Slewing
!!
WARNING
When using the boom and dipper fully extended, take the
following precautions, otherwise the machine could get
damaged or become unstable and a danger to you and
other people.
Make sure you do not exceed the working capacity of
the boom at maximum reach.
Swing the boom slowly to prevent any chance of the
machine becoming unstable. For the same reason avoid
dumping downhill if possible.

!!
CAUTION
Do not excavate on hard or rocky ground with the boom
set diagonally across the undercarriage. This induces a
rocking motion that can cause damage to the track
gearbox sprockets and tracks.
HOP37
Before slewing the cab, ensure that the slew lock is
switched off (see Facia Panel).
Slew Left

WARNING
Before operating the excavator controls always check to
see which control pattern has been selected. Operate the
machine slowly until you are familiar with the pattern
selected. If the pattern selection indicator lamp is not
illuminated, DO NOT operate the machine until any faults
have been rectified.
