Literature & Documentation
Specifications (from the KTI catalog)
| Usable volume (horizontal) | 3 QT |
| Tank length “A” | 8.00" |
| Material | Polyethylene (plastic square series) |
Fill to ~1" from the top with the unit at rest; the reservoir should sit about ½ full with the cylinder fully extended. Never let it drop below ½ while running.
Hydraulic fluid
KTI fluid recommendation: premium hydraulic oil with anti-wear, rust/oxidation and foam inhibitors — e.g. Chevron Rando HDZ, Mobil DTE 10/20 series, AMSOIL, Shell Tellus. Automotive ATF is acceptable under normal conditions. Do not use biodegradable hydraulic fluid, and do not mix oils.
| Ambient temperature | ISO viscosity grade |
|---|---|
| −20 °F to +32 °F | ISO 15 |
| +14 °F to +120 °F | ISO 22, 32, or ATF |
Purging air after install
Bleed cycle (purge air) in 3 steps:
- Remove the breather cap so you can watch the fluid level. Verify fluid connections are tight. Never let the level fall below half while running.
- Run the unit to extend the cylinder, keeping the level above half tank.
- At full extension, run 5–10 seconds more (bleeding over the relief valve), re-check level, retract, and repeat until operation is smooth.
Double-acting units: repeat for both power-up and power-down. If fluid foams, wait ~10 minutes before continuing. Recharge the battery afterward.
