Limited Product Warranty
Wood-Mizer LLC (“Warrantor”), an Indiana corporation with its principal place of business at 8180 West Tenth Street, Indianapolis, IN 46214-2400 USA, warrants to the purchaser (“Purchaser”) that
for the time periods specifically stated herein and subject to the terms, conditions and limitations stated herein, the equipment manufactured by the Warrantor will be free from defects in material and
workmanship attributable to Warrantor so long as, during the warranty periods stated herein, the equipment is installed, operated and maintained in accordance with the instructions provided by
Warrantor.
* Warranty on Options will match the warranty on the primary equipment when purchased on same invoice.
Exclusions from 90 Day, Limited One Year and Two Year Warranty
Warrantor shall have no responsibility under this warranty for any wear components, including, but not limited to: belts, blade guides, blades, electric motor brushes, drum switches, filters, fuses,
hoses, bearings (excluding cylindrical drive bearings), bushings, cable carriers, and spark plugs. All wear components are furnished “as is”, without any warranty from Warrantor. This limited
warranty does not cover any defects caused by misuse, negligence, alterations, damage due to overload, abnormal conditions, excessive operation, accident, or lack of performance of normal
maintenance services.
Several components which are used in the manufacture of the equipment but not manufactured by Warrantor such as cant hooks, power plants, laser sights, batteries, tires, and trailer axles have
warranties provided by the original equipment manufacturer (written copies available upon request). Warrantor does not separately warrant such items. Components or equipment manufactured by
third parties are not covered by this warranty. Warrantor, however, will provide reasonable assistance to the Purchaser to make claims against any warranties applicable to such component parts as
provided by such original equipment manufacturers. Components or equipment manufactured by third parties are not covered by this Warranty.
Five Year Limited Chassis Warranty
The limited five year chassis warranty described above, DOES NOT extend to (a) any damage stemming from accident, improper towing, overload, abuse, misuse, abnormal conditions, negligence,
excessive operation, or lack of maintenance, (b) rust caused by exposure to corrosive atmospheric conditions, or (c) the sawmill head, carriage, axle, brakes, or any hydraulic or electrical components
attached to the chassis.
Warrantor’s Obligations as To Defects
In the event that the equipment fails to perform due to defective materials or workmanship attributable to Warrantor under normal use and service within the established warranty period, Purchaser’s
sole and exclusive remedy and Warrantor’s sole liability shall be to replace or repair, in Warrantor’s sole and subjective discretion, any defective part at Warrantor’s principal place of business without
cost to the Purchaser if such defect exists. The determination of whether a product is defective shall be made by Warrantor in Warrantor’s sole and subjective discretion. The Purchaser must notify
Warrantor prior to shipping any defective part. Warrantor, at its sole discretion, may cover expenses incurred in shipping the defective part to Warrantor for evaluation; provided, however, that
Warrantor will not be responsible for labor, travel time, mileage, removal, installation or incidental or consequential damages. However, any part in excess of 140 pounds must be returned by the
Purchaser, to the Warrantor’s nearest authorized facility at the Purchaser’s expense, if return is requested by Warrantor. Warrantor shall have a reasonable time within which to replace or repair the
defective part. If Warrantor determines that the product is not defective under the terms of this warranty in Warrantor’s sole and subjective discretion, then Purchaser shall be responsible for any
expenses incurred by Warrantor in returning the equipment to the Purchaser.
Limitations and Disclaimers of Other Warranties
EXCEPT FOR THE EXPRESS WARRANTY PROVISIONS STATED ABOVE, WARRANTOR DISCLAIMS ALL WARRANTIES, EXPRESS AND/OR IMPLIED, INCLUDING WITHOUT
LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY, AND FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT AND TITLE. No representation or other affirmation
of fact by representatives of Warrantor, whether verbal or in writing, including photographs, brochures, samples, models, or other sales aids, shall constitute a warranty or other basis for any legal
action against Warrantor. There are no other representations, promises, agreements, covenants, warranties, guarantees, stipulations or conditions, express or implied, by Warrantor except as
expressly set forth herein. THE ORIGINAL PURCHASER AND ANY INTENDED USER OR BENEFICIARY OF THIS EQUIPMENT, SHALL NOT BE ENTITLED TO RECOVER ANY INDIRECT,
SPECIAL, PUNITIVE, EXEMPLARY, CONSEQUENTIAL, SPECIAL, OR INCIDENTIAL DAMAGES OR LOSES, INCLUDING BUT NOT LIMITED TO, DAMAGES OF LOST PRODUCTION, LOST
REVENUE, LOST PRODUCT, LOST PROFITS, LOST BUSINESS, LOSS OF USE, LOSS OF GOODWILL, OR BUSINESS INTERRUPTION, FROM WARRANTOR FOR ANY REASON
WHATSOEVER INCLUDING WITHOUT LIMITATION WARRANTY OR DEFECT IN THE PRODUCT REGARDLESS OF THE SOLE, JOINT AND/OR CONCURRENT NEGLIGENCE, BREACH
OF CONTRACT, BREACH OF WARRANTY, STRICT LIABILITY IN TORT OR STATUTORY CLAIMS OR OTHER LEGAL FAULT OR RESPONSIBILITY OF EITHER WARRANTOR OR
PURCHASER OR ITS EMPLOYEES OR AGENTS. Warrantor does not warrant that its equipment meets or complies with the requirements of any particular safety code or governmental
requirements.
