INSPECTIONS AND ADJUSTMENTS
Always stop mixer and lock out the power before servicing, repairing or cleaning the machine.
If work must be done inside the mixer, put a protective cover over the auger knives to avoid injury. The hopper
floor and fighting may be slippery. Use caution when stepping on or standing inside the machine.
Use safe shop procedures and exercise caution when working on the mixer!
INSPECT AND ADJUST...
...Roller Chain Tighteners so they will apply sufficient spring tension to keep roller chains running smoothly. As a
general rule the thickness of a nickel should fit between the spring coils. The chain will form grooves in the tightener
blocks. These grooves help to keep the chains in proper alignment and the blocks need not be turned unless the
roller portion of the chain has worn into the block.
...Roller Chains for wear, proper alignment and tension. Adjust or replace if necessary. Roller chain connector
links, which pass over polyethylene tightener blocks, must be installed with legs of the cotter pins trailing to the
direction of rotation.
...Safety Decals for legibility. If any safety decals are removed, obstructed, or otherwise not understandable, they
should be replaced immediately. Keep all decals clean - see SAFETY DECALS in the SAFETY section for more
information.
...Safety Shields to be sure all shields are in place and functioning properly. Replace all damaged or missing
shields immediately - see Parts Manual for shield part numbers.
...Bolts and Set Screws after a few hours of use and each month thereafter. Tighten if necessary.
...Reel Cross Tubes so that they slide in freely when compressed against the spring; the spring pockets may
need occasional cleaning. This sliding action helps prevent jamming and avoids overloading of the driveline.
...Reel Wiper Tubes for the condition of the plastic wiper strips, which help material clean out of the reel hopper. If
the strips become bent backward, they can be unbolted and be reinstalled backward or replaced to improve clean
out.
...Knives for damage or wear.
Upper Auger Knives can be turned over for use of a new cutting edge and should be periodically sharpened
or replaced if they no longer sufficiently break up material.
Round Lower Auger Knives can be rotated several times before sharpening or replacement is required.
Bolt-on Scallop Knives are to be replaced when they are worn.
Small Knives on the flighting perimeter are to be welded in when replacement is necessary.
...Motor Fan Guard. The fan guard must be kept clean to allow sufficient air flow for proper motor cooling.
...Drive Belts for wear and hardness. Old belts will be brittle or hard and must be replaced. Pulley misalignment
often causes belt wear and this alignment should be checked when replacing any worn belt. Inspect pulleys for
wear or damage both on the grooves and on the shaft diameter. Clean and dry belts thoroughly before reassembly.
Tighten belts to a tension that will allow the belt to deflect 1/2” when a 10lb. force is applied in the middle of the belt
span. Belts should be kept clean, dry and oil free.
IMPORTANT: WHEN WELDING ON THIS UNIT: DO NOT allow the current to flow through the bearings, roller
chains, or scale weigh bars. Ground directly to the item being welded. ALWAYS disconnect weigh bar cords from
scale indicator before welding.
