In some circumstances, it may be necessary to disassemble the press to fit through a small
entryway. If you are having difficulty moving your press through a small door or entryway,
follow these instructions.
Take a wrench and remove the bolt that sits on top
of the cap on the upper carousel wheel
Lift cap off to expose center shaft
Lift the upper turret off of the center shaft and set
aside
Remove the lower turret off the center shaft and
set aside
Mach should now be in 3 smaller pieces allowing it
to fit through a small doorway
Once through the door, put the lower turret and
the upper turret back on the center shaft
Place the cap on top of the upper wheel and secure
the bolt in place with a wrench

ADJUSTING THE OFF CONTACT (F)
Loosen F1, then turn F2 to your desired height.
Refer to p. 21 for additional off contact settings.
USING THE X AND Y MICRO ADJUSTERS (D)
Always loosen the micro lockdown knobs (B)
before adjusting the micros.
To adjust the registration turn the X and Y micro
adjusters (D).
To move the screen left/right or up/down use the
micro adjusters (D).
To move the screen up/down without moving it to
the left/right, turn both micro adjusters (D) at the
same time.
After adjustments are finished tighten the micro
lock down knobs (B), but don’t over tighten.
PRINT HEAD AND MICRO ADJUSTMENTS
ADJUSTING THE SCREEN TILT (E)
Loosen E1, then turn E2 to your desired setting.
USING THE X AXIS MICRO ADJUSTER (A)
Always loosen the micro lock down knobs (B)
before beginning the adjustment.
Turn the side-to-side micro adjuster to move the
screen side to side, to properly set it must be used
in conjunction with the X and Y micro adjusters (D).
To utilize the full range of movement both sets of
adjusters must be used. Always center the micros
either after completing a job or beginning one,
because it will save a lot of movement.
PLACING A SCREEN (C)
To place a screen in the print head, loosen the two
screen lockdown knobs (C) and raise the screen
lockdown clamp bar until the screen can fit in.
Then push the screen all of the way to the back
of the screen clamp. After the screen is properly
placed tighten the two screen lockdown knobs,
but don’t over tighten.
Tip: When using a back clamp printing press always
measure the design height from the back of the screen,
to confirm the design will register even when using
different size screens.

MAINTENANCE
The Mach Series does not require much maintenance, but periodic lubrication and cleaning will ensure
smooth operation and extended life of the components.
Do not let spray adhesive and lint accumulate. Wipe the press daily to remove spray adhesive and lint.
LUBRICATING THE MICROS
To lubricate, use spray lithium grease.
Unscrew the (B) micro lockdown knobs that
attach the micro adjusters to the micro plate.
Raise the head and spray the lithium in between
the top of the head and the internal black
cartridge. While doing so, work the micro
knobs to work the grease and check for smooth
movement of assembly.
To lubricate the micros, back off the adjusters
so most of the thread shows, apply a small dab
of grease and work into the threads. Then screw
down to reveal the other side and then repeat for
the other side.
After all of this, re-center the micros.
CLEANING
To clean the press, avoid using alcohol based
solvents. Oil based paint thinner is better
because it won’t cut and dry out the grease.
TROUBLESHOOTING
If there are issues turning any of the knobs or
micro adjusters, check to see that they are not
gummed up with spray adhesive or ink. If the
carousel becomes stiff or too easy to rotate,
check to see that the top tension nut is not too
tight or loose because it will determine if the
tapered bearings need grease. Take off the jam
nut to reach the resistant nut.

16 3730 E. SOUTHERN AVE., PHOENIX, AZ 85040 | USA
MAINTENANCE
LUBRICATING THE CAROUSEL TAPERED BEARING
It is important to lubricate the top and bottom of the carousel tapered bearing at least twice a year.
Lubrication may also be necessary if the rotation bearing becomes tight or uneven.
Use a wrench to remove the bolt from the Center
Tapered Bearing. Lift the cap off to expose the
center shaft.
Lift the upper turret off of the center shaft.
Take a generous amount of grease and pack it onto
the top and bottom of the center shaft. Remove
the tapered bearing and work the grease onto the
bearing separately. Be careful not to damage the
race on the bearings.
Once complete, return the bearings and the carousel
wheel back into place. Put the cap back and tighten
the bolt with a wrench.
