2.7.3 Locking the Apron
To install the locking pins for the apron, first secure the machine as listed in the previous section.
Once the machine is secure then raise the apron all the way. This will go past the locking position
and the apron will need to be lowered slightly. It is advised to have an assistant indicate when the
locking holes have come into alignment. Once the locking holes are in alignment the safety pin
can be installed. Install the lynch pin on the inside of the bowl only after the rippers have been
locked out.
To aid in exchanging cutting edges, it is recommended that the scrapers
mouldboard be lifted up and then lowered on at least two heavy duty
workshop stands of rating 10 tonne or greater to allow access to the nuts
under the mouldboard. Stands or blocks should also be positioned under the
back of the rear frame and under the front cross beam so that no part of the
machine is supported by hydraulic cylinders. The hydraulic lines should be
disconnected from the tractor and the tractor locked out so that it cannot be
operated while maintenance staff are working on the scraper.
