for elebtric current to reduce the risk of electric shock. This machine is equipped v/ith a Ground Shield surrounding the
TerminalPins;this Ground Shield isdesigrredto beusedwith aMaimin Grounded Connector,partnumber4584'or458B.
See wiring instructions supplied with the C.onnector. v
DAN GER-t-oroper connection of the Maimin C-onnector can result in a risk of electric shock. Check with a

I. DESCRIPTION
1.1 GENERAL
Your new Maimin Sabre straight knife machine is delivered
ready for operation. It is merely necessary to connect it to an
electrical outlet of the correct voltage, oil it, and then begin
cutting. The straight knife machine can be used for cutting
various types of materials from a few ply to the full capacity
of the machine. However. for best results. it is recommended
thatthe minimum height of the laybe no lowerthan the bottom
ofthe cutting blade at its highest position. The Presserfoot Leg
(KeyNo. ,4'403) acts as aprotective guardforthe operatorsothat
it should be down at all times. The Presserfoot should lie lightly
on top of the lay w[en cutting in order to prevent the material
from vibrating.
1 .2 FLEXIBANDS AVAILABLE
Three different grits of "FlexiBands" are available for sharp-
ening the blade:
Coarse - For hard or coarse materials
(Part 1450 - Box of 100)
(Part 1457 -Box of 500)
Medium - For.fine woolens, synthetics and cottons
(Part 1451 - Box of 100)
(Part 1458 - Box of 500)
Fine For sheer fabrics, very soft materials
(Part1452 -Box of 100)
(Part 1459 - Box of 500)
1.3 BIADES AVAILABLE
The blades come in three grades and in different shapes for
cutting unusual or difficult materials. The three grades available
atei
Z,K-}l.igtr Speed Steel...Most popular blade as it wears well
retaining its cutting edge for a long time.
BK- Carbon Alloy Steel... A qualityblade less durablethanthe
ZKblade but less costly.
TK-Treated HighSpeed Steel...Retains cutting edge verywell.
Used only for hard or abrasive materials such as fiberglass or
heavy denim as it is very expensive.
See back cover for complete list of part numbers of blades
according to size, grade, shape, and quantity.
II. OPERATION
2.1 UNPACKING A NEW MACHINE
During shipment oil may have flowed onto Pulley ,{303 which
can cause sharpener to traverse slowly. Sharpener cycle time
is 1.5 seconds. If longer, oil is causing Pulley to slip. To remove
oil, disconnect power, removeBrake 4342, wipe oil from Pulley
and Crank 4505. Replace Brake.
2.2 TO START
Fill oil cups. Attach Connector A525 to Terminal Pins 4523.
Move switch 4,550 from "off'to "on" (USA) or *O" to "I"
(International).
Caution: 3 phase motor must turn counter-clockwise when
viewed from rear. (FtexiBand against Blade must rotate from
back to front).
2.3 TO SHARPEN BLADE (Figure 1)
Machine should be clear of lay and Presserfoot *A' should be
down on Baseplate *B'. With motor running, move Tripper
Handle "C" to right (facing sharpener) until it latches. Release
it. Sharpener will automatically sharpen entire blade. Repeat if
necessary.

including the following:
This cutting machine is for commercial use only. Read all instructions before using.
DANGER--to reduce the risk of electric shock:
1. Do not install or store this machine in a wet location.
WARNING--Io reduce the risk of btrns, fire, electric shock, or injury to persons:
use machine only for its intended use as a portable cutting machine.
Turn machine to "oFF"(o) before connecting or disconnecting power cord.
Connect this machine to a properly grounded outlet only. See Grounding Instructions.
Always disconnect electrical connector from machine when not using it, before servicing it, or
changing blade.
Do not leave machine unattended while it is connected to power outlet.

