RIGHT ANGLE DRILL Model 7556
Fig. 3A
BE ALERT and brace yourself against the twisting action of
the drill, should bit jam in the work.
7. If drill stalls or becomes jammed in the hole, release trigger immediately,
remove drill bit from work and determine cause of stalling or jamming. DO
NOT SQUEEZE TRIGGER ON AND OFF IN AN ATTEMPT TO FREE A
STALLED OR JAMMED DRILL – THIS WILL DAMAGE THE MOTOR. The
direction of rotation may be reversed to help free a jammed bit. Be sure
direction of rotation is RESET before attempting to continue drilling.
8. Reduce the pressure on the drill just before the bit cuts through the work
to avoid splintering wood or stalling in metal.
9. When bit has completely penetrated work and is spinning freely,
withdraw it from the work while the motor is still running, then turn off drill.
DRILLING WOOD
SOME WOOD CONTAINS PRESERVATIVES WHICH
CAN BE TOXIC. Take extra care to prevent inhalation and skin contact
when working with these materials. Request, and follow, any safety
information available from your material supplier.
In addition to the instructions listed under GENERAL DRlLLlNG, the following
also apply:
1. When using twist drills in wood, they should be withdrawn from the hole
frequently to clear chips built up in flutes to avoid overheating and burning
work.
2. If a backing block is used to keep back of work from splintering, it
should be clamped securely in place. If a backing block is not used with
spade bits or auger bits, ease up pressure as soon as bit point breaks
through work, and complete the hole from the opposite side.
DRILLING METAL
In addition to the instructions listed under GENERAL DRlLLlNG, the following
also apply:
When drilling metal, jamming of bit is more likely than
when drilling other materials.
1. Use only good quality sharp high speed steel twist bits when drilling
metal.
