Limited Warranty
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 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 main-
tenance 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; 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 LIABILI-
TIES 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 WARRAN-
TIES 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.

SECTION 1
SAFETY
General Safety
For the vehicle to work properly it must be set up perfectly (installation and use) and the oil level of the
various mechanisms must be veried. An inaccurate inspection or incorrect installation or improper use
can impair the vehicle efciency and compromise operator safety.
All the information and diagrams in this manual refer to the model in production at the time of publica-
tion.
For more information contact an Authorized Service Center.
Allen Engineering Corporation reserves the right to make changes without prior notication.
Everything in this manual belongs to the AEC, therefore no part or diagram can be used for any other
use without authorization.
Caution is the principal factor in preventing accidents and injuries.
Before starting up the vehicle, carefully read all the instructions in this booklet. Should doubt or uncer-
tainties arise, contact the manufacturing company.
• Before starting the engine, make sure that there are no people near the vehicle, especially children.
• It is strictly forbidden to transport or lift people.
• Do not use the vehicle unless you are physically t.
• Do not drink alcoholic beverages while at work.
• This vehicle is not approved for road circulation.
• Do not use the vehicle on steep slopes but only on ground with a gradient that is less than the limits
indicated further stated in this manual.
• It is strictly forbidden to abandon the vehicle while the engine is running or with the ignition key insert-
ed. The engine must always be stopped.
• It is strictly forbidden for minors to use the vehicle.
• Do not use the vehicle in closed or poorly ventilated areas: exhaust fumes are toxic and could be
seriously harmful to the body and may even be fatal.
The vehicle must be refuelled with the engine switched off. Always keep away from ames and do not
smoke.
