INTRODUCTION & SPECIFICATION
Sealey’s Generation or G3 series of air tools represents some of the best design innovations in air tools of recent date. The tools feature contoured, soft-grip handles
and housings which help reduce the effects of vibration and chill – major contributors to circulatory and nerve problems such as white finger. The tools also include
exhaust systems designed to reduce noise levels by baffling the noise or directing it away from the operator’s environment. Most of the tools include integral and
adjustable air control valves for precise control of output. The air wrenches are, pound for pound, amongst the most powerful machines we have seen in the market
and the materials and manufacturing techniques used in the production of all the G3 series will ensure long and reliable service.

AIR SUPPLY
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 p WARNING! 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).

- Page 2 WARNING! Disconnect the hammer from the air supply before changing chisels, servicing or performing any maintenance. 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.
