Hydraulic Unit Adjustment - Nautilus EVO S9AA Owner's Manual

Hydraulic Unit Adjustment

Some units use hydraulic shocks in the seat. The hydraulic unit only needs adjustment if the seat will
not stay in position. Refer to the unit diagram for the correct part number if replacement is neces-
sary.
Adjustment procedure:
1. Remove CLEVIS and COTTER PINS. Remove CIRCULAR COTTER
PINS by lifting up the wire that crosses over straight end of
pin. Save all pins.
2. Use a flat blade screwdriver to gently unsnap ADJ. CABLE from
LEVER. Be careful not to break cable fitting.
3. Remove hydraulic unit from machine, loosen ADJ. HEX NUT by
backing it down the rod. Hold LEVER MECHANISM and twist
shaft until there is free play in lever.
4. Hold LEVER MECHANISM and twist shaft until LEVER free play
is gone, then back off 1/8 turn. Tighten NUT against LEVER
MECHANISM. The NUT must be properly tightened to keep
hydraulic unit in adjustment.
5. Twist shaft slightly to realign the top and bottom clevis pin
holes.
6. Use pliers to snap and lock the CABLE on to the LEVER MECH-
ANISM.
7. Reposition the hydraulic unit on machine and insert CLEVIS
and COTTER PINS. The circular COTTER PINS can be pushed
into holes.
