GUTTER MACHINE SETUP AND OPERATION
The Standard Control package includes a red drum switch (motor control) located on the exit end plate on the right side, and an E-Stop switch located on the right side near the entry end.
The Motor Control drum switch has three positions for electric motor control:
The switch will remain in whatever position it is placed (maintained switch), and will therefore support
continuous operation in both the forward and reverse directions.
Pushing the E-Stop switch will disconnect input power.
GUTTER MACHINE CONTROLS – CE WIRING PACKAGE
The CE Certified control package includes a control box mounted on the right side near the exit end, and an
E-Stop switch located on the right side near the entry end.
The control box features four switches with the following functions:
E-Stop Switch (Red Mushroom Push Button):
Switch Position Action
Pulled/Out On (power)
Pushed/In Off (power)
Once pushed in, the E-Stop Switch key must be turned to pull the switch out and restore power. Because
the Advance button must be pushed to initiate and action, pulling the E-Stop out and restoring power alone
will not initiate any gutter machine action.
Direction Selector Switch (Black Two-Position Switch):
Switch Position Direction
AV Forward
ARR Reverse
This switch determines which direction the gutter machine will run when the Advance Button is pushed. It will
initiate no action by itself.
Mode Switch (Black Three-Position Switch):
Switch Position Mode
CPC Jog
O Off
NORMAL Continuous Operation
The mode switch will determine what will happen when the Advance Button is pushed. In the Jog Mode,
the gutter machine will only advance (forward or reverse) if the Advance Button is held down. In the Off Mode,
the gutter machine will not run. In the Continuous Operation Mode, the machine will start when the Advance
Button is pushed, and will continue to run after the Advance Button is released.
Switch the Mode Switch to OFF to Stop the machine or discontinue continuous operation
Advance (ENCLENCH) Button (Black Spring-Return Push Button):
Switch Position Action
Pushed On
Released Off (Jog Mode) or On (Continuous Operation Mode)
Push the Advance Button to Jog the gutter machine (forward or reverse) or initiate continuous operation (forward
or reverse). The resulting action will depend on the position of both the Mode Switch and the Direction
Selector Switch.
Switch the Mode Switch to OFF to Stop the machine or discontinue continuous operation!
ELECTRICAL VERIFICATION – STANDARD WIRING PACKAGE
Initial Power-Up
*** OBSERVE ALL SAFETY RULES WHEN WORKING WITH ELECTRICITY ***
Inspect all wiring, connections, and electrical components prior to plugging in the gutter machine. Ensure the
Motor Control drum switch is in the OFF (middle) position. Plug the machine in, then re-inspect. Look for
any unusual conditions (broken or burnt wires, smoke, or unusual noise). Immediately unplug the gutter machine
if any unusual conditions exist.
Correct Motor Rotation
First, ensure the E-Stop switch is pulled out. Briefly bump the motor control switch into the Forward
position then back to the Off position. Observe the direction the gutter roll formers rotate. Verify the rollers
will drive material from the entry end to the exit end when the Motor Control drum switch is in the Forward
position. If the gutter roll formers rotate the wrong direction, refer to the appropriate wiring diagram in Section
11 to change motor rotation direction.
Emergency Stop Switch (E-Stop)
Verify the E-Stop Switch functions correctly by first pushing the E-Stop Switch. Attempt to jog the
Gutter machine forward with the Motor Control drum switch. With the E-Stop switch pushed in, the motor should
have no power supply and should not work. Now, place the Motor Control drum switch is in the off
position.
*** CAUTION - IF THE MOTOR CONTROL DRUM SWITCH IS SET TO FORWARD OR
REVERSE AND THE E-STOP IS PULLED OUT, THE MOTOR WILL START TURNING***
Pull the E-Stop out to restore power to the motor and resume normal operation.
Electrical Receptacle
Verify operation of the receptacle using a multi-meter, a light, or a piece of portable electrical equipment
like a power tool. If power tools are used to test the receptacle, ensure the tool is rated for the same voltage
as the gutter machines power source. In addition, if the optional safety circuit is installed, the receptacle will be a
Ground Fault Interrupt type receptacle.
Wiring Diagrams
If the motor, receptacle, or E-Stop switch do not function correctly, the diagrams may be used to troubleshoot the
circuitry. Do not attempt to troubleshoot electrical problems if you are not familiar and comfortable with
basic wiring practices and procedures.
