• 2.5" cylinder bore

⭐ Screw-Drive Manual Override for Power Loss

• Take care not to contact wires or hoses with the drill

What's Included (8107UPS)

• One AM-series 24" stroke jack
• Commercial single-function pump with screw-drive manual override
• Pump cover
• Keyed rocker switch and harness
• Universal mounting brackets
• Wire harnesses in PVC high-temperature nylon braid for tough environments

What's Not Included

Ships without fluid (uses Dexron III ATF) and without mounting bolts (bolt kits available separately).

Battery Requirements

Load-test the battery before installing. EQ Systems requires a minimum of 150 amperes at 10.5 VDC for at least 30 seconds. Keep terminals tight and free of corrosion.

Fluid and Maintenance

Runs on Dexron III ATF, filled to about 1" below top of reservoir with jack fully retracted (level rises as jack retracts). Reservoir must run with its vented breather cap fitted, not the flush shipping plug, or the jack will operate erratically. Inspect every 12 months: check connections tight and corrosion-free, particularly the ground to the pump stud and positive cable to the motor solenoid.