SAVE THESE INSTRUCTIONS
GROUNDING INSTRUCTIONS
This machine must be grounded. In the event of malfunction or breakdown, grounding provides a path of
least resistance for electric current to reduce the risk of electric shock. This machine ii equipped with a
Ground Shield surrounding the Terminal Pins; this Ground Shield is designed to be used with a Maimin
Grounded Connector, part #4584 or 4588. See Wiring instructions supplied with the Connector.
D {NGER -- Improper connection of the Maimin Connector can result in a risk of electric shock.
Check with a qualified electrician or service man if the grounding instructions are not completely
understood or if in doubt as to whether the machine is properly grounded.
Do not modifu the Ground Shield provided with this machine.
Use correct wire sizes with the Maimin Grounded Connector.
U.S.A. only: I Phase: Use AWG 1613 SJ, SJT or SJE
3 Phase: Use AWG 16/4 SJ, SJT or SJE
International: I P+N+: Use 3Xl, Omm CEE (2) 6l
' 3 F+: Use 4X1, Omm CEE (2) 61

l. DESCRIPTION
The MAIMIN VARISPEED is designed to operate on AC current. It has a direct current motor
with a permanent magnet field, controlled by an adjustable speed scR drive.
VOLTAGE CONNECTION
Connect only to voltage shown on nameplate.
NAMEPLATE RATINGS
Values are for full load conditions.
Do not use motor for prolonged periods at line currents greater than shown on nameplate.
OVERLOAD PROTECTION
The control box is fused with a time-delay ceramic-tube fuse; S AMP for 120V, 5 AMp for 220V.
Do not use a larger fuse without consulting Maimin.
MOTOR ROTATION
Remove button plug (Part 446Q) from back of housing (part 15235).
Correct rotation is counter-clockwise looking at end of armature. (Bands must rotate away from
blade.) If motor rotates in wrong direction, change by reversing black and white wires on iontrol.
SLOW START
Your control is equipped with a circuit for slow starting and controlled acceleration. The short
delay between the time you turn on the machine and it reaches set speed is normal.
MAGNETS
Avoid dropping or sharp blows to motor. Demagnetizing occurs only with severe overvoltage.
(About 150% normal). Magnets can only be purchased as part of a magnet and shell assembly.

8. BRUSHES
Brushes (ParI 15237) should be inspected periodically to insure unintem,rpted service. Length of
nerv brush is 1.250" (31.75 mm). Minimum operating length is 0.500" (12.7 mm). Life depends on
speed and load. We suggest inspection brushes every 1000 hours.
TO INSPECT BRUSHES:
Remove brush cover (Part 15238) and insulator (Part 15239). Depress brush clip (Part 15241). so
as to disengage tabs of clip and remove. Remove roll spring (Part 15240). Loosen Phillips pan
head screw, remove lug and withdraw brush (Part 15237).
MOTORBEARINGS
Bearings are lubricated for life. Rear motor bearing (Part 403) can be replaced by removing four 8-
32 keep-nuts (Part 857N) and back housing (Part 15235). Using bearing puller, pull bearing off
armature shaft. To remove front bearing, motor must be disassembled. See Motor Disassembly.
After motor is separated from frondhousing, pull bearing offarmature shaft using bearing puller.
MOTOR DISASSEMBLY
In order to disassemble motor, the crank must be removed. Remove sharpener and connecting rod.
Insert handle ofknife key into hole in face ofcrank and tap clockwise until crank loosens on
armature. Disconnect two armature leads (A+ & A-) from control on box (part 4472\.
Remove nut for strain relief (Part 465K) and remove cable with quick disconnects. To remove
back housing (Part 15235) from shell and magnet assembly remove four 8-32 kep-nuts (Part
8s7N),
Pull brushes (Pafi 15237) out and away from commutator so as not to damage them when pulling
armature from shell and magnet assembly (Part 15354).
Wilh rubber or plastic headed hammer tap end of armature until complete motor separates
from front housing
CAUTION; Do not lose wave washer (Part 15f95) at back housirrg.
MOTOR ASSEMBLY
cAUTroN: Avoid pinching your fingers and scarring commutator or wires. slide
commutator-end of armature through magnets by using the edge of the ball bearing to guide
start of insertion.
