p
workshop practice regulations are strictly adhered to when using tools.
DO NOT use ram or associated tools if damaged or worn.
7
Maintain the ram and associated tools in good and clean condition
3
for best and safest performance.
Check the specification of the puller tool you will be using to ensure
3
that it is rated to match the force that the ram can apply.
Ensure all threads are clean and well lubricated.
3
Always check that the ram is correctly assembled into the puller
3
being used and is square with the workpiece.
If working on a raised vehicle, ensure that it is adequately supported
3
with axle stands, ramps, etc. as appropriate.
Wear suitable clothing to avoid snagging. Do not wear jewellery.
3
Tie back long hair.
Wear approved eye protection. A full range of personal safety
3
equipment is available from your Sealey dealer.
Where possible shield workpiece with canvas or similar to provide
3
protection against failed parts.
DO NOT use any tool or lever to turn the ram tommy bar, use
7
hand effort only.
DO NOT hit workpiece, or ram, with a hammer if workpiece has not
7
moved with maximum puller force applied. Use a larger capacity puller.
Account for all tools and parts being used and do not leave them in
3
or on the vehicle.

p
p

INSTRUCTIONS FOR:
HYDRAULIC RAM UNIT
PS990
MODEL NO:
4.2 Check that the specification of the puller tool you will be using is
compatible with the ram unit.
4.1. Confirm that the workpiece is retained by interference fit (parallel
or taper) only.
4.2. Assemble the ram into the chosen puller, (see typical pullers as
shown in fig.1), and adjust
T-handle (Fig. 2.A) so that tommy
bar (fig.2.B) is approximately
80mm (3”) above top of ram, see
fig.2.
4.3. Fit the puller to an appropriate
position behind workpiece and then
screw the ram body down until it
makes contact with the end of the shaft from which the workpiece is
to be pulled. (If the shaft has a centre position machined into its
end surface use a matching centre adaptor to locate centrally with the
shaft.
4.4. Turn T-handle clockwise, by hand only, to pull workpiece from shaft.
4.5. Do not screw T-handle in further than 25mm (1”) from end of the
ram (see fig.2). If workpiece requires additional movement
then unscrew T-handle to 80mm from end of ram, screw ram
body down so that centre adaptor again contacts shaft and
then continue to draw workpiece up shaft.
IMPORTANT: The maximum safe load for the puller can be achieved by
hand effort alone. The use of tools or levers on the tommy bar to
increase the load will damage the puller and may result in injury.
Such misuse will also invalidate the warranty.
If the workpiece does not move, with maximum puller force applied, DO
NOT hit it, or the puller, in an attempt to jar it free. Damage to
puller/workpiece and personal injury may result. Use a larger capacity
puller.
