3.1 Air Supply
Recommended hook-up procedure is shown in fig 1.
3.1.1 Ensure tool air valve (or trigger) is in "off" position before connecting to the air supply.
3.1.2 You will require an air pressure of 90psi, and an air flow according to specification.
3.1.3 pWARNING! Ensure the air supply is clean and does not exceed 90psi 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.
3.1.4 Drain the compressor air tank daily. Water in the air line will damage the tool.
3.1.5 Clean compressor air inlet filter weekly.
3.1.6 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.
3.1.7 Keep hose away from heat, oil and sharp edges. Check hose 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 tool.
To overcome this, connect a leader hose to the tool. A quick change coupling may then be used to connect the leader hose to the air line recoil hose. See
fig 1 & 2 (overleaf).
Risk of Hand Arm Vibration Injury
Long Stroke G3 Air Hammer Model No. GSA11 when operated in accordance with these instructions and tested in accordance with EN 28662-2: 1994 results in
the following vibration emission declared in accordance with
BS EN12096: 1996.
Measured vibration emission value: . . . . . . . . . . .20m/s² Uncertainty: . . . . . . .8m/s²
These values are suitable for comparison with emission levels of other tools that have been subject to the same test.
This tool may cause hand-arm vibration syndrome if its use is inadequately managed.
Recommended Measures to reduce risk of hand-arm vibration syndrome:
This tool should not be used by an individual regularly for more than 15.3 minutes in any 8 hour period.
This duration of use should be reduced if the individual is exposed to hand-arm vibration from other sources.

Note: Numbers in brackets refer to item numbers in the parts list.
The air hammer is designed primarily for use on vehicle bodywork. We do not recommend any other use. Ensure you read, understand and follow the safety
instructions in Section 1.
4.1 Attach the retaining spring (21) by screwing it onto the cylinder (18).
4.2 Insert the chisel using the hooked end of the spring to hold the chisel in place.
4.3 Attached the tool to the air supply (see Section 3).
4.4 To operate the hammer, squeeze the trigger (11).
pWARNING! Disconnect the hammer from the air supply before changing chisels, servicing or performing any maintenance.
5.1 Keep the hammer oiled for optimum performance. Lubricate with a good grade of air tool oil such as Sealey ATO/500 or ATO/1000. If there is no oiler in
the air system then a teaspoon of oil can be poured into the air inlet of the hammer, or into the hose at the nearest connection to the air supply. Then run
the hammer for a short time.
Note: The following external factors may cause loss of power and effect hammer performance:
The air supply: reduced compressor output, excessive drain on the air line, moisture or restrictions in air pipes or the use of hose connectors having too small a bore.
Correct as necessary.
The hammer: grit or gum deposits in the tool. Correct by cleaning the air strainer and flushing out the tool with gum solvent oil or an equal mixture of SAE No.10
oil and kerosene. If, despite taking action as above, the tool function is still impaired, contact your local Sealey service agent.