ELECTRICAL VERIFICATION – CE CERTIFICATION PACKAGE
Initial Power-Up
*** OBSERVE ALL SAFETY RULES WHEN WORKING WITH ELECTRICITY ***
Inspect all wiring, connections, and electrical components prior to plugging in the gutter machine. Ensure the
Mode Switch is in the Off (O) position. Plug the gutter machine in, then re-inspect. Look for any unusual
conditions (broken or burnt wires, smoke, or unusual noise). Immediately unplug the gutter machine if any
unusual conditions exist.
Correct Motor Rotation
First, ensure both E-Stop switches are pulled out, and ensure the Direction Selector switch is in the Forward
position. Place the Mode switch in the Jog position (CPC). Briefly press the Advance Button, and observe
the direction the forming rollers rotate. Verify the rollers will drive material from the entry end to the exit
end when the Advance Button is pushed in.
Emergency Stop Switch (E-Stop)
Verify the E-Stop Switches function correctly by first pushing in one of the E-Stop Switches. Attempt to
jog the gutter machine forward with the Advance button. With the E-Stop switch pushed in, the motor should
have no power supply and should not work. Pull the E-Stop switch out. Again, attempt to jog the gutter machine
forward. The gutter machine should now operate normally. Test both E-Stop switches in this manner.
Electrical Receptacle
Verify operation of the receptacle using a multi-meter, a light, or a piece of portable electrical equipment
like a power tool. If power tools are used to test the receptacle, ensure the tool is rated for the same voltage
as the gutter machines power source.
Wiring Diagrams
If the motor, receptacle, or E-Stop switches do not function correctly, the diagrams may be used to troubleshoot the
circuitry. Do not attempt to troubleshoot electrical problems if you are not familiar and comfortable with
basic wiring practices and procedures.
CLEARING THE GUTTER MACHINE
Once correct motor rotation has been established and the electrical verification procedures have been
performed, run the material in the gutter machine out the exit end. If incorrect motor rotation or the electrical
verification procedure backed the gutter profile out of the shear, follow the procedures for re-threading the shear.
DRIVE TRAIN VERIFICATION
After the gutter machine has been cleared, place the Run/Sop switch in the Run position for continuous operation.
Inspect the gears, sprockets, and roller chain for smooth, quiet, unobstructed operation. The drive train
should be adequately lubricated from factory testing. Inspect for proper lubrication and lubricate as
necessary.
GUTTER MACHINE INITIAL SETUP
The gutter machine has been completely set-up, tested, and adjusted at the factory for the coil stock specified upon
ordering. The gutter machine should produce acceptable gutter using the specified coil stock with only
minor or no adjustments.
Initial Setup Inspection
A rapid visual inspection may be performed prior to threading the gutter machine. Check the following items:
• Top/bottom alignment of Station #1, #2, and #3 forming rollers
• Metal clearance between forming rollers throughout the gutter machine
• All rollers in the box assembly are aligned and turn freely
• Clearance between box rollers is set at .047-in (1.19mm)
• Skate Bar/Station #3 top roller alignment
LOADING COIL
Coil Requirements
Use 16-in (406-mm) or 20-in (508-mm) ID coil stock for easy placement on the appropriate spool.
Loading Coil Stock onto the Spool
Loosen the ½-13 hex head bolts in the spool flange and slip it off the center pipe. With the coil standing
upright, slip the spool through the coil, attach the flange snug against the coil stock and tighten the ½-13
hex head bolts.
Loading the Spooled Coil onto the Gutter Machine
Insert the 1" x 24" long solid bar shaft into the spool center pipe. Lifting from the solid bar shaft exposed on both ends of the spool center pipe, use a chain hoist, lift truck, or a ramp to lift the spooled coil into place on the uprights or cradles. Once the spooled coil is resting in place on the uprights or cradles, the spool/coil should be secured in place with upright spool locks or with a cradle center bar.
THREADING THE GUTTER MACHINE WITH COIL STOCK
*** REMEMBER ***
Keep all tools, fittings, hardware, debris or other material away from the feed end of the gutter machine. The coil
stock feeding into the roller sections will act as a conveyor for such foreign items. Extremely serious damage to the rollers will occur should any foreign objects be carried through the machine in such a fashion. Gutter spikes, nails, wrenches, and rivets are typical violators of this rule. Your warranty does not cover such accidents. Irreparable damage can occur to both sets of rollers. Be extremely careful in this matter.
The coil stock should top feed off the spool to avoid forming rippled gutter. Spool stops in the spool mounts should be used to lock the coil during transportation. Loosen these stops before trying to use the gutter machine.
