Operation.
3.2.1. To fit a Skate to a wheel you must first turn the release valve anticlockwise (fig.2) and
remove the locking pin (fig.3).
3.3.
Positioning the Skate.
3.3.1. Take hold of each side of the frame and expand the unit until it is wide enough to slide
the rollers either side of the tyre. Make sure that both sets of rollers are centred on the
tyre.
3.4.
Raising a wheel.
3.4.1. Now close the release valve by turning clockwise (fig.2).
3.4.2. Operate the foot pedal lever to commence raising the wheel. (IMPORTANT - Allow the
pedal to return through its full travel before commencing the next stroke.)
Continue until the tyre is clear of the ground and you are able to insert the locking pin
as shown in fig.3.
3.4.3. Raise the second wheel off the ground with the other Skate. Be prepared for any movement
the vehicle may make when the second wheel comes clear of the ground. This is
particularly important when using four skates. Providing the ground/floor is level the vehicle
should remain stable. (Read safety precautions in Section 1.)
3.5.
Moving the Vehicle.
3.5.1. Ensure that you have sufficient manpower to move and control the vehicle. Keep well
away from any sloping areas or entry ramps to the area, however shallow they may
appear. When positioning a vehicle in relation to a wall or feature such as a pillar no
persons or objects should be situated between the vehicle and the feature. Sufficient
space should be left between the side of a vehicle and an adjacent wall or feature to
allow the Skates to be withdrawn sideways.
3.6.
Lowering wheels.
3.6.1. Remove the locking pin and turn the release valve anticlockwise to lower the vehicle
until the tyre is on the ground and no longer exerting pressure on the rollers.
3.7.
Removing the Skate.
3.7.1. Expand the unit sufficiently to clear the tyre and move it away from the wheel.
IMPORTANT: BEFORE THE FIRST USE OF SKATE PURGE AIR FROM THE
Before using the skate for the first time, purge the hydraulic circuit in order to eliminate
any air, that may have accumulated in the system during transit, as follows:
1.
Open the release valve by turning knob anticlockwise.
2.
Pump the pedal up and down 15 to 20 times.
3.
Turn the release valve clockwise to close the valve.
4.
MAINTENANCE
4.1.
Periodically lubricate the wheels, rollers and the foot pedal lever pivot with acid free oil.
Lightly grease the four faces of the square section tube.
4.2.
When the skate is not in use, store fully closed with the locking pin in place, this will
minimise ram and piston corrosion.
4.3.
Keep the skate clean. Lubricate all moving parts with acid free oil.
4.4.
Before each use, ensure components are in good working order. If any suspect item is
found remove skate from service and take necessary action to remedy the problem.
DO NOT use the skate if you believe it has been subjected to an abnormal load or shock load. If in doubt contact your local service agent.
IMPORTANT: All other maintenance and repair (including oil change) must only be undertaken by fully qualified personnel. Contact your local
authorised service agent.
4.5.
The oil cylinder is a sealed unit and in principle should not be accessed. To top up the oil remove oil plug (fig.2). The oil level should
be just below the oil plug hole.
WARNING! Only a good quality hydraulic Jack oil, such as SEALEY HYDRAULIC JACK OIL must be used, DO NOT use brake fluid.
!
DO NOT overfill as this will render the skate inoperative.
IMPORTANT: NO RESPONSIBILITY IS ACCEPTED FOR INCORRECT USE OF THE SKATE. Hydraulic products are only repaired by local
service agents. We have service/repair agents in all parts of the UK. DO NOT RETURN SKATES TO US. Please telephone 01284 757500 to

De-commissioning the skate: If the skate becomes completely unserviceable and requires disposal, draw off the oil into an approved
container and dispose of the skate and the oil according to local regulations.
