OPERATING:

Two or three feet from the corner, make a starter cut
three to four inches long, leaving excess carpet running
up the wall.

Place the trimmer into the
cut. Keep the bottom of
the trimm er flat against
the carpet, and the bot­tom edge of the wall run­ner at the junction of the
floor and the wall. (See
fig. 12.)

Push the tr immer along
the wall with your outside
hand. Using your inside,
or wall-side hand, pull the
ca rp e t be ing trim me d .
(See fig. 13.) The pull­ing tension on the cut-off
pi ece make s tri m mi n g
easier.

For a clean, smooth, fin­ished edge, the excess is
tucked into the gully be­tween the wall and tack­less with a stair tool.

ADJUSTING THE TRIMMER:

BLADE SELECTION:

Top loading blade holders allows fast blade change.

Simple shim adjustment for height of cut. Shims need
not 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 toe­spaces.

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. (See figure 1.) It is important to keep the beveled edge
of the trimmer blade up. This causes the nap of the carpet
being cut to be deflected up and away from the trimmer.

With the beveled edge of the blade down, the cut nap will be
pushed down, underneath the wall runner. This causes the
trimmer to rise and gives you a longer cut than desired.

USE ONLY TRIMMER BLADES!

ONLY ONE BEVELED EDGE

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 deter­mined by BOTH the blade height AND the throat opening.

The THROAT OPENING holds carpet in proper position.
(See figure 8.)

The BLADE HEIGHT determines where the blade will cut.
(See figure 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 figures 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 hold 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.

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 figure 7.) The four lines inscribed on the
top of the wall runner also provide a visual reference. The
line which is selected should be made parallel to the shim
deck for proper operation. Adjust the throat for specific
thickness of carpet to be trimmed.
