Black & Decker Spitfire 5013 - Manual (Page 6)

Hammer Drilling
1. Position selector lever in the “hammer” position.
2. When drilling, use just enough force on the hammer to keep it from
bouncing excessively or “rising” off the bit. Too much force will cause
slower drilling speeds, overheating, and a lower drilling rate.
3. Drill straight, keeping the bit at a right angle to the work. Do not exert
side pressure on the bit when drilling as this will cause clogging of the bit
flutes and a slower drilling speed.
4. When drilling deep holes, if the hammer speed starts to drop off, pull the
bit partially out of the hole with the tool still running to help clear debris
from the hole.
5. Do not pour water into the hole to settle dust. Water causes clogging of
bit flutes which will tend to make the bit bind in the hole.
Drilling
Always unplug the tool when attaching or changing bits or accessories.

Position selector lever in the “drill” position.
Use sharp drill bits only. For WOOD, use twist drill bits, spade bits,
power auger bits, or hole saws. For METAL, use high speed steel twist
bits or hole saws.
Be sure the material to be drilled Is anchored or clamped firmly. If drilling
thin material, use a “back-up” block to prevent damage to the material.
Always apply pressure in a straight line with the bit. Use enough pressure
to keep the bit biting, but do not push hard enough to stall the motor or
deflect the bit.
Flold tool firmly to control the twisting action.
IF TOOL STALLS, it is usually because it is being overloaded. RELEASE
TRIGGER IMMEDIATELY, remove bit from work, and determine cause of
stalling. Do not click trigger off and on in an attempt to start a stalled
tool. This can damage the tool.
7. To minimize stalling or breaking through the material, reduce pressure
on hammer and ease the bit through the last fractional part of the hole.
8. Keep the motor running when pulling the bit back out of a drilled hole.
This will help prevent jamming.
9. With the variable speed feature there is no need to center punch the point
to be drilled. Use a slow speed to start the hole and accelerate by squeez­
ing the trigger harder when the hole is deep enough to drill without the
bit skipping out.
Maintenance
Disconnect tool from the power supply and periodically take the following
maintenance action:
1. Clean any dirt build-up out of the air slots in the housing.
2. Check the condition of the power supply cord, plug and extension cord.
Repair at once if damaged.
3. Your hammer has a maintenance feature called the “B&D check point
system.” When the tool requires motor brush replacement, it will shut
down automatically. At this time the tool should be taken to an authorized
service center for cleaning, regreasing, and preventative maintenance.
