blow off any water remaining on the RHGSE or towel dry.
7.2) General preventive maintenance
Keep the RHGSE relatively dry.

Do not impact the Rotatub, especially in cold operating conditions.
Do not leave water in the tub in conditions likely to freeze.

7.3) Clutch adjustment
The clutch has been preset at Zephyr to approximately 100 lbs.
If a high load is desired then make small clockwise adjustments until the empty RHGSE starts to lift.
When the RHGSE starts to lift, the load in the wire rope is approximately 580 lbs. To reduce the load,
turn the load adjuster counter clockwise. Check operation in the retract mode.
7.4) Clutch removal and replacement
It is only required to remove the clutch assembly when adjusting the head to tighten the
capstan drive chain.
Any adjustment between the upper and lower heads requires removing the load cell assembly.
Remove the (2) hex head bolts and unscrew the load adjuster completely. Then remove the cotter pin
from the load cell clevis pin and remove the entire load cell assembly.
If it is required to remove the clutch band then, unscrew the load adjuster completely. Remove the
cotter pin from the load cell clevis pin. Then carefully work the clutch band and load adjuster pin out
from under the load cell mounting plate.
If the clevis and through hole load cell are disassembled the load display will need to be readjusted. It
is not required to remove the load cell or the attachment bolt.
Use light grease on the pivot bolt and the load adjuster shaft.
