JOB SITE PREPARATION
TRANSPORT THE LIFTER
Always turn the fuel shutoff valve to the OFF position when
transporting or storing the vacuum lifting system.
When transporting the lifter, always securely attach it to the
cradle with the proper hardware.
NOTE: Never transport or store the lifter by setting the pad
directly on the trailer or the ground. Damage to the seal may
result.
PREPARATION OF THE LIFTER
CONNECT THE HYDRAULIC HOSES
We recommend the hydraulic hoses from the vacuum lifting
system be connected to the hydraulic lines used for the
bucket cylinder on the excavator.
NOTE: Always clean the area around the hydraulic fittings
and connections of dirt and debris before connecting or
disconnecting any hydraulic lines or components. Hydraulic
rotators are sensitive to dirt and foreign debris and will be
damaged if dirt is allowed in the hydraulic system.
The hydraulic hoses supplied are extra long to allow them to
be connected to a wide variety of machines. Be sure to secure
the extra hose so not to interfere with the rotator.
1. There are flow control valves (Fig. 1-1, 1) installed on
the hose fittings. There is a flow diagram embossed on
the flow control valve which shows the direction of flow.
2. If the diagram is illegible, there is usually an inverted
dot next to the knob on the flow control valve. The dot
goes toward the excavator and the knob will be toward
the vacuum lifter.

3. Make sure the hoses from the excavator are connected
with the flow in the correct direction.
4. Connect the hoses to the flow control valves. Do no
over-tighten the fittings. Over-tightening will cause
damage to the fittings.
5. Route the hoses along the stick. Clamps are provided
that can be tack-welded to the stick to route and
support the hoses. When securing the hoses, allow
ample slack for hose movement to avoid binding or
pinching.
ATTACH TO THE EXCAVATOR
1. Inspect the adaptor and pin to make sure the proper
pin, bushings, and spacers are used.
2. Inspect the adaptor, pin, bushings, and spacers to
ensure proper fit.
3. Attach the adaptor to the excavator arm using the pin
(Fig. 1-2, 1). Use the correct spacers (Fig. 1-2, 2) to
center the arm between the adaptor.
Fig. 1-2
4. Apply grease to the pin, where applicable, daily to
ensure proper lift functions and smooth movement.
ADJUST ROTATION SPEED
Rotation speed should be slow to maintain control and
operate the vacuum lifter safely.
The flow control valves (Fig. 1-1, 1) on the hydraulic fittings
are “one way open – other way restricted” type. They can be
adjusted to increase or decrease the rotation speed.
1. For initial start-up, turn the valves clockwise all the
way to close them. To open the valves, turn them
counterclockwise one complete turn. Make sure both
valves are adjusted equally.
