11 MAINTENANCE
Depending on the working conditions and the use of the tool the following maintenance has to be made
periodically:
11.1 Air-unit
• Checking the air pressure daily.
• Checking the oil-level daily.
• The water separator must be emptied before it is full (unless automatic).
• The filter has to be cleaned following the instructions of the manufacturer of the air- unit.
• Check the function and proper adjustment of the lubricator daily (approximately 1-2 drops/min.)
Oil for the air-unit
HL or CL ISO-VG 10
11.2 Oil level in the pressure intensifier
Control
A proper operation of the tool is only warranted if there is the correct amount of oil in the pressure intensifier.
The position of the piston in its idle position reveals whether there is enough, too much or not enough oil in the
pressure intensifier. A flawless operation of the tool is guaranteed only if the amount of oil in the pressure
intensifier is correct!
If there is too much oil in the pressure intensifier the position of the piston in its idle position is lower than the
lower edge of the body (visible when flapper is open). As a result of this faulty position of the piston there is
not enough space for the straps and the seal joint resp; it is difficult or impossible to insert the straps into the
tool and to remove them from the tool resp..
If there is not enough oil in the pressure intensifier the position of the piston in its idle position is higher than
the lower edge of the body (visible when the flapper is open). As a result of this faulty position of the piston
there is a risk that the stroke of the piston during the sealing action is too short and consequently the seal joint
is not formed properly and the upper strap is not cut entirely in spite of the correct adjustment of the adjusting
screw resp..
Oil for the pressure intensifier in the tool
SAE 10W-20 (for refilling)
Refilling of oil into the pressure intensifier
• Turn tool with flapper in an upward position. Remove sealing screw.
• Introduce wrench (N7.3250) into boring with valve handle being parallel to the toggle, turn toggle by 90
°
(thus the sealing piston is moved into its correct position).
• Turn back the wrench and remove it.
• Fill in oil of type SAE 10W-20 and let escape air bubbles. Screw in sealing screw again and tighten it.
• Check the position of the sealing piston as per afore mentioned instructions.
