MAINTENANCE

ADDITION OF HYDRAULIC FLUID (Use Mobil DTE 24)

To purge all the oil from the tool, Hook tool to air supply and remove oil fill plug (I) and lay flat

on a work bench. Place tool in a bag and cycle tool 5 or 6 times which will purge all the

remaining oil from the tool. Screw oil container and cycle tool until oil fills the tool and no air

bubbles remain.

Note: If tool stroke seems to not be adequate, add oil

The Hydraulic oil should be topped off after a long period of usage or when there is a power loss
of the tool. Put the tool in a vertical position rotating the knob (M) towards the plus sign + up to
the end of the stroke, and remove plug (I) by using a 4mm Allen wrench (supplied). After
removal of plug (I), check the oil level in order to avoid overflowing. Next screw the oil
container (S) supplied into the oil inlet hole until it is seated. While keeping the tool in the
vertical position connect the air line and push button (D) and then cycle the tool several times
until air bubbles in the oil container (S) stop appearing in the oil container (S). This indicates that
tool is filled of oil and is ready for use. Disconnect the air line and unscrew the oil container (S)
from tool and replace plug (I) first checking to be sure the washer on plug is in position and not
damaged.

IMPORTANT: Make sure plug (I) is
tightened at a torque corresponding to
min. of 3.6 ft-lb and a max. of 5.9 ft-lb
