installing Type 'Y'. Original grease may be similar in color but not

compatible with 'Y'. Clean gear assemblies with a clean, dry cloth.

It is important to note that there are two

different Fixtec Nut designs that can be

used on the 2785-20 M18 FUEL Grinder.

Each Fixtec Nut utilizes a spanner wrench

that is unique to the nut.
Fixtec Nut 05-59-0015 (1) must be used

with Spanner Wrench 49-96-0002 (33).

Fixtec Nut 05-59-0016 (34) must be used

with Spanner Wrench 49-96-0004 (35).
Use this diagram to determine the nut and

wrench design and order service parts

accordingly.
