Operating Instructions for Robomule 3000/5000

  • Warning: This unit to be used by properly licensed AO mechanics only.
  • Always insure proper DC power available, minimum 150 amps at 28 VDC. The line cord from assembly to aircraft external power Is limited to 50 amps continuous max*, With 75 amps for three minutes.
  • When using hydraulic power stand always turn off avionics and engine computers to prevent damage from electrical spikes caused by on/off of motor and relays on hydraulic power stand. This Is especially important if aircraft is in maintenance without batteries installed. If batteries are installed, be sure they are tied to the external power buss. This will absorb most electrical spikes.
  • Always check motor remote control switch for proper operation before attachment of power stand to aircraft. Remote switch Is spring loaded to off position. Actuating remote motor switch should not run until you arm switch atop motor relay box assembly. Motor should run off and on by actuating switch with remote switch held on.
  • Warning: always check for proper directional rotation on the aircraft pump to match the hydraulic power stand rotation.
  • Warning: motor assembly is continuous duty. However, using motor over 10 minute period does increase wear appreciably. To assure long life, try to limit continuous duty operation whenever possible.
  • Warning: Always check to make sure personnel are clear of aircraft (landing gear, flaps, thrust reversers) before using power stand.
  • When installing pump on hydraulic motor drive pad, always make sure you are not kinking , pulling, or twisting hydraulic lines so as to cause damage. This can be done by adjusting stand assembly after aircraft has been jacked. (Always make sure safety pin on post and friction look "T" handles are locked on motor tilt pad and post.
  • Always remove hydraulic power stand before lowering aircraft.
