option, the replacement or refund of the purchase price, of any products or parts or
components thereof which are returned to seller freight prepaid and which are defective in

Commission Improvement Act, 15 U. S. C. Sections 2301-12, which are purchased by
buyer for purposes other than resale. If buyer is not intending to resell the products, and if
the products are consumer products as defined in the Magnuson-Moss Act, the foregoing
warranty, but not the limitation of seller's liability, shall be null and void. EXCEPT AS
EXPRESSLY STATED ABOVE, SELLER MAKES NO WARRANTY, EXPRESS OR

PURPOSE OR USE OR OTHERWISE, ON THE PRODUCTS, OR ON ANY PARTS OR
LABOR FURNISHED DURING THE SALE, DELIVERY OR SERVICING OF THE
PRODUCTS.
1-5 Precautions of Use and Installation
1. Side loading of the lifting screw is not permitted in the dynamic operation of the jack.
A limited side load is allowable in the static condition. Contact Joyce/Dayton for the
allowable side load for a specific application.
2. Extending mechanical stops are provided on the actuator lifting screw. It is the
customer’s responsibility to provide travel limit devices on all ball screw
ComDRIVEs®. The mechanical stop is only an auxiliary device to limit the travel of the
lifting screw. Engaging a mechanical stop during operation can cause damage to the
internal jack mechanism.
3. In most applications, factory or manufacturer-assisted installation is not required.
However, it is necessary that appropriate, qualified personnel perform the installation
of Joyce/Dayton products.
4. Joyce/Dayton ball screw ComDRIVE® actuators are not rated for shock-loading,
extreme vibration or critical speed conditions (high speed or long-length screw.) It is
the responsibility of the user to ensure these conditions are not imposed on the
actuator or the power transmission equipment. Contact Joyce/Dayton for technical
assistance.
5. In the event that service or maintenance is required, the load must be secured or
removed before any work can begin.
6. Ball screw ComDRIVE® actuators can be mounted and operated in any orientation.
When used with the lifting screw in a horizontal position, the worm should be mounted
parallel with the horizon and below the gear to ensure proper lubrication. Standard ball
screw ComDRIVE® actuators are shipped with all holes plugged. The user must insert
the vent in the highest location at final installation.
7. Never allow the actuator to retract beyond the minimum closed position, as damage to
the jack can occur.
8. Boots or protective bellows covers should be used to protect and keep the lifting
screw clean in dusty or abrasive environments.
9. For continuous or high-duty cycles inquire with your local sales representative or
consult Joyce/Dayton Corp. regarding Bevel Ball actuators.
1-6 General Installation instructions
1. Ensure that all personnel who will service or operate equipment are familiar with its
use and limitations.
2. Secure or remove the load before any installation procedures begin.
3. Be certain the rating of the ball screw ComDRIVE® meets or exceeds the load.
4. Ball screw ComDRIVEs® must be mounted on a structure sufficient to support the
maximum possible load. The structure must be rigid. An under-designed structure
could lead to bending of the lifting screw causing premature wear or failure.
5. In a system with shafts, miter boxes, etc., confirm that the shafts and actuators
operate without binding or excessive force before powered drive devices are engaged.
