Testing Handle Operation:
Briefly test press operation as follows
BEFORE using. With handle on the release
valve turning clockwise or counter clock wise
allows the hydraulic jack to be raised apply
pressure and lowered reduce pressure. To
raise the jack, twist handle clockwise until
it is firm. Do not force or tighten beyond
this point. Take handle from release valve
and place in handle base. Pump handle a
few times to raise the jack about halfway.
If jack does not begin to rise after a few
pumps, check to make sure the release
valve is tight. With hydraulic jack raised,
place handle on release valve twist handle
slowly counterclockwise to lower jack. A
normal hissing sound may be heard as jack
lowers and pressure in hydraulic cylinder is
released.
Using the Pipe Bender:
This hydraulic pipe bender comes with eight
bending die’s to allow for wide variety of
pipe diameters to be bent. The pipe bender
is designed to bend heavy water pipe and
galvanized pipe 13 mm. through to 76 mm.
1.
Place the pipe bender on a smooth
surface and clamp or bolt into position.
2. Select the correct die for the diameter of
pipe to be bent. The wrong die with cause
the pipe to kink or crease.
3.
Adjust the guide rollers to the desired
distance to achieve the angle of bend
required.
4.
Insert the pipe into pipe bender - for large
diameter or long lengths of pipe two
people are required one to balance the
pipe and the other to operate the pipe
bender.
5.
Turn jack handle completely clockwise on
the release valve. Place handle in sleeve
and slowly pump handle until die pushes
the pipe is just firm against the guide
rollers.
6.
Inspect position of pipe, die, guide rollers
and free ends of pipe will not foul or
impact on anything or anyone.
7.
Pump handle until pipe bender has
completed the required operation. Pay
attention to work piece position as pipe
bender is applying pressure to be sure
there is no danger of slipping off or
forcing out of the work piece.
8.
If pipe starts to kink or crease is may
help to fill the pipe with sand and securely
cap both ends.
9.
SLOWLY turn hydraulic ram release valve
counterclockwise to release pressure. Be
aware that the work piece may move
when pressure is released.
valve counterclockwise to release
pressure. Be aware that the work piece
may move when pressure is released.
Warning:
The hydraulic pipe bender is not a vice and
no work should be undertaken on the work
piece while being held by the pipe bender
failure to comply with this instruction
creates a potentially hazardous working
environment. Do not move the pipe bender
wherever practical the press should be
bolted to the ground. Never place any part
of your body through the frame or under any
of the moving parts. The forces applied by
this pipe bender are large if the die or guide
rollers are not properly installed excessive
forces can be generated which may lead to
property damage or personal injury.
Maintenance and Storage
Important Note:
When adding or replacing oil, always use a
good grade Hydraulic Oil. Avoid mixing types
of oil. DO NOT use Brake Fluid, Alcohol,
Glycerin, Detergent, Motor Oil or Dirty Oil,
Improper fluid can cause serious internal
damage to hydraulic ram.
Adding Oil:
With ram fully lowered & on level surface,
remove Air Vent Valve. Oil level should be
approx 12 mm below valve hole. If low, add
oil as needed then close air vent valve.
Replacing Oil:
For better performance & longevity, replace
oil supply once a year. To drain oil, open Air
Vent Valve and loosen the release Valve by
turning handle counterclockwise. BE VERY
CAREFUL not to permit dirt or foreign
matter to get into the system. Close release
valve by turning handle clockwise, fill with
good grade Hydraulic Oil close Air Vent
Valve wipe away any spilt fluid. Test
hydraulic ram before applying a load.
Cleaning:
Hydraulic jack should be wiped clean with
soft cloth only. Do not use gasoline,
kerosene, or other such solvents or any
abrasive cleanser as cleaning agents and
solvents will cause deterioration of the
hydraulic seals.
