ADJUSTMENT
OPERATING:
1. Two or three feet from the corner, make a starter cut
three to four inches long, leaving excess carpet running
up the wall.
2. Place the trimmer into
the cut. Keep the bot-
tom of the trimmer at
against the carpet, and
the bottom edge of the
wall runner at the junc-
tion of the oor and the
wall. (See g. 12.)
3. Push the trimmer along
the wall with your out-
side hand. Using your
inside, or wall-side hand,
pull the carpet being
trimmed. (See g. 13.)
The pulling tension on
the cut-off piece makes
trimming easier.
4. For a clean, smooth, n-
ished edge, the excess
carpet is tucked into the
gully between the wall
and tack strip with a stair
tool. FIG. 13

ADJUSTING THE TRIMMER:
BLADE SELECTION:
Top loading blade holders allows fast blade change.
Simple shim adjustment for height of cut. Shims do not
need to be removed to adjust cutting height. Built-in
lifter points on the wall runner make it easy to separate
the shims and re-insert the blade holder.
Four position adjustable throat to accommodate varying
pile height and density.
Ratchet handle folds down for trimming under toe-space
areas.
Trims in both directions.
Stainless steel base plate and wall runner with plastic
protective coating are both non-marking and will not rust.
FEATURES:
FIG. 1
BEVELED EDGE
•
•
•
•

•
Unlike utility blades, trimmer blades are beveled on one side
only, the top side. (See gure 1.) It is important always to
install blades with the beveled edge of the trimmer blade
facing up.
If blades are installed with the beveled edge down, this
produces a wedging action that will cause the trimmer to
rise, and produces a longer cut than desired.
USE ONLY TRIMMER BLADES!

The best multi-purpose setting for trimming most of today’s
carpets is:
THROAT OPENING: AT #2 HOLE
BLADE HEIGHT: 4 SPACERS
OPTIMIZING BLADE HEIGHT AND THROAT ADJUSTMENT:
The amount of carpet remaining after trimming is deter-
mined by BOTH the blade height AND the throat opening.
The THROAT OPENING holds carpet in proper position.
(See gure 8.)
The BLADE HEIGHT determines where the blade will cut.
(See gure 9.)
For example: A wide opening (throat position at #4 hole)
used on a thin carpet will give you a shorter cut, because
the carpet is not held upright, but allowed to lay at an angle.
(See gures 8 and 9.)
#1 IS NARROWEST THROAT
#4 IS WIDEST THROAT
INSERTING THE NEW BLADE:
Place a new blade bevel side up in the blade pocket, and
push it forward as far as possible until it contacts the inner
edge of the wall runner. After pressing the blade forward,
a rectangular hole in the blade pocket becomes visible.
Place the blade clamp back in the blade pocket with the
indent in the back edge of the blade clamp seated in the
rectangular hole.
Throat adjustment adjusts the throat of the trimmer for
specic thickness of carpet to be trimmed. As you are
re-inserting the wall runner, you can seat it into one of the
four sockets which are visible from the top of the shim deck.
(See gure 7.) The four "throat adjustment lines" inscribed
on the top of the wall runner provide a visual reference.
Make sure that the throat adjustment line which is selected
is set parallel to the front edge of the shim deck for proper
operation.

Insert the lifter point of the wall runner into a lifter socket in
the shim deck that provides the desired height of cut. (See
