LIMITED WARRANTY

Hayter Limited warrants to the original user/purchaser that this unit shall be free from defects in

material and workmanship under normal use and service for a period of one year from the date
of purchase. The manufacturers of the engine furnish their own warranty and services are
provided through their authorised network (Refer to "Engine Warranty Statement"). To qualify
for the full benefit of the warranty, the Warranty Registration Card must be returned to Hayter
Limited within 14 days of purchase. If the selling dealer has not returned the Warranty
Registration Card which is attached to the rear of the Owners Handbook please complete and
return. Subject to the conditions and exclusions noted in this limited warranty, we shall at our
option, repair or replace any warranted part during the applicable period. If you are in doubt or
experience any difficulty, please consult a Hayter Authorised Service Dealer for clarification.

A 90 day warranty period applies to those items which are subject to normal wear and tear e.g.
wheels, cutterbars, cables, grassbags and other consumable wearing parts.

All machines which are fitted with a genuine Hayter Friction Disc or Crankshaft Support
Bearing as original equipment before use, are covered by a Lifetime Warranty against the
engine crankshaft bending. Note: friction washers, Blade Brake Clutch (B.B.C.) units and other
such devices are not applicable. Only machines fitted with a genuine Hayter friction disc or
crankshaft support bearing, which are used in accordance with the recommended operating and
maintenance procedures, are covered.

This warranty does not apply to any unit that has been tampered with, altered, misused, abused or
used for hire, and will become invalid if non genuine Hayter parts are fitted. This warranty does
not cover for minor mechanical adjustments unless they are due to defective material or
workmanship. Consult the Owner's Handbook or a Hayter Authorised Service Dealer for
assistance when making these adjustments.

To make a warranty claim, return the unit to a Hayter Authorised Service Dealer along with proof
of purchase stating the machine serial number and date of purchase. Subject to the conditions and
exclusions in this limited warranty, the authorised dealer will, at our option, repair or replace any
warranted part within the duration of the warranty period.
