MAINTENANCE

WARNING! To avoid accidents, turn OFF and unplug the tool from the
electrical outlet before cleaning, adjusting, or performing any maintenance
work.
ROUTINE INSPECTION
Before each use, inspect the general condition of the tool. If any of these
following conditions exist, do not use until parts are replaced or the tool is
properly repaired.
Check for:
■ Loose hardware,
■ Misalignment or binding of moving parts,
■ Damaged cord/electrical wiring,
■ Cracked or broken parts,
■ Any other condition that may affect its safe operation.
CLEANING & STORAGE
• Keep the ventilation openings free from dust and debris to prevent the
motor from overheating.
• Use a vacuum or low-pressure compressed air to remove dust and
debris from the tool surfaces, motor housing and work area.
• Wipe the tool surfaces clean with a soft cloth or brush. Make sure water
does not get into the tool.
CAUTION! Most plastics are susceptible to damage from various types of
commercial solvents. Do not use any solvents or cleaning products that
could damage the plastic parts. Some of these include but are not limited
to: gasoline, carbon tetrachloride, chlorinated cleaning solvents, and
household detergents that contain ammonia.
To clean the inside of the unit, turn the hopper locking knob
counterclockwise, and open the hopper. Clean the cutting blades and the
discharge area. Remove wood sticks or objects that may clog the blades.
Check the blades for damage and replace if they show signs of wear.
Replace the hopper and lock the hopper locking knob by turning it
clockwise.
• Store the tool in a clean and dry place away from the reach of children.
• Cover the tool in order to protect it from dust and moisture. It is preferable
to store it in its original packaging with the instruction manual and all
accessories.

Please take this product to your local recycling facility for responsible
disposal and to minimize its environmental impact.
Please recycle the packaging and electronic components where
facilities exist.
REPLACING CUTTING BLADES
The shredder comes with two cutting blades preinstalled that can be
reversed or replaced to keep the cutting edges sharp. The two blades
should always be reversed or replaced as a matched set.
It is recommended to replace/reverse the blades when the wood sticks
cannot be automatically drawn into the shredder after entering the hopper.
One set of sharp edges can cut approximately 400 lbs. of materials,
depending on the hardness and quality of the sticks. When the cutting
capacity is reached, make sure to replace/reverse the shredder blades to
maintain optimal performance.
WARNING! Wear protective gloves to protect your hands. Cutting
blades have sharp edges on both sides and are fragile. Handle the blades
carefully to avoid personal injury or damage to the blades.
• Turn off and unplug the machine. Wait for the blades to come to a
complete stop.
• Fully unscrew the hopper lock knob until it springs out. Open the hopper
to access the cutting head (A).
• Clean out all chips or foreign matter sticking to the cutting head and
blades (B) using a soft brush.
• Rotate the cutting head to the configuration. To prevent the cutting head from rotating
during blade change, insert a screwdriver through the blade guard hole (C) and the
slot in the cutting head.
• Unscrew the two hex bolts (D) on the top blade. Turn the cutting head 180 degrees to
remove the other blade.
• The blades may be reversed when one of the cutting edges becomes dull or chipped.
Reverse the direction of the original blades, or install two new blades. Make sure to
reverse or replace both blades at the same time so they are balanced with one another.
Align the slots on the blade with the grooves on the cutting head.
• Secure each blade with two hex bolts, firmly tighten them with a hex wrench. Close the
hopper and fully tighten the hopper locking knob.

CARBON BRUSH REPLACEMENT
The wear on the carbon brushes depends on how frequently and how heavily the tool is
used. To maintain maximum efficiency of the motor, we recommend inspecting the two
carbon brushes every 60 hours of operation or when the tool stops working.
• Turn off and unplug the machine. Wait for the blades to come to a complete stop.
• The two carbon brushes can be accessed through the front and back carbon brush
cover located on the bottom of the shredder body. Unscrew the Phillips head screw
from the housing and open the carbon brush cover (A).
• Unscrew the two small Phillips screws (B) to remove the carbon brush holder.
Carefully remove the old carbon brushes using pliers.
NOTE: Keep track of which orientation the old carbon brushes were in to prevent
needless wear if they will be reinstalled.
• Measure the length of the brushes. Install the new set of carbon brushes if either
carbon brush length is worn down to 3/16" or less. Reinstall the old carbon brushes
(in their original orientation) if your brushes are not worn down to 3/16" or less.
Both carbon brushes should be replaced at the same time.
• Replace the carbon brush holder and cover. Tighten all screws. Repeat the steps
above to replace the carbon brush located on the other side of the motor.
NOTE: New carbon brushes tend to spark for a few minutes during the first use as
they wear down.
