A Lifting shackle B Decal
3. Attach lifting chains to the shackle. Keep the chain length as short as possible, to prevent swinging. Always
use lifting tackle which is strong enough and in good condition. Check the load weight before choosing
the lifting chains.
4. Attach a handline to the load. Make sure the person holding the handline stands clear of the load and
machine.
5. Test the load by lifting it then slowly manoeuvring it across the ground with the excavator controls. Lower
the load to the ground if you feel any instability of the load or the machine. When you are using the dipper
movement to lift, always lift by moving the dipper away from you, as shown, not towards you. This is because
hose burst protection valves (if installed) are provided only on the 'dipper-in' side.
Distance: 25–50mm

Digging
General
WARNING Do not use pedals which are not locked in position as foot rests.
Notice: When carrying out deep digging it is advisable to have the super structure swung in line with the
chassis. It is possible that part of the dig end may contact the machine. Take extra care when digging to
avoid damaging the machine.
Notice: Do not excavate on hard or rocky ground with the boom positioned diagonally across the
undercarriage. The resulting rocking motion could cause damage to the track gearbox sprockets and tracks.
