CRAWLER LOOSENING PROCEDURES
ABOUT HANDLING OF GREASE CYLINDER
Grease cylinder is under high pressure. It is dangerous to loosen the grease nipple rapidly because high pressure
grease will spout and may cause severe personal injury. Loosen the grease nipple gradually with your face kept
away from the area around the grease nipple.
Do not loosen the grease nipple more than one turn because it can pop out due to the internal high pressure
grease.
