INSTALLING YOUR DR® TRIMMER/MOWER™ BEAVER BLADE®
This chapter outlines a few simple steps you will need to follow to set up your new DR
TRIMMER/MOWER BEAVER BLADE before you use it. It may be helpful to familiarize yourself with the
parts of your DR TRIMMER/MOWER BEAVER BLADE assembly by reviewing Figure 1 before beginning
the steps outlined in this chapter.

Installation

Note: When using the aluminum Mow-Ball™ Support (recommended), you will NOT need to use the
rectangular washer because one is built in.
Tools Needed:
Long Phillips head screwdriver
Gloves
DR®TRIMMER/MOWER™ Safety & Operating Instructions for reference.
1. Follow the steps in your DR® TRIMMER/MOWER™ Safety & Operating Instructions to remove the
trimmer head assembly from the bearing housing assembly. Remove the flanged bolt or the
standard bolt and rectangular washer insert completely (and store for future use), as they will not be
required when using the aluminum Mow-Ball™ Support.
2. Carefully unpack the BEAVER BLADE. Wear gloves when handling the BEAVER BLADE— the teeth
are very sharp!
