1.2 Installation
Notes on Installation
Avoid use or storage of the cutter in places subject to direct sunlight or the direct draft
from air-conditioning systems.
Avoid locations that are extremely dusty or humid.
Prior to cutting, ensure that no obstacles are placed in the vicinity of the carriage or
material. Impeded movement of the carriage or material may prevent accurate cutting.
To prevent malfunctions of the cutter’s sensors, position the cutter at least one meter
away from electric lights, and any other sources of indoor illumination.
ØØCaution
Lubrication of the mechanisms is not required and will result in cutter malfunctions.
To avoid scratching the cutting pad, ensure that the Blade is properly extended.
While the cutter is operating, do not touch the moving parts.
When manually moving the carriage to load material, be sure to do so slowly.
1.3 Maintenance
Daily Maintenance
During the course of daily cutter operation, be sure to observe the following precautions
Never lubricate the mechanisms of the cutter.
If the cutter’s casing becomes dirty, wipe the soiled areas using a dry cloth or a cloth that
has been moistened in a neutral detergent diluted with water.
Never use thinner, benzine, alcohol, or similar solvents; they can damage the finish.
If the cutter becomes dirty, wipe soiled areas using a dry cloth or use a cloth that has
been moistened in alcohol or in a neutral detergent diluted with water.
Never use benzine, thinner, or similar solvents to clean the sensors.

STAND ASSEMBLY for the Model 515/525 Pro-Series Stand
The Pro-Series Stand consists of two (2) Legs, a Front Panel, and two (2) Rollers to hold material rolls. Assembly is a
simple matter of joining the two legs by putting screws (¼-20 x 1½” Truss Head Machine Screws) through pre-drilled
holes in each leg and through matching holes in the front panel, then securing each screw with a lockwasher and a hex
nut. One Roller is provided without a Brake System (no spring), this roller installs into pre-drilled holes in the rear
“wings” which protrude from the rear of each leg. (See Diagram). The rear-most roller is provided with a Brake
System (Tension Spring on one side) which can be engaged or dis-engaged by simply locating the spring on the left or
right of the cart, (flipping the roller over and dropping it into the provided slot).
1. Select one of the legs and note the marking on the upper mounting plate (either LEFT or RIGHT). The marking
indicates on which side of the stand to put the leg, (either Left Side or Right Side as you face the short bottom arm of
the leg). NOTE: The “Wing” which protrudes toward the rear of each leg is always mounted on the “Outside” of the
leg, (i.e. the left leg has the wing on the left side).
2. From the package of fasteners, select one of the ¼-20 x 1½” machine screws and insert it through one hole in the
side of the leg and through the matching hole (top or bottom) in the front panel. The front panel mounts between the
two legs and is attached by four long screws running through pre-drilled holes in the legs. (See Layout) The label on
the inside of the panel faces the rear of the stand and is not visible from the front side of the cart after assembly.
Flanges on the front panel face to the rear. Insert each of the four (4) long screws and install a lockwasher and hex nut
on each (inside the front panel) DO NOT TIGHTEN THE SCREWS AT THIS TIME! It is necessary for the leg-to-
panel joints to be loose so that you can insert the Front Roller through the pre-drilled holes in the wings, which protrude
from the rear of each leg.
3. The Front Roller does not have a Tension Spring and is provided with a threaded shaft protruding from each end.
(See Diagram). Each end of the Front Roller is inserted through one of the holes in the leg wings, one on each side,
then the roller is secured by threading a “Cap Nut” (see parts diagram) onto each threaded shaft and snugging it against
the side of the leg wing. Once the Front Roller is installed through the leg wings, you may place the legs in an upright
position on a flat surface (either floor or table) and tighten the four (4) long screws which secure the front panel to the
legs.
4. Check that the casters are snuggly threaded into the legs, note that the front casters have brakes to secure the stand in
place. Install the Rear Roller (remaining roller with a spring) into the slots on the rear of each wing , simply lower the
roller into the slots with the Spring located on the Right Side to engage the brake or the Spring located on the Left Side
to release the break.
5. The Brake should be Engaged if you Suspend a material roll from the single rear roller, this will prevent the free
unrolling of material due to the natural tendency of a roll of material to “unwind”. BREN Stencil Material is commonly
suspended from a single roll to prevent having to bend the material backward to achieve a “feed loop”.
6. When running most thin Vinyl and Masking Materials, it is usually not necessary to suspend the rolls but rather to
“Cradle” the rolls by placing them on top of the two rollers so that the roll is supported or cradled by both rollers. When
material is cradled you will usually not require the Brake and will simply flip the rear roller over so that the Spring is
located on the Left side of the stand. (Left side as you face the front of the Stand)
7. Mount the cutter on the stand by locating the cutter on the mounting plates so that the slotted holes in the mounting
plates align with threaded holes in the bottom of the cutter. Using the four 6mm x 12mm pan head screws, attach the
cutter to the plates by running a screw up through the slot in the plate and into a threaded hole in the cutter. Use all four
screws as this will ensure that the cutter is properly aligned with the rollers and is secure to the stand.
8. USE CAUTION WHEN ROLLING THE STAND TO PREVENT IT FROM TIPPING OVER.
9. Load material rolls so that the material feeds from the top of the roll and directly into the back of the cutter, (see
diagram). Material rolls can be loaded to ride on both rollers in a cradle or can be suspended from the single rear roller
by inserting the rear roller through the core of the roll and allowing the material to hang on and be suspended by the
single rear roller. The rear roller is designed to easily lift up and drop into the two slots located on the rear of the wings.
This allows for easy removal and replacement of the rear roller.
