pressure.

3. adjust the gauge to the proper depth  
for the operation, then secure it in place  
by re-tightening the auxiliary handle.  
5. pull the trigger to turn the drill ON, and  
begin drilling.  
note: Depending on the drilling depth,  
you may need to clear the bit while drill-  
ing by moving the rotating bit in and out  
of the hole.  
dust and debris from hammer drill  
operation can be harmful to eyes,  
respiratory system, face, and skin.  
also, the noise can cause hearing  
loss over time. always wear heavy  
work gloves and long sleeves, safe-  
ty goggles and faceshield, respira-  
tor, and hearing protection during  
operation.  
6. When the hole is complete, remove the  
bit from the hole while it is still rotat-  
ing and release the trigger to turn the  
drill OFF. allow the bit to stop rotating  
before putting the drill down.
