Place the piston seal in hot (not boiling) water until pliable, and
fit to piston with the outer lip facing outward, and ensure that
the seal is fully home in the groove. Push piston back into bore
using hand pressure only. Repeat the procedure with the second
piston.
3 Do not push the piston in to the bore too far, the seal must not
travel as far as the cut-away inside the body. Move the pistons
in the bores until the hole in the centre part of the link (part No.
1150) lines up with the centre shaft hole in the body, and fit
centre shaft (part No. 9511)
4 Fit roll pins (part no. 9514) and screws (part no. 5056) in to the
two threaded holes in the front , to secure the centre shaft.
5 Should the blade grip block, or its screws require replacement at
any time, this can be achieved without removing the pistons
fully, which would damage the seals. With the handle/valve
block removed, pushing the piston as far forward as it will go,
will reveal the retaining pin. Tap this out, and replace blade grip
block. Use a new retaining pin each time.
