Note: If the brake screws require excessive tightening or frequent adjustment, follow the
steps outlined in the section, Replacing Brake Screws. The frequency of adjustment will
increase as the brake screws wear. While a week may be an appropriate span between
adjustments, a day or less is too frequent.
To Tighten
1. Use a 5mm Allen wrench to tighten both of the brake screws; with your fingertips, turn the wrench
clockwise until you feel the slightest of resistance.
2. Once you feel resistance, turn the brake screw 360° more at the shoulder joint and 270° more at the
elbow joint.
3. After tightening both brake screws, check for drifting by moving the arm and letting go. The arm should
stop when you stop moving it. If it continues to drift, tighten it in 90° adjustments and check again for
drifting.
4. Finally, tighten the brake screw at the shoulder joint an additional 360° and the brake screw at the
elbow joint an additional 90° to allow for brake wear.
Note: If you have a torque wrench, the recommended brake screw adjustment for the
Extension Arm is 97.4 lb-in (
1100 Ncm) at the shoulder joint and 53 lb-in (600 Ncm) at the
Elbow joint.
To Loosen
1. Use a 5mm Allen wrench to loosen the brake screws, turning counterclockwise 90°.
2. Check for ease of movement. If it is still too difficult, loosen it 90° more and check again for ease of
movement.
7.3.2 Adjusting Spring Arm Tension
The Spring Arm tension controls the vertical (up and down) movement of the Spring Arm. It is located at the
elbow joint of the Spring Arm. To test the tension of the Spring Arm, push the light head toward the ceiling.
If it drifts down, increase the tension. Pull the light head toward the floor. If it rises, decrease the tension.
Note: The Spring Arm should always be parallel to the floor while adjusting the tension.
