ABOUT YOUR WARRANTY
We welcome warranty repair and apologise to you for being inconvenienced. Any Authorised Service Dealer may perform warranty
repairs. Most warranty repairs are handled routinely, but sometimes requests for warranty service may not be appropriate. For example,
warranty service would not apply if equipment damage occurred because of misuse, lack of routine maintenance, shipping, handling,
warehousing or improper installation. Similarly, the warranty is void if the manufacturing date or the serial number on the backpack
sprayer or engine has been removed or the equipment has been altered or modified. During the warranty period, the Authorized
Service Dealer, at its option, will repair or replace any part that, upon examination, is found to be defective under normal use and
service. This warranty will not cover the following repairs and equipment:
• Normal Wear: Outdoor Power Equipment, like all mechanical devices, needs periodic parts and service to perform well.
This warranty does not cover repair when normal use has exhausted the life of a part or the equipment. Maintenance and wear
items such as filters, seals, spark plugs, gaskets, clutch pads, are not covered by warranty due to wear characteristics alone,
unless the cause is due to defects in material or workmanship.
• Installation and Maintenance: This warranty does not apply to equipment or parts that have been subjected to improper
or unauthorised installation or alteration and modification, misuse, negligence, accident, overloading, overspeeding,
improper maintenance, repair or storage so as, in our judgment, to adversely affect its performance and reliability. This
warranty also does not cover normal maintenance such as air filters, adjustments, fuel system cleaning and obstruction
(due to chemical, lime, dirt, and so forth).
• Stale Fuel: In order to function correctly, this product requires fresh fuel that conforms to the criteria specified in the Operator's
Manual. Damage caused by stale fuel (carburettor leaks, clogged fuel tubes, sticking valves etc) is not covered by warranty.
• Other Exclusions: This warranty excludes wear items such as quick couplers, seals, o-rings, pumps that have been
run without water supplied or damage or malfunctions resulting from accidents, abuse, modifications, alterations, or
improper servicing or freezing or chemical deterioration. Accessory parts, such as guns, hoses, nozzle extensions
(wands), and nozzles, are excluded from the product warranty. This warranty excludes used, reconditioned, and
demonstration equipment and failures due to acts of God and other force majeure events beyond the manufacturers
control.

Spray pressure setting tips
The spray pressure setting method can be done in two ways.
1. Pressure setting via the pressure regulation dial.
- Turn in clockwise direction to increase the pressure, or;
- Turn in anticlockwise direction to decrease the pressure.
2. Pressure setting via the throttle control lever adjustment .
This will maximise the performance and fuel efficiency:
- Lower engine speed for lower spray pressure, or;
- Maximum engine speed for maximum spray pressure.
NOTE: Limiting the pressure using the pressure regulator
dial will provide better protection of inadvertent error when
the operator increases the pressure via the throttle control
lever. Setting a lower pressure for longer periods of time,
using both the pressure regulator and a lower RPM together is
recommended to reduce wear on components.
