GATE CATCH
The gate catch is a steel spring clip that can be released by pushing on the tab indicated by the arrow. To close the
gate simply pull the gate and ensure the catch springs over the side guardrail vertical tube gripping it fully.
SIDE GUARDRAIL LOCKING DEVICE
The side guardrail locking device is a gravity operated locking collar used to lock the side guardrail folding hinge in
the upright position. Simply allow the collar to drop over the hinge when assembling the unit and slide the collar
up to release the hinge when disassembling the unit.
SIDE GUARDRAIL BRACKETS
The side guardrail brackets allow the side guardrails to fold and serve as a locking device for the lower portion of
the side guardrail. The wide slotted bracket is the side highlighted in green and the narrow slotted bracket
highlighted in red. On assembly the green bracket is opened last and on disassembly closed first. The side guardrail
must be lifted and rotated simultaneously as shown, during both assembly and disassembly.
TRANSPORT STRAP
The transport strap holds the folded side guardrail assemblies in place for when the unit is being transported or
stored. Pull the elasticated transport strap unitl the metal hook is clear of the guardrail and then either let it drop
over the guardrail for transportation or remove the hook from the guardrail and release the tension if assembling
the unit.

foot, to lock or release the brake.
ADJUSTABLE LEG
The adjustable leg allows further height changes to be made can be extended or retracted by simply pushing in
the spring locating pin (A) and either extending or retracting the adjustable leg (B) until the spring pin locates into
one of three locating holes in the outer leg assembly (C).
LEG ADJUSTMENT LEVER
The lever (highlighted in green) allows rotation of the leg assembly (A) and once locked off in either of the
positions (1,2 or 3) it provides height changes to the unit. Release the leg adjustment lever using the handle (B)
and rotate the leg assembly (A) either way until the lever engages in either position 1,2 or 3.

LEG ASSEMBLY
The leg assembly holds the adjustable legs in place and also adjusts the height of the unit by using the leg
adjustment levers. When not in use the leg assembly is packed under the platform and held in this position by the
leg retaining clips.

The leg retaining clip is a spring clip that simply grips the lower rung of the leg assembly and holds this leg
assembly in place during storage or transport. To release the leg assembly, simply pull it until the assembly is
released from the clip or push the leg assembly against the clip, until it grips the lower rung, to put the leg
assembly in the transport position.
