Safety
Toggle
Fastening holes Fastening holes
5. Locate the control unit in an appropriate position away from the hoist. A qualified electrician must wire the control unit.
Refer to Electrical diagram Page 15. Fill tank through breather vent with the supplied Hydraulic oil.
6. Dry filtered compressed air at 6 to 7 bar line pressure is required to operate the safety mechanism. The control unit is
supplied via an inline particulate filter which requires a ¼”BSP threaded fitting from a min 6mm ID supply line.
7. Attach the hydraulic hose from the control unit to the hoist. The connection is under the Left (passenger side) wheel
run up ramp. Insure all hydraulic fittings are tight and not leaking, refer to page 15 Betabite Hydraulics Assembly
Instructions. Optional connection can be made under Right wheel run up ramp by relocating the pipework end plug
fitting.
8. Connect electrical limit switch wires and pneumatic airline to connection points at front left hand of hoist. Secure with
The Hydraulic line and U shape cover. Optional connections can be made under Right wheel run up ramp.
9. The hydraulic hose, electrical wires and pneumatic airline must be protected from accidental damage. Use 6mm (1/4”)
wall plugs to secure supplied covers to the ground. Extra covers are available, please contact your local supplier.
10. Raise the hoist and inspect hoist for correct operation and that the safety toggles are locking.
11. Install the run up/run off ramps and centre cover onto the hoist. Swap pickup extension so handles are on the
outside of the scissor lift.
12. NOTE: For efficient operation of your hoist please adhere to the maintenance schedule

Assembly Instructions
1. Cut the tube to length and file ends square.
2. Remove internal and external burrs from tube end.
3. We always highly recommend that joints are pre-made whilst the coupling body is
held firmly in a bench vice.
4. Ascertain that all the detail parts of the coupling are suitably lubricated, especially
the internal body cone, the rear of the ferrule and the internal thread of the nut.
The lubrication process is recommended on all fittings, however, on stainless steel
couplings the use of a quality lubricant is imperative. Betalube, a copper based
paste is highly recommended and available from Betabite Hydraulics or your local
distributor. Please note after assembly, fittings to be used on Oxygen lines should be fully
degreased.
5. Slide the nut onto the tube, followed by the ferrule, the open end of the nut should
be towards the end of the tube, and similarly, the cutting or smaller end of the ferrule
should point towards the tube end.
6. Present the tube, nut and ferrule to the coupling body, making sure that tube passes
cleanly through the nut and ferrule & butts firmly against the step (abutment face)
provided in the coupling body. Screw the nut onto the coupling body until finger tight.
7. Hold the tube in one hand and with the correct sized spanner in the other hand,
tighten the nut until the ferrule is felt to just grip the tube. This point is determined by
rotation or slightly rocking the tube. From this point, the nut should be tightened 1 ¼
to 1 ½ turns from the initial ring grip to obtain a fully effective cutting action.
On larger sizes of fitting, an extension to the spanner is highly recommended to
maximise leverage and minimise effort.
8. If the nut is now removed, the ferrule will have cut its own seating on the tube and
whilst it will be found to rotate, it cannot be moved towards the tube end. The ‘joint’
may now be re-assembled, by re-tightening of the nut until significant resistance is
felt and then increase for a further ⅛ to ¼ of a turn. The above procedure must be
followed closely to ensure a safe and successful joint.
9. Betabite fittings correctly made can be broken repeatedly, when not under pressure
and re-made without affecting their pressure tightness and leak-proof quality
