DLR-6/6P Low-Rise Scissor Lifts 9P/N 5900254 — Rev. A — September 2020
Select a Site
Keep the following in mind when selecting a site for your Lift:
•Enough space. Make sure there is adequate space on all sides, plus enough space
above for
the Vehicles you will be raising. Do not install the Lift under low-hanging obstructions. See Check
Clearancesfor more information.
•Power Unit Location. The DLR-6 Power Unit Stand can be installed on either side of the Lift,
close enough for the Hydraulic Hose to reach. The DLR-6PPower Unit is installed on a Portable
Stand, which can be easily moved to the desired location on either side of the Lift within reach of
the Hydraulic Hose. Operators
must always have a full, unobstructed view of the Lift.
•Hose Cover. The DLR-6 comes with a Hose Cover that you can anchor to the ground; it is
54 in / 1,372 mm long. If you plan to use the Hose Cover, make sure to leave enough room
between the Power Unit and the Lift.
•Operator. The operator
must have a full, unobstructed view of the Lift and the Vehicle on it when
raising and lowering Vehicles.
•Longitudinal Shift. When you raise the Lift, the geometry of the scissor arms moves the
Platforms up at an angle. The amount of longitudinal shift for the DLR-6/6P is approximately 14
inches. Refer to About Longitudinal Shift for more information.
•Check for overhead obstructions. The site must be free of overhead obstructions.
•Floor. Do not install or use this Lift on any asphalt surface or any surface other than concrete.
•Concrete specifications. Do not install the Lift on or within 6 in / 152 mm of expansion seams
or cracked or defective concrete. Make sure the concrete is at least 4.25 inches thick, 3,000 psi,
and cured for at least 28 days (if newly poured). Make sure the floor is defect-free, dry, and level.
⚠WARNING Do not install the Lift on a surface with 3° of slope or more. A 3° degree or greater
slope makes the Lift less secure, possibly causing Vehicles to fall, which could lead
to property damage, personal injury, or even death.
•Power. You will need a 115 VAC or a 230 VAC power source near the Power Unit. The Power
Unit ships configured for 115 VAC, but it can be reconfigured to operate on 230 VAC Power. See
Reconfigure the Power Unit to 230 VAC for more information.
•Operating temperature. The Lift is designed to be used between temperatures of 41º to 104ºF
(5º to 40ºC).
•Outdoor installation. The Lift
cannot be installed outside. It is for indoor use only. If you have
the DLR-6P, you can move it outside and use it outside temporarily; make sure to keep it
completely moisture free while it is outside.
•Second floor installs. Do not install the Lift on a second floor or elevated floor without first
consulting the building architect and getting their permission.
•Dress properly. Always wear protective gear when installing the Lift. Leather gloves, steel-toed
work boots, eye protection, back belts, and hearing protection
are mandatory . Do not wear
loose clothing or jewelry; contain long hair; keep hair, clothing, and gloves away from moving parts.
⚠WARNING You must wear OSHA-approved (publication 3151) Personal Protective Equipment
at all times when installing the Lift.

DLR-6/6P Low-Rise Scissor Lifts 10 P/N 5900254 — Rev. A — September 2020
About Longitudinal Shift
When you raise a Vehicle on the DLR-6/6P, the Vehicle goes up; it does not go straight up.
Instead, the geometry of the scissor arms moves the Platforms up at an angle (called longitudinal shift),
towards the Hinged Ramp end of the Lift. The amount of longitudinal shift for the DLR-6 and the
DLR-6P is approximately 14 in / 356 mm.
Longitudinal shift is always in the same direction, towards the Hinged Ramp end of the Lift, no matter
which way the Vehicle is facing.
Vehicle not shown. Not necessarily to scale. Not all components shown.

DLR-6/6P Low-Rise Scissor Lifts 11 P/N 5900254 — Rev. A — September 2020
Check Clearances
For safety purposes, a certain amount of clear space around the Lift is required .
Additional space on Hinged Ramp side for longitudinal shift. Not necessarily to scale. Not all
components shown.
Unpack and Locate the Lift
Using an appropriate lifting device (Shop Crane or Forklift, for example), move the Lift off of the bottom
of the shipping container and to its permanent location (in the case of the DLR-6) or its starting location
(in the case of the DLR-6P).
⚠CAUTION Use caution when taking the Lift out of its shipping container. You do not want to
damage the unit, misplace the components, or get hurt.

