COMPONENTS DESCRIPTION
1. Safety Cap
Warning! Pinch point. The safety cap is made of plastic and must be kept in place during operation in order
to prevent serious injury.
2. Blade lever
Due to the optimal lever action, the blade lever enables cutting without effort. After each cutting operation the
blade lever must be returned to its topmost position until it locks.
3. Blade locking device
The blade locking device secures the blade in its top position. A cutting operation can only be carried through
when the front safety guard is in the down position releasing the locking device.
CAUTION: The blade locking device is controlled and connected with the front safety guard and the blade
lever. You can open the front safety guard only when the blade lever is in its starting point.
4. Blade
Made of high carbon, quality steel. A sharp blade is important for the best performance.
WARNING! The blade is sharp. Use extreme caution when working with or near the blade.
5. Blade fastener
The blade fastener consists of 5 screws used to position the blade after cutting stick rotation or blade replace-
ment.

6. Cutting stick
Made of tough plastic, the cutting stick is exchangeable. It may be used two times on each side (total 8 times).
7. Front safety guard
The front safety guard must be lowered before each cutting operation. Only then will the blade locking device
be released. The front safety guard can be reopened only when the blade lever is locked in the top position.
WARNING! DO NOT disassemble or make the front safety guard inoperative for any reason. Serious
injury may occur.
8. Clamping wheel
For pressing and holding the paper stack to be cut.
P
Q
Turn the clamping wheel clockwise to clamp the paper stack.
Turn the clamping wheel counterclockwise to release the paper stack.
9. Cover
The cover is attached to the machine with four screws. Disassemble only in case of blade change or mainte-
nance. Before removing the cover, first remove the safety cap.
10. Blade adjustment
The blade can be adjusted slightly by using the adjustment screw.
×
Ø
Turn to the left (+): Adjust blade downward.
Turn to the right (-): Adjust blade upwards.
Max. adjustment approx. 2mm
Note: A blade which is adjusted too deeply does not only damage the cutting stick but the blade itself. Optimal
adjustment occurs when the last sheet is cut accurately.
11. Back Gauge Crank
The back gauge crank is indirectly connected with the back gauge. Connection is made by a slight push of the
crank toward the machine. The connection is released when pulling the crank away from the machine.
P
Q
Turn the back gauge crank clockwise: the back gauge moves towards the blade.
Turn the back gauge crank counterclockwise: the back gauge moves away from the blade.
The scale behind the back gauge crank serves for fine adjustment of the back gauge. Use the scale to set the
back gauge when precision cuts are needed. One full turn of the crank represents one centimeter movement
of the back gauge. The numbers on the dial represent millimeters and can be accurately set within .5mm incre-
ments.
12. Back Gauge
Operates with the back gauge crank. Adjusts the paper stack to the desired cutting size and for exact parallel cuts.
13. Side gauge with scale
Increments in millimeter, centimeter, and inch. Used for setting the back gauge to the desired paper size.
14. Stand
The stand is made of steel and is standard equipment with the chassis.
15. Light switch
When the light switch is on, a bright line will be visible on the paper stack to indicate the path of the blade.
16. Paper alignment guide
The paper alignment guide aligns the paper on the left side of the cutter. Made of steel.

INSTALLATION
The grip of the blade lever (2), clamping wheel (8), and back gauge crank with screw (11) are packed sepa-
rately in a box with the machine. Please install these parts right away. The chassis and stand of the machine
should to be connected as follows:
1. Set up the legs in a way that the 4 threaded pins point upwards.
2. Assemble the stands by matching the color label on each corresponding part.
3. Place the chassis onto the assembled machine stand.
4. Fit the washer over the threaded pins and tighten the hexagonal nut using a 13 m/m wrench.
5. Fit two batteries (size D) into the battery holder on the underside of the chassis.
OPERATION
Do not attempt to operate the 620RC until you have read and thoroughly understand this manual. The
following procedure should be followed when loading, cutting, and unloading paper from the 620RC.
1. Make sure the safety cap is in place and raise the blade lever until it is locked in its top position.
2. Lift the front safety guard and place the paper stack beneath the blade from the front of the trimmer. Push
the paper stack along the paper alignment guide until it comes to rest squarely against the back gauge and
side gauge with scale.
3. Push the back gauge crank toward the cutter to engage. Turn the crank handle clockwise to bring the back
gauge toward the blade until the desired paper measurement is reached. Use the fine adjustment scale
behind the back gauge crank to insure accurate measurement to within .5mm.

