  1. When stowing your three piece remote pendant, it is recommended that you store the remote switch box portion in your vehicle. This will help preserve the new condition of the remote control and prevent theft.
  2. Remove the two-button pendant from the power unit at the quick disconnect.
  3. Mount the Power Unit using two, 3/8-16 UNC mounting bolts (Diagram A-2).
  4. Install 9/16-18 SAE ORB, SAE #6, hydraulic fitting into “P” port. Torque to 18 ft.-lbs.
  5. Connect the Hydraulic Line from the base of the cylinder to port “P”. Check the torque specification of the hosefittings (Diagram A-4).
  6. With the cylinder fully retracted, remove the Filler/Breather Cap and fill the reservoir with hydraulic fluidto “Full Line,” (see fluid recommendations).
  7. Connect the battery Ground cable to the Ground terminal of the DC Motor (Diagram A-3).
  8. Connect the Positive cable from the battery to the start solenoid (Diagram A-5).(Please see Battery Cable Gauge table for proper gauge for your length of cables.)
  9. Use a wrench to hold the bottom nut in place, to torque the upper nut (to 3 ft.-lbs.) to fasten the battery connections.
  10. Reconnect the two-button remote pendant at the quick disconnect.
  11. Fill the reservoir tank with the recommended hydraulic fluid, to the “Full Line” labeled on the side ofthe reservoir.

Do Not Mix Hydraulic Fluids.

KTI recommends using a premium hydraulic oil to ensure optimum performance and system life. Select oil that has anti-wear properties, rust and oxidation inhibitors, foam inhibitors and good stability. Examples of premium grade hydraulic oils: Chevron Rando HDZ, Mobil DTE 10, DTE 20 series, AMSOIL, and Shell Tellus.

Automotive Transmission Fluid (DEXTRON III) are acceptable under normal conditions.

Aviation Oils such as Valvoline ROYCO series or Mobil Aero HF or HFA may be used in prolonged, extreme cold environments.

Do Not Use Biodegradable Hydraulic Fluid with Buna seal, Biodegradable Hydraulic Fluid is compatible with Viton seals (optional).
