e. Store tool when idle and out
of reach of children and other
untrained persons. A tool is
dangerous in hands of untrained
users.
f. Maintain the tool with care. A
properly maintained tool is easier to
control.
g. Check for misalignment or binding
of moving parts, breakage of
parts, and any other condition
that affects the tool’s operation. If
damaged, have 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.
Service
a. Tool service must be performed
only by qualified repair personnel.
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.
Air source
a. Never connect to an air
source that is capable of
exceeding 90 psi. Over
pressurizing the tool may
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.
