6.7 Check the HCMB pump oil-level (iH600/iH1000 only)
WARNING
Do not remove the oil filler-plug while the pump is operating. If you do, hot
oil may be ejected from the pump.
WARNING
The majority of synthetic oils/grease can cause inflammation of the skin
(dermatitis). Safety precautions must be taken to prevent prolonged skin
contact with these substances. Use of suitable protective gloves and clothing
along with respirator is recommended if contact with substances is
anticipated.
CAUTION
Do not check the oil-level when the iH system is operating. The correct oil-level may not be
shown when the pump is operating.
CAUTION
Ensure that the oil-level in the HCMB pump is correct. If the pump oil-level is incorrect,
pump performance may be affected and the pump may be damaged.
Note: If there is a significant loss of oil from the pump, the shaft-seals may have failed. You cannot
replace the shaft-seal. Contact your supplier or a BOC Edwards Service Centre for advice.
Use the following procedure to check the oil-level.
1. Shut down the iH system (refer to Section 5.10) and allow it to cool.
2. Remove the right-hand side enclosure panel from the iH system: refer to Section 3.4.
