4. Remove fi lter bowl and inspect the air fi lter element (inside
fi lter bowl). Replace fi lter element if dirty.

Norgren for detailed maintenance instructions, fi lter elements
and replacement parts.
7.6 Air Line Lubricator (See Figure 13)
Every 30 hours of operation:
1. Remove the jack rear access cover. Refer to Section 7.1.
2. Check the sight gauge on the air line lubricant bowl. The
lubricant level should be at least 1/2 full.
NOTICE If lubricant level is low, add additional lubricant as
described in steps 3 through 6. If lubricant level is OK, skip these
steps and go to step 7.
3. Completely relieve any trapped pressure in the jack hydraulic
and pneumatic systems. Disconnect the air supply hose
from the air shut-off valve. Follow procedure in Section 7.2.
WARNING Be certain that jack pneumatic system is
completely depressurized and regulator air pressure gauge
indicates zero (0) psi/bar before removing lubricator fi ll plug.
Lubricant may spray from fi ll opening if fi ll plug is removed
while system is pressurized, even when air hose has been
disconnected and air shut-off valve is in the closed position.
Serious eye injury and/or skin penetration could result.
4. Remove the lubricator fi ll plug. Add additional lubricant as
required, until the level reaches the top of the lubricant bowl
sight gauge. DO NOT OVERFILL!
For ambient temperatures above 32°F [0°C], use a high quality
SAE 10 [ISO 32] air tool lubricant. For ambient temperatures
below 32°F [0°C], use only a glycol-based anti-freeze air tool
lubricant (Enerpac part number DD5142835 or equivalent).
NOTICE Lubricant level must not be higher then top of site
gauge. Do not operate jack with excess lubricant in lubricant
bowl. If lubricant bowl is overfi lled, jack air logic circuit may
become fl ooded with lubricant, preventing normal operation
of jack.
5. Reinstall the lubricator fi ll plug.
6. Reconnect the air supply hose. Be sure the air shut-off valve
is in the OPEN position.
7. Check the lubricator drip speed in the drip window:
• Drip speed should be 4 to 5 drops per minute. Always check
the drip speed while the cylinder is advancing or retracting.
• If drip speed is too slow or too fast, readjust the drip speed
as required. Use a fl at blade screwdriver to turn the drip
speed adjustment screw.

8. Reinstall the jack rear access cover. Refer to Section 7.1.
7.7 Air Muffl er (See Figure 14)
Every 30 hours of operation:
1. Remove the jack rear access cover. Refer to Section 7.1.
2. Disconnect the air supply hose from the air shut-off valve.
Completely relieve any trapped air in the jack pneumatic
system. Follow procedure in Section 7.2.
3. Inspect the air muffl er. Remove any loose dirt or debris.
4. If old air muffl er is very dirty or clogged, replace it with a new
air muffl er. Use only a 25 micron air muffl er of the original
specifi cations (Enerpac Part No. DD4791116 or equivalent).

7.8 Wheels and Tires (See Figure 15)
Every 30 hours of operation:
• Check the tires for wear or damage. Replace as required.
• Check the tire infl ation pressure. Each tire should be infl ated
to 90 psi [6,2 bar].
Every 12 months:
• Each wheel hub contains a grease fi tting. Lubricate both wheel
bearings with a high quality wheel bearing grease.
• Inspect the caster wheel for damage and check that it turns
and pivots freely. Remove any loose dirt and lubricate bearings
with oil. Refer to Figure 7 in Section 5.7 of this manual.
