Disassembly

· Ensure the weight of the chair assembly is supported. When the actuator is removed the chair

will fall forward.

· Remove wire protecting sleeve and disconnect actuator.

· Remove screws (2) using 4mm hex wrench.

· Gently tap out the bearings (3) ensuring the spacers are gathered (4). The actuator (1) may

need tapping lightly to remove.

13.3

· To reassemble the actuator reverse steps 1-3.

· The assembly/disassembly process is the same for the manual seat angle adjustment

assembly.

NOTE:

The screws should not be tightened excessively – the spring washers will ensure the screws do

not work loose. Excessive tightening could result in a) the hex screw becoming rounded, or b)

the sheet metal tightening applying excessive load on the actuator (friction).

If using the manual seat tilt angle adjustment assembly, ensure the collar and hand wheel

assembly (5) is sufficiently lubricated to ensure ease of angle adjustment.

13.4

Requirements:

· Multimeter

· Check the electrical resistance of the actuator. If it is close to infinite, then the motor is likely to

be burnt out. If it is less than 1Ω, then the motor has a short circuit. In either case, the motor

needs to be replaced.
