Foreseen Use of the Tool
These tools are designed for the purpose of chipping, riveting and scaling of metals and stone. In general terms a reciprocating free piston in the cylinder of the tool imparts a blow to the chisel or working attachment. A list of suitable equipment to use with these tools can be provided by the manufacturer. Do not use these tools for any other purpose than that for which they were designed without consulting the manufacturer or the manufacturer’s authorised representative. Do not modify these tools for their use as a chipper etc. or for any other purpose without first agreeing any such modification with the manufacturer or the manufacturer’s authorised representative.
Work Stations
These tools should only be used as handheld, hand operated tools. It is always recom­mended that the tools are used when standing on a solid floor. It can be used in other positions but before any such use, the operator must be in a secure position having a firm grip and footing and be aware of a reaction force on the hand as result of the tool doing work.

Putting Into Service
Air Supply
Use a clean lubricated air supply that will give a measured air pressure at the tool of 90 p.s.i./6.3 bar when the tool is running with the trigger fully depressed. Use recommended hose size and length. It is recommended that the tool is connected to the air supply as shown in figure 1. Do not connect the tool to the air line system without incorporating an easy to reach and operate air shut off valve. The air supply should be lubricated. It is strongly recommended that an air filter, regulator, lubricator (FRL) is used as shown in Figure 1 as this will supply clean, lubricated air at the correct pressure to the tool. Details of such equipment can be obtained from your supplier. If such equipment is not used then the tool should be lubricated by shutting off the air supply to the tool, depressurising the line by pressing the trigger on the tool. Disconnect the air line and pour into the intake bushing a teaspoonful (5ml) of a suitable pneumatic motor lubricating

oil preferably incorporating a rust inhibitor. Reconnect tool to air supply and run tool slowly for a few seconds to allow air to circulate the oil. If tool is used frequently lubricate on daily basis and if tool starts to slow or lose power. It is recommended that the air pressure at the tool whilst the tool is running is 90 p.s.i./6.3 bar. The tool can run at lower and higher pressures with the maximum permitted working air pressure of 100 p.s.i./7.0 bar.
Operating
Connect tool to clean supply of compressed air at recommended pressure. Select chisel/attachment to perform the work task and ensure that the chisel retainer is securely fitted. Do not use tool without retainer fitted. The power of the tool may be controlled by the input air pressure. Always ensure that the working tool is in contact with the workpiece before pressing the trigger. Running the tool free will reduce tool life by placing unnecessary high loads on tool retainers and cylinders.
Dismantling & Assembly Instructions
Disconnect tool from air supply Grip handle (1) in a vice with soft jaws and unscrew either retainer spring (21) or beehive spring (22). Spring off exhaust cover (20) and remove stopper pin (19). This will allow cylinder (2) to be unscrewed from handle (1). Remove piston (3) from cylinder (2). The valve assembly comprising of valve box (5), valve (6), valve seat (8) and pin (7) can be removed from the end of the cylinder and separated, but carefully note the orientation of the parts to the cylinder (2) for reassembly. Drive out lever roller pin (15) and handle knock pin (16) and unscrew inlet bushing (10) and plug (14) to allow lever (18), assistant lever (17), valve stem(11), O-ring (12) and spring (13) to be removed from the handle (1). Do not remove throttle bush (9) from handle (1) unless a replacement is required.
Reassembly
Clean all parts and examine for wear. Replace any worn or damaged components with parts supplied by the manufacturer or an authorised representative. Coat all parts with a pneumatic tool lubricating oil, one preferably containing a rust inhibitor. Ensure correct location of valve parts to cylinder and tighten cylinder until the stopper pin (19) can be located in one of the slots in the handle (1) which mates with one of the holes in cylinder (2). Assemble all other parts in the reverse order.
12) Always shut off the air supply to the tool, and depress the trigger/lever etc. to exhaust air from the feed hose before fitting, adjusting or removing the working attachment.
13) Check hose and fittings regularly for wear. Replace if necessary. Do not carry the tool by its hose and ensure the hand is remote from the on/off control when carrying the tool with the air supply connected.
14) Take care against entanglement of moving parts of the tool with clothing, ties, hair, cleaning rags, etc. This will cause the body to be drawn towards the tool and can be very dangerous.
15) It is expected that users will adopt safe working practices and observe all relevant legal requirements when installing, using or maintaining the tool.
16) Do not install the tool unless an easily accessible and easily operable on/off valve is incorporated in the air supply.
17) Take care that the tool exhaust air does not cause a problem or blows on another person.
18) Never lay a tool down unless the working attachment has stopped moving.
19) Never point a tool at any person.
20) Use only suitable pneumatic tool lubricants. This is important as a safeguard against the “diesel effect” i.e. explosive mixtures firing.
21) Chisels worn/blunt at the cutting edge or shank should not be used as such conditions promote tool breakage, reduce efficiency and increase vibration. A chisel which breaks can cause injury by creating unexpected movement.
22) When chipping or scaling in potentially explosive atmospheres use spark resistant chisels usually made of beryllium copper. Consult the manufacturer of the tool standard chisels about sources of supply.
23) Do not store chisels etc. at freezing and below freezing temperatures. Freezing temperatures can make hardened-tool steels brittle which can cause breakage and lead to injury.
24) Do not start tool until steel/chisel/rivet snap are in contact with the working surface. Do not run tool unless retainer is fitted.
25) Always use tool with a whip hose as shown in fig 1.
26) Don’t over reach. Keep proper footing and balance at all times.
27) Do not force the tool but allow it to cut.
28) When possible secure work with clamps or vice so both hands are free to operate the tool.
29) Use only 0.401” diameter shank size chisels or adaptors.
30) Prolonged exposure to vibration may cause injury.
Safety Rules For A Percussive Air Hammer
1) Read all the instructions before using this tool. All operators must be fully trained in its use and aware of these safety rules.
2) Do not exceed the maximum working air pressure.
3) Use personal safety equipment.
4) Use only compressed air at the recommended conditions.
5) If the tool appears to malfunction remove from use immediately and arrange for service and repair.
6) If the tool is used with a balancer or other support device ensure that it is fixed securely.
7) Always keep hands away from the working attachment fitted to the tool.
8) The tool is not electrically insulated. Never use the tool if there is any chance of it coming into contact with live electricity.
9) Always when using the tool adopt a firm footing and/or position and grip the tool firmly to be able to counteract any forces or reaction forces that may be generated whilst using the tool.
10) Use only correct spare parts. Do not improvise or make temporary repairs.
11) Do not lock, tape, wire, etc. the on/off valve in the run position. The trigger/lever etc. must always be free to return to the 'off' position when it is released.
