If the rotating mixing paddles appear to be losing rotational speed, it may be necessary to adjust the clutch. For optimum performance Multiquip recommends 35-55 lbs. applied pressure to the hand clutch lever. After the first initial operating hours (8) check the clutch for proper ensasment pressure.

Clutch Adjustment Procedure

CAUTION:

Always stop the engine, disconnect the spark plug or electrical power cord before attempting this procedure.

2.Drain the clutch compartment oil by removing the magnetic 3/8 plug located at the bottom of the Gear Reduction Assembly.

NOTE

The Gear Reduction Compartment consist of two compartments, a lower and upper.The lower compartment houses the clutch, the upper compartment contains the actual gear reduction. Remember each compartment requires a different type of lubricating oil.
