GREASING INNER AND OUTER DRAFT BEAM
PIVOT POINTS
Locate the grease zerks on the inner and outer draft beam pivot bosses. Inject
Lithium-Complex Extreme Pressure grease conforming to NLGI2-ISO 320
specifications into each zerk until grease protrudes from joints. Grease all pivots
daily or every 8 hours of service.
With the cutter head lowered, locate the
grease zerks on the linkage and pivot bosses.
Inject Lithium-Complex Extreme Pressure grease
conforming to NLGI2-ISO 320 specifications until
it protrudes from the ends. With the cutter head
in this position it is also possible to grease the
draft beam cylinder anchors and pins. Now
raise the cutter head to expose the remaining
zerks on the deck tilt linkages and on the other
end of the cylinder.
