Figure 4: The Handy Depressor Button. Depress the button while turning clockwise to giveincreased damping forces.

Rebound adjustable, the adjustment is made with the shock fully extended.

Move the dust cover and the plastic or metal cover on the end of the damper body to expose the adjusting button (figure 3).
Hold the damper body securely in one hand near where the piston
rod emerges from the body or use a vise/clamp carefully only at the lower attachment only. With the damper fully extended, press and hold the adjuster button with one nger while turning the piston rod with your other hand.
The adjusting device has been provided with a number if clearly
distinguishable stops (clicks), each of which marks an adjustment
position for 26 series (zero + 2 clicks = 3 positions) and 30 series (zero + 3 clicks = 4 positions).
Prior to making a new adjustment, conrm if the damper is in the
zero position or has been adjusted previously by turning the piston rod to the left (counter clockwise) until the zero-stop is felt. DO NOT USE FORCE or adjuster damage may occur.
To increase rebound, turn the piston rod one or more clicks to the right (clockwise), and release the adjusting button.
Be sure the adjusting button fully springs back into position. As long as the button is depressed, do not turn the piston rod further; otherwise correct adjustment will be disturbed. As soon as the button has made its complete return, the piston rod may be turned freely. The damper can now be refitted.

Clockwise: Firmer
Counter Clockwise: Softer

Adjustment Procedure 80, 82, 86, 87, 88, 90, 8040, 8240 Series

Figure 1: Fully collapse the shock absorber, at the same time turning the dust cap or piston rod slowly to the left (counterclockwise), until it is felt that the cams of the adjustment nut engage in the recesses of the foot valve assembly.

Figure 2: Keeping the shock absorber collapsed, make 1 half turn (180 degrees) to the right (clockwise). In case of prior adjustment add the number of half the turns previously found. The total range is about 4-5 half turns, we suggest the MAX crank of 4.

Figure 3: Pull the shock absorber out vertically without turning for at least 1 cm to disengage the adjusting mechanism. The dust cap or piston rod may now be turned freely.

Rebound Adjustment Procedure

Remove the shock absorber from the vehicle and hold it vertically
with the lower eye or pin attached in a vise. Use clamp plates to prevent damage.
Fully collapse the shock absorber, at the same time turning the dust cap or piston rod slowly to the left (counterclockwise), until it is felt that the cams of the adjustment nut engage in the recesses of the foot valve assembly (Figure 1).

*Some shock absorbers include a bump rubber concealed under the dust cover and it must be removed prior to adjusting.
The damper may have already been adjusted. Therefore check
whether the shock absorber is in the adjustment position or not by keeping it collapsed and gently turning it further to the left counting at the same time the half turns until a stop is felt. Stop turning then and do not use force.
Keeping the shock absorber collapsed, make 1 half turn (180 degrees) to the right (clockwise). In case of prior adjustment add the number of half the turns previously found. The total range is about 4-5 half turns, we suggest the MAX crank of 4 (Figure 2).
Pull the shock absorber out vertically without turning for at least 1 cm to disengage the adjusting mechanism. The dust cap or piston rod may now be turned freely (Figure 3).

Rebound Adjustment Knob

KONI sweep window

Figure 1: Window type rebound adjuster- Window is located near the piston rod end mounting attachment. Moving the pin from left to right in upright mounted shocks for rmer, right to left for softer. On inverted mounted shocks, right to left for firmer, left to right for softer.

Rebound Adjustment Procedure

Almost all KONI externally adjustable dampers are quickly and easily adjusted by placing a KONI knob on the adjuster tab that sticks out of the top mounting threading. As shown on the knob, turn counter clockwise for firmer, clockwise for softer.
Some externally adjustable shocks use an adjuster window instead
(Figure 1) of a tab. Insert a pin through the window into a hole,
sweeping from left to right for rmer, right to left for softer

Figure 2: Compression - Insert a screwdriver into the lower adjustment device (Figure 2). Turning the screw driver from left to right (clockwise) will cause the forces to increase. From the minimum or factory positions, there are 12 possible “clicks” of adjustment.

Independent Rebound and Compression Adjustment Procedures

Adjust rebound damping (top when mounted upright) using either the adjuster knob or window type mentioned above.
Adjust compression (bottom when mounted upright) by turning to the right (clockwise) for firmer, to the left (counter clockwise) for softer./li>
