TRIMMER/MOWER™ BEAVER BLADE

Regular maintenance is the way to ensure the best performance and long life of your BEAVER BLADE.
Please refer to this manual for maintenance procedures.
• Use the BEAVER BLADE for cutting wood, brush and small trees ONLY.
• It's a good practice to sharpen the BEAVER BLADE before each use. This allows you to maintain the
proper cutting angle of the teeth before the chain gets too dull. See the following page for
sharpening instructions.
• The BEAVER BLADE does not need to be oiled.
• To avoid premature dulling, keep the blade out of contact with the ground.
• If you are planning to do heavy brush cutting, please consider purchasing the aluminum Mow-Ball™
Support, which better withstands the heat created by the BEAVER BLADE and is more durable under
heavy use.
• If you have any questions, please call us TOLL-FREE 1(800)DR-OWNER(376- 9637). One of our
Customer Service Representatives will be happy to help you.
Sharpening the BEAVER BLADE
Tools Needed:
• 3/16" (4.8mm) round file (never use a rat-tail file) for the 12" chain.
• Flat file
1. Remove the BEAVER BLADE from the cutting (or trimming) head. Leave the chain on the blade.
2. Draw a mark on the chain or BEAVER BLADE where you will begin sharpening.
TIP: Using a vise to hold the Beaver Blade while sharpening will make it easier to make consistent
sharpening strokes.
Note: File the chain with a light pressure into the cutting edge of the tooth. Do not bear down on the file. Give
each tooth the same number of strokes. The teeth are made of a relatively soft metal. It is not necessary to
remove a lot of metal.
ALWAYS DISCONNECT THE SPARK PLUG WIRE(S) BEFORE REMOVING THE BEAVER BLADE AND
WEAR EYE PROTECTION AND GLOVES WHEN SHARPENING YOUR BEAVER BLADE.
YOUR BEAVER BLADE CHAIN IS A SEMI-CHISEL CHAIN WITH A .325" PITCH FOR THE 12" BEAVER
BLADE. SHARPENING YOUR CHAIN THE WRONG WAY COULD SERIOUSLY DAMAGE OR DESTROY
IT. IF YOU’VE NEVER DONE THIS PROCEDURE BEFORE, IT’S GOOD TO PRACTICE ON AN OLD
CHAIN FIRST, OR GET SOME TIPS AND ADVICE FROM AN EXPERIENCED CHAIN SHARPENER.
