Maintenance - Black & Decker DR260 Instruction Manual

• Do not mix or stir flammable liquids
labeled accordingly.
Screwdriving
1. Pull the trigger switch applying pressure in a straight line
with the bit until the fastener is seated at the desired
depth in the workpiece.
Recommendations for screwdriving
• Start with pressure on the variable speed trigger, then
advance to higher pressure on the variable speed trigger
to avoid damage to the workpiece or fastener.
• Make some practice runs in scrap or on unseen areas of
the workpiece to determine the proper position of the
mode selection collar.
Drilling
iMPORTAnT: For MASONRY, such as brick, cement, cinder
block, etc., use carbide-tipped masonry bits.
1. Place drill bit in contact with the workpiece.
nOTE: Use sharp drill bit only.
2. Pull the trigger switch applying pressure in a straight line
with the bit until it reaches the desired depth.

WARNING: Drill may stall if overloaded causing a
sudden twist. Always expect the stall. Grip the drill
firmly to control the twisting action and avoid injury.
3. Keep the motor running when pulling the bit back out of
a drilled hole to prevent jamming.
Recommendations for Drilling
• When drilling, always apply pressure in a straight line
with the bit, but do not push hard enough to stall the
motor or deflect the bit.

‑ To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the
last fractional part of the hole.
• Large holes (5/16" to 1/2" [7.9 mm to 12.7 mm]) in steel
can be made easier if a pilot hole (5/32" to 3/16" [4 mm
to 4.8 mm]) is drilled first.
• If drilling thin material or material that is prone to splinter,
use a wood "back-up" block to prevent damage to
the workpiece.
Hammerdrilling
DR340
iMPORTAnT: Use carbide-tipped or masonry bits rated for
percussion drilling only.
1. Pull the trigger, applying just enough pressure on the
hammer to keep it from bouncing excessively or "rising"
off the bit.
Recommendations for hammerdrilling
• Too much force will cause slower drilling speeds,
overheating, and a lower drilling rate.
• A smooth even flow of material indicates the proper
drilling rate.
• Drill straight, keeping the bit at a right angle to the work.
Do not exert side pressure on the bit when drillling as
this will cause clogging of the bit flutes and a slower
drilling speed.
• When drilling deep holes, if the hammer speed starts to
drop off, pull the bit partially out of the hole with tool still
running to help clear debris from the hole.

MAINTENANCE


WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start‑up can cause injury.
Your BLACK+DECKER power tool has been designed to
operate over a long period of time with a minimum of
maintenance. Continuous satisfactory operation depends
upon proper tool care and regular cleaning.
Cleaning

WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the risk
of eye injury, always wear ANSI Z87.1 approved eye
protection when performing this procedure.

WARNING: Never use solvents or other harsh
chemicals for cleaning the non‑metallic parts of the
tool. These chemicals may weaken the plastic materials
used in these parts. Use a cloth dampened only with
water and mild soap. Never let any liquid get inside the
tool; never immerse any part of the tool into a liquid.