4. Release the back gauge crank (away from cutter), so that the unintentional movement of the back gauge
can be prevented.
5. Turn the clamping wheel clockwise to clamp the paper stack tight. Excessive clamp pressure may cause
the stock to be creased. The use of waste sheets above and below the stock to be cut is a common pro-
tection method used to keep the finished stock from being marked or creased. If additional clamping pres-
sure is required the blade may need to be sharpened. Continuing to cut with a dull blade may cause severe
damage to the cutting mechanism or handle.
6. Lower the front safety guard completely to disengage the blade locking device.
7. Use both hands to bring down the blade lever to make the cut. When the cut is complete, move the blade
lever to its top position until it locks.
8. Turn the clamping wheel counterclockwise to release the paper stack. Lift the front safety guard and remove
the paper stack from the cutter.
BLADE SHARPENING
Dulling of the blade is a natural occurrence and is determined primarily by the type of material being cut. Blade
life with normal paper is approximately 600 cuts (tested in maximum capacity). This will vary for different types
of paper. Many paper products today are made of re-cycled materials and can be very abrasive to the blade.
If it becomes increasingly more difficult to cut paper, the cut is rough, or if excessive clamp pressure is required
to hold the stack, then it is time to sharpen the blade (see page 7). Always keep a spare blade on hand to use
while you send out the dull one to be sharpened by a qualified blade sharpener or machine shop.
WARNING! The cutting edge of the blade is extremely sharp. In order to reduce the possibility of
injury, the blade change should be executed by one person and the blade must be handled with the
utmost care. Please follow the blade replacement instructions exactly.
CUTTING STICK
Gradual wearing of the cutting stick is normal during machine operation. As a groove is formed in the stick by
the cutting action of the blade, the blade may not completely cut through the bottom sheets of the stack. When
this condition occurs, rotate the cutting stick, or replace, if necessary. The design of the Model 620RC cutting
stick allows rotation to eight cutting locations. (The stick may be rotated to four surfaces and reversed from end
to end.) To rotate the stick proceed as follows:
1. Raise the blade lever until it is locked in its topmost position. Raise the front safety cover. Open the paper
clamp by turning the clamping wheel counterclockwise until it stops.
2. A hole in the cutting stick fits over a pin in the left side of the channel beneath the clamp to hold the cutting
stick in place. Carefully lift up the right end of the cutting stick.
3. Place a flat tip screwdriver under the raised end of the cutting stick and slide it under the length of the stick
to completely remove it off the pin and from the channel.
4. Rotate the stick to a new surface and place it back into the channel. Make sure the hole in the end of the
cutting stick fits around the pin in the channel. When all four surfaces have been used, reverse the stick end
to end and repeat the rotation process as needed. Replace the stick when a correctly adjusted new, or
resharpened blade will no longer cut through the bottom sheet of a stack and all surfaces have been used.
Note: When the cutting stick is changed, the blade must be readjusted. A blade which cuts too deeply dam-
ages not only the cutting stick but the blade also. Adjust the blade as described on page 8 (steps 18-21).
LUBRICATION
The mechanical components of the cutter require periodic lubrication depending upon cutter use. Before lubri-
cating, these parts should be cleaned of paper dust and old deposits of oil and grease.
MAINTENANCE
Check all screws on moving parts periodically (or after every 200 cuts) to insure they have not loosened during
transportation or with continued use. The on-schedule maintenance will prolong the life of each part and pre-
vent possible down-time.