DLR-6/6P Low-Rise Scissor Lifts 12 P/N 5900254 — Rev. A — September 2020
Assemble the Portable Stand (DLR-6P only)
The DLR-6P comes with a Portable Stand to hold the supplied Power Unit.
Assemble the Portable Stand as shown below; securely tighten all connections.
Attach the Power Unit to the Portable Stand (DLR-6P only)
Once you have assembled the Portable Stand, attach the Power Unit.
Attach the Power Unit using the included M8 x 25 Bolts, M10 Washers, and M8 Nuts.
Important: Do not connect the Power Unit to the Hydraulic System or power source at this point
of the installation; those connections will be made later.

DLR-6/6P Low-Rise Scissor Lifts 13 P/N 5900254 — Rev. A — September 2020
Assemble the Tow Cart (DLR-6P only)
The Tow Cart, which is used only with the DLR-6P, lets you move the Lift to other locations.
The following drawing shows how to set up the Tow Cart.
Raise the Platforms Off the Base
You need to raise the Platforms off the Base to access two of the three Anchor Bolt holes
(Anchoring for DLR-6 only).
Be sure to leave the Lift engaged on a Safety Lock when you
raise it.
⚠WARNING We strongly recommend using at least two people to lift the Platforms off their
Bases: one person to hold down the Base and one person to operate the Forklift or
Shop Crane to raise the Platforms. Use care when raising the Platforms off
the Base
.
To lift the Platforms off the Base:
1. Use a Forklift or Shop Crane to raise the Platform off of its Base.
Make sure to hold down the Base while you raise the Platform.
Tip Once the Platform and Base are separated by more than half an inch (~13 mm), you
can put industrial slings (straps) around each end to continue raising the Platform off
the Base.
2. When the Platform gets above the top Safety Lock, lower it back down onto the top Safety Lock.
Do
not raise the Platform a random distance; leave it on the top Safety Lock.
⚠WARNING Do not continue with the installation without first confirming that the Lift is securely
engaged on a Safety Lock.

DLR-6/6P Low-Rise Scissor Lifts 14 P/N 5900254 — Rev. A — September 2020
About Embedment
Anchor Bolts (also called Wedge Anchors) get their holding strength from how far down into the Hole
the Anchor Bolt is installed (called embedment) and how forcefully the Expansion Sleeve presses into
the Concrete (based on how much torque is applied).
To get enough embedment, you have to understand Effective Embedment, which means the location
in the Hole where the Expansion Sleeve presses into the Concrete. This is where the Anchor Bolts
create holding strength; the further down into the Hole, the greater the holding strength.
(The technical definition of Effective Embedment is the distance from the surface of the base material
to the deepest point at which the load is transferred to the base material; the “base material” in our
case being the Concrete into which the Anchor Bolts are being installed.)
Some people confuse Effective Embedment with Nominal Embedment, which is how far down into the
Hole the bottom of the Anchor Bolt is.
As shown below, the two are not the same. Nominal Embedment is
not where the load is transferred
to the base material, Effective Embedment is.
Not necessarily to scale.
The Anchor Bolts shipped with your product may have letters stamped into their tops, indicating their
length.
For example:
•4.75 in / 120 mm Anchor Bolts are stamped with a G.
•6.3 in / 160 mm Anchor Bolts are stamped with a J.

