TOOL BREAKAGE

TEMPERATURE RELATED TOOL PROBLEMS

LOW TEMPERATURE
Metallic material becomes brittle in a low temperature environment and particularly
sensitive to impact stress.
PREVENTATIVE MEASURES
Warm the tool before starting to operate the hammer when temperature is below 32°F,
(0°C).
WARRANTY
NPK Warranty does not cover this type of failure.
EXCESSIVE SLANT HAMMERING
When constant slant hammering is performed while using boom downforce, the tool
may become deformed as shown in the picture below.
HIGH TEMPERATURE
When the tool is used in a high temperature environment, such as for slag removal from
a furnace, the tool may be deformed as shown in the picture below.
PREVENTATIVE MEASURES
Use compressed air to keep the tool cool enough not to deform.
WARRANTY
NPK Warranty does not cover this type of failure.
