air supply
WarNiNG! Ensure the air supply is clean and does not exceed 90 psi while operating the drill.
‰
Too high an air pressure and unclean air will cause 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 the drill air valve (or trigger) is not depressed before connecting to the air supply.
4.1.3.
You will require an air pressure between 70-90psi, and an air flow according to the specification above.
4.1.4.
drain the air tank daily. Water in the air line will damage the drill and invalidate your warranty.
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).
4.1.7.
The minimum hose diameter should be 1/4" I.D. and fittings must have the same inside dimensions.
4.1.8.
Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all
connections are secure.
4.2.
cOupliNGs
4.2.1.
Vibration may cause failure if a quick change coupling is connected directly to the air drill.
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 figs.1 & 2.
4.3.
fiTTiNG haNdle
4.3.1.
Slide the split brass ring over the chuck and onto the main black body of the drill. Squeeze the split thread together and screw the
handle partially onto the ring. move the handle to your desired orientation and continue to screw the handle until it is locked in
position.

WarNiNG! ensure you read, understand and apply safety instructions before use.

5.1.
drill biT fiTTiNG
WarNiNG! Unplug from the air supply before placing bit into chuck.
‰
5.1.1.
Regularly check the drill bit and always change if worn, cracked or otherwise damaged.
5.1.2.
Open or close the chuck jaws (fig 3.1) to a point where the opening is slightly larger than the drill or tool bit to be used. Insert the drill
bit into the chuck as far as it will go. Rotate the forward section of the chuck (fig 3.2) clockwise, in order to secure the drill bit.
5.1.3.
Connect air supply to drill. Squeeze the trigger (fig 3.3) 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 of bearings.

WarNiNG! Ensure you wear approved safety goggles and any other safety item required for the job. Ensure chuck is locked before
‰
using the drill. Also ensure that all other safety requirements are followed.
5.2.1.
Connect drill to air supply.
5.2.2.
For drilling purposes 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). If not, flip the lever over to the forward position.
5.2.3.
Hold tool firmly and place the bit tip to the point to be drilled.
5.2.4.
depress the trigger to start drill. move the drill bit into the work piece
applying only enough pressure to keep the bit cutting. dO NOT
force or apply side pressure to elongate the hole.
5.2.5.
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.
5.2.6.
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.
5.2.7.
For hard smooth surfaces use a centre punch to mark desired hole
location. This will prevent bit from slipping as your start to drill.
5.2.8.
A pilot hole may be necessary to assist the final drill size through the
work piece. Lock a pilot drill (smaller size drill than the finished
hole size) into the chuck 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 and place the bit at the entrance of the pilot hole and depress the trigger.
WarNiNG! Be prepared for drill binding on 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.
5.2.9.
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 (the reverse action is also useful for undoing fixings).
