Deck Actuator Adjustment; Brush Motor Carbon Brush Replacement - Kärcher WINDSOR Chariot 3 Operating Instructions Manual

Deck Actuator Adjustment

The actuator will need to be adjusted when replaced.
To adjust the actuator:
1. While holding the actuator barrel to prevent it from
spinning, apply power to the actuator such that it is
fully extended. Positive power to white wire, and
negative/ground to black. Limit switch within
actuator will prevent overtravel.
2. Turn barrel out one or more full turns to assure that
when it is retracted it will not bind against itself.
3. While holding actuator barrel to prevent it from
spinning, apply power to the actuator such that it is
fully retracted. Positive power to the black wire,
and negative/ground to white wire. Limit switch
within actuator will prevent overtravel.
4. With actuator fully retracted, turn barrel in until it
touches the base of the threaded shaft.
5. At the bottomed out position, turn the barrel out
one full turn.
6. Connect actuator to lift linkage. If holes in barrel do
not align with linkage brackets, turn barrel out only
enough for proper alignment.
7. Raise and lower brush deck. Ensure actuator
barrel does not bottom out.
