1. Safety
1.1 Safety Precautions
Failure to observe and comply with the following
precautions could result in death or serious personal
injury. Property damage could also occur.
• Always wear protective head-wear, ear protectors,
footwear and gloves (at a minimum rigger type
gloves) suitable for safe operation of the tool.
The protective clothing must not interfere with
safe operation of the tool or restrict the ability to
communicate with co-workers.
• Be sure your workplace is safe. Follow the
instructions in your workplace’s standard
operating procedures and be sure to observe all
communicated safety precautions.
• Before placing the device into operation, check that
all components (including protective equipment)
are securely attached. Be sure that all bolts and
other fasteners are properly tightened. Verify that
all moving parts operate smoothly.
• Read and completely understand the safety
precautions and instructions in this manual before
operating the load skates. Always follow all the
safety precautions and instructions, including
those that are contained within the procedures of
this manual
• Do not use the device if you are tired, ill, under the
influence of drugs, alcoholic drinks, or medications
• Even when the device is used properly and all
safety guidelines are followed, understand that
some residual risks may remain.
• Abide by all the safety instructions and precautions
stated in this manual. Act responsively toward
others when using the device.
• Be sure the operator has completed safety induction
training, specific to the work surroundings. The
operator should be thoroughly familiar with the
controls and the proper use of the tool.
• The operator must be of at least the minimum age
required by applicable local regulations, laws and
the facility standard operating procedures.
• Do not overload the equipment. Never attempt to
move a load weighing more than the capacity of
the load skates. Over loading causes equipment
failure and possible personal injury.
• Ensure the skate/load setup is stable before
moving the load.
• While the load is positioned on the skates, no
person is to be on the load and must maintain a
minimum of 5 ft (1.5 m) from the load to avoid injury.
Staying under lifted load is strictly prohibited.
• Keep hands away from load skate wheels to avoid
injury. This especially applies while the load is on
the skates, but also as a general guideline to avoid
risk of injury even when the skates are unloaded
and stationary.
• Verify the floor can successfully support the load
WARNING

capacity and provides a flat, level surface. Failure
to do so can result in damage to the floor, the
skates, or cause the load to tip.
• Do not use the load skates on inclines, uneven floor
surfaces, near floor edge drop offs, over stairs, or
over gaps in the floor exceeding 0.4 in (1.0 cm) in
width.
• Do not use the load skates if the load pad is
damaged or slick with oil. This could result in the
load unintentionally shifting.
• No person is to be present in between the wall and
the load being moved.
• Do not use the load skates if the wheels appear to
be deformed or damaged.
• Do not push the load with the load skate handle.
Failure to observe and comply with the following
precautions could result in minor or moderate
personal injury. Property damage could also occur.
• Do not allow people to ride on the device.
• Only start to move the load after you have ensured
that all persons have moved away from the danger
area and that the load can sit safely and stably on
the transport skate.
• When placing or moving a load from the skates, do
so in a slow controlled manner.
• Do not load the skates quickly, as this can damage
the skates.
• The loaded skate must never be left unsupervised
and can only remain in the same position for a
short period of time (PU rollers max. 15 min).
• Lowering of the load onto the skate must be
controlled and executed slowly. Excessive lowering
speed poses a safety hazard and can lead to
damage to the device.
• Secure the load to be transported so it does not
roll away or tip over.
• Do not exceed 1.25 mi/h (2.0 Km/h) when moving
the load to ensure a short stopping distance.
• Do not make abrupt changes of direction.
• Verify that the rated capacity of the load skate set
is adequate for the load to be moved. This also
applies to loads with uneven centers of gravity.
Some applications may require front and rear
skates of different capacities. This calculations
must be done prior to moving the load by the lead
person responsible.
• When moving load, verify there is vertical clearance
between both fixed and movable objects. It is best
to block off areas where unintended contact could
occur to avoid possible damage to the load or the
facility in which the load is being moved.
Failure to observe and comply with the following
precautions could result in property damage and/or
void the product warranty.
• Always use Enerpac replacement parts.
• In severe service conditions, be aware that the load
CAUTION
NOTICE
skate must be inspected, cleaned and lubricated
more frequently than normal.
• Monitor the skate and the load during all movements
so that you can react quickly if a problem arises.
• If you must overcome a gradient, use a towing
vehicle with sufficient braking force. Make sure
that the steerable transport skate is not pulled out
from under the load when pulling with the towing
vehicle, or establish a fixed connection with the
load to be transported.
• If the load skate is dropped from a significant
height, have the tool inspected and checked for
proper operation before placing it back into service.
• Always follow the inspection and maintenance
instructions contained in this manual. Perform
maintenance and inspection activities at the
specified time intervals.
• When placing a load onto the skates, evenly
distribute the load.
• When moving the load, do so in a controlled
direction and avoid non-linear travel when possible.
• When moving a load, maintain a minimum
clearance of 1.6 ft (0.5 m) to walls from the load.
• The angle of the handle when pulling the load is
not to exceed 25º from horizontal to the floor.
• Maintain a clean load path free of debris. Verify
that the load will not travel over any speed bumps
or drainage grates.
• When the MSLR skates are used, verify that the
wheels are unlocked so they can freely rotate.
• The operator is responsible for accidents or risks
to other persons.
• Do not overreach. Always maintain proper footing
and balance during use.
• Provide adequate lighting when working with the
device. Keep your work area clean and tidy.
• To avoid any uncertainties during the process, plan
your procedure before starting work.

