SAFETY LABELS

RECEIVING THE MACHINE
1. Any damage that may have occurred during shipping must be reported immediately.
2. Use caution in transporting the machine within your facility. The machine is top heavy.
3. Strap through the two lifting rings located on the top of the main housing of the machine
and lift the machine off of the shipping pallet. Note* the machine has an approximate
shipping weight of 350 lbs. be sure that your lifting mechanisms can handle that load.
4. After the machine has been removed from the shipping pallet, it should be leveled and
bolted to the floor using ½ inch lagging bolts.
5. A qualified electrician should be used to connect the machine to the main electrical
supply; all cables have been prepared so that only the main supply line is all that needs
to be connected to the terminals inside the electrical box. Please consult Tennsmith if
any questions arise during electrical installation.
OPERATION SAFETY
1. Warning! Due to the nature of the machine and the necessity to feed parts by hand
into the machine while it is turning, great care must be followed to ensure that fingers,
hands, and body parts do not come near the forming rolls when in use.
2. Warning! There is also a danger to fingers and hands while the upper shaft is being
set to the proper forming pressure. The upper shaft will move downward towards the
lower shaft. Care must be taken to ensure that hands, fingers, and body parts are
clear of the two shafts will forming pressure is being set.
3. Protective clothing such as hairnets, tight clothing, and tight fitting protective gloves
should be used while operating this machine.
4. Prior to any work being formed, each operator must be thoroughly instructed as to the
proper way to handle and guide the work pieces in a safe manner so that the
necessary safety clearances between the operator and the machine is met.

OPERATION of the MODEL PR16
1. The upper arbor (100) of the PR16 is depth controlled either by either by a crank
handle located on the top the main cast body of the machine or by hydraulic powered
depth selection, depending on which model you have.
2. The lower arbor (101) has in and out horizontal adjustment that is controlled by the
lever handle designated part #132 in this manual.
3. An adjustable material guide part #130 is provided to serve as a stop to guide your
against while operating this machine.
4. The rolls are secured to the end of the shaft via a small circular plate located on the
end of each shaft. An allen wrench is needed to lock and unlock the plate. Be sure
that the power is in the off position when adjusting or replacing the rolls. Also, be
sure that the rolls are properly seated against the shaft and secured with the circular
plate before resuming operation of the machine.
5. Hydraulic Depth Selection Equipped Machines Only! The pressure adjustment
knob (figure 1) is used to set the pressure rating of the hydraulic clamp tension. The
range of the hydraulic pressure is 0 to 2700 psi. The amount of pressure needed will
vary depending upon the material type and thickness, and upon the profile or rolls
being used. The hydraulic pressure will show a 0 reading on the indicator dial until
the top roll engages the material or lower roll. Please consult the factory if you have
any questions regarding the pressure adjustment. The Hydraulic depth selection
machines are also equipped with a depth selection switch (figure 2) that allows you to
jog the upper shaft up or down to engage or disengage the work piece. The proper
depth is determined by material type and thickness being formed. It is advised to use
a scrap piece of the material being formed to determine the proper depth selection
prior to beginning a production run. The machine is also equipped with a directional
selector switch that determines the rotation of the rolls. The switch is located on the
front of the electrical box facing the operator. The 3 positions on the switch are; 1.
Forward 2. Off 3. Reverse. Forward and reverse are engaged by the foot switch
(figure 3) provided with the machine. The 2. position (off) allows the operation to
engage the depth selection and adjust the hydraulic pressure of the machine without
the possibility of the rolls being engaged by the footswitch. VERIFY THAT THE
DIRECTIONAL SELECTOR SWITCH IS IN THE OFF POSITION WHILE SETTING
THE UPPER SHAFT DEPTH WITH THE DEPTH SELECTOR SWITCH.

6. The standard machines have a hand crank adjustment knob located at the top front
of the housing (105) of the machine. The adjustment knob controls the depth either
up or down, of the upper shaft.
7. Each machine is equipped with a lower roll adjustment handle (part 132). This
adjustment allows for the horizontal adjustment of the lower arbor (101) either
towards or away from the operator. This movement is determined by rolls be used
and profile that you are trying to achieve. Figure 4 shows the roll adjustment handle
in detail. The adjustment includes a locking handle that locks and unlocks the lower
roll position. To move the lower roll unlock the adjusting handle and move the knob
under the handle either up or down depending upon the desired position of the lower
roll. If you have any questions regarding this adjustment, please consult the factory.
8. The Material Guide Part (130) is used to serve as a stop for the end of the material to
run against as it is being formed. The guide can be moved either in or out as needed
to confirm the profile being formed. Figure 5 shows the locking screw that locks and
unlocks the material guide.
MAINTENANCE AND LUBRICATION
1. Warning! The power must always be disconnected prior to any scheduled
maintenance of this machine. Turn the power off at the main disconnect and secure
with a safety lock. Service, maintenance and repair should only be carried out by
authorized personnel.
2. Models with the hydraulic depth selection option require a 2-quart capacity oil reserve
located on underneath the main housing. Check the tank monthly to verify that the oil
level is at the lower edge of the filler opening. The oil used at the factory is a T46
Shell Oil hydraulic fluid. Please contact the factory if you have any questions
regarding types and quantity of oil needed for your unit. The picture on the following
page shows the location of the filler opening under the main housing.
3. We recommend that the hydraulic oil be changed once annually. The drain plug
located between the hydraulic motor and the reserve tank. Please consult the factory
if you have any questions regarding this procedure.
4. Industrial grade grease should be applied monthly to the drive gears (part #104).
Again, power must be disconnected before maintenance of this machine. The figure
on the following page shows the top cover (part # 139) removed to show the access
to the drive gears (104).

5. A light film of industrial grade lubricant oil should be applied monthly to all exposed
metal working parts such as the drive shafts (100 & 101). Clean the area of all
excess oil before operating the machine.
6. Replace all covers and protective devices before operating the machine.
PLEASE CONSULT THE FACTORY AT 931-934-2211 IF YOU HAVE ANY
QUESTIONS REGARDING THE SAFETY, OPERATION OR MAINTENANCE OF THIS
MACHINE.
