4.3.3 Cord Control - When using a hoist with cord control, pull down on the appropriate colored cord to raise
or lower the hoist. White indicates the raise control and red indicates lowering control. Release the
cords to stop the hoist. Refer to Figure 4-2 below.

Make sure the motor completely stops before reversing direction.
4.4 Adjusting the Controls
4.4.1 For pendant control, the speed can be adjusted by the amount the lever is depressed. As shown below
in Figure 4-3, by depressing the lever slightly, you will be able control the hoist’s motions slowly and
with more precision. By depressing the lever further, the speed of the hoist will be increased until the
lever is fully depressed.
4.4.2 By adjusting the set screw in the pendant, the control can be adjusted to suit the user’s needs.
Adjusting the screw does not affect the speed of the hoist; it simply changes the feel or stiffness of the
lever control. Adjusting the screw sets the position of a small spring plunger and this affects how the
plunger interacts with the lever.
 Turning the screw in causes the spring plunger to be in contact with the lever for more of the lever’s
travel, resulting in more stiffness and better feel for finer control of hoist motions.
 Turning the screw out reduces the effect that the spring plunger has on the lever control. This
makes it easier to depress the lever, which is usually preferred for coarse control (more on/off than
variable) of hoist motions.

4.4.3 For the cord type control, adjust the speed by varying the amount of pull on the cord. Refer to Figure
4-4.
