Operating
h Avoid working in extremely hard materials e.g. granite and reinforcing iron
(reinforcement bar) which would cause substantial vibrations and excessive wear
on the pick hammer.
h Check regularly that the machine is well lubricated. The chuck and insertion tool
shank must always be covered by a film of oil.
Maintenance
Regular maintenance is a prerequisite for machine safety. Replace damaged and
worn components in good time.
Check the machine and insertion tool for wear and damage at regular intervals. Do
not use a very worn or damaged insertion tool.
When cleaning mechanical parts with a solvent, make sure that you comply with
current health and safety regulations and ensure that there is sufficient ventilation.
Daily maintenance, regular checking of wearing parts and carrying out repairs in
good time prevents breakdowns and increases the service life of the machine.
h Make sure that no foreign matter enters the machine.
h Always hose down and wipe clean the pick hammer after use.
Once a shift (after 8 hours of operation)
h Check the wear in the chuck bushing. If the wear limit has been exceeded, the
insertion tool shank will wear more quickly, or become deformed. This will lead
to stoppages and increased insertion tool consumption.
h Check the hoses, couplings and controls for leakage and damage.
h Every day before using the pick hammer, blow out the air hose to clear it from
accumulated dirt and moisture.
h Drain the water separator (if one is used).
Once a week (after 40 hours of operation)
Carry out a basic check of all functions of the equipment.
Once a month (after 200 hours of operation)
h Send the pick hammer to a workshop for inspection. The local operating
conditions will determine whether or not this is a suitable interval for overhauling
the machine.
h Clean out the water separator (if one is used).
Selection of spare parts
Use only genuine parts for replacement, to ensure stable performance. Never
use pattern parts, which not only have a short working life but also cause
consequential damage to other parts, due to differing measurements and methods
of manufacturing.
