This machine can be lubricated through grease fittings without
using the auto lubrication device by following the procedure
below.
NOTE: When greasing the backhoe front attachment, fully ex-
tend the arm cylinder, lower the boom until the bucket
comes in contact with the ground, and adjust the
bucket cylinder stroke so that the bucket bottom is ap-
proximately upright to the ground as illustrated to the
right. This position allows easy access to all greasing
points.
