Limited Warranty
LIMITED WARRANTY and LIMITATION OF LIABILITY
Allen Engineering Corporation (“Allen”) warrants its products to be free of defects in material or workmanship for the following
periods:
A. New Machines and Parts .......................... One Year
B. New Gear Boxes ........................................ Two Years
The above listed warranty periods are effective for Allen Machines with a first day of use by End User on April 1, 2007 or later.
Warranty period begins on first day of use by End User. This first day of use is established by the date of a completed Allen
Warranty Card or a Bill of Sale to the End User. All warranty is based on the following limited warranty terms and conditions,
including the disclaimer of implied warranties and consequential damages.
1. Allen’s obligation and liability under this warranty is limited to repairing or replacing parts if, after Allen’s inspection,
there is determined to be a defect in material or workmanship. Allen reserves the choice to repair or replace.
2. If Allen chooses to replace the part, it will be at no cost to the customer and will be made available to the Allen Distributor,
Dealer, or Rental Center from whom the End User purchased the product.
3. Replacement or repair parts, installed in the product, are warranted only for the remainder of warranty period of the
product as though they were the original parts.
4. Allen does not warranty engines. Engine warranty claims should be made directly to an authorized factory service center
for the particular engine manufacturer.
5. Allen’s warranty does not cover the normal maintenance of products or its components (such as engine tune-ups and oil &
filter changes). The warranty also does not cover normal wear and tear items (such as belts and consumables).
6. Allen’s warranty will be void if it is determined that the defect resulted from operator abuse, failure to perform normal
maintenance on the product, modification to product, alterations or repairs made to the product without the written approval
of Allen. Allen specifically excludes from warranty any damage to any trowels resulting from an impact to the rotors.
7. Impact damage is not covered under the Allen Gear Box warranty.
8. Allen will pay shop labor on warranty items at the Allen Shop Labor Rate in existence on the date of the warranty claim. An
Allen Labor Chart will determine the time allowed to complete a repair and will govern the shop labor hours that will be
allowed.
9. Allen will pay freight on warranty replacement parts at worldwide standard ground rates. No warranty replacement parts
will be shipped air freight at the expense of Allen. Allen only pays outbound freight charges when sending warranty
replacement parts to the customer via ground service. Allen does not pay any inbound freight. However, if Allen deter-
mines
this to be a warranted item, only then will Allen reimburse the customer for inbound freight at standard ground rates.
10. ALLEN ENGINEERING CORPORATION’S WARRANTY POLICY WILL NOT COVER THE FOLLOWING: TAXES; SHOP
SUPPLIES; ENVIRONMENTAL SURCHARGES; AIR FREIGHT; TRAVEL TIME; LOSS OF TIME; INCONVENIENCE;
LOSS OF RENTAL REVENUE; RENTAL COSTS OF EQUIPMENT USED TO REPLACE THE PRODUCT BEING
REPAIRED; LOSS OF USE OF THE PRODUCT; COMMERCIAL LOSS; OR ANY OTHER CHARGES WHATSOEVER OR
ANY LIABILITIES FOR DIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGE OR DELAY.
11. ALLEN ENGINEERING CORPORATION MAKES NO OTHER WARRANTY, EXPRESSED OR IMPLIED. THIS LIMITED
WARRANTY IS IN LIEU OF THE WARRANTY OF MERCHANTABILITY AND FITNESS. THERE ARE NO OTHER
WARRANTIES THAT EXTEND BEYOND THE DESCRIPTION ON THIS DOCUMENT.
12. No Allen employee or representative is authorized to change this warranty in any way or grant any other warranty unless
such change is made in writing and signed by an officer of Allen Engineering Corporation.

Sound And Vibration Data
Sound Pressure Level Information:
Sound pressure is “A” weighted . Measured at the operators ear position while the ride-on trowel
is operating at full throttle on concrete in a manner most often experienced in “normal ” circum-
stances. Sound pressure may vary depending upon the condition of the concrete. Hearing
protection is always recommended.
Vibration Level Information:
The vibration level indicated is the maximum RMS (Root Mean Square) velocity value obtained
at the handle grip while operating the ride-on trowel on curing concrete in a manner most often
experienced in “normal ” circumstances. Values were obtained from all three axes of motion. The
values shown represent the maximum RMS value from these measurements.

SAFETY
Federal Regulations
SILICOSIS WARNING
Grinding/cutting/drilling of masonry, concrete, metal and other
materials with silica in their composition may give off dust or
mists containing crystalline silica. Silica is a basic component
of sand, quartz, brick clay, granite and numerous other min-
erals and rocks. Repeated and/or substantial inhalation of air-
borne crystalline silica can cause serious or fatal respiratory
diseases, including silicosis. In addition, California and some
other authorities have listed respirable crystalline silica as a
substance known to cause cancer. When cutting such mate-
rials, always follow the respiratory precautions mentioned
above.
RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete, metal and other
materials can generate dust, mists and fumes containing
chemicals known to cause serious or fatal injury or illness,
such as respiratory disease, cancer, birth defects or other
reproductive harm. If you are unfamiliar with the risks associ-
ated with the particular process and/or material being cut or
the composition of the tool being used, review the material
safety data sheet and/or consult your employer, the mate-
rial manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources on hazardous materi-
als. California and some other authorities, for instance, have
published lists of substances known to cause cancer, repro-
ductive toxicity, or other harmful effects.
Control dust, mist and fumes at the source where possible.
In this regard use good work practices and follow the recom-
mendations of the manufacturers or suppliers, OSHA/NIOSH,
and occupational and trade associations. Water should be
used for dust suppression when wet cutting is feasible. When
the hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for the
materials being used.
