Maintenance - Stanley SCH121 Original Instructions Manual

ENGLISH
(Original instructions)
• Use sharp drill bits only. For WOOD, use twist drill bits, spade
bits, or hole saws. For METAL, use high-speed steel (HHS) twist
drill bits or hole saws.
• 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.
• Hold tool firmly with both hands to control the twisting action of
the drill.
WARNING: The drill may stall if overloaded causing a
sudden twist. Always expect the stall. Grip the drill firmly
with both hands to control the twisting action and avoid
injury.
• 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 ATTEMPT TO START A
STALLED DRILL — THIS CAN DAMAGE THE DRILL.
• To minimize stalling or breaking through the material, reduce
pressure on drill and ease the bit through the last fractional part
of the hole.
• Keep the motor running when pulling the bit back out of a drilled
hole. This will help prevent jamming.
• 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.
Hammer drill operation (Fig. D)
1. Turn the collar (9) to the hammer drill symbol.
2. Select the high speed setting by sliding the selector forward
(towards the chuck). Important: Use carbide tipped or masonry
bits only.
3. Drill with just enough force Aon the hammer to keep it from
bouncing excessively or "rising" off the bit. Too much force will
cause slower drilling speeds, overheating and lower drilling rate.
4. 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.
5. 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.
NOTE: A smooth, even flow of dust from the hole indicates proper
drilling rate.
Operation as a screwdriver
Select the desired speed/torque range using the dual range gear
shifter on the top of tool to match the speed and torque to the
planned operation. Insert the desired fastener accessory into the
chuck as you would any drill bit. Make a few practice runs in scrap or
unseen areas to determine the proper position of the clutch collar.
