INTRODUCTION
The Sertes 75 llydraullc Cuttlng Press ls a fast stroklng, 2 pillar
press whlch ls hydraullcally operated and electrlcally controlled.
The press base ls a folded steel fabrlcatlon whlch supports the bed
fabrlcatlon and lncorporates the hydraullc oll t,ank.
The cutting power ls provlded by two cyllnders whlch are lntegral wlth
the head gulde ptllars whlch sI1de ln bearlngs through the bed. Ttre
flxed piston rods are elanped in a crosg head whlch is bolted Eo the
bed fabricatlon lrlth the press head connected to the tops of the
plllars by trunnlon pl.ns and eccentrlc bushes.
The hydraullc oll pressure ls provlded by a punp drlven by a 5.5 kw
(7.5 HP) electrlc motor coupled to a flywheel. lThe notor prnp unlt ls
uounted directly on t,op of the o1l tank underneaih the bed of thA
Pregs. t
An autooatlc balanclng neehanism enaures that the head renains
parallel to the bed throughout the cutting atrd return strokea, the
upper and lower llntt posltlons being monltored by a lLnear
potentlometer connected across the balancLng valve.
The head llnlt positlons are set by two rotary potentl.ometers on the
control box.
The electrlc control box ls nounted on the rtght hand side guard and
Lncorporates all the controls whlch are connected to the press by
flexlble conduits whlch ternlnate ln two nultlpln plugs and sockets
below the control box.
rn its standaid foru the press ls fltted w'tth a manual work tray which
carrles a cutting natrix. The tray runs on spring loaded rollers
which hold tt clear of the bed untll the cuttlng pressqre is appLled.
Ttre Serles 75 press can also be fltted wlth a range of nanual and
seml-autonatic work feed systeus whlch greatLy increase lts range of
oPeratlon.

Liftlng the Press
Before llfting, all.work handllng devices 1.e. work trays, table
arms and assoclated parts nust be removed fron Ehe press. In
addltlon, the tray support roller assemblies, where fltted' nust
be removed fron the bed of the uachlne. The nachlne can then be
lifted by passlng spreader bars. through the holes provided ln Lhe
head and sllnglng as illustrated, see flg. 1. The press nay also
be llfted by a fork llft truck lrlth the ltftlng arns positloned
under the head of the press. Before ltfting this way, the head
must be powered to lcs uppernosc posltlon and wedged in placed

Flnal position caa be achleved usLng a crow-bar under the base
and adjacent to che press feet.
Skates nay be used to t,ransport the nachlne only lf used under
the feet of che press. To positlon skat,es, llft as descrlbed
above or by uslng "Toe-Jacks" under the oachlne bed after
first removlng the oachlne covera.
Checklng for Level
#Install the press on a level reinforced concrete floor capable
of wlthstandlng the dynanlc load of the press. Uslng an
rengineersr levelr placed on the bed of the press, level the
pr6ss by lnserting antl-vlbratlon pads and/or metal shLms on
hardboard between the press feet and the floor. Check that the
level of the hydraullc ol1 ls visible ln the sight glass of the
integral tank. llachlnes for export are despatched dry and
require 117 Lltres (26 gallons U.K.) of hydraullc o11 (SHEIL
