Mounting/Removing Buckets
ALWAYS
wear protective goggles, helmets, gloves,
steel-toed shoes, etc.
DO NOT
service the bucket while the engine is
running.
DO NOT
stand behind the bucket when removing the
pins.
DO NOT
use your hands or fingers to align the bucket
and dipper arm holes.
ALWAYS
verify the bucket is safely locked before
starting the engine and resuming operation.
Removing A Bucket
1. Lower the bucket to the ground with the flat side
facing down (1, Figure 3-35).
2. Stop the engine.
3. Remove the two lynch pins (2A and 2B, Figure 3-
35).
WARNING
•
DO NOT use a hammer directly on a
securing pin to loosen it. The pounding
may cause splintering, which may lead
to serious injury.
•
The bucket can crush hands or feet. DO
NOT use your hands or feet as
substitutes for the correct equipment.
IMPORTANT
Place the bucket against the ground with
minimum pressure. More pressure in-
creases resistance, which will make it more
difficult to remove the pins.
