Safety
The Hi-Spec MixMax diet feeder has been designed with many safety
features built in to its design but ultimately, safe operation and
maintenance is the responsibility of the operator.
Recognise Safety Information.
Please pay attention to these signs for your own safety
This is a safety alert symbol. When you see this symbol on your machine or in this manual be alert to
the potential for personal injury.
Follow the recommended guidelines for safe operating practice:
Understand signal words: - On machine safety signs, signal words give the level of the hazard.
Danger
Indicates an imminently hazardous situation which, if not avoided, will result in
death or serious injury.
Warning
Indicates a potentially more hazardous situation which, if not avoided, could
result in death or serious injury.
Caution
Indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury. You will find these signs located near specific hazards
on your machinery.
Safety signs should be maintained and replaced when necessary.
They can often become dirty, torn or unreadable due to dirt and wear and tear.
If you need a replacement sign or have lost your user manual, please contact your Hi-Spec

Safety checklist
Do’s
Always disconnect all power sources before carrying out any adjustment or maintenance.
Always check inside the mixer to make sure it is empty
Always check around the feeder making sure everything is in order, this will only take a
minute.
Provide training to new users. Study this manual. Like all farm machinery, the MixMax
feeder is a potentially dangerous machine when under the control of untrained personnel.
Exercise extreme care when loading feed and additive into the mixer
Always ensure guards and other safety devices are kept in good working order. Replace if
necessary
Keep clear of all moving parts.
Always connect the shear bolt end of the PTO shaft to the tractor
Always use shearbolts recommended to you by Hi-Spec Engineering.
Always keep all hydraulic hoses and electric cables clear from PTO shaft
Always apply handbrake before unhitching and park the Feeder in a level area.
Always use ladder for mixing inspection point, DO NOT climb up the side of the Feeder.
Remember to fold up ladder after each inspection
Always take extra precautions when using the machine on hilly or sloping ground.

MixMax Diet
Don’ts
XNever permit young persons or spectators to operate PTO driven equipment or stand
anywhere close by when the MixMax feeder is in operation.
XNever permit untrained personnel to operate the Feeder without reading this manual and or
receiving training
XNever operate machine without having all guards in place, they are there for your safety and
protection against serious injury and death
XNever remove guards while there is still power going into the machine, all power must be
off!
XNever put your hands past the guard in front of the teaser roller while there is power going
into the machine, turn the machine off and then assess the situation.
XNever enter the machine while in operation. The mixing chamber is extremely dangerous,
there is a risk of fatal injury if you enter the mixing chamber while components are moving,
never under any circumstance enter the mixing chamber. If you need to enter the mixing
chamber for maintenance, please see instructions in the maintenance section..
XNever wear loose clothing when operating machinery, if standing too close your clothing can
pull you into the machine. This is one of the most common causes of machinery users being
dragged into moving parts causing serious injury or death
XNever operate the Feeder if you think there could be large stones or foreign objects inside,
they could cause serious damage to your machine
XNever leave machine running when unattended.
XIf the machine should become blocked with a stone or foreign object, DO NOT attempt to
free the object while the machine is running.
XDo not climb into the machine using the ladder or control box at the front or rear of the
machine
XDo not stand on the ladder whilst the feeder is in transit, the vertical feeder should never be
used for the transport of people, animals or objects.

PTO Shaft Safety
The PTO shaft is a vital link in driving the machine. It is also a very dangerous piece of equipment,
therefore it is important to follow the manufacturer’s guidelines on maintenance and repair. These
guidelines are fixed to the PTO when new. They should be removed, read carefully and then stored
with this instruction manual for future reference. If the guidelines are missing from the PTO Shaft
please contact your Hi-Spec dealer for another copy.
The irregular shape and connection joints of a turning shaft can cause serious injury. The rotational
force of the shaft is the main hazard.
Do not wear loose fitting clothing or articles such as jewellery that might get caught in a turning PTO.
The rotation of the PTO is 540 rpm when mixing. Accidents can happen very fast therefore keep a
safe distance from the shaft when it is in use.
PTO Shafts account for most of tractor related
fatalities.
Make sure the shaft is guarded.
Replace the guards when they are
Damaged or missing.
Never use the machine with
Damaged or missing guards
In an emergency situation, take the PTO
Out of gear, stop the engine and set the brake.

Getting Started

MixMax Diet
Tractor Requirements
The horsepower needed to power a Diet Feeder depends on the size of the machine;
MixMax 10
MixMax 14
MixMax 16
MixMax 18
MixMax 24
60 hp
70 hp
85 hp
100 hp
125 hp
Hydraulic Requirements
On Feeders with a Spool valve fitted:
One single acting valve is required. Attach the pressure pipe (RED) to the tractor valve and the return
pipe (GREEN) to the tractor reservoir.
On Feeders with no Spool Valve Fitted:
Two double acting valves are required.
!! WARNING!!
On Feeders with a Spool Valve fitted
Before connecting the hydraulic system it is imperative to ascertain the type of hydraulic system on
your tractor (open or closed centre)
With an open centre system insert valve marked X1 into the side of the Spool Valve
With a closed centre system insert valve marked X2 into the side of the Spool Valve

MixMax Diet
Connecting Feeder to Tractor
1. Use a pickup hitch or a short drawbar.
2. Have the Feeder on a level area.
3. Adjust the height of the bolt on hitch to ensure the machine is level when attached to
tractor.
The following diagram shows four different height options

MixMax Diet
Fitting PTO Shaft
Turn the tractor to full lock to either the left or right to get the shortest point of the PTO
shaft.
Slide the PTO apart and fit the half with the shear bolt to the tractor and the other end to
the machine.
Lift the two parts of the PTO shaft up so that they are level with each other.
Mark 150 mm (6″) back from each other as shown in the diagram below.
Cut off the excess profile.

MixMax Diet
Road Transportation
Before bringing your machine onto a public road, it is important to check thoroughly that the
machine is following all of the appropriate guidelines.
Ensure brakes are connected and working correctly
Ensure lights are connected and working correctly
Ensure PTO is disengaged and electronic readout is switched off
Observe local maximum road speeds for this type of machine
Hi-Spec Engineering strongly recommend extreme care to be taken by the operator when
travelling on rough roads with a loaded Machine as shock loads will damage the
weighbars. Owners and/or operators do so at their own risk.
The operator must ensure that any other regulations regarding road use are adhered to.
Extreme care must be taken when negotiating acute bends with high speed tractors.

MixMax Diet
Emergency Breakaway Handbrake
The emergency breakaway handbrake should be connected to the tractor every time the diet feeder
is been used. It should be done using the wire rope provided. The wire rope should be attached to a
solid part of the tractor like the top link pin and not to a panel on the tractor.
The wire rope should be tight enough so it will work effectively if the diet feeder became detached
from the tractor but loose enough that the handbrake is not been applied during normal operation.
