Foreseen Use of the Tool

These tools are designed for the purpose of chipping and 

riveting 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 

this tool can be provided by the manufacturer. Do not use the 

tool for any other purpose than that for which it was designed 

without consulting the manufacturer or the manufacturer’s 

authorised representative.

Do not modify the tool for it’s 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.

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 

Work Stations

The tool should only be used as a handheld, hand operated tool.  

It is always recom-

mended that the tool 

is used when stand-

ing on a solid floor.  It 

can be used in other 

positions but before 

any such use, the op-

erator must be in a 

secure position hav-

ing a firm grip and 

footing and be aware 

of a reaction force on 

the hand as result of 

the tool doing work.
