2.4.3 Hydraulic Hose Replacement
Load, vibration, and other mechanical stresses place high demands on hydraulic hoses.
When replacing hydraulic hoses, check that they are replaced with hydraulic hoses:
• With the correct crimped couplings
• Of the correct quality class
• Of the correct dimensions
All pressurized hoses have pressed couplings and can therefore be purchased ready made
from Epiroc. Grades and dimensions of hoses are specified in the spare part catalog for
the machine in question. Also make sure that hose couplings are clean, not damaged and
properly tightened.
2.5 Welding
• All welding on the Rock Drill is forbidden.
2.6 Long Period of Storage
Action must be taken to protect the equipment from corrosion and storage damage if stor-
age expected to last longer than three months.
• Wash the equipment and thoroughly wipe it dry. Use compressed air to blow any col-
lections of water out of cavities and pockets.
• Store equipment on site with regulated temperature and ventilation. Recommended
storage environments maintain a temperature of 10-20 ºC and max 20–50% humidity.
• Apply corrosive protection compound to machined surfaces.
• Apply touch up paint to any scratches and damage on painted areas.
• Cover with plastic.
• Clean old grease away from lubrication points to prevent coke formation. Pump new
grease into the lubrication nipples. Ensure that you use the correct grease for each
point.
• Hoses and rubber parts can be packed in airtight plastic to reduce desiccation, but en-
sure that the components are dry before packing.
2.7 After Long Period of Storage
• Change lubricant and hydraulic oil where appropriate.
