4. prepAriNG Drill for use
4.1.
Air supply
wArNiNG! ensure the air supply is clean and does not exceed 90 psi while operating the tool. Too high an air pressure and unclean
‰
air will shorten the product life due to excessive wear, and may be dangerous causing damage and/or personal injury.
4.1.1.
Recommended hook-up procedure is shown in fig 1.
4.1.2.
Ensure tool air valve (or trigger) is in "off" position before connecting to the air supply.
4.1.3.
You will require an air pressure of 90psi, and an air flow according to specification.
4.1.4.
drain the air tank daily. Water in the air line will damage the tool.
4.1.5.
Clean air inlet filter weekly.
4.1.6.
line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose diameter should be
1/4" I.d. and fittings must have the same inside dimensions.
4.1.7.
Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all
connections are secure.
4.2.
Couplings.
Vibration may cause failure if a quick change coupling is connected directly to the tool.
To overcome this, connect a leader hose - Sealey model number AH2R or AH2R/38 - to the drill.. A quick
change coupling may then be used to connect the leader hose to the air line recoil hose. See fig 1 & 2.
5. operAtioN
wArNiNG! ensure you read, understand and apply safety instructions before use.
‰
wArNiNG! Unplug from the air supply before placing bit into chuck.
‰
5.1.
Drill bit fittiNG. Regularly check the drill bit and always change if worn, cracked or
otherwise damaged.
5.1.1.
open or close the chuck jaws to a point where the opening is slightly larger than the drill
or tool bit to be used by unscrewing the chuck (fig 3). Insert the drill bit into the
chuck as far as it will go. Tighten the chuck securely.
5.1.2.
Connect air supply to drill. Squeeze the trigger to check that the drill is working correctly
before starting work.
Do Not allow drill to run freely for an extended period of time as this will shorten the life
8
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.
5.2.
usiNG the Drill
5.2.1.
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 4). If not, push the lever over to the forward position.
5.2.2.
Hold tool firmly and place the bit tip to the point to be drilled.
5.2.3.
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.
5.2.4.
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.
5.2.5.
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.
5.2.6.
For hard smooth surfaces use a centre punch to mark desired hole location. This will prevent bit from slipping as your start to drill.
5.2.7.
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 5.2.1. to 5.2.3. 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.
5.2.8.
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 4).
