OPERATING INSTRUCTIONS

Return to Table of Contents

The model 1200 Mixer is heavy-duty and capable of mixing materials to an ideal consistency in only minutes�It is suitable for all plaster, mortar, cementitious slurries, reproong materials, accoustic, roong coatings,gypsum mixes with sand, clay, vermiculite, perlite, magnesite, low and high viscosity liquids�

CLUTCHAlways verify the clutch is disengaged before starting the engine� Allow the engine to warm up beforeengaging the clutch�

MIXINGAdd all except 1-1/2 gallons of water� Engage the clutch to start rotating the paddles� Add all of the cement and let it mix into a soft, lump free, slurry� Gradually add the aggregate at about 1 cubic foot every 15 seconds� Add the remaining water desired to get the consistency desired�

CLEAN UPKeep the mixer as clean as possible as a clean and well maintained machine will give maximum years of service�

SEALS AND BEARINGSLubricate the bearings and shaft seals daily� Fill with waterproof grease until the grease starts to squeezeto the seals and retaining rings� This is often audible as pockets of air pop through the seals and retainingrings� Do not try to force grease through the seals as doing so can cause the seals to fail� Impropermaintenance will shorten the life of the seals, bearings, and paddle shaft�

OPERATING INSTRUCTIONS

Return to Table of Contents

SEAL REPLACEMENTIt is recommended to replace the bearings anytime these seals are replaced, as they are relatively inexpensive versus the cost of downtime and labor� The paddle shaft should be thoroughly inspected for grooves� Paddle shafts with a groove 1/8” or deeper should be replaced�

Disconnect the gearbox from the shaft coupler and remove the engine and gearbox from the engine compartment� Remove the bolts holding the drum’s pillow block bearings to the frame and remove the drum from the frame� Remove the paddles from the paddle shaft if the shaft is to be replaced� Remove the pillow black bearings from the shaft� Removing the ange mount bearing exposes the seal and grease ring assemblies� For seal installation, put a small amount of grease on the rubber seals so they will slip on the shaft� The seals are purposely undersized to allow wear� Assemble as indicated on the illustration� Completely ll the seal cavity with waterproof grease�

GEARBOX

Return to Table of Contents

The gearbox has two compartments separate from each other� The compartment closest to the engine is for the clutch assembly, and the compartment closest to the paddle shaft is for the speed reducing gears�

The clutch compartment uses a 30W engine oil every other month and change at least once per year� The gear reduction compartment uses a 90W gear lubricant� Check the level every other month and rell as necessary�

CLUTCHThe clutch is set from the factory to allow for some initial wear� Refer to the illustration and the following instructions to maintain the clutch for proper operation:

CLUTCH ADJUSTMENTDisable engine from being able to start�1� Disengage clutch�2� Remove inspection plate on the gearbox�3� Bump engine over until adjusting clip can be accessed�4� Loosen the lock screw and move the clip away form the 5� notches on the adjusting ring�Rotate adjusting ring one notch at a time until desired engaging 6� pressure is achieved� Proper pressure is indicated when it requires a smooth and rm force that will cause it to click into place� It should not be set too tight as some of the clutch parts can break� If you have to lean into it using your body weight to engage the clutch, it is too tight� To tighten the clutch, rotate the adjusting ring counter- clockwise or downward�Replace the adjusting clip and lock down by tightening the screw�7� Replace the inspection plate and seal with silicon or a new gasket�8� Rell clutch housing with oil�9�

SHEAR BOLTThe 1200 mixer has a shear pin at the output of the gearbox were it connects to the paddle shaft�If a serious jam occurs, the shear pin may break� It is a good idea to keep an extra shear pin on hand�

WHEEL BEARINGWheel bearings should be given the same care as if they were on a boat trailer or on a car receiver�Repack the adjust wheel bearing every six months�

ENGINECheck oil daily and add oil as prescribed in the engine owner’s manual�
