ADJUSTING STABILIZER FOR USER PREFERENCE

Adjusting Type A Stabilizer Assembly for User Preference (FIGURE 13)

NOTE: Refer to STABILIZER INDENTIFICATION in the beginning of this section to determine correct sta- bilizer assembly.

1.While the user is in the wheelchair, measure the dis- tance between the bottom of the stabilizer wheel and the ground/floor.

NOTE: Measurement MUST be between 7/8 and 1-inch.

2.If the measurement taken in STEP 1 IS NOT between 7/8 and 1-inch, perform the following procedure:

A.Loosen the jam nut on the stabilizer cylinder rod and back the jamnut down until it is touching the adjustment nut.

B.Remove bottom bolt and locknut that secure bot- tom of the stabilizer cylinder to the stabilizer plates.

C.Perform one (1) of the following:

MEASUREMENT GREATER THAN 1-INCH - Turn the bottom of the stabilizer cylinder COUN-

TERCLOCKWISE.

MEASUREMENT LESS THAN 7/8-INCH - Turn the bottom of the stabilizer cylinder CLOCKWISE.

D.Line up mounting holes in stabilizer cylinder and the stabilizer plates and reinstall the bottom bolt.

E.Perform one (1) of the following:

DISTANCE IS BETWEEN 7/8 AND 1-INCH - Reinstall the locknut tighten securely.

DISTANCE IS NOT BETWEEN 7/8 AND 1-INCH - Repeat STEPS B-E until the measurement is between 7/8 and 1-inch.

F.Tighten the jamnut on the stabilizer cylinder.

Adjusting Type B Stabilizer Assembly for User Preference (FIGURE 14)

NOTE: Refer to STABILIZER INDENTIFICATION in the beginning of this section to determine correct sta- bilizer assembly.

1.While the user is in the wheelchair, measure the dis- tance between the bottom of the stabilizer wheel and the ground/floor.

NOTE: The distance between the bottom of the stabilizer wheel and the ground/floor is factory set at one (1) inch.

2.To increase obstacle climbing ability or stability per- form the following:

A.Loosen the jam nut on the stabilizer cylinder rod and back the jamnut down until it is touching the adjustment nut.

B.Remove bottom hex bolt and locknut that secure bottom of the stabilizer cylinder to the stabilizer plates.

C.Perform one (1) of the following:

Increase obstacle climbing ability - Turn the bottom of the stabilizer cylinder

COUNTERCLOCKWISE.

Increase stability - Turn the bottom of the stabi- lizer cylinder CLOCKWISE.

D.Line up mounting holes in stabilizer cylinder and the stabilizer plates and reinstall the bottom hex bolt.

E.Check performance of the wheelchair. Repeat STEPS A-D if necessary.

F.Tighten the jamnut on the stabilizer cylinder.
