2. INTRODUCTION & SPECIFICATION
3.1. Air Supply
pWARNING! 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.
3.1.1. Ensure the drill air valve (or trigger) is not depressed before connecting to the air supply.
3.1.2. You will require an air pressure between 70-90psi, and an air flow according to the specification above.
3.1.3. Drain the air tank daily. Water in the air line will damage the drill and invalidate your warranty.
3.1.4. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig 1.
3.1.5. 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.
3.1.6. Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that
all connections are secure.
3.2. Couplings
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.
p p
WARNING! Disconnect drill from air supply before changing drill bit, servicing or performing
maintenance.
5.1. Replace or repair damaged parts. Use genuine parts only. Unauthorised parts may be dangerous and
will invalidate the warranty.
5.1. Lubricate the drill daily with a few drops of good grade air tool oil, such as Sealey ATO/500 or
ATO/1000, dripped into the air inlet before use or dispensed automatically through an air system oiler,
such as Sealey model SA100L or SA1/L.
5.2. Clean the drill after use and change the bit when worn or damaged.
5.3. Loss of power or erratic action may be due to the following:
a) Excessive drain on the air supply. Moisture or restriction in the air line. Incorrect size or type of hose
connectors. To remedy check the air supply and follow instructions in Section 3.
b) Grit or gum deposits in the drill may also reduce performance. Flush the drill with gum solvent oil or an
equal mixture of SAE No 10 oil and kerosene. Allow to dry before use.
If you continue to experience problems, contact your local Sealey service agent.
5.4. For a full service contact your local Sealey service agent.
5.5. When not in use, disconnect from air supply, clean drill and store in a safe, dry, childproof location.

WARNING! Unplug from the air supply before inserting the hexagonal key wrench.
Note: Numbers in brackets refer to Item Numbers in the parts list.
4.1. DRILL BIT CHANGING. Regularly check the drill bit and always change if worn, cracked or otherwise damaged.
4.1.1 Rotate the adjustment attachment (42), in the direction of the arrow
shown in fig. 3, sufficiently to gain access to the hexagonal screw
(46) in the bit holder (33).
4.1.2. Using the hexagonal key wrench (45), loosen the hexagonal screw to
allow removal of the drill bit (36).
4.1.3. Insert a new drill (36), tighten the hexagonal screw and remove
the hexagonal key wrench.
pWARNING! Ensure you remove the hexagonal key wrench before
starting the drill.
4.2. Connect air supply to drill. Squeeze the trigger to check that the drill is 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 its bearings.

The SA76 provides quick and simple removal of all types of spot weld. Simply insert a 6.5mm or 8mm spot drill and set
the depth on the nose of the tool. This drill can even take a out a spot-weld, a panel at a time, without damaging the
panels below. Supplied with 6mm drill bit

4.3. DRILLING INSTRUCTIONS.
p p
WARNING! Ensure you wear approved safety goggles and any other safety item required for the job.
Remove the hexagonal key wrench before using the drill. Also ensure that all other safety requirements
are followed.
3 Ensure the workpiece is secured and that neither plate is free to move as the drill bit rotates.
Note: Numbers in brackets refer to Item Numbers in the parts list.
4.3.1. Set the required cutting depth by rotating the adjustment attachment (42). The cutting depth is INCREASED
by rotating the adjustment attachment in the direction of the arrow shown in fig.3.
4.3.1. Connect drill to air supply.
4.3.2. Hold tool firmly and place the support over the weld to be drilled.
4.3.3. Depress the trigger to start drill. Apply pressure to the tool to move the drill bit into the weld
applying only enough pressure to keep the bit cutting.
4.3.4. 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.
4.3.5. For hard smooth surfaces use a centre punch to mark desired hole location. This will prevent bit from
slipping as you start to drill.
4.3.6. Adjust the cutting depth as necessary for the first weld. Once set the drill can take out a spot-weld, a panel
at a time without damaging the panels below.
p p
WARNING! Be prepared for drill binding. When this situation occurs 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.
4.3.7. If the bit jams in the work piece or if the drill stalls, release the trigger switch immediately. Remove
the bit from the work piece and determine the reason for jamming.
