COUNTERBALANCE ADJUSTMENT
To adjust the counterbalance, loosen the knob on the weight block and slide the block up or down the arm.
Tighten the knob to set the position of the block. Moving the block towards the motor will decrease the
counterbalance and moving the block away from the motor will increase the counterbalance. See Figure 4.
**When the arm is not in use, slide the weight block towards the rear of the arm to keep the motor in an
upward position. This will extend the life of the cylinder.**
