5. Slowly lower the cylinder rod until the weight of the load
is supported by the U-Rings. Refer to the information in
Section 5.3 for jack operating instructions.
IMPORTANT: Follow all applicable work rules and regulations
in effect at your facility or worksite. The use of auxiliary stands,
blocking or other additional load supports may be required even
when U-Rings are installed.

6.0 MAINTENANCE

6.1 Maintain Oil Level in Hydraulic Reservoir
Check the hydraulic oil level every 30 days. Oil level should be
approximately 1 inch [25 mm] below top of reservoir, with cylinder
fully retracted and motor off.
If oil level is low, add Simplex hydraulic oil as required. If Simplex
hydraulic oil is not available at the work site, use an equivalent
hydraulic oil that meets the specifications shown in Table 8.

CAUTION: Failure to use the proper oil may result in
damage to jack hydraulic components and will void the
product warranty. Use of Simplex hydraulic oil is
strongly recommended.
IMPORTANT: Be sure that the oil is clean. If the oil has a milky,
cloudy or dark appearance, it should be changed immediately as
described in Section 6.2.
6.2 Changing the Oil (See Figure 6)
Change the oil at least every 12 months.
Note: The following conditions will require more frequent oil
changes:
• Rigorous duty, where oil temperature may reach 150 °F
[60 °C].
• A high humidity environment and/or extreme changes in
temperature that can result in condensation inside the
reservoir.
• Dirty or dusty environments that may contaminate the oil.
