How to Remove Slinging Loop
WARNING
q
If the slinging loop is caught on any part of the bucket
(tooth, lip shroud, wear cap, adapter, side shroud),
remove it. If digging operations are carried out without
removing the slinging loop, there is danger that the
slinging loop may break and pieces may fly around.
q
It is dangerous if the machine begins to move while
the slinging loop is being removed. Hold the work
equipment in a stable posture, stop the engine and
make sure to put the lock lever to the LOCK position.
q
When removing the slinging loop, wear protective
tools like safety glasses. There is a danger that metal
pieces of the broken slinging loop are sent flying
around.
q
Never hit the tooth against a boulder for the purpose of
removing the slinging loop.
There is the danger that the broken slinging loop will
be sent flying around in pieces, causing a personal
injury.
NOTICE
If the machine is operated without the slinging loop being removed, the following problems will possibly
arise.
When the work equipment is pulled back, the slinging loop at the tip of the tooth interferes with the boom.
The cracks caused when the slinging loop breaks may extend to various parts of the main body (tooth, lip
shroud, wear cap, adapter, side shroud) and damage the main body of the parts.
The slinging loop may break during the digging work and its broken pieces are mixed in the sand, earth
and stones to be loaded.
Be sure to remove the slinging loop in the following steps.
1. Put block (3) under the bottom of the bucket and stop the
engine.