4.3.3 MLSR Load Skate Description
Enerpac MLSR load skates are an ideal solution for
a wide variety of transporting applications, in which
moving high weight material with high manoeuvrability
is required.
MLSR load skates are high load capacity carts with
different number of nylon wheels depending on the load
capacity required, which ranges from 3 to 9 tons.
WARNING
MLSR skates come standard with nylon wheels.
Polyurethane wheels have a lower capacity than
nylon wheels and should not be used unless
approved by Enerpac.
MLSR models have pivoting wheel boxes which allow
the skate to rotate 360º with minimal linear travel. The
slot situated on the front of the skate allows connecting
bars or handles to be installed.

5. Operation
5.1 Placing load on skates (Figure 9)
Do not use skates if the wheels appear to be dam-
aged or deformed.
To position the load onto the skates, lift one end of the
load to allow the load skate to move underneath the
load.
Once the load is lifted, MLSD or MLSR trailing skates
must be positioned at 90 degrees from (or perpendicular
to) the center axis of the load. The load can now be
lowered slowly to rest on the rear skates.
Repeat this operation to position the front skate (MLSF
or MLSR) under a suitable location on the opposite end
of the load. If necessary, block the rear skate wheels so
the load is not able to move.
If enough lifting devices or a crane or forklift are
available, the load can be lifted evenly and set on all
skates simultaneously.
While the load is positioned on the skates, no per-
son is to be on the load and must mantain a min-
imum of 5 ft (1.5 m) from the load to avoid injury
Before disconnecting the lifting device and trying to
move the skates, verify that the front skate (MLSF or
MLSR) is located along the center axis of the load.
When placing or removing load from the skates,
do so in a slow, controlled manner
Verify that the rated capacity of the load skate
set is adequate for the load to be moved. This
also applies to loads with uneven centers of grav-
ity. Some applications may require front and rear
skates of different capacities. These calculations
must be done prior to moving the load by the lead
person responsible.
Ensure that the load is distributed equally between the
two skates to avoid any potential overloading.
Figure 8: Distribution of the load
CAUTION
WARNING
CAUTION
CAUTION
NOTICE

12 L4535_b
Keep hands away from the load skate wheels
to avoid injury. This especially applies while the
load is on the skates, but also as a general re-
quirement to avoid risk of injury even when the
skates are unloaded and stationary.
Do not use the load skates if the load pad is dam-
aged or slick with oil. This could result in the load
unintentionally shifting.
5.2 Moving the load
When moving a load there has to be a vertical clearance
between the load and fixed objects. Properly secure any
movable object in the load to avoid possible damage to
the facility where the load is moved.
Use the proper handle depending on the skate that is
being used and the load that is been moved.
Verify the floor supporting the load is able to do
so and provides a flat and level surface. Failure
to do so could result in damage to the floor, the
skates, or cause the load to tip.
Do not use the load skates on inclines, uneven
floor surfaces, near floor edge drop offs, over
stairs, or over gaps in the floor excceding 0.4 in
(1.0 cm).
Move the load slowly and carefully, maintain a minimum
distance of 1.6 ft (0.5 m) to walls from the load. The
angle of the handle when pulling the load is not to
exceed 25º from horizontal to the floor.
When moving the load do so in a controlled direction
and try to avoid non - linear travel when possible.
Figure 11: Safety measures when moving the load
If using MSLR load skates, verify that the rotating skates
are unlocked before begin to move the load. Also verify
that the rotational load pad functions correctly.
When moving a load over a step, approach the step
with the steering skate. Once at the step verify there is
enough of the load overhanging the step to then allow
