OPERATION
OPERATING TECHNIQUES & PRECAUTIONS
DO NOT USE THE HAMMER
TOOL AS A PRY BAR
Excessive prying can cause premature
bushing wear and tool or tie rod
breakage. When hammering materials
that allow the tool to penetrate before
breaking, move the hammer slightly
fore and aft to create a cone-shaped
hole. The vented hole allows trapped
dust and heat to escape, increases the
tool penetration rate into the material,
and prevents overheating the tool tip.
DO NOT HAMMER CONTINU-
OUSLY IN THE SAME
POSITION FOR MORE THAN
30 SECONDS
If the tool cannot break or penetrate
into the material after hammering in
the same position for 30 seconds,
change the working location.
Hammering in the same position for a
long time will reduce the working
efficiency, increase the hydraulic oil
temperature, overheat the tool tip and
accelerate tool wear.
ALWAYS WORK BY
BREAKING TO A FREE FACE
The material must have somewhere to
break. Start at an edge.
