Allen Engineering Corporation (“Allen”) warrants its products to be free of defects in material or workmanship
for:
TWO YEARS FROM END USER’S DATE OF PURCHASE
Warranty period begins on the date of purchase by the End User of the product. 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 or batteries. Engine warranty claims should be made directly to an authorized factory service center
for the particular engine manufacturer. Batteries are not warranted due to unknown treatment during transport, etc, and any battery
claims should be directed to the battery manufacturer.
5. Allen’s warranty does not cover the normal maintenance of products or its components (such as engine tuneups and oil & lter chang-
es). 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, modication to product, alterations or repairs made to the product without the written approval of Allen. Allen specically
excludes from warranty any damage to any trowels resulting from an impact to the rotors.
7. Impact damage to gear boxes is not covered under the Allen warranty and is deemed customer abuse.
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 determines 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; ENVIRON-
MENTAL 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.

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 ofcer of Allen Engineering Corporation.

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 ” circumstances. 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.
