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).

p

WARNING!

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.
