PRECAUTIONS FOR USING THE DOZER
1. When using the dozer blade as stabiliser.
Use the dozer blade in the same way as an outrigger. How-
ever, use it only on level ground so that uneven loads will not
be applied to the blade.
2. When using the dozer blade with the upper structure facing
the rear of the undercarriage, the steering wheel acts in the
opposite direction to normal travel.
3. Ensure that suspension lock system is fully free when
required for dozing operations. see "AUTOMATIC SUSPEN-
SION LOCK SWITCH (101)"
REMARK
Dozer blade is to be used only for stabilizing and light dozing.
