MAINTENANCE Chain Brake If the chain brake does not work properly, remove the clutch cover and clean the chain brake components. Check wear on the brake band ( A ) and replace if worn or deformed. The band thickness should not be less than 0.024" (.60mm), or worn halfway through. Always keep the chain brake mechanism clean and lightly lubricate the linkage ( B ). Always test the chain brake performance after servic- ing or cleaning per the Operation - Chain Brake Sec- tion. Check and, if damaged, replace the chain catcher / safety stop ( C ). Oil Pump (automatic/adjustable) Flow adjustment is pre-set by the manufacturer.
Oil flow can be adjusted by the operator according to specific requirements by means of the special adjusting screw ( D ). Oil flow occurs only when the chain is moving. D C A B B 24 English
