4.0 Maintenance
WARNING! Rotating parts and electrical circuits will
be exposed when side covers are removed. Always
turn the machine completely off and disconnect all
power sources when servicing this machine.
Your folder is a precision machine that has been designed to pro-
vide dependable performance over many years. But, like your
automobile, proper maintenance is important for good perfor-
mance. Read this section carefully for helpful hints to keep your
folder operating at peak efficiency.
4.1 Rubber Folding Rollers
The rubber folding rollers on your folder are made of a special-
ly-formulated compound which will provide accurate, reliable
performance over a long period of time PROVIDED THEY
ARE KEPT CLEAN.
During the course of operation, the rollers tend to pick up ink,
lint, talc, powder, and coatings from paper stock. If left to accu-
mulate on the rollers, these substances can cause the rollers to
become slick and hard. HARD, SLICK ROLLERS ARE THE
MAJOR CAUSE OF FEEDING AND FOLDING PROBLEMS.
This causes: inconsistent folding, inconsistent feeding, wrin-
kling the paper, paper coming out of fold table, gaps between the
rollers, and frequent jamming. If your folder shows any of the
above symptoms, the cause is usually DIRTY ROLLERS.
4.1.1 How To Clean Folding Rollers
It is important that you clean your rollers THOROUGHLY. It is
INSUFFICIENT to just clean the surface. You must get the
ground-in foreign matter out of the rollers.
Note : Use Martin Yale Rubber Roller Cleaner and Rejuvenator.
Do not use detergents, blanket wash, or any abrasive cleanser.
Use of any non-recommended cleaning material may deteriorate
the rollers and void your warranty.
Clean the rollers as follows:
1. Disconnect the power supply cord.
2. Remove the feed table and fold tables to gain easy access to
the rollers.
3. Liberally spray
Martin Yale Rubber Roller Cleaner and
Rejuvenator across the rollers.
4. Using a clean cloth or soft nylon brush, press hard, moving
back and forth across each roller. You will see the accumu-
lated ink begin to appear on the cloth or brush. Use the
handwheel to turn the rollers. Continue to apply the roller
cleaner to the entire surface of each roller and clean until no
ink appears on the cloth or brush.
WARNING! Failure to thoroughly and immediately
clean off all residue and cleaning solvents may result
in rollers bonding to each other. This potentially can
lead to damage of the rollers, your machine’s drive
system, and/or the motor.
When your rollers are clean, they should be soft and not hard or
slick to the touch. Regular cleaning will add years of life to your
rollers and will assure you of optimum performance.
4.2 Lubricating Folder
Your folder should be properly cleaned and lubricated EVERY
25 HOURS OF USE to make sure that all moving parts continue
to operate properly.
1. Disconnect the power supply cord.
2. Remove any accumulated lint and paper dust from the ends
of the rollers and bearings with a 1" paint brush.
3. Place one drop of light machine oil in the oilite bearings
located at the ends of the roller shafts.
TAKE CARE NOT TO DROP OIL ON THE RUBBER
ROLLER. Oil can make the roller swell and cause folding prob-
lems. IF ANY OIL DROPS ONTO THE RUBBER ROLLERS,
WIPE IT OFF IMMEDIATELY.
4.3 How To Clean Feed Tire
The feed tire should be cleaned with a damp cloth with soap and
water or a mild detergent. Do not saturate the feed tire with any
liquid. If unable to remove ink from feed tire, a very small
amount of
Martin Yale Rubber Roller Cleaner and Rejuvenator
may be put on a cloth and used to remove the ink. DO NOT
SPRAY OR POUR ANY CLEANER ON THE FEED TIRE.
4.4 Parts and Service
Contact your Martin Yale representative for parts and service.
Include the machine model and serial numbers when ordering.
5.0 Adjustments
Described below are several adjustment which are available to
you on your folder.
5.1 Angular Control Adjustment
This adjustment is factory set and will only be required if the
roller springs are worn, a gap exists between the 1st and 2nd fold
rollers, or you cannot perforate or score parallel to the edge of
your stock. DO NOT MAKE THIS ADJUSTMENT until you
are sure that the paper guides are perpendicular to folding rollers
and that paper is cut square. A crooked fold can be compensated
for by adjusting the paper stops on the fold tables.
Paper pulling to one side after contacting the 1st fold roller can
be corrected by increasing or decreasing the fold roller tension.
Insert the allen wrench provided into the hole in the side cover
near the speed control (Fig. 1). Clockwise rotation of the set
screw inside will result in paper pulling more to the operators'
side (side with handwheel). Counter-clockwise rotation of the set
screw will result in paper pulling more to the side away from the
operator. (Fig. 14). Adjust the screw about 1/8” turn at a time
and test. Do not exceed 1/2” turn in either direction, as it is inef-
