e.Store the tool when it is idle out of reach of children and other un- trained persons. A tool is dangerous in the hands of untrained users.

f.Maintain the tool with care. A properly maintained tool is easier to control.

g.Check for misalignment or bind- ing of moving parts, breakage of parts, and any other condition that affects the tool’s operation. If dam- aged, have the tool serviced before using. Many accidents are caused by poorly maintained tools. There is a risk of bursting if the tool is damaged.

h.Use only accessories that are identified by the manufacturer for the specific tool model. Use of an accessory not intended for use with the specific tool model, increases the risk of injury to persons.

b.When servicing a tool, use only identical replacement parts. Use only authorized parts.

c.Use only the lubricants supplied with the tool or specified by the manufacturer.

cause bursting, abnormal operation, breakage of the tool or serious injury to persons. Use only clean, dry,

regulated compressed air at the rated pressure or within the rated pressure range as marked on the tool. Always verify prior to using the tool that the air source has been adjusted to the rated air pressure or within the rated air-pressure range.

b.Never use oxygen, carbon dioxide, combustible gases or any bottled gas as an air source for the tool. Such gases are capable of explosion and serious injury to persons.
