DOES MY BLADE ASSEMBLY NEED REPLACING?
Even the toughest blade assemblies eventually wear out and need replacing. Replacement frequency
is based on use. We recommend that you inspect your blade assembly once a week, following the
instructions below. If the inspection shows you need a replacement blade assembly contact us at www.
internationalwarrantysupport.com.
⊲ If any of the following are present, your assembly needs replacing: nicks, cracks or gouges in the
outer surface.
⊲ Inspect the gears of the blade assembly; the teeth that mesh with the motor unit should be deep and
have continuous edges.
⊲ Inspect the seal, on the bottom of the blade assembly below the gear; if it is missing, lifting or torn,
replace the assembly.
⊲ With the blade assembly in your hand, rotate the blade, checking that it moves smoothly with a
constant and slight resistance.
⊲ Check the blade assembly for vertical movement: holding the assembly in one hand, use the other to
push up and down on the gears. If you feel any vertical movement, it’s time to replace the blade.
As a general rule, the blade assembly should be replaced when:
⊲ The seal is damaged and missing or bearings are visible
⊲ The blades move vertically
⊲ The blades move side-to-side
⊲ There are noises from the blade assembly
⊲ The blade spins without any resistance when testing by hand
⊲ The blade is either difficult to spin or will not spin at all, when testing by hand
CAUSES FOR BLADE ASSEMBLY WEAR
While many factors can cause the blade assembly to wear out, the following are often to blame:
⊲ Washing incorrectly, either in a dishwasher or by using a bleach sanitizer stronger than 100 ppm
⊲ Blending abrasive products (sand, etc.)
⊲ Using parts not approved by Optimum
⊲ Operating the blender with foreign objects in the container
⊲ Incorrect operation of the blender, including: removing or placing the container on the drive socket
while it is spinning, forgoing the use of the centering pad, rocking or tilting the blender while in
operation
⊲ Worn drive sockets can also cause damage to the blade assembly
