Gap between load nut and safety nut when new should be 25-31mm. Maximum allowable wear of load nut thread is 1.5mm. Safety cable should be adjusted so that the arms on the limit switch plate at the top of the power column are both horizontal when the lift carriages are not at either end of their...
The guide rollers on the power column are a much lower profile than the auxiliary column guide rollers.
In the past, I have put spacers under the cable anchors at the top of the columns to compensate for uneven floor, but never anything like 150-300mm. If I were you, I would replace the lifting...
I’ve not got a manual for them, but the installation is very similar to other Bradbury 4 post lifts.
Build up the platform superstructure c/w cables and pulleys, position it where you want it to be. Locate the power column square to the base, fasten down the power column (ensure it is plumb in...
It’s a Bradbury 735.
735 (Liftmaster mk1) has floor mounted tank, horizontal triple pulley box and control via single handle at top of power column
799/800 (Liftmaster mk2) has floor mounted tank, vertical triple pulley box, raise via contactor button half way up power column and lower via top...
Erratic readings on gas analysers are usually the result of water contamination of the infrared gas bench.
I would be looking there first before delving into the electronics. I‘m not familiar with this particular model, but in most cases it is possible to remove, strip down the bench and clean...
Bradbury used to offer a waterproofing kit for lifts used outdoors/steam cleaning. Whilst it helped, it still allowed ingress of water. The life time of hydraulic oil/pumps/seals and electrical components was still drastically reduced. The rest of the lift structure would also suffer prematurely...
@mm289 from memory (and it’s a long time since I had one of these in bits!) I’m 99% sure that the square section tube should be connected to a piece of flexible tube inside the power column shroud and facilitates the return to the hydraulic tank of any oil which has gone past the ram seal.
These mk2’s are always awkward to get the power column apart, but it sounds like you’ve worked it out. The later 40 series are much easier!
You‘re right about the oil feed from the motor to the ram, it is a machining in the base plate and the tank/motor/pump assembly does not separate from the...
Lift up the outer shroud of the power column to expose the 4 bolts which fasten the lifting links to the platform end beam. In order to lift the column shroud, you first need to disconnect the lowering valve lever mechanism (small access hole in shroud, just below the level of the top of the...
That’s not a 40 series......
That’s an 800 mk3
Check the RED painted bolt on the LHS of the valve block inside the cabinet is tight. That is the emergency release in case of power cut. This is needed because 800 mk3 has a solenoid valve integral to the valve block which 40 series doesn’t.

It sounds like something is initially sticking inside the pressure switch. For the price of them (less than £15 on Amazon) compared to the irritation factor of it not working properly, I would just replace the pressure switch.
For peace of mind, I would also replace the safety valve if it has...
Some of the older Clarke compressors had a safety valve fitted on the discharge pipe between the head and the receiver.