Defective items replaced under the terms of this warranty become the property of Warrantor.
Design Changes
Warrantor reserves the right to change the design of its products from time to time without notice and without obligation to make corresponding changes in or to its products previously manufactured.
Rights of Purchasers
The validity and effect of this limited warranty as well as its interpretation, operation and effect, shall be determined exclusively by the principles of law and equity of the State of Indiana, USA. This
limited warranty gives Purchaser specific legal rights. Purchaser may also have other rights, which may vary from state to state. Some states may not allow limitations as to the duration of implied
warranties or to the exclusion or limitation of incidental or consequential damages, so some of the limitations and exclusions detailed set forth above may not apply. In the event that any one or more
of the provisions of this warranty shall be or become invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions of this warranty shall not be
affected thereby.
Interpretations
This Warranty constitutes the entire warranty agreement between Warrantor and Purchaser and supersedes any prior understandings or agreements pertaining to the same subject matter. This
warranty cannot be amended except in writing which refers to this warranty which is signed by both Warrantor and Purchaser.

MD500 Overview:
When using a collection system, keep in mind:
Check your local waste disposal codes before designing your chip collection sys- tem.
Design access to your chip collection bins so that they can be easily emptied.
Short hose runs and smooth-walled hoses reduce suction loss within the system.
Locate the chip collector near the planer moulder.
Collection systems are loud; use ear protection.
If you are operating this machine in a climate-controlled building and blowing the chips outside, the vacuum
created by the chip collector can quickly empty your building of its heated or cooled air.
If blowing the chips to an indoor bin, an air filter will be necessary to prevent wood dust from reducing the air
quality inside of your building.
If selling chips for use with livestock, do not use harsh chemicals for cleaning or lubricating machinery

SECTION 5 OPERATION
5.1 General Use
Always be sure that all safety decals are clean and readable. Replace all damaged safety decals to prevent per-
sonal injury or damage to the equipment. Contact your local distributor, or call your Customer Service Representa-
tive to order more decals.
Always properly dispose of all by-products, including debris as wood shavings and dust, coolant and oil.
The chip extractor should only be used for removing sawdust and chips from the processing of wood.
Check your chip extractor as soon as you receive it. Report any transport damage to the transport company imme-
diately.
Spare parts should be sourced through Wood-Mizer.
All electrical installation, service and/or maintenance should be performed by a qualified electrician.
5.2 Site Preparation
WARNING! Have a qualified electrician install the power to your machine. Failure
to follow this may result in serious injury or death.
CAUTION! Improper voltage will cause damage to the motor and electronic components.
Have a qualified electrician install the power supply to the Chip Extractor.
IMPORTANT! The power supply must meet the motor specifications concerning
wire size, fused disconnect, and voltage, which are provided in the motor’s
faceplate. The electrical installation must also meet local codes.
5.3 Extractor Operation
CAUTION! Do not turn on extractor until the unit has been fully assembled. This includes
inlet hoses or caps, as well as outlet hoses and collection systems. Failure to do so may
result in damage to the machine.
1. Secure one end of flex hose to chip extractor inlets with hose clamps. Unused inlet ports must be blocked off. Fail-
ure to do so may result in machine damage and reduced airflow
2. Secure the other end of the flex hose to the unit producing chips.
3. Secure outlet hose to the outlet port with hose clamps. Outlet hose must go to either a chip collection system, chip
container, or vent directly outside.
4. Start motor by pressing the green start button on the control box.
5. On units with multiple outlet ports, while the extractor is off and disconnected from power supply, adjust the inside
baffle of the (optional bagging system) as needed to divert flow equally between the two outlet ports.
5.4 Collection System Operation
CAUTION! Before operation, ensure both the top filter bags and bottom collection bags
are installed and secure. Replace any damaged filters or collection bags.
NOTE: Use only clean or lightly used filters. Dirty filters must be cleaned routinely for opti-
mal airflow.
