SAFETY PRECAUTIONS
MAGMASTER 65/165
AN IMPORTANT MESSAGE FOR OWNERS & OPERATORS OF C-Dax
ATTACHMENTS/ACCESSORIES
Be warned of the dangers of loading your ATV or other vehicle in excess of its carrying capacity. It is
important to understand that any loads or attachments whether fastened to or placed on a vehicle or ATV will
alter the stability or handling characteristics of that vehicle or ATV.
Spray tanks or other equipment must be filled only to a level where the gross weight is within the load limit of
the ATV or other vehicle.
Safety is a primary concern in the design, manufacture, sale, and use of spray tanks and other equipment.
As manufacturers of spray tanks and other equipment we want to confirm to you, our customers, our
concern for safety. We take this opportunity to remind you about the simple, basic and common sense rules
of safety when using spray tanks and other equipment. Failure to follow these rules can result in severe
injury or death to operators and bystanders.
It is essential that everyone involved in the assembly, operation, transport, maintenance and storage of this
equipment be aware, concerned, prudent and properly trained in safety.
This also applies to equipment that is loaned or rented to someone who has not read the owner’s manual
and is not familiar with the operation of application equipment.
•NEVER EXCEED THE LOAD LIMIT CAPACITY OF THE ATV OR OTHER VEHICLE.
•ALL ATV AND TRAILED EQUIPMENT TYRES SHOULD BE INFLATED TO MANUFACTURERS
RECOMMENDED OPERATING PRESSURES.
•PLEASE NOTE THAT FILLING THE SPRAY TANK OR OTHER EQUIPMENT COMPLETELY AND OR
THE ATTACHMENT OF ADDITIONAL EQUIPMENT TO THE ATV MAY EXCEED THE ATV’S
MAXIMUM LOAD CAPACITY AND IT IS NOT RECOMMENDED TO EXCEED MANUFACTURERS
GUIDELINES
•CARGO SHOULD BE PROPERLY DISTRIBUTED AND SECURELY ATTACHED.
•REDUCE SPEED WHEN CARRYING CARGO OR PULLING A TRAILER OR TRAILED APPLICATION
EQUIPMENT AND ALLOW GREATER DISTANCE FOR BRAKING.
•NEVER ALLOW ANYONE TO RIDE ON YOUR SPRAYER OR OTHER EQUIPMENT.
•ALWAYS FOLLOW THE INSTRUCTIONS IN THE OWNER’S VEHICLE MANUAL FOR CARRYING
CARGO OR PULLING A TRAILER.
•PROPER MAINTENANCE IN LINE WITH MANUFACTURER’S RECOMMENDED MAINTENANCE
PROCEDURES IS ESSENTIAL.
•BEFORE APPLYING CHEMICALS, READ THE LABEL OF THE CHEMICAL MANUFACTURER OR
SUPPLIER FOR PERSONAL PROTECTIVE EQUIPMENT AND OPERATE AS RECOMMENDED.
•THE SAFETY OF ALL CHEMICALS USED IN AGRICULTURE IS UNDER THE JURISDICTION OF A
GOVERNMENT AGENCY, IE N.Z. MINISTRY FOR THE ENVIRONMENT; USA ENVIRONMENTAL
PROTECTION AGENCY. FURTHER LOCAL GOVERNMENT OR STATE LAWS MAY APPLY.

WARNING
Magnesium Oxide will set hard if exposed to air, it is of utmost importance that the
spreader be cleaned of all product even if stored for a short time. Load the spreader only
with the amount required to be spread and clean all traces of product from the machine
after use.

INTRODUCTION
Congratulations. You have just purchased an advanced spreader from C-Dax Ltd. C-Dax Ltd is committed to
providing you, the farmer, with quality applicating systems.
DESCRIPTION
The C-Dax MagMaster is a ground-driven spreader designed specifically for the application of powdered
Magnesium Oxide, available in 2 size options, 65L or 165L. The uniquely designed translucent non-corrosive
polyethylene hopper is specially profiled for good product flow, ease of filling and ensuring almost all product
is emptied. The distinctive polyethylene shroud guides powder away from the frame, shaft and gearbox
assembly. A high-quality stainless steel agitator and shutter ensure even flow of product to the spinner. A
unique spinner design ensures optimal spread of fine powders such as Magnesium Oxide. The heavy-duty
galvanised frame is fitted with turf tyres as standard equipment. The drive train uses high quality steel and a
double sealed self-aligning bearing and heavy-duty gearbox for maximum durability. While seated, the
operator has access to the control handle which controls the opening and closing of the shutter. The
supplied pin is placed through the axle shaft which engages the gearbox and this rotates the spinner.

OPERATION
The product to be spread is placed in the hopper. When the spreader is towed forward, the right hand wheel
drives through the pin clutch and gearbox to turn the spinner in a clockwise direction. When the control
handle is pulled forward, the shutter at the bottom of the hopper rotates to an open position. The size of the
opening is set by the adjustable stop pin, which locates into one of five pre-set positions.
An extension of the spinner boss is connected to a stainless steel agitator arm inside the bottom of the
hopper. This agitator ensures that product flows continuously out of the hopper to the spinning disk.
After calibration, fill the hopper to the required level and commence spreading. Do not overfill your hopper;
the maximum permissible payload is 40Kg. To prevent damage to product, disconnect the axle drive pin to
the gearbox until spreading is to be commenced.
To prevent the shutter from opening during travel to the paddock, move the adjustable stop pin to the rear-
most hole. This will lock the control handle in place and keep the shutter closed. See following diagram.
Adjustable stop pin shown in rear-most hole.
ASSEMBLY
1. Slide the drawbar into the frame and secure using 1 x M12x65 bolt
and Nyloc nut.
2. Slide the Control handle down between the 2 indicator brackets
and fit in place with 1x M10x50 bolt and Nyloc nut, fit 10mm
washer between the arm and the bracket welded to the main
frame.
3. Find the shutter arm. Attach this arm to the control handle and
shutter as shown to the right.
NB: Keep area around the handle and indicator bracket clean and
lubricated after every use.

CALIBRATION
Magnesium Oxide powder is applied at a rate determined by the number of cows to be treated. When
spreading this product, calculate the weight of powder to be applied and apply this amount with the
adjustment stop pin in position 1-5. Use the table below to work out which setting is most appropriate.

OPERATING THE SPREADER
When the spreader has been correctly calibrated, the hopper may be filled to the required level and
spreading commenced.
To reduce agitator damage to product and to ensure that product is not forced past the agitator shaft when
towing the spreader to the area to be treated, the drive to the gearbox should be disconnected by removing
the pin from the drive axle.
WARNING
To prevent damage to the spreader do not tow the spreader at speeds in
excess of 15 Kph during spreading or transit.
To prevent inadvertent operation of the shutter while the spreader is in transit it is recommended that the
adjustable stop pin be moved to the rear-most hole.
To prevent the shutter from vibrating closed when the spreader is operated over rough ground, the control
handle friction may be increased by tightening the two adjustment nuts at either end of the index plate.
WARNING
Due to the nature of Magnesium Oxide it is not recommended that the spreader be filled
with product if the spreader is to be towed a large distance to the paddock, as the product
will pack down and could potentially damage the agitator.