DLR-6/6P Low-Rise Scissor Lifts 15 P/N 5900254 — Rev. A — September 2020
Anchor the Bases (DLR-6 only)
The Lift has three holes in the Base for anchoring it. Anchoring provides stability for the Lift.
Give a lot of thought to where you want the DLR-6
before anchoring it: once the Lift is
anchored, it is extremely difficult to move
.
Concrete specifications are:
•Depth: 4.25 in (108 mm) thick
•PSI: 3,000 PSI, minimum
•Cured: 28 days, minimum
Anchor Bolt specifications are:
•Length: 4.75 inches
•Diameter: ¾ inch
•Effective embedment: 2.75 inches, minimum
•Anchor torque: 85 – 95 pound feet
(do not torque less than 80 or more than 105)
Anchor Bolt holes must be at least 6 in / 152 mm away from expansion seams or cracked Concrete.
⚠WARNING Only use the factory-supplied parts that came with your Lift . If you use
parts from a different source, you void your warranty and compromise the safety of
everyone who installs or uses the Lift.
To anchor the Lift:
1. Make sure you are wearing OSHA-approved (publication 3151) Personal Protective Equipment:
leather gloves, steel-toed work boots, back belts, hearing protection, and ANSI-approved eye
protection (safety glasses, face shield, or goggles).
2. Make sure the Lift is in the desired location.
3. If it is not already, raise the Lift as high as it will go, then engage it on the top Safety Lock.
Refer to Raising a Vehicle for lifting instructions.
4. Using the holes in the Base as guides, drill each hole 4 in / 101 mm deep.

DLR-6/6P Low-Rise Scissor Lifts 16 P/N 5900254 — Rev. A — September 2020
Note: If you prefer, you can mark the Anchor Bolt hole locations, move the unit out of the way,
drill the holes, and then move the unit back into position.
When drilling, go in straight; do not let the drill wobble.
Use a carbide bit (conforming to ANSI B212.15).
The diameter of the drill bit
must be the same as the
diameter of the Anchor Bolt.
5. Use a wire brush and a vacuum to
thoroughly clean each hole.
You can also use a hand pump or compressed air. Make
sure to thoroughly clean the holes.
Do
not ream the hole. Do not make the hole any wider
than the drill bit made it.
6. Make sure the Washer and Nut are in place and flush with the top of the Bolt, then insert the
Anchor Bolt into the hole.
7. Hammer or mallet the Anchor Bolt the rest of the way down into the hole.
Stop hammering when the Washer is snug against the Base.
Use a hammer or mallet to get the Expansion Sleeve
through the Base and down into the hole.
Even using a hammer or mallet, the Anchor Bolt should
only go into the hole part of the way; this is normal. If the
Anchor Bolt goes all the way in with little or no resistance,
the hole is too wide.
Once past the hole in the Base, the Anchor Bolt eventually
stops going down into the hole as the Expansion Sleeve
contacts the sides of the hole; this is normal.
8. Torque each Nut
clockwise to the recommended installation torque, 85 – 95 pound feet (do not
torque less than 80 or more than 105), using a Torque Wrench.
Wrenching the Nut forces the wedge up, pushing out the
Expansion Sleeve and pressing it tightly against the
Concrete.
Important: Do
not use an impact wrench to torque
the Anchor Bolts.

DLR-6/6P Low-Rise Scissor Lifts 17 P/N 5900254 — Rev. A — September 2020
Anchor the Power Unit Stand (DLR-6 only)
The DLR-6 comes with a Power Unit Stand to hold the supplied Power Unit; it can be on either side of
the Lift. The Power Unit Stand
must be anchored.
Not necessarily to scale. Not all components shown.
To anchor the Power Unit Stand:
1. Select an appropriate site for the Power Unit Stand.
2. Locate the Power Unit Stand and two Anchor Bolts (¾" wide, 4 ¾" deep, same size as the Anchor
Bolts holding down the Lift).
3. Follow the anchoring instructions from the previous procedure to anchor the Power Unit Stand.
See Anchor the Bases for more information.
4. Once the Power Unit Stand is anchored, attach the Power Unit to it using the supplied M8 x 20
Bolts, M10 Washers, and M8 Nuts.
⚠CAUTION The Power Unit is heavy and awkward; we recommend having at least two people
work together to attach the Power Unit to the Power Unit Stand.
5. Use an appropriate tool to securely tighten the connections.

