Sherline 4400 Lathes - Assembly and Instruction Guide

Sherline Service Policy
Sherline’s policy regarding customer service is simple: CUSTOMER SATISFACTION!
Because products manufactured by Sherline are produced and assembled in our Vista, California plant, we oer fast
and reasonably priced service. All we ask when you pack the items for shipping is to use common sense, individually
protecting items from one another during shipping. Ship by UPS or FedEx ground whenever possible. If you have
attempted a repair and then decide to return the item it is not necessary to reassemble the machine. If you have lost a
part, don’t worry, we’ll still get it looking great for you and return it via UPS or FedEx*. Work and parts not covered
under warranty can be charged to your credit card for your convenience or we can call with an estimate at your request
before performing any work. Again, please email or call Sherline to obtain an RMA number before returning anything
for service. Cleaning the returned items thoroughly before you ship them will save time and money.
*If merchandise is received damaged by the shipper, keep the original shipping carton and contact us to let us know that your package was damaged.
How to Order Replacement Parts
The model number of your machine will be found on the chrome nameplate attached to the top or side of the headstock.
The serial number is laser engraved into the back of the headstock. Always mention the model number when requesting
service or repair parts for your machine or accessories.
Replacement parts may be ordered from the factory or from any Sherline dealer. The most expeditious way to order
parts is directly from the factory by phone, fax or our website at www.sherline.com. Oce hours are 8 AM to 4 PM
(PST or PDT) Monday through Friday. We do our best to see that orders received before 12 noon (Pacic Standard or
Daylight Time) will be shipped the same day. We accept payment by Visa, MasterCard, Discover or American Express.

Full One-Year Warranty on Sherline’s 3.5" Metal Lathe, Vertical Milling Machine, and Accessories
If within one year from the date of purchase a new* Sherline power tool fails due to a defect in material or workmanship,
Sherline will repair it free of charge. In addition, it has always been our policy to replace all parts at no cost, regardless
of age, which are determined to have been incorrectly manufactured or assembled and have failed due to this cause
rather than because of improper use or excessive wear caused by continuous use in a production environment.
90-Day Warranty on CNC and Computer-Related Components
If a new* CNC or computer-related component sold by Sherline fails within 90 days of purchase Sherline will repair
it free of charge. These components include, but are not limited to, controllers, driver boxes, stepper motor cables,
computers, and other computer-related components.
Right of Inspection
Sherline will inspect the machine or part and will be the sole judge of the merit of the claim. Freight charges for returning
a machine are not covered. Merchandise which has been abused or misused is not subject to warranty protection.
Disassembly of a machine or accessory beyond normal maintenance procedures described in this manual may void the
warranty. Before attempting major repairs, call the factory for advice and instructions.
Warranty service is available by simply returning the machine, defective assembly, or part to:
Sherline Products, Inc., 3235 Executive Ridge, Vista, CA 92081-8527
Please write, fax, call, or email to let us know that you are retuning a part and to receive a return authorization
number. This will speed up the warranty process (Email is [e-mail])
This warranty gives you specic legal rights, and you may also have other rights which vary from state to state.
*NOTE: Only new machines purchased directly from Sherline or from an authorized Sherline dealer are covered by this warranty. This includes machines
purchased via on-line auctions when oered by Sherline or its authorized dealers. Machines purchased second-hand or from a non-authorized dealer are
considered “used” and are not subject to warranty even if they appear to be new in the box. If you are in doubt about the status of a dealer or are suspicious
about an oer that doesn’t seem quite right, you can always conrm a dealer’s status by checking our DEALERS page (sherline.com/authorized-sherline-
dealers/) for a listing or by calling [phone] to conrm a dealer’s authority to represent Sherline.
The line lter cuts electronic
emissions to meet CE standards.
Electronic Line Filter makes Sherline Tools CE Compliant
As countries around the world have tightened up their import regulations, Sherline has taken
the extra step to make available an in-line electronic lter between the DC motor speed
control and the incoming AC current in order to meet CE standards. Users outside the USA
will only need to supply a wall plug adapter to go from the American style 3-prong plug to
the type of plug used in your country. An extra charge applies for machines ordered with this
lter installed, but the shipping box will state that the machine complies with CE standards.
We highly recommend that customers in countries requiring CE certication order this part
in order to avoid possible problems with customs.
CE Filter added to any machine: Part number plus letters -CE, Retrofit filter/cord only: P/N 45500
