Oilfill and removal of air pockets
Packings and sealings are of highest quality but a small oil loss can occur after some use and a small replacement
quantity of oil will have to be added. (The total oil volume is about 0.10 litre).
Before oil fill, the tool must be carefully cleaned on the outside. It is very important that even very small dirt particles
must never enter into the hydraulic system.
NOTE!
The key grip, 32 mm, MUST NEVER be used when loosening the fixed handle.
The refilled oil must be unused and clean.
While the tool is still in vertical position (i.e. with the handles upwards) the oil level should reach the upper edge of
the filling hole. Then pump, with press dies assembled, until full pressure is reached and let the piston return to rest
position. Repeat this until the tool is completely free from air pockets.
Thereafter, pump out the press piston carefully 2-3 mm from resting position and fill oil until oil surface reaches
the edge of the oil hole. Replace and fasten the screw. Check the rubber sealing under the screw head to
ensure tightness. Wipe off excess oil on the outside and reassemble the handle. The tool is now ready for use
(=functional check).
With empty press dies, the piston fast feed shall be effected in about 5 full handle strokes and thereafter about 6
handle strokes more are needed to achieve full pressure.

Service
If the tool is not operating satisfactory in spite of proper handling, proper oil fill and removal of air pockets, it must be
returned to factory or authorized service shop for further actions.
IMPORTANT!
No other servicing than the above mentioned can be made without authorization on the
pump system. The design of the pump unit is complicated and special tooling is needed
for disassembly and assembly of the unit.
Hold the tool in a screw
vice with the handles
upwards and press dies
assembled in the head.
The fixed handle is
removed by screwing,
aided by a pipe wrench
or similar, the grip can
be increased if a strip
of emery cloth is placed
between the steel tube
and the wrench jaws.
Remove the screw at
the oil container’s
(rubber hose) top end.
Refill with oil type
Shell Tellus Arctica 32
or Aeroshell Fluid 4.
