PERFORMING MAINTENANCE:

Make sure there is plenty of ventilation. Never operate the engine in a closed
building. The exhaust fumes may cause asphyxiation.
Before working on the mixer/feeder, stop the truck, set the brakes, disengage the
PTO and all power drives, shut off the engine and remove the ignition keys.
Be certain all moving parts on attachments have come to a complete stop before
attempting to perform maintenance.
Always use the proper tools or equipment for the job at hand.
Never use your hands to locate hydraulic leaks on attachments. Use a small
piece of cardboard or wood. Hydraulic fluid escaping under pressure can
penetrate the skin. When disconnecting hydraulic lines, shut off hydraulic supply
and relieve all hydraulic pressure. Openings in the skin and minor cuts are
susceptible to infection from hydraulic fluid. If injured by escaping hydraulic fluid,
see a doctor at once. Gangrene can result. Without immediate treatment, serious
infection and reactions can occur.
Replace all shields and guards after servicing and before moving.
After servicing, be sure all tools, parts and service equipment are removed.
Do not allow grease or oil to build up on any step or platform.
Where replacement parts are necessary for periodic maintenance and servicing,
genuine factory replacement parts must be used to restore your equipment to
original specifications. Farm Aid Equipment will not claim responsibility for use of
unapproved parts and/or accessories and other damages as a result of their use.
If equipment has been altered in any way from original design, Farm Aid
Equipment does not accept any liability for injury or warranty.
A fire extinguisher and first aid kit should be kept readily accessible while
performing maintenance on this mixer/feeder.

CHAIN TENSION

The chains should be checked yearly. They should be adjusted so that the center of the
chain can be moved freely at the center of the span as listed below:
Front chain: 3/4"
Inside rear chain: 1"
Big rear chain: 2"

LUBRICATION

Every 120 hours:
1 nipple on the front side 3 pumps and the front center spiral zerk gets 6 pumps
3 nipples on the rear side 3 pumps and the single nipple on the other side 6 pumps

HYDRAULIC SYSTEM

The oil in the hydraulic system is 30 weight non-detergent oil. On the side of the
reservoir there is a level and temperature indicator. If the oil appears gray or milky it has
been contaminated with water and needs to be drained and replaced.
Daily check oil level and color
Annually replace the spin on oil filter
