Operating instructions

(5) Clean the tubes with a cloth and examine the tube surfaces. If there are dents or

sufficient surface damage to affect the seals, then the section will not function

correctly and should be replaced.

(6) Remove the faulty seal; in most cases the damage is imperceptible. Having oiled

or greased the new seal, fit into the piston groove using only the fingers, DO NOT

USE METAL TOOLS. The PTFE slide ring “E” should be replaced at this stage if

necessary (see separate instructions at 6a over page).

(7) The sections must now be refitted with great care. It is possible to damage the

new seal on the edge of the receiving tube. Check the edge for sharpness or

burrs also check the screw holes and ensure they are completely smooth. Then

oil or grease it to help insertion of the section with the new seal.

(8) Line up the section to be inserted, with the new seal at a slight angle to the mouth

of the receiving tube. Hold the edge of the seal down with the thumb and turning

the tube, allow the compressed part of the seal to enter the receiving tube. Once

all the seal is inserted, correct the angle so that the tubes line up and insert

Teflon slide ring. Keep the tube being fitted as concentric as possible with the

receiving tube, until the stainless steel tube stop “C” has just entered. The collar

can now be pushed forward onto the receiving tube and when secured it will

maintain radial clearance.

NY SERIES

The NY mast has additional anti-rotation locking pins engaging in slot in the stainless

steel stop sleeve.

The mast should be assembled in the normal way but with these pins removed.

Replace them as each section is built up.

(1) Pull out section to its maximum i.e. until the stop sleeve comes against the

support collar.

(2) With a pencil, mark the section at the collar.

(3) Push in section about 25mm. Screw in locking pin until it touches the bottom of

the keyway then unscrew half a turn.

(4) Pull out section. If the pin is engaging the slot the section will come out enough to

enable the pencil mark to be seen again i.e. the stop sleeve will be against the

collar.

(5) If the pin does not engage push in the section again, continue to unscrew the

locking pin and repeat instruction 4. The pin should only be unscrewed a few

degrees at a time each successive attempt

(6) Finally, screw lock nut down firmly.
