Transcript of ROC203 CE Service Schedules
CAUTION
Before each shift commences, carry out the “Daily checks” incl.“Extra safety check” as described in the Operating InstructionsNo. AIB 181 00 10For rock drills see Maintenance Schedule
CAUTION
Repairs to the crawler shall only be carried out by experiencedservice personnel which is familiar with the rig design. Also, anywelding work necessary may only be carried out by approvedwelders (authorized acc. to EN 287 part 1). After repair, thecrawler is to be inspected and approved by qualified engineersbefore being put back into service.
NOTEl = Check points and maintenance measuresm = Lubrication, oil change etc.

Recommended hydraulic oils and lubricants
Lubricating point Recommendation
Hydraulic oil tank l Use mineral-based hydraulic oils with good anti-wear, anti-rust, anti-oxidation and foam inhibitingproperties and with good air and water separation characteristics. Choose an oil with viscositygrade (VG) and viscosity index (VI) in accordance with the table below. An oil with a high viscosityindex is less sensitive to the effects of temperature:
Hydraulic oil temperature in tank °C (°F) Viscosity ViscosityNormal operating temp. Min. starting temp. Max. temp grade VG index VI
2(viscosity 25-50 mm (cST)) (viscosity min. (ISO 3448)/s21000 mm /s (cST))
+ 45 to + 60 (113 to 140) -5 (23) 75 (167) ISO VG 68 min. 100+ 35 to + 50 (95 to 122) -10 (14) 65 (149) ISO VG 46 min. 100+ 25 to + 40 (77 to 104) -15 (5) 55 (131) ISO VG 32 min. 100+ 10 to + 25 (50 to 77) -25 (13) 45 (113) ISO VG 15 min. 100NB: When operating in extremely low temperature, installation of additional heating equipment is
recommended. If the oil temperature exceeds +60 °C (140 °F) during long periods, a tropicaloil cooler should be installed.