DLR-6/6P Low-Rise Scissor Lifts 18 P/N 5900254 — Rev. A — September 2020
Install the Wheels (DLR-6P only)
The DLR-6P comes with two Wheel Assemblies; they come assembled, but they must be installed on
top of the Wheel Brackets, which are located next to the Hinged Ramps.
Not necessarily to scale. Not all components shown.
To install the two DLR-6P Wheels:
1. Locate the two Wheel Assemblies and the eight Bolts/Split Washers/Nuts.
2. Use a lifting device (such as a jack) to raise the Hinged Ramp end of the Lift up off the ground
approximately 6 in / 152 mm
and hold it up .
3. Put one of the Bolts into place through a Hole in the Wheel Bracket
from underneath .
4. Put a Wheel Assembly into place on top of the Wheel Bracket, then put a Split Washer and Nut
onto the Bolt Threads.
5. Put the other three Bolts/Split Washers/Nuts into place and finger tighten the Nuts.
6. Repeat Steps 3 through 5 for the other Wheel Assembly.
7. Use an appropriate tool to securely tighten all of the Nuts and then lower the Hinged Ramp end of
the Lift back down to the ground.

DLR-6/6P Low-Rise Scissor Lifts 19 P/N 5900254 — Rev. A — September 2020
Hydraulic Fluid Contamination
Hydraulic Fluid contamination poses a serious issue for your Lift; contaminants such as water, dirt, or
other debris can get into the Hydraulic Hoses and Fittings of your Lift, eventually getting into the
Hydraulic Fluid. Once debris is in the system, you could experience issues such as one Platform
lowering faster than the other, internal and external Hydraulic Fluid leaks, slow operation, and so on.
Your Lift is shipped from the factory with clean components; however, we
strongly recommend that
you give the hydraulic components an extra cleaning. Even a small grain of debris introduced into the
Hydraulic System is enough to make the Lift unusable. It is better (and less costly) to take these extra
steps now, so that you do not need to take your Lift out of service later to fix issues that could have
been prevented.
What you need to do
When you get to the procedure describing how to connect the Hydraulic Hose, make sure to take a
survey of the Hydraulic components that come with your Lift
prior to making connections. There are
several ways to clean the Hydraulic Hoses and Fittings:
•Use an air compressor to blow out contaminants. Clean, dry air is preferred. Keep in mind that the
contaminants are going to be coming out the other end, so be prepared for that.
•For Hoses with ends not secured with Fittings, use a projectile cleaning system that shoots
expandable cleaning “pellets” through the Hydraulic Hoses to clean them all the way through.
HydraCheck, Eaton, and Ultra Clean make these types of systems.
•For Hydraulic Hose ends and Fittings that are not too long, soak part of a rag in the same
Hydraulic Fluid you will be putting in the reservoir, then use the rag to clean out the Fittings and the
ends of the Hydraulic Hoses. Do
not use water or other cleaning fluids, as they should never be
mixed with Hydraulic Fluid.
Some additional steps that will help keep your Hydraulic System clean:
•Always use clean equipment. If you use a dirty bucket or funnel to transfer the Hydraulic Fluid
into the Hydraulic Fluid Reservoir, the contaminants will likely be introduced into the Fluid. When
using cleaning rags, use a lint-free rag.
•Proper Storage. Keep the Hydraulic Fluid sealed in its container until ready for use; store the
fluid in a clean, dry, and cool area.
•Cover the Hoses and Fittings. Before installation, do not leave the ends of the Fittings
exposed; the same applies for Hydraulic Hoses. As a general rule, keep the Hydraulic Hoses and
Fittings capped and kept in a clean area until ready for use.
•Filter the new Hydraulic Fluid. Just because it is new does not necessarily mean it is clean.
Use an offline filtration cart or kidney loop system to make sure the Hydraulic Fluid is clean
before
being transferred into the Hydraulic Fluid Reservoir.
•Avoid mixing different types of Hydraulic Fluid. If Hydraulic Fluid needs to be replaced,
make sure to flush the Hydraulic System of the old Hydraulic Fluid before you add the replacement
fluid; do not mix the two together.
•Remove old thread seal tape. Some fittings are shipped with temporary plugs secured with
thread seal tape, so make sure to thoroughly remove the thread seal tape
before attaching an