Cutting a Leading Edge on the Coil Stock
For easy threading, clip the corners of the leading edge of the coil.
Entry Guides
Feed the leading edge around the front feed roller and between the entry guide plates. Be sure the metal is directed between the first set of top and bottom rollers and is centered between the vertical bars of the entry guide plates. Allow slack for the rollers to grab the leading edge of the metal. A strong push is usually required to start the coil into the first pair of rollers after the guides.
The entry guides may require a width adjustment prior to attempting to thread the gutter machine. Standing at the
front of the gutter machine and facing the feed rollers, the left side of the gutter machine is to your left. If necessary,
adjust the width between entry guides by moving the Left Entry guide. Use the left-hand inside 3/8-in setscrews
(5/16-in hex wrench) to set the width. Leave about 1/32-in clearance between the coil stock and each guide, but no more than 1/32-in (.79mm).
Threading the Gutter Machine
Place the motor control switch in the forward position and verify the rollers are turning in the proper direction. Push the leading edge of the metal into the forming rollers. From the front end of the gutter machine, watch the first 2 to 3-ft (1/2 to 1-m) feed in, then stop the gutter machine. Verify the leading edge feeds smoothly, free from any obstructions. The power may be disconnected and the top safety covers removed to inspect the feed process. Feed the leading edge up to the shear, then stop the gutter machine. Again, be sure the leading edge feeds smoothly, free from any obstructions.
THREADING THE CUT-OFF ASSEMBLY (SHEAR)
Threading the Cut-off Assembly (Shear)
If you are threading the gutter machine with the cut-off assembly attached, stop the gutter machine with the profile just
short of the cut-off dies. Jog the leading edge up to the dies. Ensure the blade is clear of the die openings, and that no obstructions exist. Carefully advance the metal through the cut-off die openings until approximately 1-in (25mm) extends beyond the cut-off dies.
When to Perform the Threading Procedure
This procedure need be done only on each new coil or after removing the cut-off assembly from the gutter machine for any reason. With metal in the gutter machine and adjustments correctly set, the gutter will feed automatically through the cut-off assembly when the motor control switch is operated.
CUT-OFF ASSEMBLY (SHEAR) OPERATION
Operating the Rack Shear
To operate the Rack and Pinion Shear, slip the cheater bar over the adapter bar on the shear assembly drive shaft. The adapter bar may be bolted to either end of the drive shaft. Rotate the shear handle toward the exit end of the machine 190 degrees. Return the bar to its original position to complete the shear cycle.
Operating the Optional Circular Cam Shear
To operate the optional Circular Cam Shear, first press in the mechanical release bolt located at the top center of the assembly. Rotate the shear handle clockwise (facing the exit end) three revolutions to complete a shear cycle. At completion, the mechanical stop will re-engage.
RUN-OUT STANDS
Setting Up Run-out Stands
Gutter run-out stands must be used when forming gutter in lengths over ten (10) feet (3 meters). The stands (or table) must be level and in line with the gutter machine rollers. Knudson Mfg., Inc. adjustable gutter stands are recommended and are available from the factory. Run-out tables are good for shop use if they have an adequate number of rollers or a non-scratching surface.
Effect on Gutter Profile
If the gutter curves upward, the run-out stands may be set too high. If downward, the stands may be set too low. If the gutter curves to either side, the machine may be tilted in that direction and should be leveled.
LENGTH MEASUREMENTS
Measuring Gutter Lengths
A tape holder attached to the end plate (exit-end) of the gutter machine is built for a 100-ft (30-m) standard steel tape measure. Place a tape in the holder and hook the tape end on the leading edge of the gutter. The tape pays out as gutter rolls out of the gutter machine. Watch the reading on the tape as you run the gutter machine. Use the inside edge of the outside cutter blade as a mark to determine the exact gutter length prior to operating the cutter.
The optional Footage Counter may also be used as a reference to determine part length. Both Imperial and Metric counters are available. The counter functions as a totalizer, measuring the accumulated length of material run through the gutter machine. Part length may be determined by comparing the difference between start and finish values on the counter.
Keep both the gutter machine and the surrounding work area clean and free of dust, dirt and debris. Routine cleaning of the entire gutter machine will help extend the life of all mechanical and electrical components of the gutter machine. In particular, a clean gutter machine and work area will help prevent the presence of foreign objects into the gutter machine, which can most likely damage mechanical components.
