MOUNTING THE JOYSTICK ADAPTER

70-JS500: Mount joystick adapter bracket 70-JS500 using 1⁄2" hex head bolt 1⁄4" x 20 and 1⁄4" split lock washer provided. Tighten securely. Normally the adapter bracket will be mounted parallel to the fully extended Retract4 arm. However it can be mounted on an offset (right or left) for a particular end user's needs.

70-JS510, 70-JS520, 70-JS530, 70-JS540, 70-JS550, 70-JS570 : Mount joystick adapter by sliding the 1⁄2" hole over the 1⁄2" pivot mount pin D. Securely tighten the 3⁄8" set screw included with the adapter to lock in position.

ASSEMBLY WITH MIDLINE BAR AND TRAY SPACER
The Midline bar extension will mount between the arm and adapter. Pivot pin D on the Retract4 arm will mount to the 1⁄2" hole on the midline bar. The Retract4 adapter will slide over the 1⁄2" pin on the midline adapter mount.
Place Tray Spacer (70-JSML105) between Retract4 arm and Midline Bar to allow joystick controller and Midline Bar to be positioned over tray.

MOUNTING THE RETRACT4 TO THE WHEELCHAIR
Attach the mounting portion (section A) of the Retract4 arm to the receiver bracket on the wheelchair provided by the wheelchair manufacturer. Note that the Retract4 can be mounted for right hand or left hand applications without modifications to the unit.

TENSION CONTROL OF SWIVAL POINTS

(feature available only on Retract4 — Retract4 Lite has a preset swing tension)
Tension of swivel point C can be adjusted using a 3⁄16" x 3" long hex wrench as follows:

a) Insert hex wrench in the end of arm section A
b) Turn internal set screw counter clockwise to lessen tension and create easier movement when folding Retract4
c) Turn internal set screw clockwise to increase tension and create more resistance when folding Retract4
d) Turn internal set screw fully clockwise and tighten to lock Retract4 at this swivel point.

Tension on swivel point D can be adjusted by removing the 3⁄16" set screw completely from the end of arm section B. Slide Section B from the Retract4 assembly. Again, using a 3⁄16" x 3" long hex wrench, tension changes for swivel point D can be made following instructions a thru d above and reassembling the unit.

VERTICAL HEIGHT ADJUSTMENTS OF JOYSTICK CONTROLLER
Vertical height of the joy stick controller on the Retract4 arms 70-JS200 and 70-JS300 can be achieved by loosening the 3⁄8" set screw at the end of section B and sliding the section up or down on pivot pin C. Then retighten set screw when desired height is achieved.

**IMPORTANT**FOR EASIER FOLDING OF THE RETRACT4 FROM AN EXTENDED POSITION
When folding the Retract4 from a fully extended position first rotate controller in at pivot point D one quarter turn, then rotate section B pushing the unit straight back towards the armrest. This will allow the Retract4 to be folded in close to the armrest and out of the way as intended, maintaining the smallest profile.
