5. Reinstall the roller shafts and hitch pins.
6. Place the pipe over the bending die.
OPERATION
To bend a pipe:
1. Insert the pump handle bar into the socket on
the tube bender shown in Figure 1.
Note: To account for pipe shortening dur-
ing the bend, make sure the pipe extends
beyond the rollers (Figure 5) and, for short
pipe, set the rollers closer together, as shown
in Figure 6.
2. Choose the proper size bending die and slip it
on the end of the ram as shown in Figure 3.

Die

Figure 5. Pipe installed beyond rollers to
account for pipe shortening during the bend.
3. Choose an angle to bend your pipe. To make
a 35-45˚ bend, place the rollers between the
far outside holes on the frame. To make a
90˚ bend, place the rollers between the holes
closest to the ram. Placing the rollers fur-
ther inside the frame increases the bending
angle.
4. To move the rollers, remove the hitch pins
and roller shafts (Figure 4), and place the
rollers between corresponding holes on each
side of the frame.

•
Pipes bent past 90˚ will flow into the bending
die, making the pipe hard to remove after
bending. Greasing the inside of the die will
make this removal easier, or switching to a
larger die for bending the last few degrees
will eliminate this difficulty.
Never use a cheater pipe extension on the
hydraulic pump handle. Failure to comply
may result in personal injury.
7. Make sure the release valve is closed, then
use the pump handle bar (Figure 7) to
advance the die and bend the pipe.
MAINTENANCE
•
The Model G9017 and G9018 are basi-
cally maintenance free. However, the oil level
should be kept constant at about 2.5 pints of
quality hydraulic oil.
•
•
Too much oil will force the surplus oil to leak
from the bottle jack fill plug (Figure 8), caus-
ing a mess.
Pump
Handle
Bar
Not enough oil will cause loss of power.
To add oil:
1. Set the tube bender upright, retract the piston
rod fully and remove the fill plug (Figure 8).
Release Valve
Figure 7. Operating pump and release valve.
8. When you are finished with your bend, release
the pressure by opening the release valve
and the ram will automatically retreat.
Operation tips and tricks:
•
If the ram reaches the end of its stroke
but still has not completed a desired bend,
release pressure just enough to remove the
pipe. Set the rollers either one or two holes
farther in to finish the bend.
Fill Plug
Figure 8. Fill Plug.
•
We recommend making templates of accu-
rate 45˚ and 90˚ angles. Compare these
templates to an almost finished pipe so you
do not over- or under-bend the pipe. Using
templates will speed up your work.
2. Fill the bottle jack to the level of the fill plug
hole and replace the fill plug.
3. Place the tube bender in its operating posi-
tion, fully extend the piston rod, then retract
the rod to expel air in the bottle jack.
•
•
If you pass the 45˚ angle mistakenly, you
can sometimes reverse the pipe and slightly
press it enough to reach the required 45˚.
4. Remove the fill plug and repeat Steps 2 & 3
until all of the air is expelled.
Bending any angle may thin and stress the
walls and narrow the center of the pipe. If
you need to make bends more than 100˚, we
recommend heating the pipe during bending.
Generally, heat weakens metal, but it will
allow it to bend more freely.
If you need additional help with this procedure,
call our Service Department at: (570) 546-9663.
