Safety Notes and Warnings
!Ensure the operator in charge of the weighing operation is an experienced stock
person who can maintain a high standard of animal welfare.
Ensure that there is sufficient space in the area designated for weighing to allow the
operator to work safely and efficiently.
The adjoining Race and Penning to the weigher should be of sufficient build for the
safety of both animals and operators.
Do not have any auxiliary hurdles or gates attached directly to the crate as this will
provide inaccurate readings. If hurdles are to be used these should be attached to
the posts provided which fit into the sockets on the weigh platform base.
!
!
Note: Check also the instruction leaflet provided by Salter Brecknell (Electronic weigh head
manufacturer) provided with this product for details on EMC compliance and declaration of
conformity.
Retain all instructions in a safe place for future reference.

Introduction and Intended Use
Ritchie weigh platforms models 327G (spring balance) and 327GE (electronic) were designed
for, and intended to be used by, the agricultural industry for the weighing of animals.
The unit has been designed to operate with the Ritchie Cattle handling Crate model numbers
300g, 339 and 339g.
However other makes of cattle handling crates may be fitted using the fastenings supplied and
fitted in accordance with our instructions.
The platform requires a ‘back weight’ of 350 - 500 kgs which is normally provided by the unladen
weight of a handling crate in order to zero the weigh head.
The platform may be used for other weighing purposes providing an alternative ‘back weight’ is
fitted. i.e. Heavy steel plate floor.
Note:- The platform does not conform to DTI certification and is illegal to be used for selling
by weight.
These weighers should only be used by an experienced stock person, who can maintain
a high standard of animal welfare.
Deviations from the intended use should not take place without the notice and approval
of David Ritchie (Implements) Ltd.

To operate:-
Do not have any auxiliary hurdles or gates
attached directly to the crate as this will
provide inaccurate readings. If hurdles are to
beused attach them to the two verticalposts

If using a Ritchie model 300g cattle crate it
will be necessary to shorten these posts to
10mm above the hurdle lug as shown, Fig 6.
Ensure the column carrying the weigh head
is in the vertical position.
Allow the animal to enter the handling crate
and settle.
To weigh, depress the foot pedal and hold
thepedal in the down positionwhen reading
the weight.
When weighing an animal is complete,
remove your foot from the foot pedal. When
the animal is released from the handling
crate, the cam will return to the ‘locked’
position on the foot pedal mechanism.
Togain access viathe sidedoors of theRitchie
