7. Lubricate all seals.
8. Mount new cartridge. For ease of mounting, hold the cartridge away from the
magnetic core until the stud is through the hole in the bottom of the element. Then
slide it up to securely seat with the top of bridge.
9. Install bypass spring assembly.
10. Re-install insert into filter housing (make sure the top spring is secure).
11. Re-install cover. Torque cover nuts to 35 ft/lbs.
12. Check for and eliminate leaks upon system start-up.
13. Check differential pressure indicator to monitor element condition.
d. Tank Cleaning : The tank should be drained and cleaned approximately every 1000
hours of operation. Be sure to clean and remove any particles in the bottom of the
reservoir. Use lint free rags. Use a filter when re-filling with a mesh width of 0.002"
(0.06MM) or better - fill via 10 micron system filter.
CAUTION : Serious damage will result from excessive hydraulic pressures. High
pressure will not speed cycle times. Alterations in relief valve settings will void all
warranties.
Pneumatic Filters & Lubricators
The filter and lubricator are a part of the SMC Filter-Regulator-Lubricator Combos
that are mounted on the Weld Splice Station and the Pull Thru Welder. This is where
the air lines are connected to the fabricator.
a.
Filter Element : Filter elements should be changed after 1 year or when a pressure
drop of 15 PSI (1kgf per square cm) is reached. The safety lockout valves must be
locked in the "OFF" position and pressure removed from system before attempting
to change filters.
b.
Lubricators : The Lubricators should be checked daily and refilled as needed.
SMC recommended oil is ISO VG32. A section of the reservoir bowl is
transparent to allow maintenance personnel to view the level of the oil. The
reservoir should be checked approximately once every eight (8) hours and refilled
as needed. To refill, maintenance personnel must:
1> The air pressure must be padlocked in the OFF position.
2> Press the release button indicated by an arrow on the front of the device and
rotate the reservoir bowl 1/4 turn counter clockwise.
3> Remove the bowl and refill with ISO VG32 (or equal) oil. A fill level line is
marked on the side of the bowl to indicate the proper fill level.
4> Secure the reservoir bowl back in place and turn the air back to the ON position
to resume operation.
