working correctly before starting work.
4.2.1.
DO NOT
allow drill to run freely for an extended period of time as this will
shorten the life of bearings.
WARNING! Ensure you wear approved safety goggles and any other safety
items required for the job. Also ensure that all other safety requirements are
followed
4.3. USING THE DRILL
4.3.1. Ensure the drill is turning in the forward direction by checking that the lever
adjacent to the trigger
is next to the forward symbol “F” (fig 3). If not, push
the lever over to the forward position.
4.3.2. Hold tool firmly and place the bit tip to the point to be drilled.
4.3.3. Depress the trigger to start drill. Move the drill bit into the workpiece
applying only enough pressure to keep the bit cutting. DO NOT force or
apply side pressure to elongate the hole.
4.3.4. If the material to be drilled is free standing it should be secured in a vice or
with clamps to keep it from turning as the drill bit rotates.
4.3.5. When drilling metals, use a light oil on the drill bit to keep it from
overheating. Oil will prolong life of bit and improve the drilling action.
4.3.6 For hard smooth surfaces use a centre punch to mark desired hole location.
This will prevent bit from slipping as your start to drill.
4.3.7 A pilot hole may be necessary to assist the final drill size through the
workpiece. Lock a pilot drill (smaller size drill than the finished hole size) into
the chuck. Follow steps 4.3.1. to 4.3.3. above and drill a pilot hole in the
middle of the centre punch mark where final hole is to be drilled. Insert the
final sized bit in chuck. Hold drill firmly, place the bit at the entrance of the
pilot hole and depress the trigger.
WARNING!
Be prepared for drill binding or break through. When these situations
occur the drill
has a tendency to grab and kick in the opposite direction
which could cause loss of control. If you are not prepared, this loss of
control can result in damage and/or personal injury.
4.3.8 If the bit jams in the workpiece or if the drill stalls, release the trigger switch
immediately. Remove the bit from the workpiece and determine the reason
for jamming. It may be necessary to reverse the direction of rotation by
moving the lever adjacent to the
trigger to the reverse “R” position (fig 3).
