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�
CLUTCH
The 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 ADJUSTMENT
Disable 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 BOLT
The 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 BEARING
Wheel 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�
ENGINE
Check oil daily and add oil as prescribed in the engine owner’s manual�
