6.0 Installation & Setup
6.1 Inspecting Shipment
This machine has been carefully packed to prevent damage during shipment. However, claims for
damage or loss are the responsibility of the recipient. Inspect all shipments as soon as they are
received. If there is any noticeable damage, note it on the freight bill. Visual and/or hidden damage
must be reported to the claims department of the carrier within 15 days. Contact your dealer if you
need any assistance. Check the contents of the box against the packing list on page 8. Make sure
there are no missing items.
6.2 Uncrating
This machine is lagged to a wood skid and covered with a triple-walled corrugated container. Loosen
the flaps of the carton where they are attached to the skid. When loose, the carton can be lifted
straight up. Remove the side tables and accessory box, which are also attached to the skid. Place
the cutter/skid about where the machine will be positioned and remove the lag screws from the skid.
Remove the lower shipping block holding the counter weight up. It is secured in place with a lag
screw and washers. Remove the upper shipping block, which is also secured in place with a lag
screw and washers. If the upper wood block cannot be removed because the knife bar is in the way,
wait until the machine is powered up for the first time and remove the upper wood block when the
knife bar has been raised under power.
Make sure that both of the rollers, for the counter weight, are riding on the guide shaft. It is possible
that during shipping, one may have moved off of the shaft. The rollers are located on the top and
bottom of the counter weight. The counter weight is located inside the left front enclosure door
behind the clamp cylinder. Make sure if the machine is ever reshipped the counter weight is blocked
up so that there is slack in the counter weight chain and the counter weight does not bounce. The
counter weight should be blocked/ held up with a wood 2x4 piece of lumber 11-5/8” long. This block
needs to be secured in place with a lag screw and washers as shown in figure 2, page 12.
Remove the shipping block securing the paper deflector. This shipping block is wedged between the
bottom of the paper deflector assembly and the mounting pin for the paper deflector extension spring.
The shipping block is held in place by a cable tie. The cable tie and shipping block are accessible
through the left arch access hole by removing the left arch end cover (Figure 3), page 12. If the
machine is ever reshipped, a 1” X 2” piece of lumber (actual size 3/4” X 1-1/2”) 17” long should be
wedged in between the paper deflector assembly and the mounting pin for the paper deflector
extension spring as it was when shipped from the factory.
Before the machine can be run for the first time, the 3/4 NPT plug in the reservoir needs to be
replaced with the breather cap, see section 6.8 Hydraulic Check on page 17.
Save the packing materials.

6.3 Re-Crating and Shipping
Save the packing materials and braces. All packing blocks and hardware should be saved or
reproduced in order to ship the machine again. If the machine is not repacked as it came from the
factory, damage will result when trucked.
Remove the knife before shipping.
Brace the back-end of the table to the skid using a 2x4.
Use a skid larger than the outer tip-to-tip dimensions of the machine.
Block the counter-weight according to page 12, Figure 2 and 3
Remove the hydraulic breather cap and plug with a ¾ NPT plug.
Always lift and transport from the front of the machine. The carton has lifting instructions, so
it must be placed properly on the skid.
Challenge is not responsible for an improperly packed machine. The skid and packing materials are
available for purchase from Challenge.
6.4 Lifting Instructions
Professional riggers should do unpacking, handling, and positioning. If handling or unpacking is a
problem, your dealer or a local trucking facility should be able to supply or recommend a qualified
rigger. This 3750-lb/1701-kg machine should be moved with experienced people and the proper
equipment. Do not risk personal injury or damage by attempting to move machinery with makeshift
equipment or inadequate manpower.
Lifting straps may also be used to lift the machine by placing the straps around the front and rear of the
table. When straps are used in this way, wood blocks must be placed beside the lead screw to prevent
damage, (Figure 4). A bent lead screw will cause the backgauge to bind. The lead screw cover must
also be removed. Do not strap around the lead screw cover.
Figure 4
The backgauge should be positioned all the way to the front of the table and straps placed as close
the machine body as possible. Gently lift the cutter, remove the skid and carefully place the cutter on
the floor.
6.5 Cleaning
Wipe down the table and bare metal surfaces with a non-flammable solvent such as CRC or blanket
wash. The table surface is cast iron and will rust if left unprotected. Coat the table with a non-
abrasive wax. A Cutter Care Kit, p/n 16077, with cleaner and wax, is available thru your Authorized
Challenge Dealer. The protective film on the console may be removed. Never clean console with
petroleum based solvents. Damage will result. See also Cleaning under Maintenance Guide on
page 37.

6.6 Assembly: Standard
Unless otherwise specified, the only items that have been disassembled for shipping are the
extension side tables. To assemble the table extensions, follow the procedure below.
NOTE: Assembled side tables are awkward and heavy. Use two people to attach the side tables.
1. Install the side table supports. Each support is attached to the frame with two (2) bolts and
washers. (Mounting bolts are shipped installed in the frame - remove them to install
supports.)
2. Thread the 1/2-13 hex nut, packed with the machine, onto the 1/2-13 X 2-1/4 hex bolt. Screw
the bolt into the nut welded on the table support.
3. Assemble the side table backs to the table surfaces. The extension table bolts and hex nuts
are packed inside the tool kit box. Tables are installed with the clearance hole for the knife
gib adjusting screws towards the middle of the cutter. Make sure the right hand side table
back plate is bolted onto the right hand side table, and the left hand side table back plate is
bolted onto the left hand side table.
4. Have one person hold the assembled side table in position while the other aligns the holes
and threads the mounting bolts with washers. (Mounting bolts are shipped installed in the
side of table- remove them to install tables.)
5. Use a 9/16” socket and extension to lightly tighten the mounting bolts, then tap the extension
table up or down with a rubber mallet until it is flush with the main table. Run a straight edge
or sheet of paper over the seam to check the fit. Make sure your stock will not catch on the
seam.
6. Locate the leveling bolt that was threaded into the welded nut on the table support in step 2.
You may have to loosen the mounting bolts a little to allow enough play to level the table.
When the extension tables are leveled and the surface joints even, tighten the mounting bolts
securely. Make sure the 1/2-13 hex nut, threaded on the leveling bolt in step 2, is tightened
to prevent the leveling bolt from loosening.
7. The tables are powder coated and need only be wiped down with a dry cloth. DO NOT apply
solvents or abrasive cleaners to extension table surfaces. They may cause discoloration or
scratches.
6.7 Assembly: Table Out
If your cutter has been shipped knocked-down, it is even more important to have a rigger or qualified
personnel with the right equipment to position and assemble your cutter.
Your cutter will arrive in two crates. One contains the arch/base assembly. The second, accessory
box contains the parts, accessories, and table. Reassemble as follows:
1. Remove the crate from the arch/base assembly.
2. Remove the accessories from the accessory box.

6.8 Hydraulic Check
When the machine is shipped, the breather cap should be replaced with a 3/4 NPT plug. This is how
the machine is shipped from the factory. Before the machine can be run for the first time the NPT
plug needs to be replaced with the breather cap. Access the plug behind the small cover on the
hydraulic power unit cover behind the machine.

The hydraulic reservoir is filled with 15 gallons of grade #46 hydraulic oil at the factory. The fluid level
should be checked before operation, and periodically during normal operation. The reservoir is
located behind the cutter, beneath the table (). The hydraulic tank has a breather cap that
can be removed for changing the oil and checking the oil level. The reservoir should be kept full at all
times. Fill the reservoir so that the oil level is 3/4” below the top of the inside of the hydraulic tank.
NOTE: DO NOT OVERFILL. Overfilling may cause leakage when the machine is hot.

6.9 Power Hook-Up
SHOCK HAZARD! Always disconnect power at main power panel
before working on the cutter. Lock it out to prevent accidental power up. See Power Lockout
Procedure (page 5).
For satisfactory operation, be sure that your cutter is wired for the correct phase and voltage and has
adequate power. The correct electrical specifications for your machine are shown on the serial plate.
Check the machine serial plate before connecting the power. For future reference, transfer this
information to the front cover of this manual.
Watch Setup Voltage- Inadequate power to the cutter can be a major source of problems. Too
many machines on the same circuit will reduce the power to each machine. Inadequate voltage will
frequently cause overheating, loss of power, and in extreme cases, failure to operate. Test your
voltage when the shop is at actual working levels. Challenge recommends a dedicated line with a
lockable disconnect to provide adequate power for this machine.
Important: You must have an adequate size circuit and heavy enough wiring for this machine. The
circuit size should be a minimum of 20% greater than the amperage rating on the machine
nameplate. If a wire is run over 75 feet (23 meters), the next size wire should be used. Check local
electrical codes.

6.10 Three Phase Hook-Up
The power source is connected to the cutter through the bottom of the power panel (right hand side).
A main power control switch and power cord providing the machine with power is the responsibility of
the customer and should be set in accordance with the local electrical code.
1. DISCONNECT AND LOCK OUT THE POWER (See Power Lockout procedure, page 5)
2. Thread the power cord through a conduit connector into the power panel.
3. Fasten the ground lead to the ground terminal lug (Figure 11).
Figure 11
4. Fasten the three power leads to the three terminals of the main power terminal block- L1, L2,
& L3.
5. Close the electrical panel doors and latch them. Unlock the main panel and turn on the
power. Turn on the main power disconnect switch located on the front face of the table.
6. Press both cut buttons simultaneously to activate the motor and check to make sure it is
turning the same direction as the arrow on the motor casing.
If it isn’t, disconnect the power and exchange any two leads (L1, L2 or L3) of the power cord as in
Figure 12, page 20. The motor will now turn the correct direction.

6.11 False Clamp Plate
ALWAYS disconnect the power and LOCK IT OUT before installing or
removing the false clamp plate. NEVER attempt to install or remove the false clamp plate while the
machine is running. Remove all tools and stand clear when reconnecting power.
To prevent marking on pressure sensitive jobs, a false clamp plate has been included (installed) with
your machine. This plate attaches to the bottom of the clamp. It is secured from the front of the
cutter with three set screws that clamp against the mounting rods on the false clamp plate.
1. DISCONNECT THE POWER AND LOCK IT OUT (See Power Lock-Out Procedure, page 5)
2. Position the false clamp plate under the clamp. The locator pegs should be positioned to the
rear of the cutter and are set into holes in the bottom of the clamp.
3. With a 1/8" Allen wrench, back off the setscrews in front of the clamp and raise the plate up to
the bottom of the clamp. It may be necessary to bring the clamp down slightly with the foot
pedal in order to access the far left setscrew. Raise the false clamp plate evenly or it will
have a tendency to bind. When the plate has been raised into position and is flush with the
bottom of the clamp, tighten the setscrews to hold the plate in position.
4. Make sure that all tools have been taken off the cutter table, reconnect the power, and turn
on the power.
NOTE: The cutter cannot make cuts smaller than 2-5/8" (66.7 mm) with the false clamp plate
installed.
