Choosing The Correct Hammer
Mismatched - Small Hammer on Large Machine
Machine overpowers (weight) hammer may cause damage to hammer

Trang 32s DO NOT strike in one spot for
more than 15 seconds
s If object does not break, REPOSITION the hammer
» Creates a dust pocket under the point, dampening the impact effect and producing

Correct Working Methods
STOP the hammer BEFORE the material collapses DO NOT allow the hammer to fall through the broken material and blank fire
Frequent pin strokes (blank firing) will damage increase component wear and may hammer
STOP NOW!

Correct Working Methods
Do Not Use A Standard Hammer Underwater!
These models have optional porting provided for easy
conversion to underwater use
eCompressed air is required to keep penetrating the hydraulic system In salt water applications, special care must be taken to prevent corrosion

Trang 36Underwater Applications Air Flow Requirements
COMPRESSOR
Air compressor is fitted on the carrier
The air hose must be led along carriers boom to prevent hose breakage
The required air pressure and air flow depends on hammer model and on the wear
of tool bushings and tool
