Performing Maintenance - Farm Aid 500 Owner's Manual

PERFORMING MAINTENANCE:

Make sure there is plenty of ventilation. Never operate the engine of the towing
vehicle in a closed building. The exhaust fumes may cause asphyxiation.
Before working on the mixer/feeder, stop the towing vehicle, 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 a safety support and block the wheels. Never use a jack to support
the machine.
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.
SHEAR PIN:
The machine is equipped with a 1/4" sized bolt as a shear pin to limit the torque input by
shearing if the peak torque is exceeded. This protects the chains, the spiral and,
potentially, the mixer box.
Bolts come in 4 levels of strength or hardness;
Grade 0- no marks on the top of the head (Weakest)
Grade 5- three marks on the head
Grade 8- 5 marks on the head
Socket head screw- the head is cylindrical with a hex shaped pocket (Strongest)
A 1,000 RPM machine should have a grade 5 bolt, nothing stronger.
A 540 RPM machine should have a grade 8 bolt. A Socket head screw may be used.
