stand on the ladder at the rear of the machine, you can check the reading on the
weigh box against your known weight; this may require assistance.
6. With the tractor running, check that the VFC-door opens fully and closes completely.
Similarly, check the movement of the feed-out tray. Engage the PTO and check the
turning of the paddles. The initial turning of the paddle rubbers against the side of the
KEENAN MechFiber diet feeder will generate noise, but this will decrease as the
paddle rubbers become more pliable.
As a general rule, the engine speed during loading should be as low as possible without
the risk of stalling the tractor. See the loading and mixing procedure guidelines.
Note:
A: The design life of hydraulic hoses is subject to the level of wear and tear/usage, as well
as to factors like harsh climate. It is recommended that they be reviewed periodically (i.e.,
yearly) and should typically be replaced after ten years of operation, as is necessary.
B: The maximum oil pressure of the hydraulic system is 3,000 psi.
C: If there is a
valve chest fit to the MechFiber machine, it is very important to connect the
valve chest hydraulic feed and return pipes correctly. The return pipe is not designed to
handle the hydraulic pressure normally experienced in the valve chest feed pipe, so seals
and/or the valve chest itself may be damaged if oil flows in the wrong direction through the
chest. Typically, the hydraulic return pipe on the valve chest is fit with a one-way flow valve
to prevent oil from being fed to the valve chest in the wrong direction. This is identifiable as
a steel connection on the end of the pipe with an arrow stamped on its side to indicate the
direction of the oil flow through it. Oil flows into the valve chest through holes marked P
(pressure) and out through holes marked T (tank). See Figure 5 below.
(The valve chest is set up for open-centre hydraulics. If the tractor has an alternative
hydraulic system [other than open-centre], contact the tractor agent. To alter closed-centre
hydraulics, there is a plug available on request from KEENAN Service that can be fitted to
the spool valve block.)
